Note:
The SubMonitor
is not
compatible with variable frequency
drives, electronic phase converters, or
solid state soft starters. These devices
will cause nuisance tripping of the
motor overheat fault, or may cause
damage to SubMonitor components.
Reduced voltage starters may be used
with SubMonitor if they are bypassed
during normal running condition
(Figure 5), and if the starting time does
not exceed 3 seconds.
Power Factor or Surge Capacitor
—
across-the-line capacitors for
either power factor correction or
surge protection may be used with
SubMonitor. If used, these capacitors
must be connected to the power
supply lines before these lines pass
through the SubMonitor sensor coil
windows or motor overheat protection
may be lost.
Other Features
Reset
The receiver will not allow a reset for several minutes after a fault trip,
depending on the programmed reset time and fault mode. This allows time
for the motor to cool before it is restarted after a problem has occurred. Any
Manual Reset causes the motor to restart in exactly one minute.
Operation without the Display Unit
After the
Select Motor
parameters are entered (volts, Hz, and SF Amps),
the base unit of SubMonitor provides full motor protection even when the
Display Unit is disconnected.
When operating with a Base Unit only:
• A “run enable” condition is indicated by a green LED
• A trip condition is indicated by a red Fault LED
• Manual reset is initiated by pressing the Reset Switch
• The Event History is not recorded (total run time is recorded).
