4.1.1 Valve #1

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.
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 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.
