A. Three systems in the Volumetric Valve work together to maintain an accurate syrup to water ratio:
• The circuit board with its computer.
• The water measuring system.
• The syrup injecting system.
B. Set the ratio by using the hand held programmer (Lancer PN 52-1420/02; CCPN 532179).
C. When a customer activates the valve, the water starts owing to the nozzle. The ow washer en-
sures that the water does not ow too fast.
D. The paddle wheel in the owmeter begins to spin, sending signals to the circuit board (see below).
E. The computer on the circuit board monitors the signals and determines when to inject syrup into the
water stream. The circuit board energizes one syrup solenoid and then the other. This alternating
action injects a metered amount of syrup into the water. This happens seven to eight (7-8) times a
second (see Fig. 2 and 3).
F. The circuit board indicates which solenoid is activated with the LEDs mounted on the front of the
board. The green LED corresponds to the water solenoid and the red LEDs correspond to the syrup
solenoids.
