3. General safety advice

Manual for installation and operation, Comfort 220, 250, 252 GB (#78335) 5

Information on installing the operator system

• Ensure that the door is in good mechanical condition.

•

Ensure that the door can stop in any position.

• Ensure that the door can be easily moved in the OPEN and CLOSE directions.

• Ensure that the door opens and closes properly.

• Remove all unnecessary components from the door (e.g. cables, chains, brackets).

• Render any installations inoperable that will no longer be needed after the operator system has been installed.

• Before commencing cabling works it is very important to disconnect the operator system from the electricity supply.

Ensure that the electricity supply remains disconnected throughout the cabling works.

• Adhere to the local protection regulations.

• Lay the electricity supply cables and control cables; these MUST be laid separately. The controls voltage is 24 V DC.

• Install the operator system with the door in the CLOSED position.

• Install all the impulse transmitters and control devices (e.g. remote control buttons) within sight of the door and at a

safe distance from the moving parts of the door. A minimum installation height of 1.5 m must be observed.

• Permanently fix the warning signs, which advise of the danger of becoming trapped, at conspicuous locations.

• Ensure that no part of the door extends across public footways or roads when the installation is complete.

Information on commissioning the operator system

After initial operation, the persons responsible for operating the door system, or their representatives must be

familiarised with the use of the system.

• Make sure that children cannot access the door control unit.

• Before moving the door, make sure that there are neither persons nor objects in the operating range of the door.

• Test all existing emergency command devices.

• Never insert your hands into a running door or moving parts.

• Pay attention to any parts of the gate system that could cause crushing or shearing damage or accidents.

The EN 13241-1 regulations must be observed.

Information on servicing the operator system

To ensure proper operation, the following items must be checked regularly and repaired if necessary.

Before any works to the door system are undertaken, the operator system must be disconnected from the mains.

• Check once a month to ensure that the operator system reverses if the door encounters an obstacle.

Depending on the operational direction of the door, place a 50 mm high/wide obstacle in its path.

• Check the settings of the OPEN and CLOSE automatic cut-out function.

• Check all movable parts of the door and operator system.

• Check the door system for signs of wear or damage.

• Check whether the door can be easily moved by hand.

Information on cleaning the operator system

Never use water jets, high pressure cleaners, acids or bases for cleaning.

Please read carefully!

6.2.1 Mounting in line

• Place the drive boom (C) in the correct position on

the adapter sleeve (A).

• Applying slight pressure, lower the drive boom (C)

onto the motor unit (F).

Tip:

element (chain drive, toothed drive belt

or ball chain) is sufficient to lower the

drive boom.

• Position the boom clamps (F) on the drive boom (C).

• Screw the boom clamps (F) to the motor unit using

the four screws (E).

6.2 Installing the motor unit and

drive boom

• Push the adapter sleeve (A) onto the gear shaft (B) as

far as it will go.
