Check for Tripped Circuits

with its respective sensor. Check the Status Light Panel,. If all lights are observed,
there are no overloads or emergency stops tripped. See”
“below, for more information.
Note:
Most electrical problems are related to mechanical malfunction (e.g., stuck motors, jammed
chain, blocked photo sensors etc.)

If a solenoid valve is suspected, and not cleared in the air checks section (see), it can be electri-
cally jumped to check operation.
Troubleshooting with the Status Light Panel

system is in proper working order. The lights turn on in a sequence and will stop at the point
where a fault is first detected.
