2.1) Electrical connections
Carefully follow all the connection instructions, if you
have any doubts do NOT make experiments but consult the
relevant technical specifi cations sheets which are also
available on the web site www.stobag.com. An incorrect
connection may cause serious damage to the control
unit.
N.B. The output for motor M2 is only available on control unit SRCR
200 A.
2.1.1) Motor connection
The single-phase asynchronous M1 motor powered by the electri-
cal mains must be connected between terminals 1-2-3-4. DESCENT
corresponds to the ▼ key on the radio controls, ASCENT to the
▲ key (anemometer triggering direction). If the rotation direction is
not correct, invert terminals 1 and 3. M2 single-phase asynchronous
motors powered by the electrical mains, must be connected be-
tween terminals 5-6-7-8. If the rotation direction is not correct, invert
the connections to terminals 5 and 7. In the synchronised operating
mode, motor M1 is the one the limit switches are adjusted in; on M2,
the limit switches are not used and are adjusted in order to ensure
they will not trigger.
2.1.2) Power supply
The main supply to the unit must be connected using the terminals
9-10-11 (earth, phase, neutral).
2.1.3) ASCENT and DESCENT inputs
The user must connect two keys as shown in Fig. 6 in order to con-
trol the automation. It is possible to control an ascent manoeuvre
(which corresponds to the ▲ key on the radio controls) or a descent
manoeuvre (which corresponds to the ▼ of the radio controls). Alter-
natively, it is possible to use one key only by connecting it up as
shown in Fig. 7. The operating mode will be "step-by-step" with this
type of connection, which carries out the sequence: ascent-stop-
descent-stop. If the "step-by-step" key is held down for more than 3
seconds (but less than 10) an ascent manoeuvre will be activated. If
the key is held down for more than 10 seconds, a descent manoeu-
vre will be activated. This may be useful for controlling more than one
motor for the same manoeuvre, regardless of the state they are in.
2.1.4) TTBUS input
TTBUS has been developed in order to control the control units for
awnings and rolling-shutters and those motors with a control unit
which can be used for this purpose. The Bus makes it possible to
2.1.5) WEATHER SENSORS input
Either a wind-sun sensor ("SKIROSOL SRCK 601") or a wind-sun-rain
sensor ("SKIROSOL SRCK 630") can be connected to the "Climatic
sensors" input (terminals 14-15). A total of 5 control units in parallel
can be connected up to the same sensor, taking care to respect the
polarity of the signals (on all the control units terminal 14 must be
connected with the 14, and terminal 15 with the 15).

In control unit SRCR 200 A with the "synchronised" op-
erating mode, that is with the two motors assembled on
the opposite sides to the shutter, it is necessary to make
the electrical connections in such a way that the rotation
directions both move in the same direction. This normally
occurs by inverting the M2 connections with the M1 ones.
With the "synchronised" functioning mode, it is not possi-
ble to connect more than one motor. Moreover, it is not
possible to use EZ 210 expansion cards.
Do not connect more than one motor to each output if
control unit SRCR 200 A is to operate in "independent"
mode nor in control unit SRCR 180 A; if necessary, use the
appropriate EZ 210 expansion cards.

control up to a 100 units individually, by simply connecting them up in
parallel with just 2 conductors (terminals 13-15). Further information
is provided in the instructions for remote controls via TTBUS.
If the "wind" sensor triggers, this will cause an "ascent"
command (the equivalent of ▲ transmitter key); if the "sun"
sensor triggers, this will cause a "descent" command (the
equivalent of ▼ transmitter key).
