3.3. Bay view
Menu > Bay view
Bay view
ELF software tool allows configuration of the bay view,
customized to user’s needs. There is no need therefore to
visualize the whole bay, only its individual components,
such as state of the CB. Bear in mind, however, that
inserting in the bay view of e.g. earthing switch that is not
there in the actual bay, shall result in displaying it as not
monitored.
Control activates the mechanism of switch control.
Activation of this option marks the main switch.
Another switch may be selected with the , keys.
The switches which cannot be controlled may not be
selected and marked.
After selection of the required switch and pressing the
key the Control window opens in which required switching
operations may be selected from the list and confirmed
with the key.
After selection of the required operation it will be executed
or “not available” message displayed.
The switches may be operated also in the Switches window or by means of a User command.

programmable signal LEDs installed on device front panel.
Diodes are configured by means of ELF program, in the tab
Logic; configuration consists in assigning a signal from the
system, algorithm or automatic function to specific LED.
Active state of the signal results in illumination of LED.
Descriptions of signalization diodes are defined by editing
the text assigned to given diode and are shown on the
display. The mark in front of the description text
corresponds with the diode colour illumination.

2) date and time –the events are tagged with 1 ms
resolution time tags,
3) descriptive text –displayed in one or two lines,
4) up to 5 parameters, e.g. current value at protection
stripping (the parameters may be accessed by selecting
the Details context key)
The logged events may be filtered for displaying in regard
of their types. Having selected the Filter context key a
window opens in which event types to be displayed may be

Menu > Alarms
Alarms
MUPASZ 710 plus implements a series of switch bay
protection algorithms. In order to facilitate reading of
operating state of algorithms, the software of MUPASZ
710plus device is fitted with the function of displaying
aggregated information on states of all algorithms
implemented in the active profile.
In the Alarms window aggregated information on alarms,
locks and tripping is displayed.
The DELETE key deletes all signaling and displays
a relevant message.
If the cause of signaling is still active it will not be
cancelled. First the cause should be removed and then the
signaling cancelled.
Signaling may be selectively cancelled by means of the , , key.
An adequate User command on the logic scheme may be used to cancel signalization after adaptation.

Autonomous control –control without
participation of the device (CB is controlled by external
devices).
See chapter 3.9.1.1 Edition of parameters.
Before setting the control mode one should check if the intended mode is allowed in settings. - Menu >
Management > Settings > Settings X > Control group > Selection of control.
If in the bay operation logic scheme the control mode selection is done via binary inputs then selection
of the control mode via the user interface is disabled.
3.8.2. User commands
Menu > Control > User commands
ELF software tool allows the user to define own
commands which activate logic functions from the
device menu level.
Commands are configured by means of ELF program, in
the tab Logic; configuration consists in entering the
CMD_USER block and connecting its output signal to the
block of the function it is to activate. Selecting the
command from device menu shall activate the
instruction resulting from the logic.
User commands may be used to control the switches, cancel signaling, activation of algorithms or
execution of any user designed function present on the device logic scheme.

in separate menu branches.
After pressing the Factory context key all parameters in
a given set of settings may be restored to factory values.
The Cancel command opens again the window with
configuration of settings in the edited set. The Factory
command will be executed or information displayed that
the command cannot be executed. Additionally, a relevant
event will be logged in the Event log.
