4.2.4.4 Energy saving mode
The device has an energy-saving mode to save electrical energy during operation. If the
function is used, the device switches to the energy saving mode after a preset time without
operation or switches to a separate object controlled by an external telegram (see "Activating
energy saving mode"). In the energy saving mode, essential operation and display functions of
the device are switched off. The Status LED and operation LED are then without any function.
The energy saving mode can be deactivated through an operation or by a special telegram (see
"Deactivating energy saving mode"). Afterwards, the device is fully functional again.
Activating energy saving mode
The device has two different activation options for switching the pushbutton sensor to the
energy saving mode. These can either be combined together or used separately. Firstly, the
device can be set to the energy saving mode by a group telegram via a communication object
designated for this purpose. To do this, the telegram polarity that triggers the activation of the
energy saving mode must be defined in the ETS.
Secondly, it is possible to switch to the energy saving mode automatically if no operation occurs
on the device within a defined time period. The time for this case is defined in the ETS. Each
operation restarts the time for activating the energy saving mode.
When energy-saving mode is active, no telegram evaluations or transmissions take place via
the communication objects of the device (exception: "TSM/TSEM - energy-saving mode"
object). In consequence, no state changes can be added for operation and display functions, for
as long as energy-saving mode is activated.
If the energy saving mode is to be activated via the communication object and an operation
takes place on the device at this time, the activation of the energy saving mode is then delayed
until the end of the control operation. This ensures that the operating functions are still executed
properly until the end and all necessary telegrams are transmitted to the bus.
Energy-saving mode is never activated while programming mode is active.
i
On activation of energy-saving mode, all the LEDs of the device are switched off under
forced control. Display functions for Status LEDs, which were active before energy-saving
mode (e.g. status displays), are first executed unchanged when energy-saving operation is
deactivated. New control of the objects of the display functions must then take place for the
Status LEDs to signal a current status, or possibly a different one.
i
The communication object of the energy saving mode can either be used just for activation,
or alternatively just for deactivation, or if required, for the combined activation and
deactivation, too. In all cases, the telegram polarity can be configured in the ETS. Only
different polarities can ever be configured (e.g. "0" = mode inactive / "1" = mode active ) for
the combined activation and deactivation.
i
Any activation attempts of the energy saving mode are ignored while the programming
mode of the device is active. The device stores the activation attempt and executes the
energy saving mode once the programming mode is terminated. If the device is
programmed by the ETS (physical address and/or application program) in an active
programming mode, the device does not then execute the energy saving mode
automatically at the end of the programming operation.
Deactivating energy saving mode
The device has two different options for deactivation of energy-saving mode, which can be
optionally combined. Firstly, it is always possible to deactivate energy-saving mode
automatically, as soon as the device is operated. On the other hand, deactivation can also take
place by a group telegram via the communication object designated for this purpose. For this
purpose, the telegram polarity that triggers the deactivation of the energy saving mode must be
defined in the ETS.
