CLEAR-A-VIEW GLAZED ROLL-UP INSTALLATION INSTRUCTIONS WARNING
B&D Doors recommends that locks are not used on motorised doors. Damage may be caused to the door or the drive unit if activated whilst the door is locked. NOTES FOR GENERAL USE This unit has a low cycle motor and should only be run continuously for three minutes every twenty minutes. If this is exceeded, the thermal overload may activate, and a cool down period of fifteen to thirty minutes will be necessary. The slot in the ceiling needs to be a minimum of 76mm to clear potential bow in the curtain. When the shutter is closed, the motor is exposed. If fitting onto the face of a building, a cover with a bottom return would be required for security and weather protection. (Cover supplied by others) Installation – There has to be good access (i.e. a straight lift up into position) with the shutter to be fixed to steel posts, steelwork, concrete or core-filled blockwork only. There must be removable access panels 600mm wide for the full length of the drum and shaft. Steel posts of 75x75 RHS are required to support the door. The capstan wheel must be used to tension the door correctly. The system is operated by means of a spring return key switch mounted inside, outside, or both if required. Auto reverse is not available, as the door should travel the full distance, up or down, prior to being reversed. The manual release cable should not be bent excessively, as its performance is degraded with bending. The manual release handle must be mounted so that it is accessible if a power failure is experienced. This responsibility lies with the shop fitter or shop owner. If this motor is connected to any other system (i.e. not using the spring return key switch supplied by B&D Doors) an Auto Delay System must be implemented.
CLEAR-A-VIEW GLAZED ROLL-UP INSTALLATION B&D Doors recommend that these instructions are kept with the door
IN THE EVENT OF A POWER FAILURE STEP 1. If door is open, ensure doorway is unobstructed. When the manual release is activated, the door can descend quite quickly, resulting in a “Guillotine” effect. STEP 2. To locate manual release cable: Manual release cable (pictured) should be located at the same end of the door as the power supply. B&D recommends the use of an access hatch at no higher than shoulder height (around 1.5m off ground) to store manual release handle.
MANUAL RELEASE HANDLE & CABLE
STEP 3. To activate manual release: Activate manual release by holding the upper section of the release handle firmly, and screwing the lower section of the handle in a CLOCKWISE direction looking from the top of the handle. When door operates freely, this confirms that the manual release is activated. WARNING! Activating the manual release while the door is up may allow the door to descend rapidly. Ensure operator and all other personnel are clear of door operational areas. STEP 4. To operate door manually: Door is now able to be manually operated. To hold door in place at a required height, lift the door to the required height and deactivate the manual release. To secure door while it is closed, simply deactivate the manual release. STEP 5. Resumption of power supply: When power is returned to the site, make sure the manual release is deactivated and that the door is in the closed position. The door should now operate in a normal fashion. SETTING CLEAR-A-VIEW LIMIT SWITCHES STEP 1. Ensure both limits are covered by pushing both red end caps toward each other (diagram 1) STEP 2. Rotate the white rotors out until they are touching each red cap (diagram 2) STEP 3. Run the door up and down once only STEP 4. Mark the position of each white rotor with a pen STEP 5. Pull back both red caps to expose the limits (diagram 3) STEP 6. Rotate each white rotor one revolution towards its red cap (diagram 4) STEP 7. Test the door to ensure correct operation; small adjustments may be necessary
CLEAR-A-VIEW GLAZED ROLL-UP DOOR INSTALLATION INSTRUCTIONS The enclosed installation instructions are issued as a guideline only, and may not necessarily be applicable for every site application. B&D Doors is not responsible for incorrect preparation of openings to suit its products, nor is responsible for non-compliance to the recommendations enclosed. The installer is responsible for correct installation and operation of the B&D Doors product. If in doubt seek clarifications from B&D Doors prior to proceeding with the installation.
THESE INSTRUCTIONS ASSUME A RIGHT HAND STANDARD MOUNT MOTOR STEP 1. Refer to Column Details on page 5 of this booklet. Measure the opening width, “Front-to-Front” of guide. STEP 2. To determine the guide “Back-to-Back” opening width, add 172mm to the “Front-to-Front” opening width. If using Alternative 1 for column details, add extra 80mm to allow for timber packer. STEP 3. Bolt or weld 75mm x 75mm fixing angles to square RHS 75mm x 75mm column, with at least 35mm of the angles in contact with the column (See Diagram 1). Centre hole recommended 420mm above bulkhead line, minimum 320mm. Centre hole to underside of shaft is 35mm (See Diagram 2).
STEP 4. Mount motor mounting brackets onto fixing angles at both ends using M16x40 bolts. Attach the clamp bracket angle to the motor bracket in the appropriate position according to the bundle diameter. For doors more than 3000mm in height, use rear position. For doors between 2100mm and 3000mm high, use middle position. For doors less than 2100mm DIAGRAM 2 in height, use front position. Attach the capstan bracket angle to the opposite side of the motor mounting bracket so that it will lie beneath the capstan bolt-hole (See Diagram 2). The capstan bracket angle may need to be attached to the motor mounting bracket after tensioning, depending on clearance for the tensioning rod. STEP 5. Lift drum using 2 chain blocks, duct lifter, crane/forklift (or other suitable method). Fit ‘U-Bolt’ clamps onto the clamp bracket angle and loosely tighten around the shaft of the drum. (See Diagram 4)
DIAGRAM 3 STEP 6. TENSIONING 3
The roller shutter can be tensioned two ways; using the motor or manually using the capstan wheel. MOTOR TENSIONING Prior to attaching the curtain, plug the motor into a temporary power supply. Stop the shaft from rotating by tightening the U-bolt clamp and by dropping a M12x75 bolt through the capstan bolt hole and tighten to the capstan bracket angle with a M12 nut. Turn the motor ‘down’ (in the direction shown in diagram 4) approximately 5 full revolutions or until the desired tension is reached. (As a rule of thumb, tensioning requires 1 full rotation for every meter of opening height, + 1). For example, a 4m high door requires 4+1=5 rotations.) Attach the curtain to the drum as per STEP 7. MANUAL TENSIONING Attach the curtain to the drum as per STEP 7 and activate manual release cable so that drum rotates freely. Turn capstan wheel (in the direction shown in diagram 4) approximately 5 full DIAGRAM 4 turns or until the desired tension is reached. Place a M12x75 bolt through the capstan wheel and tighten with a M12 nut to the capstan bracket angle. Check tension by manually operating door and adjust as required. Once tensioning is complete, disengage manual release cable. STEP 7. Lift curtain to drum using a lifting device (duct lifter or equivalent) and a cradle. Cut packing if necessary. Using a lifting device, take curtain up until the top slat can be hooked onto the 20x20 RHS on the drum. Secure the top slat to the 20x20 RHS with self-tapping screws no less than 800mm apart. Curtain is now in fully closed position. STEP 8. Drive the curtain up to the open position, checking it is tracking straight. STEP 9. Flare the top of the side guides and fix to column / wall. STEP 10. Drive door down to the closed position and set upper and lower limit switches. STEP 11. Check operation of the door and make any final adjustments. STEP 12. The installation of the keyswitch and if applicable the Battery Backup Unit (UPS), and the final check of the limit switches are to be carried out by a qualified electrician.
