10.6 Fault indications

Possible cause
Fault in software.
PSE parameter fault.
Fault
By-pass relays closed after transport,
(PSE18...PSE170 only).
Fault
The by-pass contactor's/relays are not
opening.
Thyristors short circuit.
Power loss on control supply circuit.
By-pass relays/contactor's open or by-
pass relays/contactor's do not close.
Fault
Thyristors overheated. If the fault remains
after reset, the heat sink temperature is too
high.
Fault
Softstarters Type PSE18...PSE370 Installation and commissioning manual 1SFC132057M0201
Solution
• Disconnect and reconnect the control
supply voltage (U s ) and make a re-
start. See chapter 5.2.4.
• If same fault remains, contact your
ABB Sales Office.
• Check parameter PSE and select cor-
rect setting corresponding to the type
of PSE Softstarter. See chapter 7.7.2.
• 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.
• Check and replace relay. Contact your
ABB Sales Office for replacement kit.
• Check and replace thyristor. Contact
your ABB Sales Office for replacement
kit.
• Check control supply voltage
• Check and replace by-pass relay/con-
tactor. Contact your ABB Sales Office
for replacement kit.
• 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 C (104 F). See chapter 3.6.
o o
• Check that the mounting angle is not
more than 30 . See chapter 4.2.4.
o
• Check that PSE Softstarter not is too
small for the number of starts and
stops performed each hour.
