Need help?Do you have a question about the Alutech Targo TR-3531-230 and is the answer not in the manual?
The ALUTECH Targo TR-3531-230/TR-5024-230 electromechanical shaft-type drives are designed for the automation of balanced sectional industrial doors, intended for use with an external control unit. The drive features an electric motor and a self-locking gearbox. Control of the drive's final stop positions is achieved through mechanical switches and cams, which offer both coarse and fine adjustment. In the event of a temporary power outage or during door maintenance, an emergency manual control system, utilizing a chain operation facility, allows for manual movement of the door leaf. Additionally, a manual release mechanism provides another option for manual operation.
All technical specifications are valid at an ambient temperature of +20 °C (±5 °C).
The drive should only be installed and operated by qualified specialists. It is crucial to ensure that the door structure is robust, suitable for automation, and allows for easy and uniform movement of the door leaf. The door leaf must be balanced, remaining immobile in any position when released. The installation site must comply with the specified temperature operating range. The drive cannot be used with doors that have an in-built wicket door unless a blocking mechanism is in place to prevent drive operation when the wicket door is open. Sufficient space around the drive must be ensured for easy and safe manual release. The drive and its components must be kept at a safe distance from heat sources or open flames. The mounting surfaces for the drive system and its components must be strong and rigid. Foreign objects, water, or other liquids must not be present inside the drive; if found, the drive must be disconnected from the mains and serviced. The electrical network must be equipped with protective earthing and a short-circuit protection device. Cables should be protected from rough or sharp surfaces, using corrugated tubes, pipes, and cable ducts. Control cables must be laid separately from mains voltage cables. No electrical connections should be made while laying cables; ensure the wiring is de-energized.
Mounting should be performed with the door closed. The drive can be positioned to the right or left of the door, and its operating position can be horizontal, vertical, or at a 45-degree angle. The manual provides an example of vertical mounting. The drive must be released before mounting on the door shaft. The mounting bracket can be installed on either side of the drive. After positioning the drive and marking the mounting holes, the drive is removed, and the bracket is secured to the substrate. A locking ring is placed on the door shaft, then the drive is inserted, and a key (for solid or hollow shafts) is installed. The mounting bracket is then secured, and all screws are tightened. A second locking ring is placed on the shaft, tightened against the drive, and secured with screws. Finally, the drive is locked.
In emergency situations (e.g., power failure or repairs), the chain operation allows manual opening and closing of the door. To activate, pull the cord with the red handle until it stops. Pulling the chain loop will raise or lower the door. To return to powered operation, pull the cord with the green handle until it stops. The drive must be disconnected from the electrical mains when using chain operation. This feature is not for frequent use. The chain must be properly assembled with special links, and its lower edge should be at a height of 0.5-1.5 meters. The chain must never be twisted. To prevent entanglement and obstruction, the lower part of the chain should be fixed at approximately 1.5 meters, and the chain should hang freely without tension.
The manual release is for trained personnel only and should only be used when the door is closed and the drive is disconnected from the mains. Uncontrolled door movement can occur if springs are weak or broken, or if the door is unbalanced. Move the released door leaf at a moderate speed. To release the gearbox, turn the release lever from the ON to the OFF position (90 degrees). To re-engage, reverse the action and return the lever to the ON position.
The electric motor connection cable and the switch cable are pre-connected to the drive. Wires should be connected to the external control unit according to the provided markings and their purpose (e.g., CL.L for CLOSE, OP.L for OPEN, SW1/SW2 for auxiliary switches, L1/L2 for phases, COM for common phase contact, YE-GN for protective earthing). After connecting, verify the correct direction of door movement from the intermediate position. If the direction is incorrect, adjust it according to the control unit manual.
The door's closing and opening positions are adjusted manually by regulating the final position cams. To access the cams, remove the drive cover by unscrewing six screws. Each cam has a locking screw (H) and a fine adjustment screw (I). The locking screw fixes the cam, and the fine adjustment screw allows for precise adjustment.
After mounting, connecting, and adjusting, ensure all safety rules and manual requirements are met. Verify that the drive is securely mounted and that all covers are replaced. Release the drive, manually open and close the door several times to confirm balance and smooth movement, then re-engage the drive. Perform a full "open-close" cycle using the control unit, checking for correct movement direction and smooth stopping at final positions. Commissioning involves:
