Troubleshooting
General information on troubleshooting
The troubleshooting section is used to trace errors in the machine to a
defective component or unit.
There is a memory in the program unit that will save the selected program
for approx. 3-5 minutes in the case of power cuts.
The machine will restart automatically if the power is turned on again
within this time.
Safety regulations
Troubleshooting may only be carried out by authorised personnel.
Take care during all work on the machine while the power is on.
DANGER
Take care when measuring the motor control system since all com-
ponents have a potential difference of approximately 300V in relation
to protective earth and neutral.
The components will contain dangerous voltages when the green
LED on the motor control board is on.
The motor control system will remain live for 30-60 seconds after
cutting the power to the machine and the motor has stopped run-
ning.
Measurements
For information on measuring points, components and voltages, please
refer to the relevant wiring diagram for the machine in question.
