PROGRAMMING
1. Select the feature to program by
rotating the “MODE SELECT” switch
to the desired position. The “MULT”
setting must be programmed before
any of the current settings to ensure
proper display of actual current
setpoints. Therefore, SymCom
recommends programming the “LV”
setting first, then move clockwise
through the postions to complete the
process.
2. Push and hold the RESET / PROGRAM button.
3. Rotate the DISPLAY / PROGRAM adjustment to the desired setting of the
feature as shown in the LED display.
4. Release the RESET / PROGRAM button. The unit is programmed when the
button is released.
5. Continue steps 1-4 until all features are programmed.
NOTE:
Some “MODE SELECT” positions are dual function such as the
“#RU / ADDR” position. When the “MODE SELECT” switch is pointed
at “#RU / ADDR,” you may view and program “#RU” and “ADDR.” To
view the two settings rotate the “DISPLAY / PROGRAM” adjustment
across its entire range. You will see the “#RU” setting when the
“DISPLAY / PROGRAM” adjustment is between approximately 7 O’Clock
and 11 O’Clock. You will see the “ADDR” setting
when the “DISPLAY/PROGRAM”adjustment is between approximately
11 O’Clock and 5 O’Clock. To program “#RU” or “ADDR,” follow the
programming instructions above. The “#RU” setting will only be
programmed when the “DISPLAY / PROGRAM” adjustment is between
approximately 7 O’Clock and 11 O’Clock. Likewise, the “ADDR” setting
will only be programmed when the “DISPLAY/PROGRAM”adjustment is
between approximately 11 O’Clock and 5 O’Clock. “ADDR” settings will
be an “A” followed by a number between 1 and 99.

Operation
The relay operation of SymCom’s overload relay is a fail safe design. This
means when everything is within the limits programmed into the unit, the relay
will energize; the normally open (NO) contact will close and the normally closed
(NC) contact will open. Once the unit has been wired and programmed, the unit
is ready to operate. Turn the mode select to the “RUN” position. The display will
show “RUN” alternating with some number (the numbers displayed will be the
number corresponding to where the “DISPLAY/PROGRAM” knob is pointed). It
will do this for the amount of time programmed into “RD1”. After this time has
expired, the relay will energize (normally open will close and normally closed
contact will open). If something else is in the display, see the troubleshooting
section for more information. If the mode select is taken out of the “RUN”
position, the units relay will de-energize.
