DALI group controllers: DALI GC & GC-A
Description
DALI-GC is a module that enables dimming commands to be sent to two groups (groups A and B) on the DALI circuit.
Any standard momentary switch can be connected to the module. Its compact design means that DALI-GC can be
installed together with the standard momentary switches in a flush-mounted box, so set-up of the DALI circuit can be
decentralised. Either individual switches or UP/DOWN switches can be used for controlling the groups. The controlled
groups are set on a rotary switch on the module.
The DALI GC module is multi-master-compatible so several control modules can be used in a DALI circuit. It is also
possible to address and group simple DALI circuits with the aid of DALI-GC.
DALI-GC-A is similar to DALI-GC. The only difference is that the programming mode is not activated in DALI-GC-A.
This prevents the DALI units from being reprogrammed unintentionally via the switches.
Connection
The DALI-GC switch module is connected directly to the DALI control line and does not need a separate power supply.
It is powered via the DALI circuit (current draw = 6 mA). It can be connected to the DALI circuit with either polarity.
Either single momentary switches or UP/DOWN momentary switches can be used for controlling a group. If a single
switch is used the UP/DOWN connections are simply connected in parallel. It is also possible to operate the two
groups (A and B) with different types of momentary switch; for example group A with UP/DOWN switches and group B
with a single switch.
