Extension module

for the control of blinds

RXC41.1

RXC41.5

Extension to the

RXC30 / RXC31 / RXC38 room controller

The RXC41 extension module is used in conjunction with an RXC30 / RXC31 /

RXC38 room controller for the control of blinds in individual rooms.

• Control of two electric motors for blinds

• Application software downloadable into RXC30 / RXC31/ RXC38 basic module

• Plug-in connection to RXC30 / RXC31 / RXC38 basic module for power supply

and data

• Volt-free relay contacts for motor control

• Built-in fine-wire fuse for protection of the relay contacts and motors

(RXC41.1 only)

Application

The RXC41 module acts as an I/O extension to the basic RXC30 / RXC31 / RXC38

room controller. The input/output configuration is optimized for the control of two

electric motors to operate blinds.

The RXC30 / RXC31 / RXC38 basic room controller and the RXC41 extension module

are connected electrically and (when the terminal covers are fitted) mechanically to

form a single unit. If required, this can be supplemented with a second RXC41 module

or an additional RXC40 extension module for the control of lighting.

For operation, either conventional momentary-contact switches, or integrated operating units with a bus connection may be used. The application software for the complete unit, comprising the basic module and the extension module(es) is downloaded into the RXC30 / RXC31 / RXC38 room controller. Where the RXC30 / RXC31 / RXC38 controller is loaded with basic application 00030 / 00031, test functions for the RXC41 extension module are also available.

Mechanical design The RXC41 extension module consists of a housing base, a housing cover and the printed circuit board with connection terminals. The module also has a ribbon cable and connector for connection to the RXC30 / RXC31 / RXC38 basic controller (or the preceding extension module) and a connector base into which a further extension module may be plugged. The motors and relay contacts for control of blinds are protected by a replaceable fine-wire fuse (RXC41.1 only).

3834J01 STOP Note! Cable restraints on the housing base must be used for the connections to terminals 7 … 17 (AC 230 V). The conductors must be secured with cable ties (see diagram). Warning! Ensure that the power is off before inserting or removing plug-in terminals connected to a mains voltage. Built-in fine-wire fuse To protect the volt-free relay contacts and motors for control of the blinds, the module incorporates a built-in replaceable fine-wire fuse (RXC41.1 only).
PAGE 5
AC 250 V volt-free relay outputs Cable sizing for motorized blinds depends on the connected load and the local installation regulations. Neutral and protective conductors are looped on the controller so that there is no need for external terminals. The cables must be secured with cable restraints. An interlock makes outputs Q14 / Q 24 and Q34 / Q44 mutually exclusive. To protect the cables, the circuits must be fused in accordance with local regulations. STOP Note! RXC41.
