Function
Action
Reason/Examples
1
ON
Operates only when
ignition IS present.
The unit will operate only
when the yellow ignition
wire receives +12VDC.
If you want to control
items when the ignition
is ON.
OFF
Operates only when
ignition IS NOT
present.
The unit will operate only
when the yellow ignition
wire is NOT receiving
+12VDC.
If you want to
raise/lower your trunk
when the car is OFF.
2
ON
Auto return to
position #1 with loss
of ignition.
Auto return to
position #2 with
ignition.
When +12VDC is removed
from the yellow ignition wire
the actuator will travel to
position #1.
When the yellow ignition
wire receives +12VDC the
actuator will travel to
position #2. Manual control
is available when the yellow
ignition wire receives
+12VDC.
If you want your trunk,
running boards,
steering column, etc. to
move automatically
when you turn the
ignition ON/OFF.
NOTE: DIP switch #1
must be ON for
functions of switch #2
to work.

When the key is turned ON
or OFF, the actuator will
remain at the same location.
If you do not want

3
ON
2 stage feature ON. This feature works after programming a start and end
point. Once in the run mode, pressing button 1 will initiate the two stage
sequence by moving actuator 1 from the preset start point to the end point.
Once actuator 1 has reached its end point, actuator 2 will begin moving from
the preset starting point to the end point. Pressing button 3 will reverse the
sequence, retracting actuator 2 first, then retracting actuator 1, both back to
the starting point. Pressing button 2 will only move the actuators 1 stage.
For example, after pressing button 2, if the actuators were at their starting
point, the controller will only move actuator 1 from the starting point to the
end point. If the actuators were at their end point, the controller will only
move actuator 2 from its end point to the start point. Pressing button 1 or 3
after pressing button 2 will complete the second stage of the sequence.
OFF
2 stage feature OFF.
4
ON
Retreat safety ON. In this feature, the controller will be able to sense if
something is in the way that is preventing the actuator from retracting
completely. The controller will do a speed check after reading current
actuator position value, retract a little, and perform another speed check.
Speed check will respond “normal” or “error”. If there is an “error” response,
the actuators are to stop immediately and extend to their maximum preset.
OFF
Retract safety OFF.
