4.1.1 Valve #1
Next, select the model of Valve #1 from the drop-down menu.
This software allows for specific settings to be configured for each valve in the Valve
Options screen. Make the appropriate selections for the application requirements.
Example 1: The 780S Valve Options screen allows the User Operator to specify nozzle
air on/off delay.
Note: the default is a 0.24/sec nozzle air delay, but this setting is configurable from 0
to 5 seconds in 0.01 sec increments.
Example 2: The 790 Valve Options screen allows the Operator to select either constant
or pulsed pressure from the P2 (0~30 psi) channel. There is also the additional option of
having the fluid pressure turned off at the park location.
Note that when configured for Constant Pressure (P2) and Pressure Off at Program End
i.e. both boxes are checked as shown in the figure on the left:
• The fluid air is turned on during purging and program run.
• Aborting the program will turn off the fluid air.
Speed control is determined by applied voltage to the motor. This speed is maintained
through the use of a Back EMF circuit to ensure constant velocity. The range of operation
is from 10 VDC to 24 VDC in 0.1 VDC increments.
