condition. The return time is restarted when any of the control keys is pressed.
6.11.3.2 Forced Return
The return described above can be forced from the local control panel by first
pressing the “up” key and then holding it down while pressing the CLEAR key.
It is important to press the “up” key first and release it last in order to avoid
unintentional deletion of stored data.
Even when the change-enabling function is activated, not all settings can be
changed. For some settings it is also necessary to disable the protective function
(MAIN: Device on-line, menu tree: Par/Func/Glob/MAIN). Such settings include
the configuration settings, by means of which the device interfaces can be
adapted to the system. The following entries in the “Change” column of the
“Telegram Documentation” (part of the separately available
“DataModelExplorer”) indicate whether values can be changed or not:
●
“on”: The value can be changed even when the protective function is
enabled.
●
“off”: The value can only be changed when the protective function is
disabled.
●
“–”: The value can be read out but cannot be changed.
The device is factory-set so that the protective function is disabled.
