Problem description  

Probable cause  

Action to take  

Screen won't operate.  

No AC power available.  

Outboard switching problem.  

 

Check to see if the circuit breaker has 
switched off.  Reset if needed.  

Check outboard switching apparatus.  

Check voltage availabi lity. Contact an 
electrician.  

Screen won't roll up or down 
(even though power is 
available).  

Bad connection at switch.  

Polarity of STI line may be bad.  

Have an electrician or qualified service 
person check the connection as follows:  

·

  If you have a 

low voltage control

 unit, 

check switch -line connections.  

·

 

If you have a 

screen trigger interface

check line connections, or the mini -plugs 
at the screen input or projector output.  
Check 12V DC line for correct polarity. 
Contacts may be sticking —tap relay to 
free contacts.  

Screen roller chatters when 
power is activated.  

Can be caused by voltage drop, 
bad connections, or a defective 
switch. 

Have an electrician or qualified service 
person check all hook -ups including all 
outboard wiring.  

Unit hums in up mode.  
(Screen has already 
retracted.)  

The screen batten is retracting too 
far into the case. 

Failure to 

correct can damage motor and 
screen.  Do not use the unit until 
this problem is resolved.

 

Have a qualified service person adjust the 
yellow UP limit switch. Turn  the adjusting 
screw clockwise. See pp. 10 -11 of this 
manual. 

Screen drops when up 
direction is activated 
(grinding noise occurs).  

Drop in voltage.  

Screen motor requires full voltage. Have an 
electrician or qualified service person check 
available voltage.  

Screen continues past 
bottom stop position.  

White limit switch is out of 
adjustment.  

Readjust the white DOWN limit switch. See 
pp. 10-11 of this manual.  

Batten retracts too far into 
case. 

Yellow limit switch out of 
adjustment.  

Failure to correct 

can damage motor and screen. 
Do not use the unit until this 
problem is resolved.

 

Have a qualified service person readjust the 
yellow UP limit switch. See pp. 10 -11 of this 
manual. 

Motor shuts off.  Motor has 
been in use for more than 
2 minutes. 

Motor is designe d 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.
