We strongly recommend that a set of safety infra red beams (ET BLUE I’s) be used for additional protection. DO NOT operate the Garage door operator while a person, especially a child is near the door. Children must be under adult supervision at all times near an automated garage door especially whilst the operator is in use. Ensure that the BUILT IN SAFETY OBSTRUCTION SENSING SYSTEM (Load sensing) is correctly setup. Regular testing (Monthly) is advised and adjustment must be made if necessary.
PRE-INSTALLATION INSTRUCTIONS 1. PRE-INSTALLATION PREPARATION 1.1. Ensure sufficient side room space: Minimum side room of 85mm from the face of the door drum wheel to the inside edge of the door support bracket is required to install the opener (see Fig. 1) and maximum side room is 125mm before having to move and re-fit the support bracket or install the drive unit fully inside the drum (Fig. 7) 1.2.
INSTALLATION INSTRUCTIONS WARNING: EXTREME CARE SHOULD BE TAKEN TO PREVENT ANY POSSIBLE DAMAGES 2. INSTALLING THE OPENER ONTO THE DOOR SHAFT There are various methods on how to install an opener to the door. The following is the most typical method. CAUTION: THE INSTRUCTIONS SHOWN HERE ARE FOR RIGHT-HAND INSTALLATION 2.1 Roll the door up until the door curtain is out the door guides / tracks and use a rope to firmly tighten the roll in the middle of the door (see Fig. 3). 2.
2.5 Switch the opener into manual operation mode by pulling the manual release handle to enable the opener drive to rotate freely. 2.6 Raise the door carefully, insert the opener into the door axle and ensure the two opener forks hold the door drum wheel support. Push the opener inside the door roll as deep as possible (Fig. 4). In cases where the drum spokes do not match the drive fork, fasten a block of wood or similar material to the drum that will hold firm when driven. (Fig 6).
PIN DOOR CURTAIN TO DOOR DRUM WHEEL 3.1 Pinning the door curtain to the drum wheel will reduce possible forced lifting of the door. Close the door to the fully closed position and mark the two positions where the curtain is to be pinned onto the drum wheel on either side of the door. The marked positions (pinning locations) should be at least 90o apart (see Fig. 8). 2.1 Raise door a little so that you can access the marked positions and pin curtain to drum wheel with self-drilling tech screws or rivets.

CONTROL CARD FEATURES AND SETUP EXPANDED A. Auto-close link: Placing a jumper across these 2 pins will cause the door to close automatically after 20sec. from any open position. Before closing the unit will emit three warning beeps. The door can still be triggered to close manually before 20sec. has counted down. B. Receiver programming pins: Max BT (Button trigger function) = 25 locations. Max L (Light function) = 6 locations.
H. Motor output fuse: If blown replace with an 8A fast blow fuse only. This fuse will normally blow if the maximum resistive load (Heavy door action/obstruction) is exceeded. I. Battery low beep override jumper: If the unit has been installed without batteries, place the jumper across the pins here. The unit will no longer beep once every 16 seconds. NB! When batteries are installed the battery low beeps must be active! Advanced onboard receiver features. 7.
Adjusting the open and closed limit positions: Fig. 14 Fig. 15 Accessing the limit switches Loosen the limit cams Fig. 16 SETTING THE DOOR TRAVEL LIMITS. A: RIGHT-HAND SIDE INSTALLATION. Remove the back cover from the opener (Fig 14). Pull the manual release handle to change opener to the manual operation mode. 8.1 Open Limit: Raise the door manually to the open position you would like it to stop at.
8.3 Slightly re-tighten the two wing-nuts 8.4 Power controller up by connecting the mains power first and then the battery leads 8.5 Pull the manual release handle to change the opener back to automatic mode. Testing and adjusting travel limit settings (RIGHT-HAND fit): 8.6 Close position: Press and release the onboard test button. If the door does not stop at the pre-set closed position, repeat step 6.3 above. Turn the closed limit cam anti-clockwise to raise the closed position or clockwise to lower it.
GENERAL MAINTENANCE: 10 The following should be conducted MONTHLY 10.1 Safety reverse test. Repeat the test (see F control card features) and make adjustments if necessary. 10.2 Door manual operation test. Manually open and close the door. Check to ensure door is not too heavy or over tensioned, difficult to close (should be less than 15kg operating force in general), unbalanced or binding due to loss of tension in the spring. 10.3 Check door is not pulling or pushing askew in the guide tracks thus binding.
