1-1 Description
EntelliGuard

TU Test Kit is a lightweight, portable test
instrument designed for field-testing of EntelliGuard TU Trip
Units. The Test Kit includes the following features:
• Operation from a 100-240VAC 50/60 Hz Universal plug supply
or two 9-volt alkaline batteries (batteries not supplied).
• Provides power to the trip unit for viewing and setting set-
points with no load on the breaker
• Verification of metering (phase simulation)
• Trip test
• Temporarily disable the Ground Fault feature during single
phase breaker testing
1-2 Summary of Operation
The functions of the various switches and LEDs on the panel
(see front cover) are as follows:
Power Switch
Pressing this button will power-up the trip unit. The green
Power LED will indicate that power has been provided to the
trip unit. A red Battery Low LED indicates that the batteries
in the test kit should be replaced.
Trip Breaker Switch
Pressing this button will cause the breaker to trip. The switch
has an associated red LED that indicates the state of the
switch. If the LED is illuminated, then switch is ON and firing
the flux shifter to trip the breaker.
Disable Ground Fault
Pressing this button will cause the trip unit GF protection to
be temporarily disabled. To enable the GF, the switch and
associated red LED must be turned off. The GF switch has
an associated red LED that indicates the state of the switch
(GF disabled when red LED illuminated).
WARNING: When using EntelliGuard Digital Test Kit to defeat
Ground Fault function of EntelliGuard Trip Units, the ground fault
protection of the trip unit will not be active. Power to the breaker
should be removed prior to using this feature. Before applying
load to the breaker, ensure that the Disable GF LED is OFF or the
Test Kit is disconnected from the trip unit.
Failure to follow this procedure can result in deactivation of the
Trip Unit GF protection.
