I/O Functions Inputs Outputs CP1/CP2 Count signal inputs. Up, Down, and Up/Down (command, individual, or quadrature) inputs accepted. Reset Resets present value. (to zero in Up modes, to preset with 1-stage models in Down mode, and to preset with 2-stage models.) Count inputs are not accepted while reset input is ON. Reset indicator lit while reset input is ON. Compensation input (±Range type) On rising edge of up count signal, present count is reset to compensation value and, therefore, count inputs are accepted even if the compensation input is set to ON (not effective for down count signals.) Batch count reset (Standard type) Resets batch count to zero and batch output turns OFF. Signals are taken in on the ON edge. Batch count signals are not accepted while batch count reset is ON. Key protection Makes keys inoperative according to key protection level. Key protection indicator lit while key protection input is ON. Effective when power supply is turned off. Effective when protect terminals are shorted. Gate Inhibits counter operation when gate input is ON. OUT 1.2 Outputs made according to designated output mode when corresponding preset is reached. Outputs inhibit on the teaching mode. Batch output (Standard type) Outputs made when batch counter is up to preset number of batches. Batch output remains ON until batch count reset goes ON. When the number of batches is set to zero, batch counting is performed but batch outputs are not made. Batch counter counts the number of completed counts to the preset for 1-stage models and to preset 2 for 2-stage models. 5 H7BR H7BR Engineering Data Life Expectancy of Contacts Electrical Life Expectancy (Inductive Load) No. of operations (x 10 3 ) No. of operations (x 10 3 ) Electrical Life Expectancy (Resistive Load) 30 VDC (cos φ = 1) 250 VAC (cos φ = 1) 30 VDC (L/R = 7 ms) 250 VAC (cos φ = 0.4) Load current (A) Load current (A) Reference: A current of 0.15 A max. can be switched at 125 VDC (cos φ =1) and a current of 0.1 A max. can be switched if L/R = 7 ms.

Batch Counter Operation The batch counter counts the number of times set value is reached for 1-stage models, and the number of times set 2 is reached for 2-stage models. The batch count output holds until reset by the batch count reset. The present value of the batch count advances continuously. Batch count reset Batch count set value Batch count present value 0 Batch output 1. The batch count present value remains at 0 while the batch count reset is ON. When the batch count set value is 0, the batch count will proceed, but there will be no output. When the batch count present value exceeds 9999, it returns to 0. The batch count present value and output do not affect the RESET Key or reset input. 2. 3. 4. 5. 6. 7. When power is interrupted and the batch count output is ON, the output will be ON when power returns. When a batch count set value which is greater than the present value is changed to a set value which is less than the present value, the output will go ON. If, after the output has gone ON, the set value is changed to a set value which is greater than the present value, the output will remain ON.

When using a 24 VAC/12 to 24 VDC power supply type H7BR, reduce the load with the power supply voltage, as shown in the following diagram (When supplying external power). Load current (mA) • 160 • Display Error Output status Correction Function setting ĆĆĆĆĆĆ* Present value below min. No change Press RESET Key No change ffffff** Present value above max. e1 CPU e2 Memory 12 VDC 80 24 VDC 20 10 0 10 17 20 Supply voltage (VDC) 25 0 to 50 ms Input impossible 10 ms • Set at the factory When using the Counter in an area with much electronic noise, separate the Timer, wiring, and the equipment which generates the input signals as far as possible from the noise sources. It is also recommended to shield the input signal wiring to prevent electronic interference. • Organic solvents (such as paint thinner), as well as very acidic or basic solutions might damage the outer casing of the Counter. Possible 0 to 1.2 s Using the Prescale Function impossible Unstable • Press RESET Key • ON OFF OFF Operating Environment When turning the power ON and OFF, input signal reception is possible, unstable, or impossible as shown in the diagram below. The unstable period will vary with power supply voltage, and the load conditions on external power supplies. Power supply or reset input *Displayed when the present value has fallen below the min. value in the H7BR-C (±range type). **Displayed when the present value has exceeded the max. value in the H7BR-C (±range type). Power Supplies • The following displays will appear if an error occurs. The present value and output enter the same status as after pressing the RESET Key. A switching regulator is used in the internal circuits of counters with 100-to-240-VAC or 12-to-24-VAC specifications, causing an inrush current (approx. 1.5 A) to flow when power is turned on. If the capacity of the power supply to the counter is insufficient, the counter may not start operation. Be sure to provide adequate capacity (recommended supply capacity; 25 W min.) • When setting the prescale value, be sure that the set value satisfies this equation: set value “max. value - prescale value’. (if the prescale value is 1,250, 999.999 - 1,250 = 998.749 max.) • If a higher value is used, the output may be affected, so make sure that the output is produced before starting operation. Changing Set Values • Connect the power supply voltage through a relay or switch in such a way that the voltage reaches a fixed value immediately. DIP Switch Setting Changes Any changes in the DIP switch settings while power is being supplied is invalid. Restart the power supply. When changing the set value while the Counter is operating, the output will be produced if the set value ever equals the present value. To avoid triggering the output, begin by incrementing a higher digit to a large number. Resetting with a Set Value of 0 • When resetting is performed with the set value set to “0,” no output will be given for the safety reasons once the reset is turned OFF (except for the H7BR-C). 23 H7BR H7BR Output Delay Max. Count Speed of Batch Counter • The following table shows the delay from when the present value passes the set value until the output is produced. (The delay is the result of output control time, signal transmission time, relay switching time, etc.) Actual measurements in N and K modes. Control output Contact output 1, 2 Transistor output 1, 2 Batch outputs Max. counting speed • Output delay* The maximum count speed of the batch counter is 1 kHz {cps}. The batch counter counts the number of count-up times at the last stage (i.e., the number of preset-value counts if the H7BR is a one-stage model and the number of SET2 preset-value counts if the H7BR is a two-stage model). An interval of 1 ms or more is required before the batch counter counts up again after it has counted up. Response Delay Time for Resetting (Transistor Output) 30 Hz {cps} 18 to 24 ms 1 kHz {cps} 4.7 to 5.8 ms 5 kHz {cps} 4.4 to 5.4 ms 10 kHz {cps} 4.3 to 5.3 ms 30 Hz {cps} 13.5 to 20 ms 1 kHz {cps} 0.59 to 0.81 ms 1 ms 0.8 to 1.2 ms 5 kHz {cps} 0.29 to 0.44 ms 20 ms 15 to 25 ms 10 kHz {cps} 0.24 to 0.36 ms 30 Hz {cps} 13.6 to 20.2 ms 1 kHz {cps} 0.72 to 0.94 ms 5 kHz {cps} 0.42 to 0.57 ms 10 kHz {cps} 0.37 to 0.49 ms • Take the following output delays into consideration after the reset signal input is turned ON and the output is turned OFF. Minimum reset signal width Output delay time Other • When the Counter is installed in a control box and tests are conducted which may damage the Counter’s internal circuitry (for example, a test measuring the maximum voltage difference between the control circuit and metal components), remove the Counter from the control box or short-circuit the terminals. *The variation in delays is due to different modes and conditions. For systems where the delay is a problem, take actual measurements under operating conditions. ALL DIMENSIONS SHOWN ARE IN MILLIMETERS. To convert millimeters into inches, multiply by 0.03937.
