SETTINGS
1.
LOW VOLTAGE ADJUSTMENT:
Rotate the
LOW VOLTAGE ADJ. (VAC)
to the desired low
voltage setting. If any of the three phases drops
below this setting, the MotorSaver
®
will open its
relay contacts after the preset trip delay.
2.
HIGH VOLTAGE ADJUSTMENT:
Rotate the
HIGH VOLTAGE ADJ. (VAC)
to the desired high
voltage setting. If any of the three phases rises
above this setting, the MotorSaver
®
will open its
relay contacts after the selected trip delay.
3.
RESTART DELAY ADJUSTMENT:
Rotate the
RESTART (SEC)
knob to the desired position.
The restart delay is the time between the
MotorSaver
®
seeing acceptable voltage and the
MotorSaver
®
closing its output contacts. For
compressor applications, the restart delay should
be set for the approximate time it takes for the
head pressure to bleed off of the compressor. For
other applications, the restart delay is typically set
between 2 and 10 seconds.
4.
TRIP DELAY ADJUSTMENT:
Rotate the
TRIP DELAY (SEC)
knob to the desired setting. This
adjustment does not affect the trip delay on phasing faults. Typically, the trip delay adjustment
is set between 1 and 5 seconds. In areas where voltage fluctuations are frequent, the trip delay
adjustment may be set greater than 10 seconds.
