6 Local Control (HMI)
6.1 Local Control Panel (HMI)
Switchgear installed in the bay can be controlled from the local control panel
(HMI). All the data required for operation of the protection device is entered from
the local control panel, and the data important for system management is read
out there as well. The following tasks can be handled from the local control
panel:
●
Controlling switchgear units
●
Readout and modification of settings
●
Readout of cyclically updated measured operating data and logic status
signals
●
Readout of operating data logs and of monitoring signal logs
●
Readout of event logs after overload situations, ground faults, or short
circuits in the power system
●
Device resetting and triggering of additional control functions used in
testing and commissioning
Control is also possible through the PC interface. This requires a suitable PC and
a specific operating program.
