9.1
Troubleshooting
If the device behaves unusual or erratic, please switch off the supply voltage and check the wiring of
the load and that of the control and monitoring signals. Check the connected load and the signal
source. Check the interlock circuit.
During operation various parameters are monitored and analyzed. In case of a fault the condition is
shown via LEDs on the front panel of the amplifier. Press the
SDN RST
push button to reset the error
condition.
Do not attempt to locate any faults within the device. This can be dangerous to life due to the high
voltage used in the device. In such a case, please return the device to the manufacturer after
consultation.
