My opener/closer has started beeping and has a blue flashing light on it. What does this mean and what do I need to do now?

    This means that the battery needs charging.  The door will now be in the open position and you should disconnect the battery and give it a full charge. When charging your battery, the indicator light on the charger should start off being red, then turn to green when it is charged. Please do not remove the battery before it is fully charged.  

    Check that the solar panel is well positioned to get plenty of daylight and that it's blue light is flashing regularly. This indicates that it is generating power.

    When reattaching the battery, the motor appears to be trying to continue pushing/pulling the door when at the end of its travel (for arm-operated Hentronix units)

    First, disconnect the battery and put the split pin back to connect the door to the arm.  Then, using a 13mm or adjustable spanner, turn the brass connector at the motor end of the thread until the door is about half open (mid position).  It's a bit slow and tedious doing this but it allows everything to reset.

    Then, reconnect the battery.  The blue LED should light for 1 second, then there is a short pause, then it will either open or close depending on where it left off previously. If it is daytime it should either open and stay open until dusk, or it will close and then open after one minute.

    Once I connected the battery, the door moved for a short while then stopped before it had reached the end/the door isn't moving

    For externally-mounted sliding doors, it's always important to double check that the screws that fix the door footing to the door aren't poking out on the back of the door - occasionally even the tip of a screw can jam the door.  Sometimes the door seems to slide perfectly when disconnected from the arm, but snags on the tip of a screw when in operation. 

    If the screws are poking out of the back of the door and are snagging, using slightly smaller screws or putting one or two 4mm washers under the screwhead will fix this problem.
