Function Keys F1 to Fx as Control Keys

As described in Chapter “Configurable Function Keys (Function Group F_KEY)” function keys [F1] to [Fx] may be configured as control keys (for [F1] e.g. at F_KEY: Fct. assignm. F1).

In this case different rules apply to checking the password (see Chapter “Configuration of the Function Keys F1 to Fx”) and the configuration to “Key/Switch” is ignored.

In case the control functionality is desired then each of the following four control commands, should be assigned to a function key. The particular selection of the four function keys out of the available six, however, does not matter.

▪	MAIN: Local/Remote key The “Local/Remote” control command is effective only in the bay panel except where a binary signal input has been configured for this function. Depending on the configured functionality, the “Local/Remote” command toggles either between “Remote” and “Local” control, or between “Local/Remote” and “Local” control. (The parameter LOC: Fct. assign. L/R key may be set either to R <-> L or to R & L <-> L and will then define which of the two switching modes is active.) If the “Local/Remote” command is configured such that it will switch from “Remote” control to “Local” control, then this can only occur if the password has first been entered at LOC: Password L/R. Switching from “Local” to “Remote” control will occur without checking the password. (See also Chapter “Selection of the Control Point”.)
▪	MAIN: Device selection key This selection command is effective only in the bay panel and only if “Local” control is activated. If local control has been selected, pressing the selection key selects the switchgear unit to be controlled. This selected external device is marked on the text display HMI with the flashing symbol “>” in front of the external devices’ designation text.
▪	MAIN: Device OPEN key The OPEN command is effective in the bay panel only. Pressing the key assigned to this function controls the selected switchgear unit – taking into account the interlock equation – to assume the “open” status.
▪	MAIN: Device CLOSE key The CLOSE command is effective in the bay panel only. Pressing the key assigned to this function controls the selected switchgear unit – taking into account the interlock equation – to assume the “closed” status.
