Description of functions
Shade function, general
With the shade function, the blind drive is connected in such a way that
Relay 0 (OØ ) controls upward movement and
Relay 1 (O1) downward movement.
The two outputs are interlocked, so both outputs cannot be activated together. For
the correct operation of shade control, the only input information should be from
sensors.
The module is set up to use blind systems with integrated limit switches.
Suppressors should be fitted externally. The module can be operated by the Saia
PCD
®
via an FBox or via the inputs (blind/light switches) on the module. The
choice of function and initialisation with the various times is handled exclusively by
