Adjusting Limit Switches
Limit switches are located on the left side of the screen and
inside the housing. The limit switches should only be adjusted
with the provided adjustment tool.
The limits that are set determine the point where the screen will
stop lowering or retracting. By initially adjusting the lower limit,
the screen will stop at the perfect location automatically for
maximum convenience.
UPPER
LIMIT
The upper limit switch is yellow and does not need to be
adjusted as it is pre-set from the factory. If absolutely necessary,
turning the grey upper limit switch counter-clockwise will cause
the upper limit to be closer to the housing and clockwise will
make the upper limit further away from the housing.
LOWER
LIMIT
The lower limit switch is purple and can be adjusted for
increasing or decreasing the amount of upper black drop on
your screen.

To decrease the amount of black drop, first lower the screen
and turn the purple lower limit switch clockwise twice.
Retract the screen then lower the screen again and where it
stops is the new lower limit. Repeat until the desired height is
reached.
The first time the lower limit is being adjusted, it may take a
few cycles for the screen to move up. This is normal and be
patient as to not damage the screen. If the screen pauses
during adjustment, wait 5 minutes for the motor to cool and
continue adjusting.

To increase black drop, lower the screen so it is fully
extended. Using the adjustment tool, turn the purple limit
switch counter-clockwise and the screen will drop in small
increments without needing to cycle the screen. Continue
rotating until the screen is in the desired position.
Overheat Protection
The motor used in this screen has
an overheat protection feature.
When the motor runs for an
extended period, the motor will
stop working to prevent
overheating which would cause
damage to the motor. If this
happens, wait 15-20 minutes for
the motor to cool off and
continue use.
Fuse Replacement
There is a fuse located on the screen’s circuit board to prevent additional electrical damage
to the unit in an electrically unstable environment. If the screen appears to have no power
while the outlet provides po
wer, the fuse may be blown. It is the user’s responsibility provide
an electrically stable environment for the unit, and to replace the fuse if required.
Remove the screws on the side of the housing with the power cable and take off the side
covering. Carefully pull out the circuit board while ensuring no wires are damaged. Take off
the black plastic cover labelled “FUSE” and see if the fuse is blown. If this is the case, remove
the fuse from the plastic casing using tweezers or a lever to remove. Replace the fuse with
the same model as the one removed. The model will be labelled on the fuse. Replace the fuse
cover, put the circuit board back in its original location and replace the side cover.
