Ordering KeyProduct Description

The G3448 5234 2-output

lighting scene dimmer is a

component of the Dupline

Installation System. It permits

different types of lamps with

wattages up to 2 x 230 W 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 addi-

tion, it transmits the status of

the dimming output for every

individual output. The dimmer

setting which was selected

last is stored as a "memory

setting" in the internal memo-

ry and is reselected next time

the lighting is switched on via

channel 1/5. A power failure

will erase the memory setting.

The brightness of the lighting

scenes is preset at the factory

in steps; these settings can-

not 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. With the change-

over switches on the front

panel, it is possible to select

either negative phase angle

control or positive phase

angle control dimming. The

lighting is switched on via a

bulb-conserving softstart

facility. The dimmer is elec-

tronically protected at the

power output against over-

load and short circuits. The

"Fault" LED on the front indi-

cates both faults by means of

different flashing frequencies.

An alarm caused by an over-

load or short circuit must be

reset manually after rectifying

the fault by disconnecting the

phase from the mains supply

for approx. 3 seconds.

Mode of Operation

Coding

With the GAP1605 programming unit, each switching channel

can be assigned any address between A1 and P8 via the mod-

ular 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 N-con-

nection is absolutely necessary for the operation of the dimmer.

The desired operating mode should be selected before con-

necting the phase, because the switches are disabled during

operation as a safeguard against accidental r esetting.

Although an incorrect setting will result in malfunction, it will not

cause irreparable damage to the dimmer. The following table

shows the allocation of terminals:

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 r equir ements for pr otec-

tive low voltage, VDE 0100, part 410, should be observed and

applied during installation.

Functions and programming

The dimmer is programmed with the GAP1605 programming

unit. Up to eight addresses can be pr ogrammed, 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 addr esses)

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.
