Operation Controls
You can adjust the speed of each fluid pump during dispensing operations. The fluid pump
pressure and fluid syringe pressure are controlled by dispensing system regulators. You can
also adjust the toggle speed for Pump 2 and the spacing between the fluid pumps, but the
spacing is set at the factory and should not need to be changed.
Valve 1 and Valve 2 indicators are located near the Valve Speed Controls. (See the
dispensing system operations manual.) When the indicator light comes on, the fluid pump is
malfunctioning.
Toggle Up/Down and Pump On/Off commands are programmed into the dispensing program
using Fluidmove. For more information on how to insert these commands, contact Asymtek
Technical Support.
Three adjustments must be made to setup a second valve:
• Pump motor speed
• Valve air pressure
• Fluid air pressure
Adjusting Pump Motor Speed
Fluid pump motor speed is the speed of the motor driving the feedscrew inside the pump.
The pump motor speed is controlled by the Valve Speed Controls labeled
Valve 1 and Valve 2
on the Auxiliary Control Panel on Millennium Series systems or the Control Panel of
Century Series systems.
For details on operating the fluid pump for your application, see the pump installation and
operation manual, which is a tabbed section in your dispensing system operations manual.
To adjust the fluid pump motor speed:
1. Rotate the Valve Speed
Controls until you have the desired pump flow rate.
2. Reset the locking tab on the control dial.
3. Measure the flow rate.
Adjusting Valve Air Pressure
The DP-2000/3000, DV-06, DP 3000, DV-6000 and DV 7000 fluid pumps use the Valve
Pressure Controls to control the dispensing process. All other pumps use the Fluid Pressure
Controls to control dispensing. See the dispensing system operations manual for the location
of the regulators and instructions on how to change the settings. See the fluid pump
installation and operation manual for correct pressures and more detailed setup information.
