Technical Description
FieldBusPlug / Issue: 03.2012
Indicator Code Source / Root Cause Possible Cause / Suggested Ac-
tion
Phase loss 1 Supply side
Load side
Contactors
At least one phase current is below
the phase loss threshold
Check for blown fuse
Check for loose contacts
Check contact wear
Phase imbalance 2 Supply side
Load side
Contactors
The current in one phase is below
the adjusted threshold.
Check supply side
Check for loose contacts
Check contact wear
Locked Rotor 3 Load Side The rotor is locked. Load too heavy
for motor.
Thermal model reached
warning level
4 Load Side Thermal model reached warning
level. If overload condition remains
a trip soon follows.
Check motor load condition
Check for mechanical problems
PTC overtemperature 5 Load side
Environment
PTC element indicated that motor
temperature is too high
Check motor environment and load
conditions
PTC wiring problem 6 Summary message. See
detailed messages for
more information.
See codes 83/84
Check-back error 7 Summary message. See
detailed messages for
more information.
See codes 80...82
Motor current below low
current trip threshold
8 Process
Load side
Load side mechanics
Motor current is below user-defined
threshold e.g. motor running idle,
dry running pump, conveyer belt
broken ...
Check motor load and motor / pro-
cess conditions. Wait until cooling
time is over.
Motor current below low
current warning threshold
9 Process
Load side
Load side mechanics
Motor current is below user-defined
threshold e.g. motor running idle,
dry running pump, conveyer belt
broken ...
Check motor load and motor / pro-
cess conditions
Motor current above high
current trip threshold
10 Load side Motor current above threshold
caused e.g. by jammed equipment
Check process conditions (remove
blocking cause). Wait until cooling
time is over.
Motor current above high
current warning threshold
11 Load side Motor current above user-defined
threshold.
Check motor load and motor / pro-
cess conditions.
