Page 3: An Overview
AN OVERVIEW This manual provides the operating and maintenance procedures for the Mark II series Foxcart Ground Power Units. The first part of this manual covers operating procedures that are typical for aircraft Ground Power Units operating from an alternating current source. Preparation for use and routine maintenance are also covered. -
Page 4: Purpose Of Equipment
PURPOSE OF EQUIPMENT The Foxcart ground power unit is designed to provide smooth, high current DC power to aircraft during engine starts or ground maintenance. The Foxcart, when used as an external DC source, eliminates or minimizes excessive current drain from the aircraft’s battery and battery relay contacts. It is also designed as a low profile unit that requires minimum ventilation and is easily moved in a crowded hangar by one person. -

MODELS All units are provided in functional configuration with standard 15 Ft. DC cables, DC plug and 50 Ft. AC cable with Hubbell 460P7W AC plug. MODEL 1200 This is a single-phase power input unit and should only be considered if three-phase power is not available. - Page 6 MODEL 2000 This is our HI-LINE unit that delivers maximum power output. OUTPUT VOLTS: 28 VDC PEAK DC OUT: 2000 AMPS CONTINUOUS DC OUT: 1000 AMPS INPUT POWER REQUIRED: 208-240 VOLTS PEAK * THREE PHASE 100 AMPS/PER PHASE 380-480 VOLTS PEAK * THREE PHASE 70 AMPS/PER PHASE 100 AMPS SERVICE OTHER VOLTAGES AVAILABLE UPON REQUEST.

Page 8: Description
DESCRIPTION The Foxcart is enclosed in an all-steel chassis frame with a three-piece steel box siding. The power cables can be wrapped around the handles or coiled on top for storage. The wheels can be locked in place to prevent movement. Both power cables are clamped internally to the frame for strain relief. Location and identification of the controls are shown in Figure 2. -
Page 9: Preparation For Use
PREPARATION FOR USE The Foxcart is shipped completely assembled except for the handles. Attaching hardware is in- serted into the mounting holes where the handles are to be mounted for your convenience. Verification of Options and Strapping should be checked before use. Incorrect Primary Supply Voltage or Strapping could cause damage or improper DC Output. -
Page 10: Operation
OPERATION Move the Foxcart into position and set the wheel brakes. Ensure that 14/28-volt selector switch is in the same voltage range as the Aircraft. (If cart is so equipped with this optional feature). Plug the Foxcart Input Power Cable into the AC Outlet. Switch the Foxcart ON/OFF breaker to “ON”... -
Page 11: Preventive Maintenance
PREVENTIVE MAINTENANCE Routine maintenance should be performed periodically. Since the wheels and fan motor are the only moving parts on the Foxcart, maintenance is kept to a minimum. Oil fan motor and all other moveable parts. Using compressed air and a dry cloth, clean accumulated dust and grime from unit. Perform visual inspection and tighten any loose nuts and bolts. -
Page 12: Troubleshooting
If the Foxcart has been operational for a period of time and has failed, use the following steps to assist in isolating the problem. If the problem cannot be isolated, please call Foxtronics for assistance. The phone number is (214) 358-4425. Replacement parts may be ordered from the same number. - Page 13 Inspect the interior of the Foxcart for any signs of arcing or burning, such as wires or connections. Remove rectifier bus bars and any attaching wiring. Using a DMM Diode Tester, test all the diodes. All readings should be similar in the forward direction and infinite in the reverse direction. Remove buss bars and attaching wires from reverse current diodes.
