Frequently Asked Questions - GW90835 Gewiss

How to install the GW90835 actuator on a DIN rail?

Insert the upper hook onto the 35 mm DIN rail, then rotate the device and lock it by acting on the fixing latch. Observe safety distances (4 mm between bus and power cables).

What is the power supply required for this module?

The actuator is powered by the KNX bus at 24 V DC. The current draw is 10 mA maximum.

How to configure the delay function on a channel?

Use the Easy Controller or Easy base unit to create a 'delay' function. Set the 'activation time' parameter (from 1 second to 24 hours) and optionally the 'pre-warning time' for an alert before shutdown.

Can the actuator be controlled locally without the bus?

Yes, each channel has a front push-button for cyclic ON/OFF switching. However, these buttons only work when the bus voltage is present.

What to do if the programming LED does not light up?

Check that the bus power is present (voltage > 18 V DC) and that the bus terminal is correctly inserted. Press the programming button briefly (< 2 s).

What types of loads can be connected?

The actuator supports resistive and inductive loads up to 10 A: incandescent/halogen lamps (1500 W), electronic transformers (600 VA), uncompensated fluorescent lamps (400 VA), and low-energy lamps (8x23 W). For compensated loads, use an auxiliary relay.

How to reset the actuator to factory settings?

To restore default settings, press and hold the programming button for more than 5 seconds until the red LED flashes. Release and wait until the LED turns off.

Does the actuator retain its state after a bus power failure?

By default, when the bus is cut off, the contacts do not change. You can configure the desired behavior (open, closed, or no change) via the configuration procedure described in the manual.

How to integrate the actuator into an existing KNX system?

Use the Easy Controller or Easy base unit for automatic or manual acquisition. Ensure the actuator is powered on and follow the steps of 'Search/Configure' or 'Add a device'.

What are the exact dimensions of the GW90835?

The enclosure occupies 4 DIN modules, i.e., a width of 72 mm (4 x 18 mm). The height and depth are standard for DIN modules (approx. 90 mm and 65 mm).

Briefly

The Easy 4-channel 10 A actuator - DIN rail mounting allows up to 4 different electrical loads to be activated/deactivated separately by means of 4 × 10 A relays, each one fitted with 1 NO output contact. The switchover command of the relay can arrive from command devices or sensors of the Home Automation system, via the KNX BUS, or be locally generated by the front push Buttons.

The actuator is powered from the BUS line and has 4 front green LEDs for signalling the output status. The device sends information to the bus about the relay status (ON = contact closed, OFF = contact open) when switching on, receiving a command and in the case of a command from a local push-button.

Each output channel of the actuator can be configured separately and allows the ON/OFF command of the controlled loads, execution of timed commands, scene management and execution of priority commands to force the output status. The operating modes can be used simultaneously.

This means, for instance, that the device can switch a light on and off, or automatically switch it on and off after a certain pre-established time, simply on the basis of the command received.

The module is assembled on the DIN rail, inside the electric boards or junction boxes.

Functions

Each channel of the actuator can be configured with the Easy controller to carry out the following functions:

LOAD ACTIVATION AND DEACTIVATION

The actuator channel activates or deactivates the electrical load when it receives the ON/OFF commands sent, for example, from a contact interface or from a push-button panel configured as Cyclic ON/OFF switchover or Fronts management.

The green LED turns on when the relay contact is closed.

EXECUTION OF TIMED COMMANDS

The actuator activates the electrical load connected for a time set with the Switch-on time parameter, deactivating it when this time is up. This is the setting, for instance, for the stairs light. If, during the activation period, the actuator receives a new ON command with timer, time starts again from the beginning.

GENERAL DESCRIPTION

When an OFF command is received or when a scene is activates that includes the actuator OFF command, the relay is deactivated and the countdown cancelled.

The switch-off warning can be enabled with the Prewarning time parameter: in this case the relay opens briefly (the light turns off momentarily) when, at the end of the time set, there is the time left set by the parameter. It will thus be possible - if necessary - to send a new ON command with timer before the light turns off. The green LED turns on when the relay contact is closed.

EXECUTION OF PRIORITY COMMANDS

The actuator switches the relay to the (ON or OFF) state transmitted by the device (contact interface) that sends the priority command.

Until it receives a command to stop forcing, the actuator ignores all the other commands received including those from the front push Buttons.

If no other commands are received, when forcing is finished the actuator returns to the state before forcing was activated. Otherwise, it will return to the state corresponding to the last command received.

The green LED turns on when the relay contact is closed.

SCENE MANAGEMENT

Each actuator channel can store and execute up to 8 scenes, each scene associated with the ON or OFF status of the relay. It is not possible to associate a scene with a timed activation.

To associate an actuator status with a scene it is necessary to control the output of the status required (ON/OFF) prior to storing.

The green LED turns on when the relay contact is closed.

INSTALLATION

ATTENTION: the device must only be installed by qualified personnel, observing current regulations and the guidelines for KNX installations.

Recommendations for installing the KNX

1. The length of the bus line between the actuator and the power supply must not exceed 350 metres.
2. The length of the bus line between the actuator and the furthest away KNX device must not exceed 700 metres.
3. To avoid unwanted signals and overvoltages do not use ring circuits.
4. Keep a distance of at least 4mm between the individually insulated cables of the bus line and those of the electricity line (figure C).
5. Do not damage the electrical continuity conductor of the shielding (figure D).

ATTENTION: The bus signal cables that are not used and the electrical continuity conductor must never touch any live elements or the earthing conductor!

Assembly on the DIN rail

Mount the 4-channel actuator on a 35mm DIN rail in the following way (figure E):

1. Insert the upper device coupling in the DIN rail.
2. Turn the device and lock it on the DIN rail, using the fixing tab.

Electric connections

ATTENTION: disconnect mains voltage before connecting the device to the mains!

Figure B shows a diagram of the electrical connections.

1. Connect the red wire of the bus cable to the red terminal (+) of the terminal and the black wire to the black terminal (-). Up to 4 bus lines can be connected to the bus terminal (same coloured wires on the same terminal) (figure F).
2. Insulate the shield, the electrical continuity conductor and the other white and yellow wires of the bus cable (if a 4-conductor bus cable is being used), that are not necessary (figure D).
3. Insert the bus terminal in the device's pins. The correct insertion direction is determined by the fixing guides. Insulate the bus terminal with the cover to be screwed onto the device.

The cover guarantees the minimum separation distance of 4mm between the power cables and the bus cables (figure G).

1. Connect the loads to the relevant supplied screw terminals, making sure the current limits specified in the Technical Data are not exceeded. Insert the terminals in the actuator output connectors, and check they are correctly inserted (figure H).

Using the local command push-button

With the local command push Buttons (figure A) you can control cyclic ON/OFF switching over, reversing the status of the relay each time it is pressed. If a priority command is active, the local commands will not be executed.

ATTENTION: the local command push Buttons will only work if BUS voltage is present.

Behaviour of supply fall/reset on the bus

If BUS voltage drops below 18 V dc for more than 1,5 ms the actuator, with the factory default settings, will not carry out any changes to the status of the output contacts. The behaviour of the outputs when BUS voltage drops can be configured in the following way.

Configuration mode input:

• press the programming key: the red programming LED turns on
• press the local command push Buttons 1 and 4 simultaneously for at least 3 seconds
• wait until the 4 LEDs blink once

When you are in the configuration mode, the contacts of all the channels are opened and the LEDs show the current configuration status of each single channel, as per the table.

CHANNELS 1..4 LED4 CHANNEL STATUS WHEN VOLTAGE DROPS
Off Open
On Closed
Blinking No change

The setting of each single channel can be changed with its relative key, so as to scroll all the configurations available in sequence.

IN SERVICE

Configuration mode output:

• to save the new settings: press the programming push-button. The programming LED turns off;
• to exit without saving the settings: wait 10 seconds (from when you last pressed a button). The end of the configuration mode is signalled when the programming LED turns off.

When you exit the configuration mode the status of the channels before accessing the procedure is restored.

In this configuration phase, the messages from the bus are ignored (they are managed when configuration is exited).

When bus voltage is restored the contacts stay in the state they were in when voltage dropped.

Maintenance

The device does not require any maintenance. Use a dry cloth if cleaning is required.
