McGunn Easy 120V/120A - Front Panel

Front Panel Assembly

The keypad membrane and LCD display module are mounted on the front panel assembly. The panel itself is mounted to the door with screws through the front door. To remove the assembly, the door must be open and the Vend Assembly must be removed (see procedure below). All wires from the front panel must be disconnected before attempting to remove the display module otherwise accidental wire damage is very likely.

Keypad

To replace the keypad, the door must be open and the vend assembly must be removed. The keypad membrane is attached with adhesive to the surface of the front panel. A thin ribbon cable connects the keypad to the main board (J5).
1. Remove the vend assembly (see below).
2. Disconnect the keypad ribbon cable at the main board (J5). The connector at the main board slides off.
3. Peel off the defective membrane and gently pull the ribbon cable out.
4. Fish the ribbon cable of the new membrane through the opening.
5. Remove the backing and stick the membrane to the panel.
6. Connect the ribbon cable to J5 on the main board.
7. Verify keypad operation.
8. Replace the vend assembly.

LCD Module

The LCD module is mounted inside the front panel. It receives 5 VDC directly and a ribbon cable connects the display to the main board (J23). Verify power before replacing the display module.
1. Open the safe door.
2. Remove power from the safe.
3. Remove the vend assembly.
4. Disconnect the 5 VDC supply at the Molex connector.
5. Pull the tab on the ribbon cable connector toward you to release the ribbon cable from the connector (J23).
6. Disconnect the keypad ribbon cable at the main board (J5). The connector at the main board slides off.
7. Remove the mounting screws to remove the front panel from the safe.
8. Repair or replace the LCD module as needed.
9. Reverse the above steps to restore the safe.

Remove Vend Assembly to Access Electronics

The Vend Assembly must be removed in order to access components inside the front panel.
1. Pull off all ten of the vend knobs from the front.
2. Remove the Vend Drop Sensor Boards. To remove the boards use a phillips screw driver and remove the two mounting screws from each board.
3. Using a 7/16” hex nut driver or wrench remove the six nuts (two on the right, four on the left) holding the metal Vend Assembly to the door. Gently slide the entire assembly back and set it out of the way.
4. Reverse these steps to reinstall. Be careful to avoid pinching wires.
