setpoint program. The program is placed in hold at the beginning. The mode will be as
configured under "PWR UP" in the "CONTROL" group.
Digital Input (remote switch) operation
Program can be placed in RUN, HOLD, RERUN, or BEGIN state through a remote dry
contact connected to optional digital input terminals, as follows:
RUN—contact closure places Program in RUN state, OR
HOLD—contact closure places Program in HOLD state
RERUN—contact closure allows the Setpoint Programmer to be reset to the initial
segment of its current cycle, unit stays in previous mode.
Opening the contact will cause the Controller to revert to its original state.
BEGIN— Contact closure resets the SP Program back to the beginning of the first
segment in the program and puts the program in the HOLD mode. Program cycle number
is not affected. Reopening the switch has no effect.
Opening the contact will cause the Controller to revert to its original state.
