94 2012-12-01/00561071 [SCR Power Controller TYA201]
Attention!
High temperature Device temperature is higher than 100 °C
(excess temperature) - Ensure adequate ventilation or
provide for additional cooling
- Reduce load current
- Use power controller with high-
er maximum load current
Limiting active
high temperature Device temperature is higher than 105 °C .
Device is too hot, output level is reduced!
(limited power due to excess temperature) - Ensure adequate ventilation or
provide for additional cooling
- Reduce load current
- Use power controller with high-
er 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 device
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 device
type
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 3.3.6 "Master-slave
three-phase current economy
circuit for resistive loads in star,
delta connection, or transformer
loads (resistive-inductive)"
Master-slave
incorrectly wired. Wiring fault has been detected
Rotary field detec-
tion
failed Rotary field detection not possible - Check connection
v Chapter 3.3 "Connection dia-
gram"
- Eliminate line disturbances
Wire break
Current input Input current too small for the set measur-
ing range. - Check wiring for wire breaks and
reverse polarity.
- Check upstream devices (con-
trollers)
Wire break
Voltage input Input voltage too small for the set measur-
ing range. - Check wiring for wire breaks and
reverse polarity.
- Check upstream devices (con-
trollers)
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 Is the patch cable plug connected cor-
rectly?
