Remote Control Signals - KYOWA DPM-900 Series Instruction Manual

5-13-1 Remote Control Signals

Control signal input circuit is shown at the right.
Control signals are valid when they are on the "L" (0 V) level. While this level is maintained, functions are
executed.
The balancing function by the remote control is executed only one time in response to a signal shown at
the right.
When executing the CAL addition on and off by the remote control, use the signal in the right.
NOTE
When an external control signal is "H," it is made to be on the level of approximately 5 V by the
internal circuit.
Avoid generating chattering when rising or falling the control signal.
