1.1 Installation
1.1.1 Disconnect the power
1.1.2 Select which type of switch will be connected (fig.1)
1.1.3 Wire either switches (fig.2) or dry-contact relay outputs (fig.3) to the indicated
DCT terminals at the bottom of the DCT2RTS Interface.
1.1.4 Connect the power. The status LED will turn green to indicate the device is
operating.
1.2 RTS commissioning
Before using the DCT2RTS interface, we recommend programming each motor in
advance using an individual Somfy remote control (e.g. Situo) and set the limit
positions of each motor.
1.2.1 Procedure
1. Select the channel of the motor on the existing remote control, hold the
program button on the remote for 3 seconds, for the motor to jog
2. Select the desired channel (channel 1 – channel 5) via the RTS channel selector.
3. Press and hold the RTS PROG button for 1 second.
4. RTS motor jogs; the motor is now programmed to DCT2RTS gateway.
5. Repeat the same procedure to remove a motor from the DCT2RTS gateway.
1.2.2 RTS motors functional test
1. Select the channel via the RTS channel selector.
2. Press the UP/DOWN button on DCT2RTS interface to control RTS motors.
3. The motor jogs to indicate the connection is successfully established. If the
motor does not respond to the command, it means the establishment failed.
Repeat 1.2.1 Procedure, Steps 1-4 again. Alternately it may simply mean
that the RTS motor has been removed.
1.3 Operation
1. To activate an UP command, a minimum of 0.5 second closure is required
between the UP and COM terminals (5VDC). The status LED turns blue to
indicate that RTS signal is sent.
2. To activate a DOWN command, a minimum of 0.5 second closure is required
between the DOWN and COM terminals (5VDC). The status LED turns blue to
indicate that RTS signal is sent.
3. To activate a STOP command, a closure is required between UP, DOWN and
CMD terminals.
Attention:
Press and hold the RTS_PROG button for 5 seconds, the concerned RTS motor will enter to RTS
programming mode.
