Dimensions and Description of ACM Titan 240/76 BME mechanism
The central shutter mechanism ACM Titan 240/76 BME is suitable for a Φ76 shaft and can be installed on shutters with a maximum height of 6.0m and a maximum weight of 240Kg. It has a cable for disengagement and manual operation and is suitable for all shutters with springs with external dimensions Φ240 mm.

Installation of ACM Titan 240/76 BME shutter mechanism

- We create a hole at a distance of 5cm from the center of the shaft as shown in the figure above.
- Unscrew the M10 screws from the motor drum
- Then, with an Allen key 6mm, unscrew the two halves (top and bottom) of the motor drum.
- Remove the plastic strip which is the bearing of the mechanism's drum. The plastic strip must be removed carefully so as not to collect dirt, but to keep the grease.
- Unscrew the 4 M8 screws with an Allen key 6mm. Then remove the 2 halves of the motor body.
- Optionally, if required, install the plastic shaft diameter adapter based on the existing Φ10 hole.
- Reinstall the two halves of the mechanism with the 4 M8 screws, which surround the shaft.
- Install the M10 screw into the Φ10 hole we drilled initially, using a 17 mm wrench. This screw has a hexagonal head and no nut. It passes through the shaft to prevent the motor from moving independently of the shaft.
- Place the bearing (plastic strip) back into position carefully.
- Reinstall the two halves of the mechanism's drum with the 2 M8 screws using a 6mm Allen key.
- Install the other M10 screw (which has a nut) and tighten it to secure the motor. Use a 17 mm wrench. Then tighten the "lock nut" to secure the connection.
- Optionally, if required, install the plastic drum diameter adapter.
- Turn the motor to manual operation, holding the disengagement cable. Rotate the drum a full turn manually, in the direction the shutter closes.
- Secure the top part of the shutter curtain (the last slat) to the motor drum. This is achieved by screwing the corresponding M10 screw (C) with its washer onto the thread of the upper half of the motor drum using a 17 mm wrench. If the motor's position does not allow it, pull the motor's cable to bring it to the correct position. (If the curtain has a special part for its connection to the motor, use that and do not drill a hole in the last slat of the shutter).
- Drill the shaft at two points. The two holes are Φ12mm, one for the disengagement cable in case of power failure for manual operation of the shutter and one for the motor power cable. These holes must be smoothed so as not to damage the manual operation cable or the power cable.
- Pass the motor power cable through the first Φ12mm hole we created. The cable must be secured so that it is not damaged during shutter movement. The cable exits from the end of the shaft to be connected. The cable can exit to the right or left of the shaft, wherever it is convenient during installation. Connect the cable (to the 3 contacts of the terminal block and to the motor body).
- In the second hole, place the motor release cable. The cable must be secured so that it is not damaged during shutter movement. Also, the manual operation cable should not fold but should have as small inclinations as possible to function correctly. To pass the cable, the "pine cone" must be removed and reinstalled at the end.
- Check that the motor and the shutter are correctly connected. Also, check that the motor does not allow the shutter to move if we have not disengaged the manual operation. If this is not the case, check the connection of the wire rope to the motor and the path of the wire rope so that it does not have steep inclinations and curves.
- Adjust the limit switch for the closed position of the shutter. Close the shutter. If the drum is on the left (as we look at it), turn the plastic nut (Q1) until it presses the limit switch (1), at which point it will make a slight "click". Now we have set the fully closed position of the shutter.
- Adjust the limit switch for the open position of the shutter. Turn the plastic nut and raise the shutter electrically and observe when it will press limit switch 2 to stop the shutter's movement. It is advisable to do this process hesitantly and in small steps. It is better to make a few more attempts to reach the correct position than to overshoot it by taking large steps. We must be vigilant to stop the shutter's movement ourselves if the limit switch does not stop it.

The connection of the motor to the curtain is shown in the figure below.
The limit switches cut off the power supply to the mechanism when the shutter has completed its travel to the fully open or fully closed position. The limit switches are activated by a black plastic carrier that moves right or left as the shutter moves. The open and closed positions are adjusted by the plastic nuts on the carrier. Depending on the installation of the mechanism (whether the drum is on the left or right), the open and closed position switches are defined accordingly. The figure below analyzes the two ways of installing the mechanism:
