Activation Switch OFF (
FIG 8-B) button to turn key pad off and switch the
FIG 8-A) to minimize battery usage.
These controls have the following features to facilitate leveling:
• TO MAXIMIZE AVAILABLE LEVELER STROKE During the initial activation of
a pair of levelers following the
seconds the first pair of levelers extend, the opposite pair of levelers
will retract for two (2) seconds. This process will repeat for the first 60
continuous seconds of extension of first pair of levelers.
• FULL EXTENSION If a leveler is fully extended, its corresponding LED
will indicate this and further operation of that pair of levelers in the
extend direction is prevented. If the switch is held on, the second leveler of the pair will operate with its alternate pair partner leveler. (i.e.,
if the front two levelers are extending and the left front leveler
becomes fully extended, the right front leveler will continue to operate
and the right rear leveler will start to extend.) This is to keep the
frame from twisting.
• LOAD COMPENSATION If one leveler becomes disproportionally more
loaded than its pair partner, power will shut off to the first leveler. The
second leveler will continue to operate until the load is more balanced between the pair of levelers. Power to the first leveler will then
resume.
Hooking Up to Tow Vehicle / Retraction of Levelers
1. Have all slideout rooms retracted (in their inboard position) and
warn all persons to stand clear of RV.
