System information
This unit is a product of the Instabus-EIB-System and
corresponds to the EIBA Guidelines. Detailed techni-
cal knowledge acquired in Instabus training courses
is a prerequisite for the understanding of the system.
The functions of the device are software-dependent.
Detailed information on the software and the func-
tions implemented and the software itself are avail-
able from the manufacturer’s product data bank.
Planning, installation and commissionning of the de-
vice are effected with the help of EIBA-certified soft-
ware.
For the productdatabase and technical descriptions
please refer to the Gira Datenpool CD, order no.
1992 10, or to the internet at www.gira.de offering up-
to-date information.
Function
The control unit reveives telegrams transmitted via
the Instabus EIB and switches or dims fluorescent
lamps in combination with electronic ballasts. During
dimming, the electronic ballast is controlled from a
1-10 V interface. Switching is effected by a relay con-
tact that switches the ballast’s voltage supply on and
off. This contact can also be actuated manually with-
out any effect on the bus.
Characteristics
• Connection of different phases to terminals A1 –
A3.
• Switching and dimming behaviour presettable with
parameters.
• Checkback for switching status.
• Transmission of brightness value.
• Soft-On, Soft-Off and delayed dimming presettable
with parameters.
• Light-fading mode and immediate brightness
change.
• Lightscape operation possible.
• Behaviour on bus voltage return presettable.
Important information
• The number of electronic ballasts that can be
dimmed via the 1-10 V interface, depends on the
ballast-specific load current of the types used.
• Please observe: electronic ballasts produce high
peak currents during switch-on, which might cause
the relay contacts to stick together. For loads up to
max. 200 VA per channel we recommend using an
inrush current limiter (Art.no. 0810 00).
• For greater loads we recommend using separate
load-switching relays.

Safety warnings
Attention: Electrical equipment must be installed
and fitted only by qualified electricians and in ob-
servance of the applicable accident prevention
regulations.
To prevent electric shocks, disconnect the pow-
er supply before working on the device (by cut-
ting out the circuit breaker).
Any non-observance of the fitting instructions
may cause fire or other hazards.
