Multi-Valve Unit (MVU) Overview The MVU module is designed to dispense up to 6 beverages and/or shots through one dispense nozzle. The MVU consists of: 1. An electronic board 2. Touch pad which is used to both program and dispense drinks solenoids (one for each circuit) 4. 8 flow controls (one for each circuit). a. Plain water (PW) b. Soda water (SW) c. 6 syrup dispense locations (buttons A through F). d. The flow controls are the Lancer LEV version shut-offs Positions A and D are plumbed through the cold plate meaning that the syrup is chilled in each of those locations. Positions B, C, E, and F bypass the cold plate so the syrups are not chilled. That is why they should not be used for carbonated beverages. The water flow controls are green, and the plain water control is PW. The carbonated water is CW. There are no stickers on the water flow controls. The syrup flow control modules are red and correspond to the touch pad as shown in the illustration (touchpad position A activates solenoid A). The 8 solenoids are 24 VDC, activated by the touch pad, and controlled by the MVU circuit board TCCC. CSO Learning & Development. All Rights Reserved 11

Carbonation System The carbonating system consists of the following components: Electrode - When the water level in the carbonator tank falls below the tip, the liquid level control turns on the pump

30 Carbonation System The carbonating system consists of the following components: Electrode - When the water level in the carbonator tank falls below the tip, the liquid level control turns on the pump motor for 5.5 seconds. If the water level does not reach the tip, the motor continues to run in 5.5 second intervals until the water touches the tip. Once the water reaches the tip, the motor will stop running at the end of the 5.5 second interval. The black wire and the green (ground) wire complete the circuit inside the tank. Picture Frame Carbonator Tank (embedded in cold plate oz capacity) CO 2 Check valve - Prevents carbonated water from backing into the CO 2 system Backflow Preventor - Prevents carbonated water from backing into building's water supply Relief Valve - Vents the carbonator when pressure exceeds 240 psig 2008 TCCC.

31 Carbonator Pump - Consists of the following components: Pump Motor - Standard 1/3 hp motor Water Pump - Standard 100 GPH 250 psig bypass Liquid Level Control - Operates as a timer. When liquid level drops below the probe tip, the control turns on the carbonator pump motor for 5.5 seconds and then shuts off. The liquid level control will time out after 3 minutes of cycling on and off if probe fails. A light on the liquid level control will blink as well. Water Pressure Regulator The water regulator restricts the incoming water pressure to 50 psig for water entering the carbonator tank. Since the CO 2 pressure is set to 75 psig, this creates more than enough pressure difference between the water and CO 2 gas to create soda water. Electronics The MVU valves are controlled by the unit s pc board. The PC board receives its power from a 120 VAC to 24 VAC transformer. The MVU board controls all beverage dispensing functions for the 6 buttons on the touchpad. It receives 24 VAC from the transformer and rectifies it to 24 VDC to operate the MVU dispensing valves. A ribbon cable connects the touchpad to the board and a wire harness connects the solenoids to the board. The portion control function only works when the dip switches are in the OFF position as shown in the illustration TCCC. CSO Learning & Development. All Rights Reserved 31

32 Troubleshooting Troubleshooting focuses on two key areas of the dispenser, the carbonation system and the electronics as the remainder of components such as LEV s are standard on most drop-in dispensers. Carbonator Troubleshooting Failure Mode Possible Cause Resolution CO 2 only dispensed at valve Carbonator motor will not start Unplug probe cable from the LLC If motor starts, replace probe If motor doesn't start, verify 120 VAC at load and line terminals of LLC If you have 120 VAC on line and load, replace motor If you have 120 VAC on line but not at load, replace LLC No VAC at either, check service cord Water sprays out relief valve Drinks Foam Excessively Carbonator cycles on and off continuously in 5 second intervals and times out after 30 continuous cycles. CO 2 pressure set too high. Dirty Nozzles and source Unplug probe cable from LLC cable and jumper the green and black wires with a conductor on the LLC side of the probe cable and plug in motor If motor runs, Inspect probe cable at LLC to ensure proper connection. Replace LLC if Black and Green wires are properly connected If motor doesn't run, ensure the Black and Green wires are making contact in the connector. If they are, replace the probe. Adjust HP CO 2 pressure to 75 psig Clean nozzles as necessary Drinks taste flat - Too little carbonation Pump runs and times out after 30 cycles. Low or no CO 2 pressure Procon pump worn, not atomizing water Water pressure too high Probe is defective. Set CO 2 pressure to 75 psig or replenish supply Replace pump and/or motor Check pressure at pump platform regulator outlet, replace regulator if over 50 psig. Unplug probe. Pump motor should run. If it does, replace probe. If it doesn t run, replace liquid level control TCCC. CSO Learning & Development. All Rights Reserved 32

33 Electronics Troubleshooting The electronic boards on the Bevariety TM dispenser have only a few connections and are they are relatively easy to service; however, you have little room to work with at the top of the beverage dispenser so it is best to remove the board from its standoff brackets if any connections need to be made. Note: Handle the boards with care as they damage easily! Failure Mode Possible Cause Resolution No syrup or water on either MVU No power to MVU board or failed MVU board Check for lights on the MVU and/or MVU board. If no lights, check for power from the transformer (24-28 VAC Load Side). Reset if tripped. If 24 VAC coming to board and no lights showing, replace board. Water only is dispensedwhen button is pressed. BIB has been checked. Syrup only dispensing on MVU Portion control board not working Broken wire on harness connecting to MVU or bad pin Failed solenoid assembly Failed board No water to MVU but water pouring at LEV s MVU dip switch in wrong position. Check for 24 VDC at solenoid. If not, repair/replace harness. If 24 VDC present at solenoid, repair/replace solenoid assembly Check for 24 VDC out from board. if 24 VDC not present, troubleshoot board and transformer. Check for 24 VDC at water solenoid, if 24 VDC present, repair solenoid assembly If 24 VDC not present, troubleshoot board and wiring harness. Set switches to correct position TCCC.
