GE Industrial Solutions ProTrip Trip Units Target Module User Manual
Protrip™ trip unit target module, Protrip™ conversion kits

Introduction
ProTrip™ Trip Units are equipped with a Target Module.
This unit indicates whether a breaker trip was caused by a
short circuit, an overload, or a ground fault. The Target
Module is shown in Figure 1. The catalog number is
TARGET02P.
Note that the Target Modules do not provide the ground-
fault protection function. Ground-fault protection is
provided by the Rating Plug.

Functions
The front of the Target Module contains two push buttons
and five LEDs. The following functions are provided by
the Target Module.
Trip Targets
To determine the condition causing a breaker trip, press
the
VIEW
button. One of the three target LEDs will light, as
follows:
SC
– Short circuit (instantaneous or short-time trip).
OVL
– Overload (long-time trip).
GF
– Ground.
The
RESET
button clears the trip target indication.
Long-Time Pickup Status
Whenever the circuit breaker is carrying at least 95% of
the long-time pickup current (C), the
LTPU Status
LED
begins to blink. Above 100% of the long-time pickup
current, the LED is lit continuously, indicating an
imminent overload trip.
Battery Test
If the breaker has not tripped or if the trip target has been
cleared, pressing the
VIEW
button performs a battery test.
The
BAT
LED will light if the batteries are okay. If the
BAT
LED is dim or does not light, replace the batteries as
described below. Note that the only function of the Target
Module batteries is to power the LEDs; they have no effect
on Trip Unit operation and are not required to store
targets for any protection functions.
Health Monitor
The Trip Unit can be tested for proper functioning if the
Trip Unit is powered by one of the following sources:
• A Test Kit (catalog number TVRMS2) is plugged
into the jack on the front of the Rating Plug.
• The breaker is carrying a load current of at least 20%
of its current sensor rating.
• External +24 Vdc control power, if connected.
Press and hold the
VIEW
button for at least five seconds. If
the Trip Unit is operating properly, the
LTPU
LED will
blink slowly. Note that if the Trip Unit is not powered by
one of the above sources, this test will not give a true
indication of Trip Unit functioning.
Installation
To install a Target Module in a ProTrip Trip Unit,
remove the existing module by following the removal
instructions below. Hold the Target Module between the
thumb and forefinger, then push it into the Trip Unit.
Proper engagement is verified by a click.
