Remedial action
• Check the mains voltage
If the mains voltage is OK,
replace the control
• Check the mains voltage
If nominal voltage is
continuously exceeded,
stabilize it or use a generator
• Check the mains voltage
• Stabilize the mains voltage
• Use generator
• Disconnect 37-pin plug
If the error is not corrected:
Replace the control
• Test inputs and outputs for
24 V short circuit
• One or several magnets
defective
• Connect the pedal
• Switch off the control, wait until
the LEDs are off and then
switch on again
• Switch off the control, wait until
the LEDs are off, check
connection for machine ID, and
