• Specifications for system operation <--- CLICK HERE to open / Close

  • GENERAL SYSTEM OPERATION
    THE SYSTEM IS DESIGNED TO TURN ON AN AIRCRAFT COMMUNICATION RADIO AND / OR AUDIO PANEL WITH A SINGLE PUSH BUTTON SWITCH. WHEN THE BATTERY MASTER SWITCH IS TURNED ON THE GC-10 IS DESIGNED TO DISENGAGE FROM THE BATTERY AND CONNECT TO THE REGULAR AVIONICS POWER BUS.

  • POWER SWITCHING CAPABILITY
    THERE ARE THREE SETS OF RELAY CONTACTS: PIN's 9, 3, 2 are 5 AMP's @ 28 VOLTS; PIN's 10, 4, 1 are 5 AMP's @ 28 VOLTS; and PIN's 13, 12, 5 are 3 AMP's @ 28 VOLTS. YOU MAY USE THESE CONTACTS AS SEPARATE OR PARALLELED AS REQUIRED BY YOUR CIRCUITRY.
    
    IF GC-10 POWER RATING IS TOO LOW FOR YOUR COMMUNICATION SYSTEM YOU MAY WANT TO WIRE A HIGH POWER RELAY / SWITCH FROM THE GC-10 RELAY CONTACTS TO A SECOND HIGH POWER RELAY, AND USE THE GC-10 AS YOUR CONTROL RELAY IN THE SYSTEM.
    
    WITH ONE GROUND CLEARANCE SWITCH IT IS ALSO POSSIBLE TO CONNECT SEVERAL GC-10 UNITS IN PARALLEL AND ACTIVATE THEM ALL AT THE SAME TIME.

  • GROUND CLEARANCE SWITCH
    ALMOST ANY STANDARD PUSH BUTTON SWITCH WILL WORK. A SNAP ACTION SWITCH IS RECOMMENDED WITH A LIGHT TO SHOW ACTIVATION OF THE GROUND CLEARANCE CIRCUIT FOR THE PILOT. (REFER TO SCHEMATIC FOR CORRECT INSTALLATION).
    
    THE GROUND CLEARANCE SWITCH SHOULD USE A 22 GA SHIELDED WIRE FROM THE SWITCH TO THE GC-10 GROUNDING THE SHIELD TO PINS 14 OR 15 OF CONNECTOR J1. NOTE: THE CIRCUIT ACTIVATES WITH A PULSE FROM THE SWITCH AND HOLDING DOWN ON THE SWITCH WILL NOT ACTIVATE THE CIRCUIT. THE CONTINUOUS SWITCH CURRENT, IF HELD DOWN, WILL BE APPROXIMATELY 3 mA.

  • AIRCRAFT BATTERY MASTER SWITCH
    TO DISENGAGE THE GC-10 THE BATTERY MASTER SWITCH MUST BE CONNECTED TO THE GC-10 . WHEN THE SWITCH IS TURNED ON A SIGNAL IS SENT TO THE GC-10 CONTROL CIRCUIT TO TURN OFF THE RELAY IN THE GC-10. (REFER TO SCHEMATIC FOR CORRECT INSTALLATION).
    
    NOTE: YOU DO NOT HAVE TO USE THE BATTERY MASTER SWITCH TO DISENGAGE THE GC-10, ALTHOUGH IT IS SUGGESTED THAT YOU DO SO. HOWEVER, IF YOU WANT A SEPARATE SWITCH TO TURN OFF THE GC-10, YOU MUST USE A SWITCH THAT WILL HANDLE A PEAK CURRENT OF 1 AMP.
  • INSTALLATION OF THE GC-10 IN AN AIRCRAFT
    ONLY A QUALIFIED AVIONICS SHOP, OR AVIONICS PERSON, SHOULD INSTALL, ADD / OR CHANGE ANY WIRING IN ANY AIRCRAFT OR AIRCRAFT SYSTEM.
    
    THE SCHEMATIC ON THE REVERSE SIDE IS A GENERAL GUIDELINE ON HOW TO INSTALL THE GC-10 IN EXISTING OR NEW INSTALLATIONS AND DOES NOT PERTAIN TO ANY ONE TYPE OF RADIO SYSTEM. YOUR PARTICULAR SYSTEM MAY REQUIRE MORE, OR DIFFERENT, CIRCUIT BREAKERS AND / OR LIGHTING.
