Fault finding guidelines
Advice!
All faults that may be corrected by the operator are indicated by the HMI. In the event of
a fault occurring that cannot be cleared by the operator, please refer to GEW or your local agent
for service.
Warning!
There are no user serviceable parts inside the e-Brick; do not remove covers under
any circumstances. Please note that if factory security seals are broken, the warranty is void.
With the exception of a communication problem, should any fault occur, the alarm bell flashes and
the fault is displayed on the left hand side of the screen. In the event of a communication failure, a
text message "Communication failure with lamp x, please deselect" will be displayed. The system
will still run with a communication failure, however the operator must deselect the faulty lamp on
the HMI. The 'fault' screen (Figure ), shows the faults that have occurred for each lamp.
