TIME MARK CORPORATION 2652 3-Phase Monitor

MODEL 2652

3-Phase Monitor 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 compres-sors, 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 nui-sance tripping. The restart delay timer prevents short cycling, which is primarily used with HVAC and com-pressor motors.
The DPDT output contacts allow the Model 2652 to be used in control circuits and alarm circuits. The auto-matic 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

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 set-up.

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.
