18 - TROUBLE SHOOTING10THE RED ERROR (ERR) LED TURNS ON, AND THE CONTROL UNIT DOES NOT FUNCTION- Repeat Automatic Gate Travel Learning – see section 9-The control unit is in Safety Test mode (section 14) to deactivate:- Faulty control unit – replace the unit- Memory hybrid fault - replace the boardGATE DOES NOT MOVE AT ALL- check that the control box has power.- Check the main fuse. IMPORTANT: TURN OFF POWER BEFORE CHECKING THIS FUSE- Verify that the STOP (ST) LED is on. If not check connection on the STOP input (terminal 14).This is a Normally Closed contact.- Check that the remote control is programmed for the system (Section 5)GATE OPEN BUT NOT CLOSE- Check that the photo sensors are properly connected (PHO LED is on). If the LED is off ensure thatthe photo-sensors are connected properly and that nothing is blocking the beam’s path.- Check that the green START LED is off. If it is on then check connection to the START input (terminal 12).This is a Normally Open contact.- Check photo red LED to be on, if not check the link (jumper) or the photo 2 connectionTHE REMOTE CONTROL DOES NOT WORK- Check that the LED on the remote is working. If not replace the remote’s batteries.- Check that the red RADIO LED briefly flashes when the remote transmits. If it does not thenre-program the remote.GATE CLOSES BY ITSELF (WITHOUT THE REMOTE BEING PRESSED)- Check the operation mode – DipSwitches 2 ON , DipSwitch 3 OFF >> Step-By-Step mode- Check that DipSwitch 7 (Close after Photo) is OFF.GATE STOPS HALFWAY AND THEN MOVES IN THE OPPOSITE DIRECTION- The obstacle sensitivity is too low: Increase the Obstacle Sensitivity Potentiometer.- Check that the gate does not cut the photo sensor beam when moving.- Open the manual override and check that the gate travels freely all the way.- repeat Automatic Gate Travel learning (section 9)GATE STOPS HALFWAY- Not enough force; Increase the POWER potentiometer. Adjustment to this potentiometer will alsochange the speed and will require repeating the Automatic Gate Travel Learning (Section 9).- The gate stops after they reach the slow down point. Manually set (or remove the slow down)points (Section 10).SHORT RECEPTION RANGE- The remote control batteries are weak or dead. Replace batteries.- An external antenna needs to be added to the system.NOTE: External interferences from power lines and other emitting devices can influence thereception range. Installing an external antenna may improve the reception range.GATE IS NOT TIGHTLY CLOSED WHEN REACHING THE CLOSED POSITION- Increase the Obstacle Sensitivity potentiometer so that the wings are pressing harder against the stopper.- Check that all brackets and hinges are secure and that their bolts are tightenedTHE MANUAL RELEASE IS JAMMED- The override mechanism is too tight. Decrease the Obstacle Sensitivity potentiometer.- It is recommended to repeat the Automatic Gate Travel Learning after adjustment to this potentiometer
