6 Operation / Maintenance
6.1
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 error is
reported via error LEDs on the front panel of the amplifier module. Press the SDN Reset 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.
Symptom
Device will not turn on; Power LED
will not light up
HV off palm button will not light up
Output signal is distorted
Amplifier switches off, the
OVERLOAD indicator lights up
Amplifier switches off, the
OVERTEMP indicator lights up
6.2
Maintenance
Depending on the cleanliness of the ambient air dust may accumulate within the unit possibly blocking
the airflow. In that case the accumulated dust has to be removed by blowing out the unit cautiously.
The manufacturer specified lifetime of the fans is >50000h. After about 6 years of continuous operation
the fans might be replaced.
Type: Papst 8314H (HAR42-4).
Caution: disconnect the unit from the power supply before removing any modules or opening any
covers.
Further regular maintenance is not required.
6.3
Cleaning
If necessary, wipe the device with a slightly damp cloth. Do not use abrasive detergents or solvents.

Possible causes
- No supply voltage present
- Fuses F1, F2 in the IEC inlet defective
- HV off palm button is in off position (pushed in)
- Interlock circuit is open
- Load capacitance too large for the desired slew rate
(see section 3.6 for load conditions)
- Dynamic load current exceeded (see section 3.6 for load
conditions)
- Static load current exceeded (see section 3.6 for load
conditions)
- Poor ventilation
- Total load too large (see section 3.6 for load conditions)
