to preset with 2-stage models.)
Count inputs are not accepted while reset input is ON.
Reset indicator lit while reset input is ON.
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.)
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 indicator lit while key protection input is ON.
Effective when power supply is turned off.
Effective when protect terminals are shorted.
Outputs inhibit on the teaching mode.
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.
