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
L E D 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.
