13 Troubleshooting
13.1 General
The troubleshooting section is used to trace errors in the machine to a defective component or unit.
There is a memory in the CPU that will save the selected program for 10 minutes in the case
of power failure.
The machine will restart in pause mode if the power is turned on again within this time. For very
short power failure (less than 10 seconds) the machine will restart automatically.
Safety regulations
Troubleshooting may only be carried out by authorised personnel.
Take care during all work on the machine while the power is on.
Take care when measuring the motor control system since all components 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 running.
Measurements
For information on measuring points, components and voltages, please refer to the electric
schematic supplied with the machine.
