9.2.2 Solenoid Valve Regulator
The Solenoid Valve Regulator test screen (figure 9.2.2A) allows control of the solenoid valves directly
by the operator. Pressing [Closed] or [Open] key will toggle the associated solenoid between the open
and closed states. As each key is pressed the key will change text and color, and the target solenoid
will make an audible “click”. If a key changes color without the accompanying click it is an indication
of a defective solenoid or a bad connection. The
[+], [++], and [+++] represent the fine, medium
and course regulator supply valves respectively.
The [-], [--], [---] keys represent the fine, medium
and course regulator exhaust valves respectively.
Applying a continuous touch to any of these keys
will open the respective regulator valve and in-
crease or decrease the system pressure. The [%]
key (top left) allows a collective adjustment of the
duty cycle of the regulator valves to adjust the
flow rate through the regulator. The Primary and
Secondary labels show the pressure sensed at the
respective transducers. The Rate [psi/sec.] label
indicated the rate of change of the system pres-
sure. See Figure 9.2.2B for the pneumatic sche-
matic for the solenoid valve regulator.

System pressure should not be driven above the range of the primary
transducer.
The valve isolating the secondary transducer should be closed before the
system pressure is driven above the range of the secondary transducer.
