GFA KE 120.24-5500 Elektromat Safedrive

General safety information

Specified use
The drive unit is intended for vertically moving doors. The force is transmitted using a chain. Doors that must be secured against dropping require a separate safety brake. The drive unit must be protected against moisture and aggressive environmental conditions (such as corrosive substances). The drive units are only suitable for indoor use. Appropriate protective measures must be taken for outdoor installation. The drive unit is not intended for hazardous areas. The values specified in the technical data of the drive unit must not be exceeded. The safe operation can only be ensured if used as specified.
Target audience of these installation instructions
These installation instructions are geared towards qualified persons trained in the handling of door systems. Expert knowledge, relevant skills and practical experience are what set apart qualified persons. They are capable of safely carrying out the tasks involving installation, maintenance and modernisation according to the instructions.

Safe operation
The safe operation of the product can only be ensured if it is used as specified. Follow the installation instructions. Observe all specifications, especially warnings, when installing the product in the overall system. GfA is not liable for damage resulting from non-observance of the installation instructions. The resulting overall system must be reassessed for its safety in accordance with applicable standards and directives (e.g. CE marking). These installation instructions refer only to a part of the overall system and are not sufficient as the sole instructions for the overall system. The installer of the system must prepare the instructions for the overall system. We recommend entering the danger area of the system only when the drive unit is at a standstill.

Warning – Failure to follow these installation instructions may result in severe injury or death.

• Please read these instructions before using the product.
• Keep these instructions handy.
• Include these instructions when passing on the product to third parties.
• Do not let children operate the product unsupervised or use as a toy.

Mechanical installation

Prerequisites
The permissible loads on walls, fastenings, mountings and transmission elements must not be exceeded, even for maximum holding torques or locking torques (▶ refer to technical data).

Connection elements

1. Self-locking connection elements with a minimum strength of 800 N/mm2 (8.8) must be used.
2. Utilize the hole diameter to the full.
3. Use adequately dimensioned washers for elongated holes.

Permissible mounting positions
Transmission elements

1. Install the chain wheel properly.
2. Position the chain wheels properly.
3. Tighten the chain wheel properly.

Mounting
Four elongated holes are provided for mounting. Mount the supplied support angle on the side of the sprocket.

Installation

The descriptions below apply to general door specifications. The specifications of the door manufacturer must also be observed during installation.

1. Thoroughly grease the output-shaft.
2. Install (①) and secure (②) the chain wheel. Do not tighten yet. Install (③)and secure (④) the output-shaft on the right or left.
3. Mount the drive unit. Tighten the connection elements to 170 Nm.
4. Position the chain wheel (①) properly. Install the chain wheel (②). Secure the chain wheel (③).
5. Tighten the chain wheel properly (①). Tighten all connection elements (M16) to 170 Nm (②). Install all other connection elements according to the specifications of the door manufacturer.

Electrical installation

Warning – Danger to life from electric current!

• Switch the mains OFF and check that the cables are de-energised
• Observe the applicable regulations and standards
• Make a proper electrical connection
• Use suitable tools

Performing electrical installation

1. Remove the cover.
2. Insert the motor plug.
3. Insert the limit switch plug.

Completing the electrical installation

Limit switch setting

The setting of the final limit positions OPEN and CLOSE is described in the instructions for the door control.

The door control must meet Performance Level c!
Use only door controls that evaluate the limit switch according to EN 12543 and meet Performance Level c. Mount the cable entries and/or cable glands.

Motor connection

Alternative motor connection
Limit switch connection

Emergency manual operation (hand chain operator)

Emergency manual operation is designed for opening or closing the door without power supply. Its activation interrupts the control voltage. Electrical operation is no longer possible.

Warning – Injuries due to incorrect operation!

• Switch off voltage.
• Adopt a secure position.
• For drive units with brake, the emergency manual operation must be carried out against the closed brake.
• Adopt a secure position.
• For drive units with brake, the emergency manual operation must be carried out against the closed brake.
• Do not move the door beyond the final limit positions.

Switch on by pulling the red handle. Open or close by pulling the chain. Switch off by pulling the green handle.

Completing commissioning / inspection

Check the following components and then install all covers.

Gearbox
Check the drive unit for loss of oil (a few drops can be neglected). Protect the output-shaft permanently against corrosion.

Mounting
Check that all connection elements (consoles, torque mounts, screws, locking rings, etc.) are secure and in proper condition.

Electrical wiring
Check the connection cables and cabling for damage or crushing. Check that the screw connections and plug connections are fitted properly with a good electric contact.

Emergency manual operation
Check the function with the power disconnected. Perform the check only between the final limit positions.

Limit switch
Check the final limit positions by opening and closing fully. The safety area must not be approached.

Brake

Warning – Potential injury or danger to life!

• Carry out a brake test. Overrun depends on the door and its equipment. The specifications of the door manufacturer must be observed.
• Brake lift may only be used in the final limit position CLOSE for doors that have no counter-balancing.
• Operation with mains supply after 250.000 cycles
• Operation with Inverter after 1.000.000 cycles
