Warning - Potential injury or danger to life！

Warning - Danger to life from electric current!

Note - Important information!

Requirement - Required action!

Schematic representations are based on product examples. Deviations from delivered products are possible.

1. General safety information

   
   

Specified normal use

The drive unit is intented for doors, which have to be secured against falling down; a safety brake is included in the gearbox. The drive unit is directly mounted on the door shaft. The safe operation is only guaranteed with normal specified use. The drive unit is to be protected from rain, moisture and aggressive ambient conditions. No liability for damage caused by other applications or non-observance of the information in the manual. Modifications are only permitted with the agreement of the manufacturer. Otherwise the Manufacturer's Declaration shall be rendered null and void.

Safety information

Installation and initial operation tasks are to be performed by trained, skilled fitters only. Only trained electrical craftsmen are permitted to work on electrical equipment. They must assess the tasks assigned to them, recognise potential danger zones and be able to take appropriate safety measures.

The installation is only to be carried out with the supply off.

Observe the applicable regulations and standards.

Coverings and safety devices

Do not operate unless corresponding coverings and safety devices are fitted/installed. Ensure that gaskets are correctly positioned and glands are correctly tightened.

Spare parts

Use only original spare parts.

2. Technical Data

1) When using a temperature range of +40 celcius - +60 celcius use half of maximum movements per hour.

Caution - Component damage can result!

·The maximum current that can be switched over the limit switch is 1A for 230V AC and 0.4A for 24V DC

3 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

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

Permissible mounting positions

Mounting

Two elongated holes are provided at the gearbox bracket for fastening.

Installation

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

◆ Thoroughly grease the door shaft. 

◆ Install all connection elements according to the specifications of the door manufacturer.

4 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

Remove the cover.	Connect the motor cables and brake cables.	Insert the limit switch plug.

Completing the electrical installation

Mount the cable entires and/or cable glands.

5 Limit switch adjustment

Adjust the limit switches to define the final limits positions for OPEN and CLOSE.

Prerequisite

The door must open when the OPEN pushbutton is operated. If the door closes, L1 and L2 must exchanged with the current switched off.

Adjusting the OPEN limit position

Use the OPEN pushbutton to open the door to the desired OPEN final limit position.

Rotate the cam of the OPEN limit switch S3 to the middle of tappet①.

Tighted the screw of the cam②.

Check the position of the door;

Close the door ① until the cam is free and open the door again ② at OPEN final limit position.

6 Motor connection

7. Limit switch connection

8 Emergency manual operation NHK (emergency hand crank)

The emergency manual operation is provided as a means of opening or closing doors that do not have electric power supply. Operation interrupts the control voltage. Electrical operation is no lpnger possible.

Warning - Injury through improper operation or failing objects!

● Disconnect the voltage

● Adopt a secure position

● For drives that have a brake, emergency manual operation should be carried out with the brakes on

Caution - Component damage can result!

● Do not move the door beyond the final limit positions.

Insert the crank and turn it until it latches(①).

Turn the crank to open or close(②).

The crank can be mounted to the drive unit after usage.

◆ Mounting only as displayed

9 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.

Safety brake in the gearbox

The safety brake is maintenance-free and requires no checking.

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.

Warning - Potential injury or danger to life!

Lifecycle brake - change complete brake unit at:

● Operation with mains supply after 250,000 cycles

● Operation with inverter after 1,000,000 cycles

In an environment that can affect the coefficient of friction of the brake pad (atmosphere with oil, solvents, detergents, etc.), class of protection IP65i must be adopted.

Drive unit

Note!

● Engage a qualified engineer to check the drive unit annually

● Apply shorter inspection intervals for doors that are operated frequently

● Observe the applicable regulations and standards
