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.

Danger to life from incorrectly installed transmission elements
A chain with too little or too much tension may skip or break. As a result, parts of the door structure may
become loose and drop. The drive unit or door construction may also suffer damage.
Note the information given below on the selection and use of transmission elements.
Grease the output shaft and key thoroughly. Use
suitable assembly grease.
Mount the sprocket (①). The hub side of the
sprocket points away from the drive unit. The
sprocket must lie fully over the key.
Tighten the fastening screw slightly (②).
Mount the drive unit.
Tighten the fastening screws slightly.
Mount the chain.
The sprockets of the drive unit and door must be
flush.

Tighten the fastening screw of the sprocket.
Tension the chain. The slack side (Ⓐ) must not
exceed the height of a chain link (Ⓑ).
We recommend using a chain tensioner.
From an angle of 60°, a chain tensioner is required
in the slack side.
Tighten all fastening screws.
Also note the specifications of the door
manufacturer.

7Electrical installation
General information
WARNING
Danger to life from electric shock!
Improper wiring may result in severe or fatal injury from electrical current.
Allow only competent people to carry out the work.
Disconnect all cables from the power supply.
WARNING
Danger to life from uncontrolled movements!
Unauthorised switching on of the voltage during assembly and maintenance may lead to injuries as a result of
uncontrolled movements.
Secure the mains supply against being switched on or plugged in again.
WARNING
Danger to life from uncontrolled movements!
Failure of a phase in the motor supply line may lead to uncontrolled movements of the drive unit.
Use fuse protection with an all-round switching circuit breaker with C characteristics.
WARNING
Danger to life from falling parts.
If the motor fails to switch off, the door could overrun the final limit positions. This may lead to a hazard from
falling components.
Use a door control that complies with the EN ISO 60335-1.

Mechanical limit switch - function
Cams S1 - S6
Use cams S3 and S4 to specify the final limit positions OPEN and CLOSE of the door.
The cams S1/S3 and S2/S4 are mechanically linked. The emergency limit switches S1 and S2 only switch when
the drive unit moves beyond the final limit positions OPEN and CLOSE. The emergency limit switches are
automatically preset with the final limit positions. An actuated emergency limit switch interrupts the safety circuit.
The drive unit switches off.
You can use the auxiliary limit switches S5 and S6 individually through terminals X12.11-13 and X12.14-16 (see
the circuit diagram of cam limit switches).
Terminals 4 to 9: safety circuit
Terminals 4 and 9 form the safety circuit. If the safety circuit is interrupted, the drive unit switches off. Terminals
21 to 26 are factory-fitted with wire links. Instead of the wire links, you can connect additional safety devices
(e.g. safety brake). Terminals 27 and 28 are used for the thermal protection of the motor.

Mechanical limit switch - setting the final limit position
The following explains how to set the limit switch and thereby specify the final limit positions OPEN and CLOSE.
Check the output rotating direction
Issue an OPEN command.
If the door opens, the output rotating direction is
correct. Continue with setting the final limit position
OPEN.
If the door closes, the output rotating direction is
wrong. Change the output rotating direction before
setting the final limit positions.
Setting the output rotating direction
If the movement direction of the drive unit does not correspond to the movement command, you can change the
rotating direction. If you use a GfA door control, change the output rotating direction by using the programming.
Follow the instructions for the door control. Otherwise change the output rotating direction as explained below.
WARNING
Danger to life from electric shock!
Improper wiring may result in severe or fatal injury from electrical current.
Disconnect all cables from the power supply.

16
Disconnect all cables from the power supply.
Swap L1 and L2 in the supply line.
Then switch the voltage back on.
Setting the final limit position OPEN
Remove the limit switch cover of the drive unit.
Issue an OPEN command until the door has
reached the desired position.
Turn cam S3 to the centre of the switch.
Tighten the screw for coarse adjustment with the
enclosed key.
Check the set position by closing the door until the
cam no longer touches the switch. Then move to
final limit position OPEN.

17
The final limit position OPEN can be corrected by
fine adjustment.
Check the door position after a correction.
Checking and correcting the emergency limit switch OPEN
Setting S3 will automatically preset the emergency limit switch S1. Check whether the preset distance is
sufficient.
WARNING
Danger from falling objects!
If a limit switch does not switch, the drive unit is stopped by the emergency limit switch. If the emergency limit
switch switches too late, the door can be damaged or parts of the door leaf may come loose.
Set the emergency limit switch.
A fixed stop of the door leaf may reduce the danger.
Turn the screw for fine adjustment on cam S1 until
the door stops without risk even when passing the
final limit positions.
Setting the final limit position CLOSE and auxiliary limit switch
Proceed as for setting the final limit position OPEN.

11 Maintenance
WARNING
Danger to life from electric shock
Improper wiring may result in severe or fatal injury from electrical current.
Allow only competent people to carry out the work.
Disconnect all cables from the power supply.
Use original spare parts only.
WARNING
Danger to life from uncontrolled movements!
Unauthorised switching on of the voltage during assembly and maintenance may lead to injuries as a result of
uncontrolled movements.
Secure the mains disconnector against being switched on or plugged in again.
Maintenance checklist
Check the following components of the ELEKTROMATEN at least once a year. Follow all applicable directives
and standards as well as national regulations.
Component Procedure
Mains supply,
mains switch
Check the condition and function.
Cables Check the cables on the ELEKTROMATEN for damage and replace damaged
cables.
Mountings Check screws for corrosion and tight fit. Tighten if necessary.
Limit switches Move to final limit positions OPEN and CLOSE The door must open or close fully.
The emergency limit switch must not switch.
Brakes Carry out a brake test. Note the overrun. The brake must be replaced after 50,000
switching operations.
Gearbox The gearbox has lifetime lubrication. Check for oil leakage. A few drops are not
critical. In the case of major oil loss, contact the service department. Do not open
the gearbox. Do not add any oil.
Chain drive Check sprocket and chain for wear.
Check the chain alignment. Adjust if necessary.
Check the chain tension: The slack in the slack strand should not exceed the height
of a chain link. A tension that is too high will damage the gearbox. A tension that is
too slack may result in the chain skipping or jumping off.

A
djust the chain if necessary.
Cleaning
Use a cloth to remove dirt from the surface of the housing. Do not use water or detergents. Do not open the
