Power circuits *
Count signal inputs.
Up, Down, and Up/Down (command, individual, or quadrature) inputs accepted.
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.
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.
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.
Inhibits counter operation when gate input is ON.
Outputs made according to designated output mode when corresponding preset is reached.
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.
