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.
