Installation instructions

1.2.7 External up/down inputs

Each group has its own external up/down input. This inputs require a poten-
tial-free switch. It is possible to switch more inputs with the same switch at
the same time.
Connect the switch to the desired input and the common terminals (140, 149,
150 or 159).

1.2.8 Window cleaning and maintenance inputs

The window cleaning/maintenance inputs can be used to block the sunshade in a spe-
cific position. This is very important when the windows are cleaned or maintenance is
carried out. Each group has its own input.
Connect a keyswitch to the input and the common terminals 160 and 169. It is possible
to connect more inputs to one keyswitch.

1.2.9 Rain sensor

The rain sensor is connected with 6 wires. The connections on the rain sensor 1–6 cor-
respond with connections 170–175 on the VBC. With the 2 DIP-switches on the right of
the terminal block the sensitivity of the rain sensor can be set.

1.2.10 Fire input

The fire input can be used to connect the VBC to a fire alarm system. Connect a normally open potential-free
contact from the fire alarm system to terminals 176 and 177 of the VBC (see picture chapter 1.2.9). Note that
if the input is not used, the terminals 176 and 177 must be bridged by a wire.

1.2.11 Signaling relay output

The signaling relay (terminals 178 and 179) can be used to signal errors or status to other systems. It is an
potential-free relay output. This relay contact can only be used for low voltages, up to 40 Volt and maximum 1 A.
