TROUBLESHOOTING
Green LED lights are illuminated on the PLC when in opera-
tion. The POWER, OK & RUN lights indicate that 24VDC
power is available to the PLC and that is functioning properly.
If the RUN light is out, the operational program of the PLC
may have been corrupted or lost. Temporary power surges may
have occurred. Secure all power to the machine , wait for 30
seconds and restore power. Verify that the Green light is illumi-
nated to the 24vdc power supply immediately to the left of the
PLC. If the RUN light is still off, replace the PLC.
Refer to the illustration below for the designation of each LED.
Inputs correspond to the connections behind the top flip up
panel of the PLC and are marked I1 thru I8. Outputs correspond
to the connections behind the bottom flip up panel of the PLC
and are marked Q1 thru Q8.
Note: All outputs are fused. Q1 & Q2 outputs utilize 1.0 Amp
fuses and Q3-Q8 utilize .75 Amp fuses.
