Button operation and indication functions

The gateway offers manual operation to control the switching status and brightness of all programmed luminaire groups and single devices. The keypad with function buttons and status LEDs on the front of the device can be used to set the following operating modes. Manual operation is possible separately for DALI systems 1 and 2 with the 2-gang device variant.

Bus mode: operation by push-button sensors or other KNX devices,
Temporary manual operation mode: manual operation locally with keypad, automatic return to bus control,
Permanent manual operation: local manual control with keypad.

The operating modes can be enabled or disabled by parameter settings in the ETS.

In manual operation, the groups or single devices cannot be controlled via the KNX.

Manual operation is possible only when the mains voltage supply to the gateway is switched on. In the delivery state of the DALI gateway, manual operation is enabled. In this unprogrammed state, all connected DALI operating devices of both DALI systems can be controlled using the broadcast function to enable fast function checking of the connected electronic ballasts (e.g. on the construction site).

In manual operation mode, bus operation can be disabled via a telegram. Manual operation mode is terminated on activation of the disabling function.

Only the switching state (ON/OFF) and the brightness value (dimming) can be controlled by manual operation. The colour temperature of a group or single device cannot be changed. In the case of colour-controllable DALI operating devices, the colour is set to the maximum colour value (RGB: #FFFFFF) and, if necessary, also to the maximum white value (#FF) during manual operation, but only if the current colour corresponds to the state "#000000" (black) and the optional white value corresponds to "#00". This ensures that manual brightness control by manual operation can be recognised by the user.

The manual control and the status display do not analyse DALI sensors.

Controls and indicators for manual control

(1)	button – Manual control
(2)	LED – On: Continuous manual operation active LED – Flashing: Temporary manual operation is active
(3)	button – Switch on or increase brightness
(4)	LED – On: DALI device or a DALI group switched on, Brightness 1...100%
(5)	button – Switch off or reduce brightness
(6)	LED – On: DALI device or a DALI group switched off, Brightness 0%
(7)	Button ALL OFF – Switch off all DALI devices
(8)	Seven-segment display for indication of the number (1...16, 1...32) of a DALI group (8a) or the short address (1...64) of a single device (8b) selected by manual operation. In bus mode, there is no indication of the group number or short address. In addition, to indicator additional information: - -: signals DALI initialisation phase, delay after ETS programming operation / mains voltage return or temporary status indication. bc: indication during manual operation in broadcast mode (unprogrammed state, central control). Er: indication of an impermissible external voltage at the DALI device connection terminals (e.g. mains voltage connected). DALI gateway without function. The device is ready for operation again as soon as there is no longer an error. db: a high telegram load has been detected in the DALI system signalled by the LED (9). This high load can lead to disturbed operation (noticeable delays, telegram loss). LE: signals automatic device replacement. E: signals an error during automatic device replacement.
(9)	LED of the active DALI system lights up in manual operation or after pressing the change-over button (only with "2fold" device variant)
(10)	Change-over button for DALI systems 1 and 2 (only with "2fold" device variant)

If the indicator (8) shows bc (broadcast operation), all devices of a DALI system are controlled jointly. This is done in the following operating conditions.

The device is not programmed
Set to master control in the KNX configuration
In bus mode, broadcast is additionally configured and active

When operating the DALI devices with the keypad, the device differentiates between short and long actuation.

Short: Pressing for less than 1 second
Long: Pressing for between 1 and 5 seconds

Change-over system 1 and system 2

In the case of the "2fold" device variant, the change-over button (10) can be used to switch between an operation of DALI systems 1 and 2. This is possible either while the device is in operation or during active temporary or permanent manual control.

Only the selected DALI system is ever operated via the keypad of the manual control. The LEDs (9) signal the DALI system effective for manual control.

The change-over button (10) has no function during temporary status indication.

The LEDs (9) light up for the duration of the initialisation phase of the two DALI systems (after an ETS programming operation or after the mains voltage returns). The initialisation phase of the two systems may be of different length.

Switching on temporary manual operation

Operation using the button field is programmed and not disabled.

Press the (1) button briefly.

Indicator (8) shows the first group number, short address or bc, LED (2) flashes. With the "2fold" device version, the LED (9) of the last operated DALI system lights up.

After 5 seconds without a button actuation, the device returns automatically to bus mode.

Switching on/off the permanent manual operation

Operation using the button field is programmed and not disabled.

Press the (1) button for at least 5 seconds.

LED (2) is illuminated, indicator (8) shows the first group number, short address or bc.. Permanent manual operation is switched on. With the "2fold" device version, the LED (9) of the last operated DALI system lights up.

- or in case of repeated actuation for at least 5 seconds -

LED (2) is off, indicator (8) is off, bus mode is switched on.

Operating DALI devices

The device is in temporary or permanent manual operation.

Press the button (1) briefly as many times as necessary until the desired DALI group number or short address is indicated (8).

Operate output with (3) button or (5) button.
Short: switch on/off.
Long: dim brighter/darker.
Release: Stop dimming.
The LEDs (4) and (6) indicate the status.

The numbers of the available DALI groups (8a) are indicated (8) first, and then the short addresses of the single devices (8b). If configured, bc for Broadcast appears at the beginning.

After a device reset (mains voltage return, ETS programming operation), the switching state "OFF" may be signalled initially, regardless of the actual switching states of the DALI operating devices. In this case, the switching status is displayed correctly only after manual control. This must be observed in particular in broadcast mode when individual operating devices of the DALI system are switched on before manual control is carried out. The status LEDs then show the command of the last broadcast manual control.

Switch off all DALI devices

The device is in permanent manual operation.

Press the ALL OFF button (7).

Disabling/enabling individual DALI devices or groups

The device is in permanent manual operation and the lock is released.

Press (1) button briefly as many times as necessary until the desired DALI number is indicated (8).

Press the (3) and (5) buttons simultaneously for at least 5 seconds.

The selected DALI number flashes on the indicator (8).

DALI device or group is blocked.

- or in case of repeated actuation -

The indicator (8) no longer flashes.

DALI device or group is enabled.

Activate bus mode (see section Switching the permanent manual operation on/off).

DALI devices blocked via manual control can be operated in manual operation.

Performing a DALI device replacement

After starting the automatic device replacement, the DALI gateway is able to check a DALI system of the previously operated DALI operating devices for completeness. If, for example, a defective electronic ballast was removed by an installation engineer and replaced by a new one, the DALI gateway is able to program the new electronic ballast with the programming data of the failed electronic ballast. This makes it possible to replace a failed DALI operating device by a simple operation on the device and without any modification work in the ETS.

When using the automatic device replacement, only operating devices of the same DALI type can be interchanged! If operating devices of another type are to be used, full DALI commissioning must be carried out using the ETS.

Automatic device replacement cannot be applied to DALI sensors.

Prerequisite: Only one DALI operating device per DALI system may fail and be replaced!

Prerequisite: The DALI gateway was programmed at least once before by the ETS.

Prerequisite: Automatic device replacement must be enabled in the ETS.

Prerequisite: It must be ensured that the bus and mains voltage remain switched on without interruption (also at all DALI operating devices) during the process.

Prerequisite: It is important that the DALI system has previously been fully commissioned by DALI commissioning.

Prerequisite: The device must be in bus operation (no manual operation active).

Press the and ALL OFF buttons simultaneously for at least approx. 10 seconds.

Automatic device replacement is activated. The length of the operation is dependent on the number of DALI operating devices in the system. When replacing the device, the 7-segment display signals LE (Learn). The disindicatorplay goes out after a successful replacement operation.

The automatic device replacement updates the configuration data (long address) of the replaced DALI operating device initially only in the gateway. To ensure that the change of the DALI configuration is permanently adopted in the ETS configuration, a DALI device search should be carried out again in the ETS (DCA) after executing one or more operations of the automatic device replacement. Through this, although no new operating devices are found, the DCA compares the DALI project planning data between gateway and ETS and saves the change in the ETS project. Only then may new programming operations of the application program be carried out.

If the application program is programmed with the ETS after an automatic device replacement without a subsequent new DALI device search in the DCA, the changes brought about by the device replacement will be lost. In this case, the DCA will display newly found operating devices that are actually not new in future device searches.

During device replacement, all the other functions of the DALI gateway are stopped. When replacing the device, the gateway tracks all the received bus states and evaluates the most recently tracked values (switching, dimming, values, scenes, central function, forced position function, disabling function) normally at the end of the automatic device replacement. An active forced position or disabling function is interrupted by device replacement and reactivated at the end of the replacement operation, if the functions have not been deactivated via the bus in the interim. The behaviour as at the beginning of the forced position or disabling function is not executed again.

Ensure that only one DALI operating device is replaced in the manner described. If multiple electronic ballasts fail (possibly no mains voltage is switched on) and have been replaced, then the electronic ballasts cannot be identified clearly by the gateway and not configured automatically. In this case, the DALI must be commissioned by the ETS again.

If an error occurred when replacing the device, the 7-segment display signals E (Error) for three seconds. Perform the operation again, taking the mentioned conditions and information into account. This signalling also takes place if automatic device replacement was activated, without having replaced a DALI operating device previously.

With the "2-gang" device variant, automatic device replacement can be carried out separately in the DALI systems. The systems do not influence each other.
