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.

Press mode button 4 times quickly, then press a 5

time and hold for approximately 5 seconds. The

red led will start to flash, flash, flash, … Break the seal on the cover over the stall force calibration

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 significantly 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.

For motor specific faults the green led will blink 1 time for motor 1, and 2 times for motor 2. The red

led will blink from 2 to 9 times depending on the error code.

The error codes are as follows:

Battery drop out: Battery capacity low enough to drop below 6 volts while running

Low battery: Voltage below 8 volts at start of cycle

High battery: Voltage greater than 18 volts

Excessive motor current: High amperage, also indicated by 1 side of slide continually

stalling.

Motor short circuit: Motor or wiring to motor has shorted out.

Hall signal not present: Encoder is not providing a signal. Usually a wiring problem.

Hall power short to ground: Power to encoder has been shorted to ground. Usually a wiring

problem.

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.
