Reset indicator lit while reset input is ON. Compensation input On rising edge of up count signal, present count is reset to compensation value and, therefore, (±Range type) count inputs are accepted even if the compensation input is set to ON (not effective for down count signals.) Batch count reset Resets batch count to zero and batch output turns OFF. (Standard type) 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. Outputs OUT 1.2 Outputs made according to designated output mode when corresponding preset is reached. Outputs inhibit on the teaching mode. Batch output Outputs made when batch counter is up to preset number of batches. (Standard type) 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 Electrical Life Expectancy (Resistive Load) (Inductive Load) 30 VDC (cos φ = 1) 30 VDC (L/R = 7 ms) 250 VAC (cos φ = 1) 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.

(if the prescale value is 1,250, 999.999 - 1,250 = 998.749 max.) • A switching regulator is used in the internal circuits of counters • If a higher value is used, the output may be affected, so make 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. sure that the output is produced before starting operation. If the capacity of the power supply to the counter is insufficient, Changing Set Values the counter may not start operation. Be sure to provide adequate capacity (recommended supply capacity; 25 W min.) • When changing the set value while the Counter is operating, the output will be produced if the set value ever equals the present • Connect the power supply voltage through a relay or switch in value.
