Motor control unit DCM31
5 / 35
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.
