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 error is
reported via error LEDs on the front panel of the amplifier module. Press the
SDN
Reset
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 send the device to the manufacturer after
consultation.
