McGunn Easy 120 - PowerSymptomsIf the unit has no power, the display will be off, both LEDs will be off, and there will be no response from the keypad.External Power The
unit is powered by an external DC power supply (Part 15000346). Measure the
output voltage to determine power supply operation up to the back of the
safe (only +12 VDC and +5 VDC and common are used). If the problem is external
verify the outlet has power and replace the power supply if faulty. If the
power supply output is good and everything is connected properly, the problem
is inside the safe.
Internal PowerPossible problems include the cable harness, the LCD display module, or the main board. Internally power runs on two sets of wires from the rear of the safe through an armored cable to the door. Inside the back of the safe: two black wires carry power common from Pin 1 of the jack to J26 (main board) and the LCD module. A blue wire carries +12 VDC from Pin 3 on the jack to J26 on the main board. Two red wires carry +5 VDC from Pin 5 of the jack to the LCD module and main board J26.Internal ConnectionsBack wall, near top, hinge side: Power Routing at Main Board:  |
