The Proviso™ Plus P160A

The Proviso™ Plus P160A is a lift axle control system for trailers. It includes the trailer direction sensing system, perfected by the Reverse-A-Matic™. The P160A is also a stand alone device that is independent from the cab.

The P160A combines the multiple Lift axle control of the RM-60 with the load based control of the P100A. The P160A introduces the ability to control multiple axles at different weights. The P160A also allows for a 3rd, Smart lift axle control

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 axles 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.

The speed based lock is required by SPIF on trailers with lift axles behind the primary group.

ABS Bulb Check

The ABS bulb check feature is designed to help meet the enhanced braking requirements SPIF has on 5 and 6 axle trailers. The feature powers the light 3 times when the RM-60 first receives power. The operator can verify that the ABS warning light is functional before beginning to travel.

Smart Lift Axle Support

A 3rd lift axle output is provided to support Smart Lift Axle’s (SLA’s). With SLA’s being straight lift axles and the requirements put on the SLA control by SPIF, the lift axle control of all 3 axles changes. The changes include enforcing that the SLA axles are always lowered before the self-steering axles, disabling the reverse and 4-way lift features on SLA’s, and lowering the SLA’s based on the parking brake. For more detail about the SLA support, contact Wheel Monitor.
