4-Way ScreenWall ElectriMask: Owner’s Manual 21
Problem description Probable cause Action to take
Mask continues past bottom stop
position. White limit switch is out of
adjustment. Readjust the DOWN limit switch.
Refer to figure 15. See pp. 17-18
of this manual.
Batten retracts too far into frame. Yellow limit switch out of
adjustment. Failure to correc t
can damage motor and screen.
Do not use the unit until this
problem is resolved. Have a qualified se rvice person
readjust the UP limit switch. Refer
to Figure 15. See pp. 1 7-18 of this
manual.
Horizontal mask jams upon
retraction. The unit was not level and plumb
when mounted. Remount the unit making sure
that it is level and plumb.
Motor shuts off. Motor has been
in use for more than 2 minutes. Motor is designed for short
operations (lowering and
retracting), not continuous duty.
Longer operation, such as during
setup and positioning, causes the
motor to overheat and shut off. Allow the motor to cool down.
Complete cooling can take an
hour or more. Heat gain is
cumulative and takes time to
dissipate. If motor use is initiated
before it has cooled completely,
the motor will shut down again
when it reaches maximum
temperature.
Any controller (e.g., STI, LVC,
etc.) fails to operate motor.
Dirt, finger prints, marks, etc. on
screen surface. Improper handling of screen. Brush off or use a mild detergent
solution with clean rag or cotton
swab.
Indentations appear on screen
surface. Debris or particles adhering to
screen due to static cling. Check back of screen; gently
brush debris away by hand.
