McGunn Easy Series - Vending System

Removing the Vend Assembly

The Vend Assembly must be removed in order to access most of the electrical and electronic components on the inside of the door.
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.

Casting Repair

To repair any part of the casting assembly remove all tubes and turn the vend assembly upside down. Back off the set screw for the casting to service. Slide out the casting spindle. Pull the front of the casting free, then the front and rear casting bushing will come loose. Replace damaged parts and reverse process to reinstall.

Solenoids

While attempting to vend from the problem column, verify the solenoid energizes (pin pulls up) when the screen indicates it should. If the solenoid does not, check the connection to the main board. Check the voltage to the solenoid at the main board connection while attempting to vend to determine if the problem is the solenoid or the main board. Each solenoid is held to the bracket by its nut. To replace a solenoid remove first remove the bracket and cover assembly. Care must be taken to avoid twisting and thus damaging the solenoid wires while removing solenoid nuts. Solenoid wires must be routed through the bracket cover openings close to the door. The bracket cover prevents anything from weighing down the solenoid pins. Care must also be taken to ensure each solenoid cable is connected to the corresponding column connector on the J7 jack set.

Drop Sensors

If the safe vends properly but the tube count does not decrement or if the solenoid remains energized even after you physically vend a tube there is a problem with the vend drop sensor. Check the physical mounting of the vend drop sensor transmitter and receiver boards and check for any obstructions of the beam across the tray area. Check electrical connections at sensor boards (transmitter on hinge side, receiver on open side) and main board J21 and J25. Check continuity of sensor cables. Replace both boards only if no other problem is found. The Receiver module is the one on the open side (shown below). It has a three-pin jack and is electrically connected to J25 on the main board. The Transmitter module is mounted on the hinge side. It has a two-pin jack and is electrically connected to J21 on the main board.
