Product version: 1.0

17. Local HMI

The IED is equipped with a four-line liquid crystal
display (depending on the chosen font and
language, more or fewer lines might be visible).
The display is designed for entering parameter
settings of the protection and control functions. It
is also suited for remotely controlled substations
where the IED is only occasionally accessed
locally via the front panel user interface.
The display offers front-panel user interface
functionality with menu navigation and menu
views. Depending on the standard configuration,
the IED displays the related measuring values.
The LHMI includes a push button (L/R) for local/
remote operation of the IED. When the IED is in
the local mode, the IED can be operated only by
using the local front panel user interface. When
the IED is in the remote mode, the IED can
execute commands sent from a remote location.
The IED supports the remote selection of the local/
remote mode via a binary input. This feature
facilitates, for example, the use of an external
switch at the substation to ensure that all IEDs
are in the local mode during maintenance work
and that the circuit breakers cannot be operated
remotely from the network control center.

18. Mounting methods

Using appropriate mounting accessories, the
standard IED case for the 611 series IED can be
flush mounted, semi-flush mounted or wall
mounted. The flush mounted and wall mounted
IED cases can also be mounted in a tilted position
(25°) using special accessories.
Further, the IEDs can be mounted in any standard
19" instrument cabinet by means of 19" mounting
panels available with cut-outs for one or two
IEDs. Alternatively, the IED can be mounted in 19"
instrument cabinets using 4U Combiflex
equipment frames.
For routine testing purposes, the IED cases can
be equipped with test switches, type RTXP 18,
which can be mounted side by side with the IED
cases.
Mounting methods:
• Flush mounting
• Semi-flush mounting
• Semi-flush mounting in a 25° tilt
• Rack mounting
• Wall mounting
• Mounting to a 19" equipment frame
• Mounting with a RTXP 18 test switch to a
19" rack
Panel cut-out for flush mounting:
• Height: 161.5 ±1 mm
• Width: 165.5 ±1 mm
