The Proviso™ Plus P100A
The Proviso™ Plus P100A is a lift axle control system for trailers. It includes the trailer direction sensing system, perfected by the Reverse-A-Matic™. The P100A is also a stand alone device that is independent from the cab.
The P100A provides most of the Reverse-A-Matic™ RM-60 functionality and add a trailer load based control of the lift axle. When correctly configured, the lift axle will automatically lift when the trailer is empty and lower when the trailer is loaded.

How it works
Reverse Lift
The reverse lift feature uses the Wheel Monitor Reverse Sensor to determine the trailers direction. When the trailer has reversed approximately 8 inches, the reverse lift feature activates. The Reverse lift feature remains active until the trailer moves forward 100 feet without stopping.
Reverse Alarm
Similar to the reverse lift feature, the reverse alarm feature activates when the trailer has reversed approximately 8 inches. The reverse alarm feature remains active until the trailer stops for 5 seconds or begins to travel forward.
4-way Lift Feature
The 4-way lift feature can be activated by the driver at anytime, when traveling under 60km/h. The feature is activated by turning the 4-way flashers ON and OFF in the correct sequence. The 4-way lift feature will deactivate if the 4-way flashers are turned OFF or the trailer travels above 60km/h.
Load Control
The load control feature can lift and lower the lift axle based on the load condition of the trailer. When the fixed axle suspension pressure is above the lower down setting, the axle lowers. Oppositely, when the fixed axle suspension pressure is below the lift up setting, the axle lifts. Both the lift and lower settings are adjustable.
Steering Lock Control
The steering lock control feature can be used to lock the self-steering for straight operation. The feature activates the lock when the trailer is in reverse or traveling over 60km/h. The lock will deactivate below 60km/h and traveling forward.
