MODEL 355 TROUBLESHOOTING GUIDE
WARNING
ENSURE THAT THE POWER LED ON THE FREQUENCY INVERTER IS FULLY EXTINGUISED
WHENEVER DE-ENERGIZING CONTROL PANEL TO PERFORM ANY ELECTRICAL WORK
(WAIT AT LEAST 30 SECONDS). THIS WILL INDICATE THAT THE HIGH VOLTAGE
CAPACITORS HAVE BEEN FULLY DRAINED. FAILURE TO WAIT MAY RESULT IN
ELECTRICAL SHOCK.
The POWER and RUN green LED’s on the PLC must be on. If not, check for 120V power to terminals
L&N. If no power is present, de-energize control panel and check main disconnect and all control panel
fuses. The POWER LED on the frequency inverter must also be on. At least one input LED on the PLC
should be on. If not, ensure the EMERGENCY STOP button is pulled out. If no inputs turn on, check
for missing jumpers and/or switch wiring in series with the EMERGENCY STOP button; see drawing
#AF35.
Whenever power has been removed to the control panel, the door will go through a setup routine
to reset the door limits. It will open at jog speed until the home proximity switch (open limit) has
been reached. It will then time out and continue to operate at normal speed.
