To operate the system in automatic mode, simply turn the power switch located on the control
box door to the “ON” position. When the power is turned on, the controller will go through an
initialization routine to determine which tank is going to be used first, or if either or both need
filling. It is important to verify that all valves are open or closed, according to the following table.
✦
In automatic mode, all manual bypass handwheels on the solenoid
valves must be in the closed position (handwheel unscrewed away from
the solenoid valves allows the valve to close normally).
If the system has been shut off, upon turning the power back on, the controller will go through
the initialization routine and begin controlling. Nothing is lost when the controller is turned off.
The system does not have to be turned off in periods of non-use (over-night, weekends etc.).
Turning the system off will de-energize the solenoids and may be advantageous if the system is
not going to be used for an extended period of time (greater than four days). However, this is
not necessary, as the system will continue to monitor itself and maintain pressures and liquid
levels such that it is ready for immediate service. When looking at the front of the skid, the
Laser-Cyl on the right is considered Tank #1

The manual by-pass feature on the solenoid valve operates such that turning the valve
handle in (closer to the valve body) will open the valve. Turning the valve handle out (away
from the valve body) will close the valve. This is also labeled on the valve handle.
