MULTI-FUNCTION SYSTEM DISPLAY

When the MODE SELECT switch is in the RUN position, the display will show either L1-
L2 Voltage or L2 Current (B). To select t h e displayed parameter, adjust the DISPLAY/
PROGRAM dial to the desired position as shown on its label.
The multi-function display also shows system faults. Any time the MODE SELECT switch is in
the RUN position, the RESET/PROGRAM button may be pushed to view the last fault that
occurred. The table below shows the possible messages.

PROGRAMMING

1. Select the feature to program by rotating the MODE SELECT dial to the desired position. The
MULT setting must be programmed before programming any of the current settings to
ensure proper display of actual current setpoints. Therefore SymCom recommends
programming the LV setting first, then moving clockwise through the positions to complete
the process.
2. Push and hold the RESET/PROGRAM button.
3. Rotate the DISPLAY/PROGRAM dial to the desired setting of the feature as shown on the
display.
4. Release the RESET/PROGRAM button. The Model 77C is programmed when the button is
released.
NOTE: If a setting jumps back to its original number when the button is released, the tamper
guard is set. Refer to the TAMPER GUARD section (page 11) to unlock the setpoints.
5. Repeat steps 1-4 until all features are programmed.
