Sleep Mode; Electric Controller Unit Testing/Adjusting - Dexter Laundry DX Series Service Manual

Sleep Mode

DX Series E/H Actuator will automatically go into sleep mode after
5 hours of not receiving input from blue (brake controller) or yellow
(breakaway switch) wire to conserve power consumption on trailer
battery. The sleep mode timer will reset if the power/ground is removed.
The DX Series E/H Actuator will wake up from this sleep mode on
the first brake request signal from the tow vehicle's brake controller
(blue wire). Using the breakaway switch to wake up the DX Series E/H
Actuator from sleep mode is not recommended.
Disconnect battery from DX Series E/H Actuator if trailer is going to be
stored for longer than one month.

Electric Controller Unit Testing/Adjusting

1. Adjust the gain setting on the electric brake controller to a mid
range setting.
2. Drive vehicle at 10 to 15 m.p.h.
3. Apply the brakes. If braking is too severe, adjust the gain
setting down to decrease pressure and retest. If braking is
inadequate, increase the gain setting on the electric brake
controller and retest.
4. Repeat this process until the brakes respond appropriately.
CAUTION
!
The appropriate pressure setting will vary depending on the weight
of the load being transported on the trailer, weather conditions
and road conditions. The "Testing and Adjustment of Electronic
Controller Unit" procedure should be repeated each time the
trailer is used. Failure to properly adjust the Dexter DX Series brake
actuator may result in poor brake performance and could result in
serious or fatal injuries and/or property damage.
