Fault Rectification The action required for the rectification of faults is shown in the following table
Method of Operation The functions of the transfer control device are shown in the following diagram:
Technical Data Degree of Protection IP40
Weight Ca. 10 kg
Voltage variation 0 to 0.55
Ue
Frequency variation Not monitored
Contact transfer time 200 ms + T1, adjustable (1.5 s to 30 s)
+ emergency supply run-up time
Transfer time 200 ms
Return transfer time 200 ms + T2, adjustable ( 5 s to 100 s)
Break time 65 ms

Storage temperature -50 to +80°C
Fault Cause Action
The yellow "TRIPPED" lamp is lit One of the two circuit-breakers
has tripped as a result of
overcurrent.
Press RESET on the relevant circuit-breaker
after rectification of the fault. Press RESET on
the transfer control device (for approx. 1 s)
until the lamp goes off.
The "MAIN READY" lamp or "GEN.
READY" lamp is not lit even though
mains supply or emergency supply is
present
A circuit-breaker (QN1 or QG1)
in the transfer control device
has tripped.
Switch the relevant circuit-breaker on after
checking and correcting any fault.
