3DIM INTERFACE (ECG TERMINALS)/MODE SELECTION

The wiring depends on the desired functionality (DALI

®

,

StepDIM or AstroDIM) and purpose of use (operation
or confi guration). The different wiring options are de-
scribed in chapter 5. All 3DIM ECGs have a terminal block
for connection. The individual terminals are marked as
shown in table 1.

All 3DIM ECGs are able to perform only one mode
(DALI

®

, StepDIM, StepDIM inverse or AstroDIM) at a time.

For comissioning of the ECG it is possible to select the
mode via external wiring or with the 3DIM Tool.
By default, the ECG is operated according to the so-called
“StepDIM/AstroDIM/DALI (wiring selection)”.

3.1. Via wiring selection (factory settings)

• DALI

®

is always supported and has priority over the oth-

er functions (even if AstroDIM or StepDIM are executed).
As soon as a valid DALI

®

command is sent to the ECG,

it switches immediately to DALI

®

operation. During this

switch, the output level of the ECG is not changed un-
less initiated by another DALI

®

command.

Note: After a DALI

®

command has been received, the

ECG stays in DALI

®

operation until it is switched off.

• The AstroDIM function is selected by establishing a

permanent connection between phase (L) and the SD
terminal of the ECG inside the luminaire compartment
(see chapter 4.3.). It is activated as long as no DALI

®

command is received.

• StepDIM is operated via a dedicated control line or a

switched phase (see fi gure 18a/b), which is not powered
during the start-up phase of the ECG (at least 1 s).

3.2. Via 3DIM Tool software

The following operating modes can be selected via the
3DIM Tool:
• “StepDIM/AstroDIM/DALI (wiring selection)”
• “AstroDIM/DALI”
• “StepDIM/DALI”
• “StepDIM inverse/DALI”
• “DALI”

For more details go to chapter 4.

Notes:
• The factory settings can vary depending on the

specifi c ECG.

• Not all ECGs are able to run all operating modes.
• A typical half-night switch application (Bi-Power)

requires the “StepDIM inverse/DALI” mode, which
can only be set with the 3DIM Tool.

For more details, please refer to the datasheet or
instruction sheet of the respective ECG.
