TIME MARK is a division of
3-Phase Monitor
Detects Phase Loss, Low Voltage
and Phase Reversal
Adjustable Trip and Restart Delays
Automatic or Manual Reset
DPDT Output Contacts
DESCRIPTION
The Model 2652 3-Phase Monitor is designed to
protect motors, pumps, HVAC equipment, air compressors, etc., by sensing phase loss, low voltage or phase
reversal.
With correct power applied, the DPDT output contacts
transfer and drop out when a fault condition or loss of
power occurs. An adjustable trip delay prevents nuisance tripping. The restart delay timer prevents short
cycling, which is primarily used with HVAC and compressor motors.
The DPDT output contacts allow the Model 2652 to be
used in control circuits and alarm circuits. The automatic reset can be converted to a manual reset by
adding a normally closed switch.
Five different voltage versions of the Model 2652 can be
adjusted over a wide operating range. This unit is
housed in an ABS plastic surface-mount case to reduce
space requirements.

READ ALL INSTRUCTIONS BEFORE INSTALLING, OPERATING OR SERVICING THIS DEVICE.
KEEP THIS DATA SHEET FOR FUTURE REFERENCE.
GENERAL SAFETY
POTENTIALLY HAZARDOUS VOLTAGES ARE PRESENT AT THE TERMINALS OF THE MODEL 2652.
ALL ELECTRICAL POWER SHOULD BE REMOVED WHEN CONNECTING OR DISCONNECTING WIRING.
THIS DEVICE SHOULD BE INSTALLED AND SERVICED BY QUALIFIED PERSONNEL.
Installation Instructions
INSTALLATION
Connect the 3-phase power to the terminals marked A,
B, and C.
Connect the control circuit wiring to one set of the
output terminals.
(Optional) Connect the second set of output terminals
to an alarm circuit, or to the control circuit of a second
load.
A standard wiring diagram is shown in the TYPICAL
APPLICATION drawing. The contact markings are
shown in the TRIPPED, or Power-OFF condition.
FOR MANUAL RESET, instead of the built-in automatic
reset, install a normally-closed pushbutton switch
across the terminals marked RESET. The manual reset
leads should be kept as short as possible.
TYPICAL APPLICATION
Shows No Power Applied
ADJUSTMENT
NOTE: When adjusting the Model 2652, you may
want to jumper the control circuit contacts, and
disconnect the alarm contacts connection, to
prevent the unit from cycling the load, during setup.
Turn the VOLTAGE ADJUST, RESET DELAY, and the
TRIP DELAY pots fully counter-clockwise.
Turn the VOLTAGE ADJUST clockwise, until the unit
trips (NORMAL indicator OFF; TRIP indicator ON).
Slowly turn the VOLTAGE ADJUST counter-clockwise
until the unit resets (TRIP indicator OFF).
Set the TRIP DELAY and RESET DELAY to the desired
time settings.
This trip level adjustment will be correct for most
applications.
The TRIP DELAY should help prevent nuisance tripping
due to power fluctuations, or motor start-ups. Should
nuisance tripping still occur, increase the delay time a
little, or turn the VOLTAGE ADJUST slightly farther
counter-clockwise.
