1. DESCRIPTION
With this DALI link module, you can connect several DALI buses together, making it possible to control zones which are separated by folding doors, adjoining
zones, or installations with more than the maximum number of 64 DALI units per bus. The module's design makes it easy to integrate into the installation, and
it does not require a 230 V supply.
The module can be used with the DALI addressable masters with additional functionalities (e.g. 350-41650, 350-41750, 350-41751, 350-41761 ...).
2. INSTALLATION
Connect the DALI module according to the wiring diagram in Fig. 1.
2.1. Connecting lighting in zones with folding doors
In zones with folding doors, you may sometimes want to control the lighting simultaneously with the push-button switches (if the folding door is open) and
sometimes separately (if the folding door is closed).
For this application, both sides of the zones are considered as separate zones.
1. In each zone, place a detector which is connected to the luminaires.
2. Connect the two DALI buses with each other via the DALI link module (see Fig. 1).
3. Connect a switch to the link module with which you can determine whether the zones are connected to each other or not.
If the switch is ON, the zones are connected to each other and the lighting will be controlled in both zones simultaneously. If the switch is OFF, the lighting in
each zone will be controlled individually (see Fig. 2).
2.2. Keeping the lights on in adjoining zones:
In order to save energy, daylight-controlled lighting is usually chosen these days, whereby the lighting in the zones and hallways is switched off as soon as these
are empty. Sometimes a zone in which a meeting is taking place is the only zone in a building which is still illuminated. People can then have the impression
that they have been left alone in the building.
To avoid this, you can use the DALI link module to connect the DALI buses with each other and keep the lighting in adjoining zones switched on (see Fig. 3).
2.3. Controlling several adjoining zones
With this DALI link module, you can link several zones together.
Starting from the 'master zone', (the zone where activity is detected), you can determine via the link module the behaviour in the adjoining zone.
You can connect one adjoining zone to another via the next link module. By this we mean an adjoining - adjoining zone, or second adjoining zone.
You can connect this second adjoining zone to yet another adjoining zone via the next link module. This is then the 3rd adjoining zone.
The previous adjoining zone always functions as the master zone for the next one.
3. COMMISSIONING
The DALI link module can perform ten different functions. You can select the desired function from 0 to 9 with the rotary switch on the device (see Fig. 4A). For
certain functions, you can apply additional settings with the jumper (see Fig. 4B).
3.1. Functions 0, 1 and 2 to control several adjoining zones
With these functions you can determine the behaviour in the adjoining zones, when movement is detected in the master zone but not in the adjoining zone. You
can choose from the following three functions:
• Function 0: the first adjoining zone functions with normal daylight control
• Function 1: the second adjoining zone functions on 50% of the daylight control (50% of the normal level)
• Function 2: the third adjoining zone adjusts to the minimum level.
For example:
When the rotary switch is set to Function 1, in the adjoining-adjoining zone the light will be adjusted to 50% of the normal level if there is activity in the master
zone, but nothing is detected in the second adjoining zone.
You can determine the number of adjoining zones that are activated with functions 0, 1 and 2 using a jumper (see Fig. 4B). You can set this jumper to the
following three positions:
• Jumper position 1 (one adjoining zone): place the jumper over the two pins on the left side.
• Jumper position 2 (two adjoining zones): place the jumper over the two pins on the right side.
• Jumper position 3 (three adjoining zones): do not place the jumper.
