SECTION 12: Motor Protective Devices - 50/60 Hz

12.3 Mounting And Installation

Mount the Pentek Motor Protector in a convenient
®
location in or near the motor control panel. If the location
is wet or dusty, then the Pentek Motor Protector should
be mounted in a NEMA 3R, 4, or 12 enclosure.

12.4 Wiring Connections

1. Connect one line from the fused disconnect to the
Motor protector's "L1 IN" terminal. Run a wire from
the "L1 OUT" terminal to the other in-line controls
such as a pressure or float switch. See Figure 10-1.
2. Connect the other line from the fused disconnect to
Motor Protector "L2 IN" terminal. Run a wire from the
"L2 OUT" terminal to the other in-line controls such
as pressure or float switches. See Figure 12-1.
NOTICE: The Motor Protector may not detect a dead head
(blocked pipe) condition on applications where the pump
is undersized for a given motor or flow restrictors are
used on high stage pumps or low yield wells.

Calibration/Settings
NOTICE: Calibrate the Motor Protector during normal
pumping conditions.
1. Turn the RESTART DELAY / CALIBRATION adjustment
fully counter-clockwise to the "CAL." position.
2. Apply power to the Motor Protector. The pump motor
should be running at this point.
3. The Motor Protector is being calibrated when the
CAL. LIGHT turns on (approximately 5 seconds).
Within 10 seconds, proceed to step 4.
4. Set the RESTART DELAY / CALIBRATION adjustment
to the desired Restart Delay (Dry Well Recovery Time).
If you leave the RESTART DELAY / CALIBRATION
adjustment in the "CAL." position, the unit will trip
off and stay off. Turn the adjustment out of the "CAL."
position to start the pump.

Manual Reset Mode: If the RESTART DELAY /
CALIBRATION adjustment is set to "RESET", the Motor
protector is in Manual Reset mode. After the Motor
Protector shuts down due to a voltage or load problem,
the RESTART DELAY / CALIBRATION adjustment must be
rotated out of the "RESET" position to restart the pump.
NOTICE: Any restart delay can be by-passed by rotating
the RESTART DELAY / CALIBRATION adjustment to
the "RESET" position and back to the desired Restart
Delay setting.
Rapid Cycling Protection: Rapid cycling is defined as
more than four restarts in a 60 second period. The Motor
Protector will lockout upon detecting a rapid cycling
condition until power is removed and re-applied to the
L1 IN and L2 IN terminals. See Diagnostics Table for
instructions to diagnose a rapid cycling fault.
