HALL EFFECT SENSOR ADJUSTMENT

NOTE: Normally the hall effect sensor does not need adjustment, but may go out of alignment due to shipping vibration or rough handling.

These operators use an internal entrapment protector system. This system consists of the control board, magnet, and hall effect sensor. It may become necessary to adjust the sensor for correct alignment. To do so please perform the following steps:

1.The hall effect sensor must be centered over the magnet. Adjust with horizontal screws.

2.The hall effect sensor must be level.

3.The hall effect sensor air gap should be adjusted to

.010 - .015 of an inch. (The thickness of a business card may be used to gauge the correct distance). Adjust with vertical screws.

WARNING

To reduce the risk of SEVERE INJURY or DEATH:

• Disconnect power BEFORE performing ANY adjustments.

FORCE ADJUSTMENT

MOTOR LEARN FUNCTION (FORCE PROFILE)

This function is preprogrammed at factory. If either board or motor is replaced, the controller will need to be programmed to “LEARN” the specific motor RPM profile of your operator. Switch “S3” is provided for this. This is important for accurate force control. Failure to do so may result in improper and unsafe operation.

NOTE: Motor Learn must be performed in stand alone mode.

1.Detach the unit from the gate, the motor needs to be learned without a load. (Do not use the manual release, the limit shaft must be turning during learn sequence.)

2.Press the motor learn button. The yellow LED should start to flash rapidly.

3.Push and hold down either the open or the close buttons. The motor will run for a few seconds and then stop. If the LED goes out the motor is learned. If the unit activates a limit before completing the learn or some other error occurs the LED will go back to on continuously. If this happens try learning while running in the opposite direction.

4.Reconnect the unit to the gate, reset the limits and adjust the force control.

FORCE CONTROL

Set the force control pot such that the unit will complete a full cycle of gate travel but can be reversed off an obstruction without applying an unreasonable amount of force. On most operators this will be around the middle of the range.

NOTE: For LED location refer to illustration on page 16.
