92 2012-12-31/00561073 [SCR power switch TYA202]
Limiting active
high temperature Device temperature is higher than 105 °C.
Device is too hot, power is reduced!
(limited power due to excess temperature) - Ensure adequate ventilation
- Reduce load current
- Use power controller with
higher maximum load current
Supply voltage is
too low Supply voltage is not within specified toler-
ance range
v Chapter 10.1 "Voltage supply, load
current"
Check nominal voltage of the de-
vice type
v Chapter 1.3 "Order details"
Supply voltage is
too high Supply voltage is not within specified toler-
ance range
Chapter 10.1 "Voltage supply, load cur-
rent"
Check nominal voltage of the de-
vice type
v Chapter 1.3 "Order details"
Temporary
drop in supply Dangerous temporary equal proportion for
transformer loads has been detected.
v Chapter 5.1.5 "Monitoring"
Ensure stable mains supply.
Master-slave
rotary field error Counterclockwise rotary field has been de-
tected
v Chapter 3.3.1 "Rotary cur-
rent economic circuit mas-
ter-slave for resistive loads
in star or delta connection
or transformer loads (resis-
tive-inductive)"
Master-slave
incorrectly wired. Wiring fault has been detected
Rotary field detection
failed Rotary field detection not possible - Check connection
v Chapter 3.3 "Connection
diagram"
- Eliminate line disturbances
Wire break
Current input Input current for the set measuring range out-
side the valid range. - Check wiring for wire breaks
and reverse polarity.
- Check upstream devices
(controllers)
Wire break
Voltage input Input current for the set measuring range out-
side the valid range. - Check wiring for wire breaks
and reverse polarity.
- Check upstream devices
(controllers)
Malfunction
Bus error No connection to the Profibus master Check wiring and master device
(PLC).
Master-slave
Error in comm. Error in the data transfer between master and
slave Check data connection of patch
cable
Data cable
faulty Communication between master and slave
interrupted. Check the patch cable and re-
place, if necessary
Synchronization
failed Slave device switched off or communication
between master and slave interrupted Check data connection of patch
cable or voltage supply
