System Troubleshooting
The chart below will be helpful when attempting to isolate problems which may be encountered in the
control system. It can also prove useful when problems are encountered during initial start-up. By no
means does this represent every possible problem which can occur, but highlights the most common
problems that are typically encountered.
Probable Cause Suggested Solution
No output on either Channel
during power up
Fuse keeps blowing
Channel 2 activates on power up
Output channels do not switch,
inputs do not switch
Magnets do not appear to
have sufficient torque
• Improper wiring – check wiring and correct
• No power available – check AC input power
• Blown fuse – check input fuse and replace
• Wires not inserted into TB’s – correct and secure
• Incorrect wiring – check wiring and replace fuse
• Incorrect AC line voltage applied – correct line voltage
and replace fuse
• Fuse size too small (rating) – check fuse ratings and
replace with correct value
• Incorrect magnet voltage – check coil ratings of
magnets and replace with correct magnets if necessary
• Shorted magnet coil – check magnet coil resistance for
proper valve and replace if necessary
• Incorrectly wired – check control wiring and rewire if
necessary
• Input switching faulty – check input switching device
and replace if necessary
• Incorrect input logic from switching device – verify and
change as necessary
• Incorrect wiring – check wiring and correct if necessary
• No AC input – check for AC input voltage to control
and correct if necessary
• Incorrect or faulty switching devices – check for proper
operation and outputs and replace if necessary
• AC input fuse blown – check for blown fuse and
replace if necessary
• Control is faulty – replace control
• Incorrectly sized magnets – verify sizing and selection
for application and resize if necessary
• Full output voltage not applied to magnets – check for
faulty control or proper magnet voltages selected for
control voltage (90v magnet on 24v control)
• AC input voltage below minimum – check for proper
AC voltage and correct if necessary
