6.0 Troubleshooting
Interface Not Functioning
Possible Problem Item to Check Remarks
Control voltage fuse blown Check for blown fuses. If the door interlock has shorted out,
it is usually because someone
attempted to open the shutter door
while in Run Mode. Check the
interlock before re-energizing this
circuit. Replace as necessary.
No power to the machine Carefully check the three terminal
blocks on the top of the main
disconnect for line power. Consult with your plant electrician to
determine the source of the power
outage.
PLC Power Supply Blown Check the lights on the PLC located
inside the control box. The Power Supply on the PLC also
powers the Interface, If there is power
to the Drive Inverter and not to the
PLC first check fuses then replace the
Power Supply if needed.
No input voltage Check that the main disconnect
located on the electrical cabinet door
is turned to the “On” position Make sure that the machine is not
being serviced before re-energizing
the machine.
Main fuses blown There are three fuses located in the
main disconnect. With the power off,
check for continuity across each of
these fuses. If a fuse is blown, DO NOT REPLACE
IT until the problem that caused the
fuse to blow has been corrected.
Loose wire or defective
component Turn the main disconnect to the “Off”
position and carefully check and
retighten electrical connections
beginning at the main disconnect. If you are certified to work with high
voltage AC, re-energize the
Disconnect and follow the voltage
paths until you find the problem.
