Depending on the operating environment, the condition of the Soft Cover may deteriorate, and it may shrink or become harder. Therefore, it is recommended that the Soft Cover is replaced regularly. 2. The H7CX’s panel surface is water-resistive (conforming to IP66) and so even if drops of water penetrate the gaps between the keys, there will be no adverse effect on internal circuits. If, however, there is a possibility of oil being present on the operator’s hands, use the Soft Cover. The Soft Cover ensures protection equivalent to IP54F against oil. Do not, however, use the H7CX in locations where it would come in direct contact with oil.

Doing so may result in explosion. The service life of the output relays depends on the switching capacity and switching conditions. Consider the actual application conditions and use the product within the rated load and electrical service life. Using the product beyond its service life may result in contact deposition or burning. Do not disassemble, repair, or modify the product. Doing so may result in electric shock, fire, or malfunction. Do not allow metal objects or conductive wires to enter the product. Doing so may result in electric shock, fire, or malfunction. + I Transistor Output The transistor output of the H7CX is isolated from the internal circuitry by a photocoupler, so the transistor output can be used as both NPN and PNP output. Counters NPN output PNP output Load Load + Power for load Power for load I External Power Supply The capacity of the external power supply is 100 mA at 12 V. When using a 24 VAC/12 to 24 VDC power supply, reduce the load with the power supply voltage, as shown in the following diagram (DC power supplies only). The diode connected to the collector of the output transistor is used to absorb inverted voltage that is generated when an inductive load is connected to the H7CX. Counter (DC v ltage Load current (mA) 100 ppl only) + Inductive load Power for load I Changing the Set Values When changing the set value during operation, because the H7CX uses a constant read-in system, output will turn ON if the set value is equal to the present value. I Operation with a Set Value and Present Value of 0 20 10.8 15 If the set value and present value are both 0, output will turn ON. Output will turn OFF during reset. C) Power pply vol age I Power Supplies When turning the power ON and OFF, input signal reception is possible, unstable, or impossible as shown in the diagram below. Power supply ON OFF 200 ms 0 to 90 ms 5 ms I Using the Prescaling Function 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). 0 to 1 s Impossible Unstable Input Impossible Possible Unstable • If the set value is set to a value greater than this, output will not turn ON. Note: Output will turn ON, however, if a present value overflow occurs (FFFFFF or FFFF). • Setting the prescale value incorrectly may result in incorrect counting operation. Be sure to set the prescale value correctly. Turn the power ON and OFF using a relay with a rated capacity of 10 A minimum to prevent contact deterioration due to inrush current caused by turning the power ON and OFF. Apply the power supply voltage through a relay or switch in such a way that the voltage reaches a fixed value immediately, otherwise they may not be reset or a counter error may result. Be sure that the capacity of the power supply is large enough, otherwise the counter may not start due to inrush current (reference value: approx. 10 A, 1.2 ms at 26.4 VAC) that may flow for an instant when the counter is turned ON. Make sure that the fluctuation of the supply voltage is within the permissible range. Make sure that the voltage applied is within the specified range, otherwise the internal elements of the counter may be damaged. I DIP Switch Setting Ensure that the power is turned OFF before changing DIP switch settings. Changing DIP switch settings with the power turned ON may result in electric shock due to contact with terminals subject to high voltages. I Power Failure Backup All data is stored in the EEPROM when there is power failure. The EEPROM can be overwritten more than 100,000 times. EEPROM is overwritten when the power is turned OFF or when settings are changed.

Occurs when the present value (or measurement value) reaches 999,999 (9,999 with 4-digit models) under the following conditions: • The output mode is K-2, D, L, or H. • The H7CX is set for dual counter or tachometer operation. 5. Except when the H7CX is set for tachometer operation. 6. Includes the case where the EEPROM has reached its overwrite lifetime. I Response Delay Time When Resetting (Transistor Output) The following table shows the delay from when the reset signal is input until the output is turned OFF. (Reference values) I Wiring Wiring input lines in the same conduit as power lines or other highvoltage lines may result in malfunction due to noise. Wire the input lines separately, away from lines carrying high-voltages. In addition, make the input wiring as short as possible and use shield lines or metal wiring conduits. Pay attention to terminal polarity to ensure correct wiring. Minimum reset signal width 1 ms 20 ms Output delay time 0.8 to 1.2 ms 15 to 25 ms I Mounting Tighten the two mounting screws on the Adaptor. Tighten them alternately, a little at a time, so as to keep them at an equal tightness. The H7CX’s panel surface is water-resistive (conforming to NEMA 4 and IP66). In order to prevent the internal circuit from water penetration through the space between the timer and operating panel, attach a waterproof packing between the timer and installation panel and secure the waterproof packing with the Y92F-30 Flush-mounting Adapter. 0.5 to 1 mm I Output Delay Time The following table shows the delay from when the present value passes the set value until the output is produced.

Note: The above times may vary slightly depending on the mode or operating conditions. I Maximum Counting Speed for Batch Counter The maximum counting speed for batch counter operation is 5 kHz. The batch counter counts the number of times the count reaches the set value. C-104 Multifunction Preset Counter H7CX I Operating Environment • Use the product within the ratings specified for submerging in water and exposure to oil. • Do not use the product in locations subject to vibrations or shocks. Using the product in such locations over a long period may result in damage due to stress. • Do not use the product in locations subject to dust, corrosive gases, or direct sunlight. • Separate the input signal devices, input signal cables, and the product from the source of noise or high-tension cables producing noise. • Separate the product from the source of static electricity when using the product in an environment where a large amount of static electricity is produced (e.g., forming compounds, powders, or fluid materials being transported by pipe). • Organic solvents (such as paint thinner), as well as very acidic or basic solutions might damage the outer casing of the H7CX. • Use the product within the ratings specified for temperature and humidity. • Do not use the product in locations where condensation may occur due to high humidity or where temperature changes are severe. • Store at the specified temperature. If the H7CX has been stored at a temperature of less than -10°C, allow the H7CX to stand at room temperature for at least 3 hours before use. • Leaving the H7CX with outputs ON at a high temperature for a long time may hasten the degradation of internal parts (such as electrolytic capacitors). Therefore, use the product in combination with relays and avoid leaving the product as long as more than 1 month with the output turned ON. X2/b T/a X1/a X1/a T X1 X X2 Auxiliary relay (e.g., MY Relay) • The load current must be within the rated current. I Insulation • Specifications call for basic insulation between the power supply and input terminals, between the power supply and output terminals, and between the input and output terminals. (The H7CX-A@D is not insulated between the power supply and input terminals.) • Input and output terminals are connected to devices without exposed charged parts. • Input and output terminals are connected to devices with basic insulation that is suitable for the maximum operating voltage.

Set increment mode (UP), decrement mode (DOWN), or one of the increment/decrement modes (UP/DOWN A, UP/DOWN B, or UP/ DOWN C) as the input mode. Input modes other than UP or DOWN modes cannot be set using the DIP switch and so 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 112.) Prescale Value (pscl) Pulses input to the counter are converted according to the specified prescale value. (Setting range: 0.001 to 99.999 for 6-digit models and 0.001 to 9.999 for 4-digit models.) Example: To display the feed distance for systems that output 25 pulses for a feed length of 0.5 m in the form @@.@@ m: 2. Set the prescale value to 0.02 (0.5÷25). 0.5 m Dual Count Calculating Mode (calm) When using as a dual counter, select either ADD (addition) or SUB (subtraction) as the calculation method for the dual count value. SUB mode can be used only when K-2, D, L, or H is selected as the output mode with 6-digit models. ADD: SUB: Dual count value = CP1 PV + CP2 PV Dual count value = CP1 PV − CP2 PV Output Mode (outm) (Setting possible using DIP switch.) 25 pulses 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 and so 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 113.) Encoder NPN/PNP Input Mode (imod) Select either NPN input (no-voltage input) or PNP input (voltage input) as the input format. The same setting is used for all external inputs. For details on input connections, refer to Input Connection on page 96. One-shot Output Time (otim) (Setting possible using DIP switch.) Set the one-shot output time (0.01 to 99.99 s) for control output. 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 and so use the operation keys if other settings are required. Display Color (colr) Set the color used for the present value. Output OFF (See note.) red Red (fixed) Green (fixed) Red Green Green Red grn r-g g-r Output ON (See note.) One-shot Output 2 Time (otm2) (Setting possible using DIP switch.) When 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). 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 and so use the operation keys if other settings are required. Note: When using as a 2-stage counter, this is the status of output 2. Output Allocation (otst) When using H7CX-AU@ models as a 2-stage counter, the output can be flexibly allocated to either stage 1 or 2. Transistor output can be allocated to SV1 and contact output for SV2 or vice verse, as in the following table. One-shot Output 1 Time (otm1) When using as a 2-stage counter, set the one-shot output time (0.01 to 99.99 s) for control output (OUT1).

Multifunction Preset Counter H7CX (Counter Function) C-115 Counters Total and Preset Counter Operation The H7CX has a total counter, separate from the 1-stage preset counter, for counting the total accumulated value. Reset/reset 1 Total reset/reset 2 Present value 0 999999 Total count value 0 Note: The full scale (FS) for H7CX 4-digit models is 9999. • 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 (−999 to 9,999). The total count value returns to 0 when it reaches the full scale limit. Batch Counter Operation The H7CX has a batch counter, separate from the 1-stage preset counter, for counting the number of times the count has been completed. Reset 1 Reset 2 (batch counter reset) Set value Present value 0 OUT2 Batch count set value Batch count value 0 • The batch counter continues after count completion. • Batch output is held until batch counter reset is input. • 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. 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 during batch counter reset input. 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 (9,999 for 4-digit models). 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. C-116 Multifunction Preset Counter H7CX (Counter Function) 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. OUT1 and OUT2 turn ON and OFF simultaneously. Dual Count Calculating Mode = ADD Dual count value = CP1 PV + CP2 PV Reset 1 (CP1 reset) Reset 2 (CP2 reset) Dual count set value Dual count value 0 Dual Count Calculating Mode = SUB Dual count value = CP1 PV − CP2 PV Reset 1 (CP1 reset) Reset 2 (CP2 reset) Dual count value Dual count set value 0 CP1 present value CP1 present value 0 0 CP2 present value 0 CP2 present value 0 • 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 outputs turn OFF. At this time, counting is not possible for CP1 or CP2 inputs. OUT1, 2 OUT1, 2 Note: The above is for when the output mode is N. 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 during reset 1 input. CP2 will not be affected. The dual count value will be calculated based on a CP1 present value of 0. 2. Counting is not possible for CP2 during reset 2 input. CP1 will not be 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 (−999 to 9,999 for 4-digit models). The counting ranges for the CP1 present value and CP2 present value are 0 to 999,999 (0 to 9,999 for 4-digit models). If a present value exceeds 999,999 (9,999 for 4digit models), FFFFFF (FFFF for 4-digit models) will be displayed to indicate an overflow, and all counting will stop.

Changes to DIP switch settings are enabled when the power is turned ON. Advanced-Function Settings After making DIP switch settings for basic operations, advanced-functions (see note) can be added using the operation keys. For details, refer to page 34. Note: Advanced functions consist of decimal point position, prescale value, auto-zero time, startup time, display color, output allocation, and key protect level. C-118 Multifunction Preset Counter H7CX (Tachometer Function) Settings for Advanced Functions Note: When using as a tachometer, switch to the tachometer configuration using the procedure given on page 124.

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 123.) Auto-zero Time (aut=) It is possible to set the H7CX 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 and within the setting range (0.1 to 99.9 s). 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. Counting Speed (cnts) (Setting possible using DIP switch.) 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. 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 (0.0 to 99.9 s), 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 H7CX and rotating body are turned ON at the same time. Display Startup time 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 H7CX 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 × a f: Input pulse frequency (number of pulses in 1 second) a: Prescale value 1. Displaying Rotation Rate Display unit rpm rps N: Number of pulses per revolution Example:In order to display the rate of rotation for a machine that outputs 5 pulses per revolution in the form @@.@ rpm: 1.

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. Average Processing (aug) (Setting possible using DIP switch.) Flickering display and output chattering can be prevented using average processing (simple averaging). Average processing can be set to one of four levels: no average processing, 2 times (i.e., the average of 2 measurement values), 4 times, or 8 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.

Indicates that DIP switch pin 2 is ON. Indicates that DIP switch pin 1 is ON. Note: 1. When the mode is changed to configuration selection mode, the present value is reset, outputs turns OFF, and counting (measuring) stops. 2. Setting changes made in configuration selection mode are enabled when the mode is changed to run mode. If the configuration is changed, the set value (or set value 1 and set value 2), OUT1 set value or OUT2 set value are initialized.
