Fault handling
When faults are detected on or in the device they are indicated on the
display by an appropriate message. If a reset of the device is necessary
due to the fault, at first the alarm and the associated diagnostic message
have to be acknowledged. Then, the left key has to be pressed for approx.
3 sec. to initiate a reset of the device.
Last status:
E2: 100Hz, E3: 100Hz

If a system failure is detected again after restart the device must be replaced
and sent back to manufacturer.
Maintenance and repairs
- The device contains no parts that require maintenance.
- In case of failure, do not open the device but send it to manufacturer
for repair.
