General safety information

1 General safety information
Specified normal use
The door control is intended for a force-actuated door with drive unit and mechanical limit switch
(NES) by GfA.
The safe operation is only guaranteed with specified normal use. The door control and the drive unit
are to be protected against rain, moisture and ambient environmental conditions.
There is no liability for damage caused by other applications or failure to follow the installation
instructions. Modifications are only permitted with the agreement of the manufacturer. Otherwise the
Manufacturer’s Declaration shall be rendered null and void.
Safety information
Only skilled personnel may carry out the installation and commissioning. 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. Installation
work may be carried out only in a voltage-free state. Observe valid regulations and standards.
Coverings and protective devices
Only operate with corresponding covers and protective devices. Ensure proper seating of gaskets and
correctly tightened screw connections.
Spare parts
Use original spare parts only.

3 Components
3.1 Motor protection switch
Motors for use in potentially explosive atmospheres (Ex) require protection against overload and short
circuit. Overload protection is provided by a built-in motor protection switch (Q2). The motor protection
switch is suitable for Ex-d/Ex-de and Ex-e motors. The protection is current-dependent and becomes
effective when the motor is blocked. Only manual reset is permissible. The setting value of the
overload device must correspond to the rated motor current. For Ex-e motors, it must be ensured that
the motor is disconnected from the mains within the warming period tE. The actual tripping time tAat
relative operating current IA/ INmust be determined using the tripping characteristic of the motor
protection switch. It must be ensured that tA< tEis given.
3.2 Zener barriers
Zener barriers of series 9001 are used as isolation stages without galvanic separation between
intrinsically safe and non- intrinsically safe current circuits. Zener barriers protect current circuits (such
as conductors and equipment) installed in explosive atmospheres. As they also contain non-
intrinsically safe current circuits, Zener barriers must be installed outside the explosive zone. Zener
barriers represent associated equipment.
3.3 Safety edge system
The Zener barrier N1 is an associated device without galvanic isolation. This barrier is suitable for
zones 1, 2 (gas) as well as 21, 22 (dust) and may be used in combination with an electric safety edge
as a safety edge system. The safety edge is connected directly to the Zener barrier. For example, the
rubber profile "Contact-Duo" by GELBAU can be used as safety edge. The design of the rubber
profile must be suitable for Ex atmospheres. The safety edge must be equipped with an end of line
resistor of 8k2 ohms. The power dissipation of the resistor must be observed (a resistance of 1W
corresponds temperature class T4).
Ex-factory, a resistor R1 of 8k2 Ohm is connected to terminals 3-4. This resistor is for test purposes
only and must be removed after commissioning.

3.4 Pass-door / slack-rope switch
The Zener barrier N2 is an associated device without galvanic isolation. This barrier is suitable for
zones 1, 2 (gas) as well as 21, 22 (dust) and serves to evaluate a switch contact (pass-door / slack-
rope switch). Multiple contacts must be connected in series.

C

3.5 Switch device
The 2-channel switch device A2 serves as an interface between signals from the explosive
atmosphere and the non-explosive atmosphere. Due to the galvanic isolation, no connection to the
potential equalisation is required. The switch device is considered an associated device.
LEDs (power: green, status: yellow, error: red) signal operational readiness and output status.
Any photocell built and tested according to NAMUR standard with Ex approval may be connected to
the switch device.
In principle, the photocells are approved zones 1 and 21. The photocell must be connected
unblanking.

4 Installation
Before installation, the door control must be checked for transport or other damage. The base for
attaching the door control must be level and free of vibrations. The door control must be easily
accessible and be installed between 0.6 m and 1.7 m above the floor. Installation is only permissible
in vertical mounting position. Ensure that no foreign bodies (such as drilling chips) enter the housing.
4.1 Mains supply
The door control is intended for three-phase drives with a mains voltage of 3 ~ 230 V and 3 ~ 400 V.
The mains connection point must be protected with the specified backup fuse. Use copper cables with
the appropriate cross-section to avoid excessive voltage drop during start-up and during operation.
The motor voltage must be within a limit of +/- 10%. The outer diameter of the cable must correspond
to the cable gland's diameter.
4.2 Motor connection
Choose the size of mains cables according to DIN VDE 0298. When using motors with integrated
brake, two separate lines are required. Cable entries and cable diameters are specified in the
installation instructions of the drive unit.

4.3 Other connections
- Limit switch at drive unit
- Control device in door area
- Ceiling pull switch (optional)
- A latching switch to release the automatic closing mechanism (optional)
The connection terminals are located in control circuits with 24 V DC.
DANGER
Installed devices within the Ex zone must be flameproof and have an Ex approval.
CAUTION
▶ Door operating mode "hold-to-run":
Ensure unobstructed view from the place of operation to the door.
4.4 Proof of intrinsic safety
Intrinsically safe current circuits are:
- Safety edge with resistor of 8k2 Ohm, spiral cable and connection cable
- Pass-door and slack-rope switch with connection cable
- Photo cell with connection cable
The erection regulations DIN EN 60079-14 [1] require a proof of intrinsic safety for intrinsically safe
current circuits. For technical data of equipment N1, N2 and A2, please refer to the technical data
sheets by the manufacturers.
