GENERAL SAFETY PRECAUTIONS HIGH CURRENT This equipment is capable of providing POTENTIALLY LETHAL VOLTAGES and /or SEVERE BURNS! Improper operation or test practices may result in injury or death to the operator or surrounding personnel. The operation of High Voltage test equipment should only be performed by personnel familiar with HIGH VOLTAGE testing and safety procedures.
INTRODUCTION The HC-3 is a portable high current test set built for field and shop use. Designed using the latest technology, the HC-3 combines a variable high current output with appropriate controls and instrumentation for testing thermal, magnetic, and solid-state motor overload relays, molded-case circuit breakers, and ground fault trip devices.
SECTION 1: TECHNICAL SPECIFICATIONS 220-240 Volts, 50 Amps – Delay Circuit Breaker INPUT: 50 Hz or 60 Hz (must be preset) OUTPUT: 0-15 Volts, 0-333 Amps 0-10 Volts, 0-500 Amps 0-5 Volts, 0-1000 Amps OVERLOAD: Short duration overloads are possible on each tap. The test set is capable of up to 5000+ amps, depending on the impedance of the test circuit.
SECTION 2: DEVICE WARNINGS 1. For safe operation, it is important that the unit be plugged into a properly grounded receptacle. 2. This unit is NOT designed for use to test energized circuits. 3. WARNING: Due to leakage current within the solid-state circuitry, it is STRONGLY RECOMMENDED to turn control power off when changing the output leads.
SECTION 3: CONTROLS AND INDICATORS Refer to Figure 2 Refer to Figure 1 Refer to Figure 3 The following is a listing of the controls, switches, and lamps on the control panels and a description of their functions. Refer to Figures 1 through 3 below. HC-3...

CONTROLS AND INDICATORS Figure 2. HC-3 Controls and Indicators 5. HC ON When pressed, this allows current to flow from the unit (provided that the output is shorted as through a closed breaker). If this output current exceeds approximately 9% (5% of 4000A range) of the selected output current range, the output will be maintained when the switch is released.

CONTROLS AND INDICATORS 9. TRIP/RESET This switch serves several purposes. 1) When in CONTACTS mode, the lamp will illuminate to indicate that the non- energized contacts of the test specimen connected to the SENSE INPUTS has changed states. 2) When in CURRENT mode, the lamp will illuminate to indicate that the output current has dropped below the 9% level (5% of 4000A range).

CONTROLS AND INDICATORS 13. MEM/CONT When set to the CONT (continuous) mode, the meter will continuously update to display the output current level. When placed in the MEM (memory) mode, the meter will retain the highest output current level achieved. If the level again exceeds this value, the meter will be updated.
SECTION 4: BASIC APPROACH TO TESTING The HC3 is a continuously variable high current source, the magnitudes of which are dependent on the output tap which is selected. Please refer to the Technical Data and Specifications for the voltage and current ratings of the taps.
SECTION 5: CALIBRATION TIMER The timer is run from a precision programmable oscillator and should never require calibration. CURRENTMETER The calibration of the currentmeter should be checked annually. To do this, place the MEM/CONT switch in the CONT position. Place the range switch in the lowest range. With nothing connected to the output and the CURRENT CONTROL knob in its fully counterclockwise position (zero position), adjust R75 until the CURRENTMETER reads zero.
SECTION 8: PARTS ORDERING INFORMATION Replacement parts are available from Phenix Technologies, Inc. Changes to Phenix Technologies' products are sometimes made to accommodate improved components as they become available, and to give you the benefit of the latest technical improvements developed in our Engineering Department.
SECTION 9: RECOMMENDED SPARE PARTS Phenix Technologies recommends that the customer purchase and stock the following parts for normal maintenance of the unit. The recommended quantity should be sufficient to support the unit during normal operation. If the unit will be operated at an isolated site for an extended period or will be subjected to unusual stresses, a larger quantity of parts should be stocked as spares.
10-1 SECTION 10: RETURNED MATERIAL If for any reason it should become necessary to return this equipment to the factory, the Service Department of Phenix Technologies, Inc. must be given the following information: Name Plate Information Model Number Serial Number Reason for Return Cause of Defect If Phenix Technologies, Inc.
