To display the active program, depress .
To change programs, with the unit in the Program mode, depress

NOTE: Program 0 is the first program. If 10 programs were previously selected using Code 770,
there will be programs 0-9.

Programming New Setpoints
A)
Unit must be in the Program mode.
B)
Select a limit switch circuit for programming. Depress .
The circuit number selected cannot exceed the number of output relays specified earlier using
CIR# 177. See Section 3.5: Selecting Number of Outputs.
C)
Depress . The will set the selected relay turn-on
point.
D)
Depress . . This will set the selected relay turnoff
point.
1)
On units where time-based circuits have been selected, the will be the
time interval that the relay will be active once the ON setpoint has been reached.
E)
Multiple ON and OFF setpoints can be programmed on each circuit. All decimal points will
flash when more than one setpoint exists on the selected circuit.
F)
An LS (Limit Switch) may not have the same value for both the ON point and the OFF point.
If a value is entered that is already a setpoint for that LS, only the new one will be used. For
example: If LS1 had an ON point at 100 and an OFF point of 100 was entered, the ON point
at 100 would be deleted, and the OFF point would then take its place. Assuming that these
were the only setpoints, the output would turn ON at 0 and OFF at 100.
The programmable limits are programmed based on dwell on and dwell off locations. The dwell
on typically represents the location at which a selected limit turns on and the dwell off represents the
location at which the limit turns off. The position locations for the dwell on and dwell off are based
