Frequently Asked Questions - GW12796 Gewiss

How to install the GW12796 actuator?

Installation must be carried out by qualified personnel. Insert the device into a Chorus support, positioning the local control button on the left. Connect the KNX bus via the plug terminal and the load via the screw terminals. Apply the finishing plate. Configuration is done with ETS software.

How to configure the physical address with ETS?

Use the miniature programming button (red LED) to assign the physical address via ETS software. Press the button to put the device into programming mode, then download the configuration from ETS.

What types of lamps can I control?

The actuator supports resistive loads (16 A), incandescent lamps (10 A), non-phase-shifted fluorescent lamps (4 A), lamps with electronic ballasts (4 A), and motors (10 A). It is not suitable for phase-shifted fluorescent lamps and discharge lamps.

What to do if the LED does not light up?

Check the presence of KNX bus voltage. The actuator is powered by the bus; without bus voltage it does not work. Check the connections and bus wiring.

How to use the staircase timer function?

The staircase timer function is configurable via ETS. You can set the delay time and activate a pre-warning before extinction. The actuator will automatically turn off the load after the set delay.

Can I control the actuator remotely via the bus?

Yes, the actuator receives switching commands from control devices or sensors of the KNX system via the bus. It also sends status information on the bus.

What is the difference between NO and NC contacts?

The NO (Normally Open) contact closes when the relay is activated, the NC (Normally Closed) contact opens. At rest, NO is open and NC is closed. The output contact is a common changeover.

How to reset the device?

To reset the physical address, use the programming button. To restore factory settings, refer to the technical manual. In case of bus voltage drop, the behavior is configurable via ETS.

What does the amber LED mean?

The amber LED indicates night location. It allows locating the device in the dark. It is lit when bus voltage is present.

Is the actuator compatible with other KNX brands?

Yes, the actuator is certified KNX/EIB and can be integrated into any KNX system, regardless of the brand of other devices, subject to configuration compatibility via ETS.

TECHNICAL DATA 17

GENERAL DESCRIPTION

The KNX 1 channel 16 A Actuator - flush-mounted, allows you to activate/deactivate an electrical load using 1 16 A relay fitted with 1 output exchange contact (1 NO/NC). The relay switching command can be given by Building Automation control or sensor devices using the KNX/EIB bus, or they can be generated locally using the front button. The actuator is powered by the bus line and is fitted with a green LED which indicates the output status and an amber LED for night localisation. This device sends to the bus information on the relay status (ON = NO contact closed, 0FF = NO contact open) at the ignition, at the reception of a command and when it is commanded via the local button.

WARNING: the local command buttons are enabled only when the BUS power is available.

Functions

The actuator is configured by the ETS software to achieve one of the functions listed below.

Switching:

• Timing of stairway lights with option to set the length of the time via bus
• timing of stairway lights with off prewarning function
• activation/deactivation delay
• flashing

Scenes:

• Memorising and activation of 8 scenes (value 0-63)
• Enabling/disabling memorising of scenes via bus

Priority controls:

• Setting of output relay value parameters at the end of an override

Block command:

• Setting of the blocked object value and the output relay value at the end of the block

Logic functions:

• AND/NAND/OR/NOR logic operations with command object and logic operation result
• AND/NAND/OR/NOR/XOR/XNOR logic operations up to 4 logic inputs

Output status:

• Sending to bus with settable parameters

GENERAL DESCRIPTION

Safety functions:

• Periodic monitoring of input object

Other functions:

• Output behaviour setting during bus blackout/reinstatement
• Local command button behaviour settings
• Priority settings for input objects
