15 Troubleshooting
15.1 General
The troubleshooting section is used to trace errors in the machine to a defective component or unit.
There is a memory in the control system that will save the selected program for 10 minutes in the case of power fail-
ure. The machine will restart in pause mode if the power is turned on again within this time. For very short power fail-
ure (less than 10 seconds) the machine will restart automatically.
Before resetting any error code, always verify and correct the root cause why the error is trigged.
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 approxi-
mately 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.
