Product Description
The G3448 5238 2-output
lighting scene dimmer is a
component of the Dupline
Installation System. It allows
different types of electronic
ballasts to be operated and
dimmed and enables up to 4
lighting arrangements (per
output) to be stored, which
can then be retrieved at any
time. In addition, it transmits
the status of the dimming out-
put for every individual output.
The dimmer setting which
was selected last is stored as
a "memory setting" in the
internal memory and is rese-
lected next time the lighting is
switched on via channel 1/5.
A power failure will erase the
memory setting. The bright-
ness of the lighting scenes is
preset at the factory in steps;
these settings cannot be
altered. By the aid of push-
button combinations or by
means of the test unit, the
lighting scenes can be
unlocked, modified and also
retrieved. The lighting is
switched on via a bulb-pre-
serving softstart facility.

Mode of Operation
Coding
With the GAP1605 programming unit, each switching channel
can be assigned any address between A1 and P8 via the mo-
dular socket on the front of the dimmer. The allocation of the
channels is as follows:
Functions which are not required should remain uncoded. The
coding of the dimmer can be carried out without either supply
voltage or Dupline signal. It is retained permanently, but may be
overwritten at any time. The Dimmer outputs are configured in
such a way at the factory that they will be switched off in the
event of a fault. This configuration, too, can be changed with
the GAP1605. Setting "1" results in switching on the lighting to
100% in case of a fault, while setting "0" switches off the Dim-
mer outputs (factory setting).
Putting into service
Commissioning may only be carried out by an authorized,
trained technician. Observe the connection diagram when
installing. All lines to be connected must be dead.
The following table shows the allocation of terminals:
Functions and programming
The dimmer is programmed with the GAP1605 programming
unit. Up to eight addresses can be programmed, 2 x 3 of which
(IN/OUT 1-3, 5-7 of the GAP1605) are dedicated to controlling
the dimmer itself (light level) - see the following table "Factory
Settings". The remaining two addresses (IN/OUT 4, 8 of the
GAP1605) are output signals on the bus and indicating if the
dimmers are activated. The addresses are selected in the con-
figuration software as push button channels.
The eight addresses (including two status signal addresses)
The light levels 3 and 4 can be programmed by combining 2
addresses.
( ) Factory settings
The shown values are factory settings and are consequently
protected against accidental resetting. Nevertheless, it is possi-
ble to disable the protection to change the default values. The
following steps 1-4 explain how the protection can be disabled,
the values changed, the protection reestablished and default
settings restored. The steps are explained with addresses for
Dimmer 1, but the same is valid for Dimmer 2.

Connections between the Dupline signal and to earth potential
will cause malfunctions and are not permissible. Attention
should be paid to the correct polarity of the supply voltage and
the Dupline signal. In order to meet the requirements for protec-
tive low voltage, VDE 0100, part 410, should be observed and
applied during installation.

1. Programming access (Unlock)
a) Activate address 2 and 3 for approx. 6 seconds.
b) When the light starts dimming fast up to 100%, down to
10% and back to actual value, the programming access
is open.
2. New light level
a) Open for the programming access according to 1. Pro
gramming access.
b) Use address 1 to set the required light level.
c) Activate, for approx. 3 seconds, the address to which the
chosen light level is to be allocated.
d) When the light starts dimming fast up to 100%, down to
10% and back to actual value, the new light level is
stored.
Undesirable changes of the programmed parameters can be
avoided by reestablishment of the programming protection
see 3. Protection.
3. Protection (Lock)
a) Activate address 2 and 3 for approx. 6 seconds.
b) When the light starts dimming fast up to 100%, down to
10% and back to actual value, the programming access
is closed.
4. Restoring of factory settings
a) Activate address 1, 2 and 3 for approx. 9 seconds.
b) When the light starts dimming fast up to 100%, down to
10% and back to actual value, the factory settings are
restored.
When the factory settings are restored the programming pro
tection is not active.
