• The safety instructions set out in EN 12453, EN 12445, EN 60335, VDE 0100 and ASR A1.7 must be ob-served.

• Work on the electrical installation, the electrical or electronic systems and units may only be carried outby a qualified electrician.

• Assembly may only be carried out by a trained and authorised specialist.

• Before using it for the first time, the door system must be inspected by an expert to ensure that it is in asafe condition.

• Stop the door system and disconnect it from the mains power supply when maintenance and cleaningis being performed either on the system itself or in the immediate vicinity.

• The national fire and accident prevention regulations must be observed. Suitable protective clothingmust be worn when installing the drive.

• All applicable standards and regulations for electrical installation must be complied with.

• Only use spare parts, tools and accessory devices which have been approved by the drive manufac-turer.

• Unapproved third-party products or modifications to the system and its accessories represent a risk toyour safety and the safety of others. This means that the use of unapproved third-party products, ormodifications which have not been agreed with or approved by us, are prohibited. We do not accept li-ability for damage or injury arising from such actions.

• The limits given in the technical data must not be exceeded. The illustrations contained in these instruc-tions are intended as an aid to visualising the product. Therefore, the illustrations may differ from theactual product.

CautionSafety instructions for avoiding serious injuries.• When electrical or electronic equipment and units are operated, certain components are

live. Physical injuries or damage to property can result in the event of unauthorised inter-ventions or failure to heed warnings.

• When installing the drive at a height of less than 2.50 m, the drive must be covered ascontact with the motor could result in burns.

• An adequate clearance distance must be maintained between the drive and combustiblematerials.

• When the switches in the safety circuit are open, the control unit being used must switchoff the drive:- In the case of drives with cam-operated limit switching: safety switches S1F, S2F, S3F,S4F- In the case of drives with absolute value encoders: safety switches S3F, S4F- The connection to the control unit must meet Category 2, PL c.

• The door system must be protected against falling.- In the case of drives for use on roller doors, vertical lift gates, sectional doors and in-directly operated door systems, a suitable mechanism must be provided by the customer(external safety arrester or anti-unrolling device) in order to reliably prevent the leaves/door from falling down in the event of failure of the load-bearing medium (e.g. cables orchains).- In the case of drives with a disconnecting clutch (AK) for use on a sectional door withspring compensation or a counterweight, an anti-drop or spring break safety devicemust be installed to prevent the door from falling down.

4

- In the case of drives with a light chain (LK) or crank handle (HK), it must be ensured thatthe torque acting on the drive is less than the static holding torque stated in the technicaldata should the spring break or counterweight fail. If this is not the case, when usingthese drives the door must be prevented from falling down through the installation of ananti-drop or spring break safety device.- The signal contacts of the external safety device must comply with PL c.

Installation

CautionBefore installing the drive, the driven part must be checked with regard to its mechanicalcondition and to ensure smooth opening and closing.During installation of the drive, access to the danger zone must be blocked off.The drive must be properly mounted on a mounting or torque supporting plate (in accord-ance with the output of the drive) with adequate stability.In the case of directly operated door systems, the drive must be mounted using 4 fasteningscrews M8 (8.8) on a vibration reducing mounting.In the case of indirectly operated door systems, the drive must be mounted using 4 fasten-ing screws M8 (8.8), however should not be mounted on a vibration reducing mounting.The maximum distance between the drive and chain wheel gearing must not exceed 50mm.Assuming a screw-in depth of 10 mm, the tightening torque of the fastening screws for se-curing the drive must be at least 20 Nm and no more than 25 Nm. Failure to observe thismay result in damage to the product or objects in the immediate vicinity.

Once the sectional door has been mounted and properly counterweighted, the door must be counterweighted in every position.The correct counterweight is manually adjusted by opening and closing the door.When installing the drive, always ensure that the drive is protected against soiling (e.g., drilling dust).Before mounting the sectional door drive on the door shaft, the latter must be lubricated in the drive area.

AttentionOnly one of the two feather keys supplied, which is fitted according to the form of the bar-rel, must be used with these drives. After fastening the drive, the feather key must be se-cured from moving using the screw supplied.

Emergency manual operationEmergency manual operation is only intended for commissioning the drive, maintenance work and emergency operation in orderto open or close the door in the event of a short-term power failure. Emergency manual operation is solely intended for manual op-eration.

CautionBefore emergency manual operation is used, the door system must be safely disconnectedfrom the power supply. Emergency manual operation (HK) is only allowed with the motorturned off, via hand crank, and can only be carried out by the service technician or instruc-ted personnel. Emergency manual operation (LK) is also only allowed with the motorturned off.

AttentionEmergency manual operation is not intended for long-term use (e.g. from commissioningof the drive to continuous power supply).Doors with counterweights must be set in such a way that they are fully counterweighted inall positions. If the door is not counterweighted properly, the manual force required is in-creased and the service life of the emergency manual operation mechanism is reduced.

7

(applies to cam-operated limit switching)The door must not be moved beyond the limit positions as otherwise a safety limit switch(S1F/S2F) is activated. If activated, electrical operation of the door system is only possiblewhen the safety limit switch (S1F/S2F) is “released” via emergency manual operation.

3 different systems are available for emergency manual operation:

• Crank handle – HK

• Light chain – LK

• Disconnecting clutch – AK

For each type of emergency manual override system, an appropriate notice (as perEN60335-2-103) must be permanently placed in the vicinity of the corresponding operat-ing element describing how it is to be used. Stickers for use as notices which are appropri-ate to the drive are included within the scope of delivery.

Crank handle (HK)

Operation

Remove the cover by turning it anticlockwise (1.) first, and then lifting it off (2.).

For emergency manual operation, the crank handle is inserted in the motor shaft.

The crank handle must firstly be snapped onto the motor shaft by applying slightpressure (3.) and turning carefully (4.). Following this, proper emergency manual op-eration with the crank handle is possible.

The door can then be opened or closed with the crank handle by turning whilst apply-ing slight pressure.

In order to prevent electrical operation of the door system during emergency manualoperation, the safety switch S3F is opened upon insertion of the crank handle.

Attention! Following operation, the crank handle must be completely removedonce more to allow electrical operation of the door system to resume. Oncethe crank handle has been removed, the cover must be refitted in a clockwisedirection in order to maintain the drive's degree of protection. Make sure thatit clicks audibly into place.

Connection of the chain ends and operation

Connection of the chain ends

Before connecting the ends of the chain using the chain lock provided, it must be en-sured that the chain is not twisted when it is mounted.

The chain lock must be fastened carefully.

10

Operation

  In order to prevent repeated coupling and decoupling of the emergencymanual operation mechanism, the chain must be kept taut during operation.

The door can be opened and closed manually by pulling the respective side of thechain vertically. In order to prevent electrical operation of the door system duringemergency manual operation, the safety switch S3F is activated when the chain ispulled. After operation, ensure that the chain hangs "freely" again so that the safetyswitch S3F is released and electrical operation is enabled once more. It may be ne-cessary to pull briefly on the chain in order to release the safety switch.

Disconnecting clutch (AK)

 Caution! When using drives with a disconnecting clutch (AK) on sectionaldoors with spring compensation or a counterweight, an anti-drop or springbreak safety device must be installed to prevent the door from falling down. Adisconnecting clutch should only be used on sectional doors if the door sys-tem is fully counterbalanced and the drive is not in operation.

Installation of the chain and chain guard

2 chain wheels are supplied with the drive. If the door shaft protrudes well beyond thedrive, you will need to use the small plastic chain wheel. If this is not the case, we re-commend using the larger metal chain wheel.

  Ensure that the coupling bolt (1) is located as far to the left as possible.

Installation of the chain extension

Mount the chain extension supplied with the red handle on the right-hand side wherethe overhang of the chain is short. Accordingly, mount the green handle on the otherend of the chain.

Operation

The drive is decoupled from the door shaft by pulling the red handle (1.). The coun-terweighted sectional door can now be opened and closed manually. Following oper-ation, the drive must be coupled again by pulling the green handle (2.).

  It must be ensured that the lower limit position of the door is set such thatthe cables for suspending the door remain taut, i.e., that the entire weight ofthe door hangs on the cables.

  This guarantees the smooth running of the disconnecting clutch. Incorrectsettings (slack cable) in the lower limit position prevent smooth running of thedisconnecting clutch.

Checking the running directionThe direction of drive rotation depends on the mains connection to the control unit and must be checked first. Proceed as follows:

• Move the door into the semi-opened position using the emergency manual operation function.

• Insert the mains plug of the control unit into the socket or switch the main switch of the control unit on.

• Check that the control unit is in dead-man mode.

• Use the OPEN and CLOSE buttons to verify whether the running direction of the door corresponds to the buttons pressed.If the running direction of the door does not correspond with the button commands, change the direction of rotation as describedin the Assembly and Operating Instructions for the control unit. Then check the running direction again.

Setting the door limit positions

Setting the limit switches for drives with cam-operated limit switchingThe drive comes with 6 cam-operated end switches as standard. All cams have 12 lock-in positions for quick adjustment. Checkthat the control unit is in dead-man mode.Proceed as follows to set the limit switch:

1. Turn all 6 cams out of the movement range of the door.

2. Use the DOWN button of the control unit to move the door to just before the lower limit position.

3. Rotate the black cam S6 "CLOSE" on its shaft until the precision set screw is within easy reach. Now use the precision setscrew (slotted) to manually set the cam in such a way that it activates the switch. Move the door slightly up and down again un-til the end switch stops the door. Fine tune the setting as necessary.

4. Now move the door to just before the upper limit position.

5. Now set the grey cam S5 "OPEN" in the same way as described in point 3.

6. Now set the yellow safety cams S1F "UP" and S2F "DOWN" to lag both operational limit switches S5 "OPEN" and S6 "CLOSE".

7. The two functional cams S7 (orange) and S8 (green) can be set accordingly if required.

8. The limit switches are now set. Carry out a test run to check the set limit positions.

If the orange functional cam S7 is used as a pre-limit switch for functional switch-off of thesafety edge of the door, then it must switch a maximum of 5 cm above the floor; EN12453and EN12445.

Replace the housing cover on the limit switching system. Make sure that the seal and the lining groove are clean and that the coveris properly positioned. Tighten the screws carefully.

Setting the limit switches for drives with absolute value encodersThe drives are equipped with an absolute value encoder with which the control unit recognises the door’s limit positions.

AttentionThe absolute value encoder cannot be set in the drive.

The door limit positions are set directly in the control unit. Follow the Assembly and Operating Instructions for the control unit.When you close the housing cover of the limit switching system, make sure that the seal and the lining groove are clean and thatthe cover is properly positioned. Tighten the screws carefully.

Maintenance

AttentionThe door system must be regularly checked by an expert to ensure that it is in safe workingorder. The door manufacturer stipulates the frequency of maintenance and checks ac-cording to national regulations and the frequency of use.

Counterweight (applies to sectional doors with spring compensation or a counterweight):The counterweight/spring tension must be checked. The sectional door should be counterweighted in every position. Note thedoor's operating instructions.

The following checks must be performed on the drive:1. Fastenings:All fastening screws, including the screws to secure the torque bracket, must be checked to ensure they are in good condition andfastened securely.2nd Safety limit switches:The functionality and switch-off point of the safety limit switches S1F, S2F and S3F must be checked. Follow the relevant assemblyand operating instructions for the door control unit. The safety limit switches must be checked for continuity as per the connectiondiagram.Re S1F / OPEN (applies to cam-operated limit switching)Open to the upper limit position. Using the emergency manual operation function, keep opening up to the point where no damageoccurs. The safety switch S1F must be checked as per the connection diagram. There must be no continuity.Re S2F / CLOSE (applies to cam-operated limit switching)Close to the lower limit position. Using the emergency manual operation function continue closing until the load-bearing medium(e. g., cables or chains) for suspending takes the complete weight of the door sections. It must be ensured that the cables do notfall from the cable drum. The safety switch S2F must be checked as per the connection diagram. There must be no continuity.Re S3F (applies to HK and LK drives)Before inspecting the safety switch S3F, the door system must be disconnected from the mains.Insert the crank handle (HK) in the motor shaft and turn through at least one revolution and hold the position or pull the light chain(LK) and keep it taut.The safety switch S3F must be checked as per the connection diagram. There must be no continuity.3. Gears:The gears are lubricated for life and maintenance-free.4. Toothed belt

1. Check that the toothed belt (1) has sufficient preliminary tension.

2. Carry out a visual check of the toothed belt (1) along the complete travel distance of the door. The toothed belt (1) must showno signs of wear.
