1) Intended Purpose
This motor control unit is intended for the following 24V/DC drive units:
- On one or two-leaf garage or courtyard gate systems (e.g. hinged, sliding, tilting
and up-and-over gates)
- In industrial, residential, business and commercial areas and in small businesses
- According to the stipulations in these instructions.
These instructions are intended for the fitter of the control unit and the processing
industry, however not for issue to the owner/operator of the gate system. The end
product manufacturer is responsible for preparing suitable instructions for the complete
gate system.
a) Requirements
The motor control unit is not operational until it is installed in the ready for use gate
system.
This requires external components such as e.g. ...
- command input devices,
- signalling devices,
- sensors and
- the drive unit,
but which are not supplied with this motor control unit.
This control unit is therefore a "non ready for use component" from a legal point of
view. It therefore does not fall within the scope of various EC Directives until it is
integrated in the end product (gate system).
b) Legal requirements
The end product manufacturer is thus responsible for compliance and declaration of
CE conformity. The control unit complies with the requirements in
- DIN EN 60204. This makes it easier for you to carry out the conformity assessment
according to the Machinery Directive.
- DIN EN 50081 T1/2 and EN 55011 and EN 55014. This makes it easier for you to
carry out the conformity assessment according to the EMC Directive.
- VDE 0700 Part 95 (Draft 02/98; IEC 60335-2-95) and EN 12445 and EN 12453
concerning requirements for motor control units for "power-driven doors and gates"
(formerly ZH 1/494).
- DIN EN 60335-1. This makes it easier for you to prepare the declaration of
conformity according to the so-called "Low Voltage Directive".
- EN 61 508, SIL2, Functional Safety.

c) Technical qualification requirements
These instructions require technical knowledge, which corresponds to completed
vocational training in at least one of the following job profiles:
- Electrical fitter,
- Electrical installation fitter,
- Electrical machine fitter,
- Electro-mechanic,
- Industrial electronics technician ...
or knowledge as an (electrically) skilled person according to the German accident
prevention regulation BGV A2 (VBG 4).
The product is supplied as a component in "especially EMC-expert firms" in
accordance with EMC law.
d) Important safety instructions
- Reliable operation is only possible if the unit is carefully installed according to these
instructions. We do not provide any guarantee or accept liability for any damage
caused by failure to comply with these instructions.
- During the learning runs / putting into service of 2-leaf gate systems with closing
edge, check setting of the correct door closing delay of the motors and if necessary
correct, so that the closing edge does not travel at a flat horizontal angle to the
other leaf, which could cause damage to the gate system and to risks for objects
and people!
- After installation, the customer of fitter of the gate drive unit must check for
compliance of the maximum closing forces according to the standards EN 12445
(Safety in use of power operated doors, test methods) and EN 12453 (Safety in use
of power operated doors, requirements) or the applicable standards and regulations
at the respective installation location!
- The safety equipment requirements e.g. depend on whether the gate is used in a
private or commercial area, whether it is in a public street or the controls are
generally accessible
- Information is available from electric power suppliers, VDE and the employers’
professional insurance association.
- ESD-compatible earthing must be ensured for all work on the control unit.
Otherwise there is a risk of damage or even destruction of the control unit.

2) Installation
This requires 4 screws with a shank diameter of 4mm.
a) Suitable installation site
The motor control unit is supplied as a module in a simple plastic housing. You should
therefore choose an installation site with the following conditions:
- The ambient temperature may not be lower than -20°C and not higher than
+50°C.
- The air humidity must lie within 30...90% RH.
- Electromagnetic fields at the installation site must be reliably shielded.
- Preferably protected against direct sunlight and driving rain
b) Installation
The internal temperature rating is designed for vertical installation.
[X1], [X5] show the installation, whereby the cables must be brought out at the bottom
and sealed with the enclosed threaded joints to prevent penetrating moisture.
When choosing the type of fixing, you must take into account the weight of the control
unit (see technical specifications).
Properly fit the control unit housing in the suitable installation site.
3) Brief Explanation of Terms Used
You will come across the following terms in these instructions, not in everyday use:
Release / release time
In various safety functions you can choose how the gate is to behave in a given
situation. In the event of “release” the gate only moves for the set release time in
“opposite direction”, in order to release the obstruction.
Active leaf
In 2-leaf gate systems, one leaf can be chosen as the “active leaf”. This can then be
opened separately (e.g. as a doorway for people).
OSE
Self-monitoring Optical Safety Equipment as photoelectric barrier or as contact
strip.
Panic function
In the panic function an open/close command during a gate travel always results in the
stopping of the gate travel. The gate only starts to move in the required direction if
actuated again.
Reversing
If various safety functions you can choose how the gate is to behave in a given
situation. In “reversing” the gate moves in the opposite direction to the end position.
Smooth travel-out

Motor control unit DCM31
6 / 35
The motor output / motor speed can be reduced over the last part of the travel path so
that the gate does not hit the end stop at full speed.
Electricity stop
The control unit monitors the motor current for obstacle detection. You can choose
how the control unit reacts if the set value is exceeded.
Partial opening
The gate can be specifically moved to a previously selected position between the limit
switches (e.g. to allow people through).

b) Radio
[X8], [X10]
- The control unit can be remotely controlled, either via the radio module (evaluation
and storage of the radio code in the controller of the control unit) or via a radio
receiver with integrated logic for evaluation and storage of the radio code. The
radio receiver and radio module work independent of each other.
Radio module mode [Bl.1]
- A suitable radio module must be plugged with correct orientation into the 15-pin
socket connector [Bl.1] [X9] [X8].
- Replace radio module: (frequency change): If noise exists in the frequency band
used, the control unit can be converted to another frequency by replacing the radio
modules.
- Procedure:
• Switch off power supply!
• Carefully pull the radio module out of the plug-in holder.
• Plug-in the new radio module with the required frequency with the “correct
orientation”.
• Switch supply voltage back on.
• Delete radio (see p 20).
• Teach new sender (see p 20).
• The transmitters must have the same frequency as the new radio module!
Radio receiver [Bl.2]

- Channel 2 is internally connected parallel to input B.
- The function of channels 1 and 2 is set via [M.b9].
- Refer to the respective operating instructions for information on how to use the
radio receiver.
