By-pass relays closed after transport,
(PSE18...PSE170 only).
•
Switch off operational voltage and
control supply voltage. Switch on volt-
age in correct succession.
1. Control supply voltage on terminals
1 and 2. See chapter 5.2.4.
2. Wait 4 seconds, and then switching
on operational voltage on terminals
L1, L2 and L3. See chapter 5.2.3.
The by-pass contactor’s/relays are not
opening.
•
Check and replace relay. Contact your
ABB Sales Office for replacement kit.
Thyristors short circuit.

Check and replace thyristor. Contact
your ABB Sales Office for replacement
kit.

Fault
Thyristors overheated. If the fault remains
after reset, the heat sink temperature is too
high.
•
Check that the fans are working in a
proper way. See chapter 9.1.
•
Check that the cooling airways are
free from dirt and dust. See chapter
9.1.
•
Check that the ambient temperature
is not too high. Derating is required
above 40
o
C (104
o
F). See chapter 3.6.
•
Check that the mounting angle is not
more than 30
o
. See chapter 4.2.4.
•
Check that PSE Softstarter not is too
small for the number of starts and
stops performed each hour.
