AEMT TIME MARK 2732 Manuale utente
DESCRIPTION
The Model 2732 Single-Phase Current Monitor is
designed to continuously monitor single-phase AC current.
It consists of a solid-state sensing circuit driving an internal
electromechanical relay. The Model 2732 has two
operating modes; over-current sensing or under-current
sensing. The operating mode is selected by means of a
slide switch on the monitor.
When operating voltage is applied, and the current level is
correct according to the operating mode, the relay will
energize. A fault condition will cause the OVER/UNDER
LED on the monitor to illuminate, and the trip delay will
begin. If correct current is restored, the relay remains
energized. If current is not restored during the delay
period, the relay will de-energize and the red TRIP
indicator will illuminate.
The Model 2732 has three reset configurations: automatic,
manual (add jumper), or manual remote (add NC switch).
The standard model, as provided, will reset automatically.

INSTALLATION
Connect the control wiring to the terminals with the contact
markings (refer to the diagram on the unit). Apply power.
For manual reset, a jumper connection is added on the reset
terminals and the reset button on the top of the monitor is
used.
For remote reset, a remote normally-closed button can be
added (both manual reset buttons can be used in this
configuration).
ADJUSTMENT
Set the time delay to the required amount of delay. If the
desired trip level is known, set the trip adjustment to that point.
A slight adjustment up or down may be necessary to allow for
tolerance variations.
Usually a trip is desired only if the current changes from the
present nominal. For calibration, turn the TRIP DELAY
clockwise to the maximum delay.
Turn the TRIP LEVEL slowly up (or down) until the yellow
TRIP indicator comes on. Turn the adjustment back until the
LED just goes out (if the manual reset is used, press and hold
the reset button during this step).
Reset the time delay to the previous setting.
TROUBLESHOOTING
Should the Model 2732 Single Phase Current Monitor fail to
operate, check all connections. Verify that power is present,
and check all fuses. Should problems persist, contact the
factory at 800-862-2875 for assistance.
