SL1807
Control unit
This unit is used to control the polarity inversion necessary for
the correct function of the motor, which would not be realised
when using normal switches.
Each control unit can control one blind, or can simultaneously
control a group of up to four blinds, depending on the requi-
rements of the system.
The limited dimensions of the unit allow its insertion inside the
standard electrical back box.
It comprises an electronic card equipped with a protection fuse
that can be easily replaced.

Note
The
REMOTE
terminal is available to allow the installer the opportunity to meet the client’s
requirements for a variety of group control combinations. This is achieved by connecting the
REMOTE terminal to the MOTOR output terminal of another SL1807 CONTROL UNIT. A typical
application would be where a single control is required for a number in blinds already control-
led individually by a control unit. By connecting a new control unit via the MOTOR output in
parallel with all the REMOTE terminals of the existing control units involved in the total opera-
tion, the additional control unit, once has been activated, will control all the control units simul-
taneously, whilst still allowing control of each motor separately.
Multiple control systems can be built up using this procedure.
