Once the installaon of the opener and controller is complete it is me to test the operaon. Make sure the door is away from
the ground or the top door stops (mid open posion). This will prevent damage to the door in the event that the door direcon is
reversed in relaon to the controller (see below changing door direcon).
Checking power
Ensure the unit is powered by checking that the POWER ON
indicator on the controller is lit.
If a Key Switch variant is installed, ensure the key posion is
ON or MAN.
You should also noce that the LIMIT ERROR indicator
(orange) is lit which signies that there are no limits set.
Door direcon
Check the direcon of the door movement. If the direcon of the door is incorrect, refer below to Changing door direcon.
Changing door direcon
To change the door direcon rst put the unit into ‘limit seng mode’. To do this:
1. While holding STOP, press the SET buon 3 mes.
The LIMIT ERROR indicator will start ashing signifying ‘limit seng mode’
2. Press and hold STOP for 10 seconds unl the LIMIT ERROR indicator ashes quickly.
The direcon of the door movement will now be reversed.
The LIMIT ERROR indicator will remain ashing as the unit is sll in limit seng mode. You can now set limits (go to step 2 on
