Dickert Electronic DCM31 - B) Radio

Motor control unit DCM31
10 / 35
- Simultaneous actuation of input A and input B has an emergency stop function.
[Kl.28]+[Kl.29] antenna
- An antenna litz wire must be connected to [Kl.29] and must be stretched parallel to
the main reception direction along its whole length.
- The antenna litz wire can be fed out through the small hole next to the self-sealing
plugs.
- The largest range is achieved by laying the cable at a large distance from the metal
parts (concrete ceilings, cables, ...).
- If a rod antenna is used, the shielding of the coax cable is connected to the
adjacent earth terminal [Kl.28].
[Kl.30]+[Kl.31] transformer connection (primary 230V/AC)
[Kl.32]+[Kl.33] transformer connection (secondary 24V/AC)
- An external power transformer (usually installed in the factory) must be connected
to [Kl.30] and [Kl.31] (primary) and [Kl.32] and [Kl.33] (secondary).
- For safety and EMC reasons, a short-circuit proof toroidal transformer to EN60742
(VDE0551) must be used.
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]
- A suitable radio receiver must be plugged in, with the correct orientation, in the
2x10-pin socket connector [Bl.2] [X9] [X10].
- Channel 1 is internally connected parallel to input A.
- 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.
