Troubleshooting
19.3 Unit locks up and/or does not discharge
completely
The device features an emergency button to safely discharge the transformer in case of any
problem. This works independent of the software!
The user MUST always observe the red LEDs on the front panel (they work even if there is
no mains supply!)
The user MUST only disconnect the clamps, if there is NO red LED illuminated!
A charged system is always very dangerous condition!
The User MUST NEVER disconnect any clamp from the Transformer as long as there is a
current flowing in the Transformer!
Follow this safe discharge procedure in case of lock up:
1. Press emergency button
2. Wait for the red LED to turn OFF. This can take up to several minutes.
3. If the red LED did not turn off after 10 minutes, the user MUST switch off the device and disconnect the
mains supply.
4. The user MUST continue to wait for the red LED to turn OFF. Even if it takes hours (normally it can only
take up to some minutes).
5. Device could be rebooted now (not necessarily).
6. The user MUST only disconnect the Clamps from the transformer if the red LED is OFF!
