Troubleshooting

General information about troubleshooting

The troubleshooting section is used to pinpoint a fault on the machine to a
specific defective component or unit.
If the power supply is interrupted, the programme memory will keep the
select programme in its memory for approx. -5 minutes.
Within this time period, the machine automatically restarts after the power
interruption.

Precautions

Only authorized personnel is allowed to troubleshoot the machine.
Prior to commencing troubleshooting, pay close attention to the
precautions in section 1.
If the power is on, be very careful when working on the the machine.

DANGER

Be very careful when measuring the motor controller since all com-

ponents have a potential difference of about 300 V compared to

Ground and Neutral.

When the green LED is lit, all components are powered with dange-

rous voltage.

When the power supply to the machine is interrupted and the motor

has stopped, the motor controller will does lose power until after

10-30 seconds.

Measurements

For information about measurement points, components and voltages,
please refer to the wiring diagrams for the machine.
