40 • TROUBLE SHOOTING
________________________________________________________________________________________________
Fault Massage Cause and trouble shooting
SHORTED SCR Trips/Alarms when internal Thyristor is shorted.
Consult factory.
WRONG CONCT
TYPE
Trips/Alarms when TPS microprocessor sees a different connection type
then the one programmed.
Check actual connection type and programmed connection type.
For more information on programming CONNECTION TYPE refer to
section
7.7.1 on page 28.
HEATSINK OVER T. Trips/Alarms when TPS thyristor heat sinks are over heated.
Stop the unit and check for overload conditions and check right operation
of fans.
EXTERNAL FAULT Trips/Alarms when TPS gets an external input indicating a fault.
COMM PORT
FAILED
Trips/Alarms when communication error occurs.
Check wiring, Reset the TPS and try again. If this failure happands again
consult factory.
INTERNAL
FAILURE
Trips/Alarms when an internal failure is detected by the microprocessor.
Get factory defaults and reprogram the TPS.
For more information on getting factory defaults and reprogramming the
TPS refer to section
7.5.1 on page 24.
No control via
Analog Input
When the TPS is programmed to get its analog input via communication,
wired analog inputs (Terminals 16, 17 and 20) are not operative.
Refer to COMM. PARAMETERS SETTINGS – SER. LINK CONTROL.
For more information on setting the right parameters for the TPS operation
regarding SERIAL LINK CONTROL, refer to section
7.7.6on page 36.
Output
voltage/current does
not go to zero even
though analog input
is lowest.
Output voltage/current does not go to zero even though analog input is
lowest.
When load is connected in WYE NEUTRAL NOT CONNECTED or in LINE
DELTA (both connections are without a neutral point) and TPS is in
PHASE CONTROL it is impossible to go to zero output.
Minimum possible firing for such case gives 10-20% of output voltage. This
is since in this case the firing of each phase depends on the three phases
mains and we cannot control each phase voltage down to zero.
In this case, zero input in analog input causes the minimum possible
voltage to appear in the output. Then, upon increasing the analog input
voltage, output voltage/current is monotonically increased.
