Universal Motor Controller
UMC100-FBP
Technical Description
FieldBusPlug / Issue: 03.2012
Function Overview
Protection Function When active Available Op-
tions:
Warning/Trip/
Off/Other
Automatic
Fault Reset
Possible
Overvoltage: The highest value of the
three phases is above a given thresh-
old. The warning - and trip thresholds
as well as the according delays can be
set.
Motor running
Motor stopped
Not in test position
Trip, Warning, Off -
Undervoltage: The lowest value of the
three phases is below a given thresh-
old. The warning - and trip thresholds
as well as the according delays can be
set.
Motor running
Motor stopped
Not in test position
Warning -
Voltage dip: Low voltage situation
which requires and autonomous load
sheeding handling should take place in
the UMC.
After motor start
Not in test position
Reaction de-
pends on dip
duration.
-
Phase loss: In opposite to the current
based phase loss protection function
this function detects a missing phase
also in the case the motor is stopped.
A warning / trip can be signalled before
the motor is actually started i.e. to
detect a blown fuse.
Motor running
Motor stopped
Not in test position
Trip, Warning, Off Yes, see pa-
rameter 'Fault
auto reset'
Voltage imbalance: This function can
be used to detect smaller voltage im-
balances between the phases. Warning
- and trip thresholds as well as warning
- and trip delays can be set.
Motor running
Motor stopped
Not in test position
Trip, Warning, Off -
Total harmonic distortion: This function
measures harmonic distortions in the
connected mains.
Motor running
Motor stopped
Not in test position
Warning -
Overload: The active power drawn
by the motor is too high. The warn-
ing - and trip thresholds as well as the
according delays can be set.
After load start
Not in test position
Trip, Warning, Off -
Underload: The active power drawn by
the motor is too low. The warning - and
trip thresholds as well as the according
delays can be set.
After load start
Not in test position
Trip, Warning, Off -
Cos phi: A measure of the phase angle
between voltage and current. The
warning - and trip thresholds as well as
the according delays can be set.
After load start
Not in test position
Trip, Warning, Off -
