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.
