Pressure Switch (10 PSI / 0.7 BAR)
Also see Figure 3-1: “Pressure Switch Mounting” on page 13.
The pressure switch ensures that 10 PSI (0.7 BAR) is available from the
suction or INLET source for AutoFill operation. Pressure less than 10 PSI
disables the AutoFill system and causes the SVS valve to CLOSE.
2.2 CLASS 1 (INTELLI-TANK) LEVEL INDICATOR
(HALE P/N: 106299)
Four (4) illuminating lights (RED) indicate the
water level in the tank. (See Figure 2-2: “Intelli-
Tank 4-Light Indicator.”)
When the tank level drops to 75% of FULL, the
AutoFill System engages to refill the tank(s) back
to an optimum or FULL level. The Intelli-Tank
Level Indicator shows the entire process by cycling
through these four lights.
Also see Intelli-Tank Water/Foam Level Gauge
Manual, p/n: 106759 for more detailed information.
This manual is provided as a separate attachment,
located at the back of this manual.
2.3 DRIVER MODULE, HARNESSES AND RELAYS
The control center of the AutoFill system lies in the Class 1 Driver Module,
interconnecting harnesses and control relay assembly. Information on the
water level in the tank(s) is received from the Intelli-Tank 4-Light Level Indi-
cator. Signals are then sent out to activate the Hale SVS Valve Actuator
System and allow water flow to refill the tank(s).
“Fill Required Signal” – Driver Module
Information on the water level in the tank is received from the Intelli-Tank 4-
Light Level Indicator (p/n: 106299). This information is received by the
Driver Module (p/n: 106877).
