Cause
Device temperature is higher than 105 °C.
Device is too hot, output level is reduced!
(Limited power due to excess temperature)
Mains voltage is not within specified toler-
ance range
v Chapter 10.1 "Voltage supply, load
current"
Mains voltage is not within specified toler-
ance range
Chapter 10.1 "Voltage supply, load cur-
rent"
Dangerous temporary equal proportion for
transformer loads has been detected.
v Chapter 5.1.5 "Monitoring"
Counterclockwise rotary field has been de-
tected
Wiring fault has been detected
Rotary field detection not possible
Input current too small for the selected
measuring range.

Remedy
- Ensure adequate ventilation or
provide for additional cooling
- Reduce load current
- Use power controller with high-
er maximum load current
Check nominal voltage of the device
type
v Chapter 1.3 "Order details"
Check nominal voltage of the device
type

Ensure stable mains supply.
v Chapter 3.4.6 "Master-slave 3-
phase current economy circuit
for resistive loads in star/delta
connections, or
loads (resistive-inductive)"
- Check connection
v Chapter 3.3 "Connection dia-
gram"
- Eliminate mains disturbances
- Check wiring for wire breaks and
reverse polarity.
- Check upstream devices (con-
trollers)
- Check wiring for wire breaks and
reverse polarity.
- Check upstream devices (con-
trollers)
Check wiring and master device (PLC).
Is the 1:1 patch cable plug connected
correctly?
Check the 1:1 patch cable and replace,
if necessary
Check plug connection of 1:1 patch
cable or voltage supply
