STATUS
V2
A 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 power surge. When the LED is ON, the valve is disabled. V1 is Valve
1. V2 is Valve 2.
To recover, press the Valve Reset button. If the problem persists, the pump may
need to be cleaned.
Each DV-6000, DV-7000, and DP Series dispensing valve uses a Valve Speed
potentiometer located on the Control Panel, just to the right of the Dispensing
Status controls. The Valve Speed potentiometer sets the valve motor speed,
which affects the amount of fluid dispensed.
Each DP Series valve uses an additional Valve Reverse Speed potentiometer to
adjust the valve motor reverse speed, determining the valve’s refill rate. These
control potentiometers are located at the rear of the machine, on the Electrical
Interconnect Panel (under the rear service shroud). The potentiometer labeled
Elec. 7 controls Valve 1 reverse speed; Elec. 8 controls Valve 2 reverse speed
(see Quick Refill)
Note: Speed control potentiometers are not used with the DJ-2100.
