VALVE

STATUS

VALVE STATUS LED turns ON if there is a problem

with the fluid pump motor. It usually indicates that the

pump electronics (overcurrent protection circuitry) has

detected a surge of power. When the LED is ON, the

valve is disabled. V1 is Valve 1. V2 is Valve 2.

To recover, press VALVE RESET. If the problem

persists, the pump may need to be cleaned.

Each DV-6000, DV-7000, and DP Series dispensing

valve has a Valve Speed Pot located on the Control

Panel, just to the right of the Dispensing Status

Controls. The Valve Speed Pot sets the valve motor

speed, which affects the amount of fluid dispensed.

Each DP Series valve has an additional Valve Reverse

Speed Pot to adjust the valve motor reverse speed,

determining the valve’s refill rate. These control pots

are located at the rear of the machine, on Electrical

Interconnect Panel. The pot labeled Elec. 7 controls

Valve 1 reverse speed; Elec. 8 controls Valve 2

reverse speed.

Note: Speed Controls are not used with the DJ-2000.

VALVE
