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 setpoints with less than 15% load on the breaker or if the replaceable Trip Unit Battery needs replacing.
•Verification of metering (phase simulation)
•Ground Fault Testing with Ground Fault Trip Indication
•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 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.

1.2 Summary of Operations, Continued
Ground Fault & Overload
Pressing this button will cause a trip either on the Ground Fault or Overload protection. The switch has a red LED that is ON when the switch is pressed. This feature will store the trip event in the Event log and operate the bell alarm, if available.
1.3 Specifications
The EntelliGuard Digital Test Kit Catalog Number is GTUTK20. It includes the following components:
•Test kit box
•24VDC power supply – CUI Inc., Part Number EMS 240075- P5P-SZ or equivalent.
•Voltage polarity is as follows:
CAUTION: With the Phase Current enabled, the EntelliGuard trip unit will not provide correct protection to the system, which may result in a trip below desired levels. Power should be disconnected from the circuit breaker prior to entering Phase Current Mode.
Ensure that the Phase Current LED is OFF when in normal operation. Failure to follow this procedure can result in improper operation of the system.
Phase Current
By pressing this switch, the EntelliGuard trip unit
will display approximately 100A on each current phase. This can be viewed on the trip unit LCD under METER menu. The switch has a red LED that indicates the state of the switch (LED On when Switch is ON).
