Input modes other than UP or DOWN modes cannot be set using the DIP switch. Use the operation keys if other modes are required. (For details on the operation of the input modes, refer to Input Modes and Present Value on page 16.) Set the reset input signal width (20 ms/1 ms) for reset/reset 1 and total reset/reset 2 inputs together. If contacts are used for input signals, set the counting speed to 20 ms. Processing to eliminate chattering is performed for this setting. • Dual Count Calculating Mode (calm) When the H7BX using as a dual counter, select either ADD (addition) or SUB (subtraction) as the calculation method for the dual count value. ADD: Dual count value = CP1 PV + CP2 PV SUB: Dual count value = CP1 PV − CP2 PV • Output Mode (outm) ★ Set the way that control output for the present value is output. The possible settings are N, F, C, R, K-1, P, Q, A, K-2, D, L, and H. Output modes other than N, F, C, or K-1 cannot be set using the DIP switch. Use the operation keys if other modes are required. The output modes that can be set vary with the model. (For details on the operation of the output modes, refer to Input/Output Mode Settings on page 18.) • Decimal Point Position (dp) Decide the decimal point position for the present value, CP1/CP2 present values, set values (SV1, SV2), total count value, dual count value and dual count set value. • Prescale Value (pscl) Pulses input to the counter are converted according to the specified prescale value. Setting range: 0.001 to 99.999 Example: To display the feed distance for systems that output 25 pulses for a feed length of 0.5 m in the form @@.@@ m: 1. Set the decimal point position to 2 decimal places. 2. Set the prescale value to 0.02 (0.5 ÷ 25). 0.5 m • One-shot Output Time (otim) ★ Set the one-shot output time (0.01 to 99.99 s) for the control output. A one-shot output can be used only when C, R, K-1, P, Q, A, or K-2 is selected as the output mode. Output times other than 0.5 s or 0.05 s cannot be set with the DIP switch. Use the operation keys if other settings are required. • One-shot Output 2 Time (otm2) ★ When the H7BX using as a 2-stage counter or batch counter, set the one-shot output time (0.01 to 99.99 s) for control output (OUT2). A one-shot output can be used only when C, R, K-1, P, Q, A, or K-2 is selected as the output mode. Output times other than 0.5 s or 0.05 s cannot be set with the DIP switch. Use the operation keys if other settings are required. • One-shot Output 1 Time (otm1) When the H7BX using as a 2-stage counter, set the one-shot output time (0.01 to 99.99 s) for control output (OUT1). A one-shot output can be used only when D, L, or H is selected as the output mode. If the output time is set to 0.00, hold is displayed, and outputs are held. • Counting Speed (cnts) ★ Set the maximum counting speed (30 Hz/5 kHz) for CP1 and CP2 inputs together. If contacts are used for input signals, set the counting speed to 30 Hz. Processing to eliminate chattering is performed for this setting. 25 pulses Encoder Note: Incorrectly setting the prescale value will result in counting errors. Check that the setting has been performed correctly before using the H7BX. • NPN/PNP Input Mode (imod) ★ Select either NPN input (no-voltage input) or PNP input (voltage input) as the input format. For 2-wire sensors, set the format to NPN input. The same format setting applies to all external inputs. For information on input connections, refer to page 6. • Display Color (colr) Set the color used for the present value. Output OFF * Output ON * Red (fixed) red Green (fixed) grn r-g Red Green g-r Green Red * When the H7BX using as a 2-stage counter, this is the status of output 2. 13 H7BX • Absolute Value Setting/Forecast Value Setting (setm) • Memory back up (bkup) For the 2 count output mode, an absolute value setting (abs) or forecast value setting (ofst) can be set for set value 1. If the absolute value setting is used, specify an absolute value (deviation from 0). Set the present value and the output state memory backup. If memory backup is available, the present value and output state are recovered to the state prior to power interruption. If memory backup is not available, the present value and output state are recovered to the reset state. Example: F Mode Count value • H7AN Compatibility Function (h7an) Set value 2 Set value 1 0 Control output 1 (OUT1) Control output 2 (OUT2) If the forecast value setting is used, specify set value 1 as the forecast set value (deviation with respect to set value 2). The forecast output (output 1) turns ON when the present value reaches the forecast value. If the forecast set value is greater than or equal to the set value, the forecast output (output 1) will turn ON as soon as counting starts. Example: F Mode Count value Set value Forecast set value Forecast value 0 Forecast output (OUT1) Control output (OUT 2) When the present value being decremented exceeds 0, make the setting to start counting from 999999. When this function is ON, the value becomes 999999 after 0, and when this function is OFF, the count is in accordance with the output mode. The H7AN Compatibility Function is enabled only when 1-stage preset counter, 2-stage preset counter, and total and preset counter are selected, and is displayed in the function setting mode. It is not displayed when batch counter, dual counter, or twin counter are selected. This function enables the same operation when the H7AN is replaced with the H7BX. • Output ON Count Alarm Set Value (on-a, on1a, on2a) The output ON count for notifying the replacement time can be set. For details, refer to page 35. • Output ON Count Monitor Value (on-c) The monitor value is only displayed. It cannot be set. The output ON count will be 1,000 times the displayed value. • ON Count Monitor Values for Outputs 1 and 2 (OUT1 and OUT2) (on1c and on2c) The monitor value for output 1 and 2 (OUT1 and OUT2) is only displayed. It cannot be set. The output ON count will be 1,000 times the displayed value. • Set Value Upper Limit (sl-h) • Cumulative Run Time Alarm Set Value (ot-a) Set the upper limit for the set value when it is set in run mode. The cumulative run time for notifying the replacement time can be set. For details, refer to page 35. • Forecast Set Upper Limit (pl-h) Set the upper limit for the forecast set value. • Batch Count Upper Limit (bl-h) • Cumulative Run Time Monitor (ot-c) The cumulative run time is displayed. It is not a setting item. The numerical values are displayed in increments of 0.1 years. Set the upper limit for the batch count value. • Output Allocation (Settings applicable to only H7BX-AW) (otst) Set the allocation of outputs 1 and 2 (OUT1 and OUT2). If output allocation is OFF, output 1 (OUT1) is allocated to terminals (5)-(6), (14)-(17), and output 2 (OUT2) is allocated to terminals (3)-(4), (14)(18). If output allocation is ON, output 1 (OUT1) is allocated to terminals (3)-(4), (14)-(18), and output 2 (OUT2) is allocated to terminals (5)-(6), (14)-(17). • Key Protect Level (kypt) Set the key protect level. Refer to Key Protect Level on page 34. • Output inversion (ot-i, ot1i, ot2i) Set logical inversion of output ON/OFF. In the case of two outputs, it is possible to individually set output inversion for each of output 1 and output 2 (OUT1 and OUT2). If output inversion is n-o (Normally Open), the output turns ON when the set value is reached. If output inversion is n-c (Normally close), the output turns OFF when the set value is reached. 14 H7BX Operation in Run Mode I/O Functions for Counter Operation • Set values for each digit as required using the Up Keys. 1-stage Preset Counter 0 0 Total and Preset Counter Present value 2-stage Preset Counter with Absolute Value Setting 0 0 0 0 Present value Set value 1 Present value • Set Values (Set Value 1 and Set Value 2) Set the set values.

The set values are between −99999 and 999999. 22 H7BX Total and Preset Counter Operation The H7BX has a total counter separate from the 1-stage preset counter for counting the total accumulated value. • The total counter continues to count the total accumulated value when the present value is reset using reset/reset 1 input (Reset Key). • The total count value is reset when the total reset/ reset 2 input is turned ON. If the Reset Key is pressed while the total count value is displayed, the total count value is reset. The present value is also reset at this time. • The counting range of the total counter is −99,999 to 999,999. The total count value returns to 0 when it reaches the full scale limit. Reset/reset 1 Total reset/reset 2 Present value 0 999999 Total count value 0 Batch Counter Operation The H7BX has a batch counter separate from the 1-stage preset counter for counting the number of times the count has been completed. Reset 1 • The batch counter continues after count completion. • Batch output is held until batch counter reset input turns ON. • When the batch counter reset input is turned ON, the batch count value is reset, and batch output turns OFF. • If the Reset Key is pressed while the batch count value is displayed, the batch count value is reset and batch output turns OFF. The present value is also reset at this time. • The maximum counting speed for batch counter operation is 5 kHz. Reset 2 (batch counter reset) Set value Present value 0 OUT2 Batch count set value (Sub-display) Batch count value (Main display) 0 2 1 OUT1 (batch output) Note: The above is for when the output mode is C. Note: 1. 2. 3. 4. 5. 6. The batch count value is held at 0 while the batch counter reset input is on. If the batch count set value is 0, batch count will be performed but there will be no batch output. The batch count value returns to 0 when it reaches 999,999. Once batch input has been turned ON, it will return to the ON state after power interruptions. If the batch count set value is changed from a value that is greater than the batch count value to one that is less, batch output will turn ON. After batch output turns ON, the ON state will be held even if the batch count set value is changed to a value greater than the batch count value. Dual Counter Operation Using the dual counter allows the count from 2 inputs to be added or subtracted and the result displayed. It is possible to specify a set value for which output turns ON when the set value matches the added or subtracted result. (1) Dual Count Calculating Mode = ADD Dual count value = CP1 PV + CP2 PV (2) Dual Count Calculating Mode = SUB Dual count value = CP1 PV - CP2 PV Reset 1 (CP1 reset) Reset 1 (CP1 reset) Reset 2 (CP2 reset) Reset 2 (CP2 reset) Dual count set value Dual count set value Dual count value Dual count value 0 0 CP1 present value CP1 present value 0 0 CP2 present value CP2 present value 0 0 OUT1, 2 Note: The above is for when the output mode is N. • The operation after count completion for the dual counter value is determined by the output mode. • The CP1 present value is reset when reset 1 input is turned ON and the CP2 present value is reset when reset 2 input is turned ON. • If the Reset Key is pressed while the dual count value, CP1 present value, or CP2 present value is displayed, all of the present values are reset and the outputs turn OFF. At this time, counting is not possible for CP1 or CP2 inputs. OUT1, 2 Note: The above is for when the output mode is K-2. SUB mode can be used only when K-2, D, L, or H is selected as the output mode with 6-digit models. Note: 1. Counting is not possible for CP1 while the reset 1 input is ON. CP2 is not affected. The dual count value will be calculated based on a CP1 present value of 0. 2. Counting is not possible for CP2 while the reset 2 input is ON. CP1 is not affected. The dual count value will be calculated based on a CP2 present value of 0. 3. The counting range for the dual count value is −99,999 to 999,999. The counting ranges for the CP1 present value and CP2 present value are 0 to 999,999. If a present value exceeds 999,999, FFFFFF will be displayed to indicate an overflow, and all counting will stop. If a present value goes below -999999, "------" will be displayed and all counting will stop. 23 H7BX Twin Counter Operation Two independent counters are built in.

Input mode Internal processing Input Application 1 input Count 1 None Operation with only one input. 2 inputs Counts 1 and 2 None Operation with two independent inputs. Error Counts 1 and 2 Count 1 input − Count 2 input Measuring the difference between two inputs (error in number of revolutions). Absolute ratio Counts 1 and 2 Count 1 input ÷ Count 2 input Measuring the ratio of two inputs (ratio of number of revolutions). Error ratio Counts 1 and 2 (Count 1 input − Count 2 input) ÷ Count 2 input Measuring the ratio of error for two inputs (measuring the error ratio of number of revolutions). • Tachometer Output Mode (totm) ★ Set the output method for control output based on the OUT1/OUT2 set value. Upper and lower limit (HI-LO), area (AREA), upper limit (HI-HI), and lower limit (LO-LO) can be set. (For details on the operation of the output modes, refer to Output Mode Settings on page 32.) • Counting Speed (cnts) ★ Set the maximum counting speed (30 Hz/10 kHz) for CP1 input. If contacts are used for input signals, set the counting speed to 30 Hz. Processing to eliminate chattering is performed for this setting. • Decimal Point Position (dp) Decide the decimal point position for the measurement value, OUT1 set value, and OUT2 set value. • Prescale Value (pscl) It is possible to display the rate of rotation or the speed of a device or machine to which the H7BX is mounted by converting input pulses to a desired unit. If this prescaling function is not used, the input frequency (Hz) will be displayed. The relationship between display and input is determined by the following equation. Set the prescale value according to the unit to be displayed. Displayed value = f × α f: Input pulse frequency (number of pulses in 1 second) α: Prescale value 1. Displaying the Rotation Rate Display unit Prescale value (α) rpm 1/N × 60 rps 1/N N: Number of pulses per revolution • Observe the following points when setting a prescale value. Set the set value to a value less than {Maximum countable value − Prescale value}. Example: If the prescale value is 1.25 and the counting range is 0.000 to 999.999, set the set value to a value less than 998.749 (= 999.999 − 1.25). If the set value is set to a value greater than this, output will not turn ON. • Output will turn ON, however, if a present value overflow occurs (FFFFFF). Note: Incorrectly setting the prescale value will result in counting errors. Check that the setting has been performed correctly before using the H7BX. • Averaging Method (avgt) A simple average or moving average can be selected for the averaging. With the moving average method, the average of the measurement values is displayed each sampling cycle, in contrast to a simple average, with which the average of the set number of samples is displayed. • Average Processing (avgn) ★ Flickering display and output chattering can be prevented by using average processing (simple averaging). Average processing can be set to one of five levels: no average processing, 2 times (i.e., the average of 2 measurement values), 4 times, 8 times or 16 times. The measurement cycle will be equal to the sampling cycle (200 ms) multiplied by the average processing setting (i.e., the number of times). Average processing enables fluctuating input signals to be displayed stably. Set the optimum number of times for the application. • Auto-zero Time (aVto0) It is possible to set the H7BX so that if there is no pulse for a certain time the display is force-set to 0. This time is called the auto-zero time. Set the auto-zero time to a time slightly longer than the estimated interval between input pulses. It will not be possible to make accurate measurements if the auto-zero time is set to a time shorter than the input pulse cycle. Setting a time that is too long may also result in problems, such as a time-lag between rotation stopping and the alarm turning ON. • Startup Time (stmr) In order to prevent undesired output resulting from unstable input immediately after the power supply is turned ON, it is possible to prohibit measurement for a set time. This time is called the startup time. It can also be used to stop measurement and disable output until the rotating body reaches the normal rate of rotation, after the power supply to the H7BX and rotating body are turned ON at the same time. Display Example: In order to display the rate of rotation for a machine that outputs 5 pulses per revolution in the form @@.@ rpm: 1. Set the decimal point position to 1 decimal place. 2. Using the formula, set the prescale value to 1/N × 60 = 60/5 = 12. Startup time Comparison value (lower limit) Time 2. Displaying the Speed Power supply Display unit Prescale value (α) m/min πd × 1/N × 60 m/s πd × 1/N N: Number of pulses per revolution d: Diameter of rotating body (m) πd: Circumference (m) Output (lower limit) • NPN/PNP Input Mode (imod) ★ d: Diameter of rotating body Select either NPN input (no-voltage input) or PNP input (voltage input) as the input format. Select an NPN input when using a 2-wire sensor. The same setting is used for all external inputs. For details on input connections, refer to Input Connections on page 6. 29 H7BX • Peak/bottom Hold Enabled (dhld) • Output inversion (ot1i, ot2i) This function records the peak and bottom (i.e., minimum) after counting starts (after turning ON the power supply or changing the configuration selection mode or function setting). The peak value is also held when the power supply is interrupted. • Output Hysteresis (hys) Set logical inversion of output ON/OFF. In the case of two outputs, it is possible to individually set output inversion for each of output 1 and output 2 (OUT1 and OUT2). If output inversion is n-o (Normally Open), the output turns ON when the set value is reached. If output inversion is n-c (Normally close), the output turns OFF when the set value is reached. This setting can be used to prevent output chattering if the measurement value fluctuates slightly near the set value. The measurement value after prescaling is set. • Pulse Cycle Measurement/Pulse Width Measurement (calm) Comparison value 2 Hysteresis Display value Hysteresis Comparison value 1 OUTX1 OUTY2 Set the hysteresis for when the output turns OFF. • Output OFF Delay (offd) This function delays the timing for turning OFF comparative output by a certain time. The ON time can be held for the set time if the comparative result changes in a short time. Operation will continue and outputs will not change when holding the value. Set the measurement mode to pulse cycle measurement or pulse width measurement. With pulse cycle measurement, the number of pulse cycles that occur in 1 s is measured. With pulse width measurement, the ON time for one pulse is measured. An input OFF period of at least 20 ms is required for pulse width measurement. If there is no input pulse during pulse width measurement, the previously measured value will be held. • Display Unit (unit) When pulse cycle measurement is used, set the display unit to Hz (hertz) or s (seconds). • Counting Interval (intv) If the measurement speed is 10 kHz when pulse cycle measurement is used, set the measurement interval to 200 ms or Cont (10 ms min.). • Set Value Upper Limit (sl-h) • ON Count Alarm Set Values for Outputs 1 and 2 (OUT1 and OUT2) (on1a and on2a) Set the upper limit for the set value when it is set in run mode. The limit can be set to between 1 and 999999. The output ON count for notifying the replacement time can be set. For details, refer to page 35. • Display Color (colr) • ON Count Monitor Values for Outputs 1 and 2 (OUT1 and OUT2) (on1c and on2c) Set the color used for the measurement value. Control output OFF Control output ON red Red (fixed) grn Green (fixed) r-g *1 Measured value displayed in red when both control outputs 1 and 2 are OFF. Measured value displayed in green when either control output 1 or control output 2 is ON. g-r *2 Measured value displayed in green when both control outputs 1 and 2 are OFF. Measured value displayed in red when either control output 1 or control output 2 is ON. The monitor value for output 1 and 2 (OUT1 and OUT2) is only displayed. It cannot be set. The output ON count will be 1,000 times the displayed value. • Cumulative Run Time Alarm Set Value (ot-a) The cumulative run time for notifying the replacement time can be set. For details, refer to page 35. • Cumulative Run Time Monitor (ot-c) The cumulative run time is displayed. It is not a setting item. The numerical values are displayed in increments of 0.1 years. *1. If the tachometer output mode is set to AREA, however, the measured value is displayed in red when control output 1 is OFF and in green when control output 1 is ON. *2. If the tachometer output mode is set to AREA, however, the measured value is displayed in green when control output 1 is OFF and in red when control output 1 is ON. • Output Allocation (Settings applicable to only H7BX-AW) (otst) Set the allocation of outputs 1 and 2 (OUT1 and OUT2). If output allocation is OFF, output 1 (OUT1) is allocated to terminals (5)-(6), (14)-(17), and output 2 (OUT2) is allocated to terminals (3)-(4), (14)(18). If output allocation is ON, output 1 (OUT1) is allocated to terminals (3)-(4), (14)-(18), and output 2 (OUT2) is allocated to terminals (5)-(6), (14)-(17). • Key Protect Level (kypt) Set the key protect level. For details, refer to Key Protect Level on page 34. 30 H7BX Operation in Run Mode • Set the number for each digit with the Up Keys. *1 • Measurement Value Displays the currently measured value.

The H7BX is equipped with a function for notifying the replacement time by the cumulative run time and ON count of the relay contact. When either the cumulative run time or ON count of the relay contact reaches the replacement time, Rplc (REPLACE) can be displayed on the Timer. For details on RPLC display, refer to Self-diagnosis Function on this page. Output ON Count Alarm Set Value (on-a, on1a, on2a) Set the alarm value for the output ON count. The limit can be set between 0×1000 (0 times) and 9999×1000 (9,999,000 times). Only the underlined values are set. The alarm will be disabled if 0 is set. 100,000 times is set in the default settings. If the total output ON count reaches the alarm set value or above, an RPLC (replacement time) error can be displayed on the Timer. Cumulative Run Time Alarm Set Value (ot-a) The cumulative run time can be set in a range from 0.0 to 99.9 years. The replacement time notification function is disabled if 0 is set. 10 years is set in the default settings. If the cumulative run time reaches the alarm set value or above, an RPLC (replacement time) error can be displayed on the Timer. Self-diagnostic Function The following displays will appear if an error occurs. Output status Correction method Set value after reset Present value underflow *2 No change Either perform reset key or turn ON reset input. *5 No change Present value overflow *3 No change Either perform reset key or turn ON reset input. *5 No change OFF Either perform reset key or reset the power supply.

This occurs in the following conditions if the present value (i.e., measurement value) exceeds 999999. • For Output Modes K-2, D, L, or H • Dual counter or tachometer operation is used. *4. Display flashes.(1-second cycles) *5. This does not apply when tachometer operation is used. *6. This is displayed if the alarm value setting for either of the two outputs is exceeded if a model with two outputs is used.The total ON count will not be cleared by reset operation. *7. The normal display and Rplc will appear alternately. When reset operation is performed, Rplc will not be displayed even if the alarm set value is exceeded. (Monitoring is possible, however, because the counter will continue without the cumulative run time and output ON count being cleared.) Rplc is displayed again if the power is turned OFF/ON after the Rplc display is cleared during recovery by the reset operation. If you do not want to display Rplc when the power is turned OFF/ON, either change the alarm set value to the present value or above, or change the alarm set value to 0 to disable it. 35 H7BX Safety Precautions Refer to Safety Precautions for All Counters. Caution Minor injury due to electric shock may occasionally occur. Do not touch any of the terminals while power is being supplied. Fire may occasionally occur. Tighten the terminal screws to a torque of 0.5 to 0.6 N·m (4.4 to 5.3 in-lb). Minor injury due to explosion may occasionally occur. Do not use the H7BX where subject to flammable or explosive gas. If the output relay is used beyond its life expectancy, its contacts may become fused or there may be a risk of fire. Use the output relay within its rated load and electrical life expectancy. The life expectancy of the output relay varies considerably according to its usage. Minor electric shock, fire, or malfunction may occasionally occur. Never attempt to disassemble, modify, or repair the H7BX or touch any of the internal parts. Precautions for Safe Use Operating Environment • The H7BX is intended for indoor use only. Do not use the H7BX outdoors or in any of the following locations. • Locations subject to sudden or extreme changes in temperature. • Locations where high humidity may result in condensation. • Locations subject to direct sunlight. • Locations subject to corrosive gas. • Locations subject to excessive dust or dirt. • This is a class A product (for industrial environments). In residential areas, it may cause radio interference, in which case the user may be required to take adequate measures to reduce interference. • Use the H7BX within the specified ratings for operating temperature and humidity. Temperature rise may shorten the service life of H7BX if it is used near a power supply or other heat-generating objects. • Use the H7BX within the specified ratings for vibration, shock, and splashing water. • The H7BX is not oil resistant. Do not use it in locations subject to oil. • Install the H7BX well away from any sources of excessive static electricity, such as pipes transporting molding materials, power, or liquids. • Store the H7BX within the specified ratings. If the H7BX has been stored at temperatures of −10°C or lower, let it stand for 3 hours or longer at room temperature before turning ON the power supply. Power Supply • Maintain voltage fluctuations in the power supply within the specified range. • Internal elements may be destroyed if a voltage beyond the rated voltage is applied. • When the power is turned ON, an inrush current will flow for a short time (approx. 10 A for 2 ms). Depending on the power supply capacity, operation may not start. Be sure to use a power supply with a sufficient capacity. • Use a commercial power supply as the AC power supply for the H7BX. Using an inverter output with an output frequency of 50/60 Hz as the power supply may cause the H7BX to produce smoke or become damaged by burning. • Use a switch, relay, or other device with contacts so that the rated power supply voltage will be reached within 2 s. If the power supply voltage is not reached quickly enough, the outputs may malfunction. • Use a switch, relay, or other device with contacts so that the rated power supply voltage will be reached within 2 s. If the power supply voltage is not reached quickly enough, the outputs may malfunction. Installation and Wiring • To mount the H7BX to a panel, attach the two supplied adapters to the left and right sides of the H7BX, and securely tighten the knurled screws on the adapters by hand, maintaining a balance between them. Damage may result if the knurled screws are excessively tightened with pliers or other tools. • Be sure to wire the terminals correctly. • Up to two wires of the same size and type can be inserted into a single terminal. • Do not connect more than two crimp terminals to each H7BX terminal. • Use the specified wires for wiring. Applicable wire: AWG 24 to AWG 18 (equal to a cross-sectional area of 0.20 to 0.82 mm2) Solid wire or twisted wire (copper), operating temperature over 70°C. • Separate the H7BX, the devices that generate input signals, and input signal wires from any potential sources of noise, such as high-voltage lines. Handling • Do not use organic solvents (such as paint thinner or benzine), strong alkaline, or strong acids because they will damage the external finish. • Approximately 14 V will be output to the input terminals when the H7BX is used with the key protection input terminals and no-voltage input (NPN input) is used. To prevent charging accidents, connect a diode to the power supply circuit of input devices if input devices are used with a power supply of less than 14 V. • Do not connect loads that exceed the rated output current. The output elements may be destroyed, possibly resulting in short-circuit or open-circuit faults. • When using heaters, be sure to use a thermal switch for the load circuit. • Always connect a diode to protect against counter electromotive force when using an inductive load. H7BX electromotive force may destroy output elements, possibly resulting in short-circuit or open-circuit faults. • Install a switch or circuit breaker that allows the operator to immediately turn OFF the power, and label it to clearly indicate its function. • Check that the display (backlight and LCD) is operating normally. Some operating environments may accelerate deterioration of the indicators, LCD, and resin components and cause display malfunctions. Periodically inspect and replace parts. 36 H7BX Precautions for Correct Use • Inrush current generated by turning ON or OFF the power supply may deteriorate contacts in the power supply circuit. Turn ON or OFF using a device with a rated current of 10 A or higher. • Input signals may be accepted, not accepted, or unstable for the following time when the power supply is turned ON or OFF. Set the system to allow leeway in the timing of input signals. Power supply ON OFF 200 ms 0 to 90 ms Input Impossible Unstable 5 ms Possible 0 to 1 s Unstable Impossible Load current (mA) • This H7BX always compares the count value with the set value. Thus, if you change the set value during operation, please remember that the output will turn ON when the set value becomes equal to the count value. • With the factory setting, the output will turn ON when power is supplied to the H7BX because the set value and count value are both zero. While resetting, however, the output stays OFF. • Non-volatile memory is used as memory when the power is interrupted. The write life of the Non-volatile memory is 100,000 writes. The Non-volatile memory is written when settings are changed, or the power is tuned OFF. • Water resistance will be lost if the front sheet is peeled off or torn. Do not use the H7BX if the front sheet is missing or torn. • Abide by all local ordinances and regulations when disposing of the H7BX. • External Power Supply Reduce the load current as shown in the diagram on the right according to the power supply voltage if a DC power supply is used for models specified for 24 VAC/12 to 24 VDC. 100 20 0 10.8 15 Power supply voltage (VDC) 37 Terms and Conditions Agreement Read and understand this catalog.
