1-7 Stall force calibration
If the system stalls out before reaching end of stroke, or if the room doesn’t seal as tightly as desired,
then stall force may be increased.
***CAUTION***
IF ROOM STALLS MID STROKE, MAKE SURE THAT THERE ARE NO OBJECTS IN THE WAY,
OR THAT SOMETHING HAS BEEN PULLED INTO THE SYSTEM, CAUSING RESTRICTED
MOVEMENT. ALSO CHECK SYSTEM VOLTAGE. EVEN THOUGH THE SYSTEM CAN RUN ON
AS LITTLE AS 8VDC, THE FORCE AVAILABLE TO MOVE THE ROOM IS REDUCED ON LOWER
VOLTAGE. IF THE ROOM IS FREE OF OBSTRUCTIONS AND VOLTAGE IS SUFFICIENT (12VDC)
AND THE SYSTEM STILL STALLS MID STROKE, ONLY THEN SHOULD STALL FORCE BE
INCREASED.

hole. Directly below the sealed hole is a potentiometer. Using a small screwdriver increase the stall
force by turning clockwise, turning counter-clockwise will reduce stall force. Once the desired setting
has been reached press the mode button and both led’s will light up. The board is now back in auto
mode.
It is desirable to increase the stall force only enough to insure proper functioning of the room.
Increasing the setting beyond the amount needed only shortens system life.
Caution!
During this override procedure the motors are not synchronized. Visually watch
the room, if one side is moving signicantly slower then the other (or not at all)
then immediately stop and use the “motor disengagement” override method.

1-8 Error codes
During operation when an error occurs the board will use the led’s to indicate where the problem
exists.

When an error code is present, the board needs to be reset. Energizing the extend/retract switch
resets the board. Energize the extend/retract switch again for normal operation.
