Description
The NON-SPIF Box overrides the Proviso Plus systems when SPIF compliance is not required. For example, when operating outside of Ontario.
The Control Box offers a ball valve to select SPIF or NON-SPIF control of the axle. When in NON-SPIF mode, the position of the axle can be controlled using the manual override “Tee” handle or by powering the solenoid. The pressure applied to the lift axle can be controlled using the regulator.
When in SPIF mode, the Lift axle is controlled automatically, as if the NON-SPIF control Box was not there.
