RSU (Remote Setting Utility)
This utility is used to set the protection functions and alarms for each Compact and
Compact NSX device.
After connection to the network and entry of the circuit breaker Modbus address,
the software automatically detects the type of trip unit installed.
There are two possible operating modes.
Off-line with the software disconnected from the
communication network
For each selected circuit breaker, the user can do the following.
Determine the protection settings
The settings are carried out on a screen that shows the front of the trip unit.
The Micrologic setting dials, keypad and screen are simulated for easy use of all
Micrologic setting functions.
Save and duplicate the protection settings
Each configuration created can be saved for subsequent device programming. It can
also be duplicated and used as the basis for programming another circuit breaker.
On-line with the software connected to the network
Similarly, for each selected circuit breaker, the user can do the following.
Display the current settings
The software displays the trip unit and provides access to all settings.
View the corresponding protection curves
A graphic curve module in the software displays the protection curve corresponding
to the settings. It is possible to lay a second curve over the first for discrimination
studies.
Modify settings in a secure manner
There are different levels of security:
b
password: by default, it is the same for all devices, but can be differentiated for
v
each device
locking of the Modbus interface module which must be unlocked before the
v
corresponding device can be set remotely
maximum settings limited by the positions of the two dials on the trip unit.
v
These dials, set by the user, determine the maximum settings that can be made via
the communication system.
Settings are modified by:
b
either direct, on-line setting of the protection settings on the screen
v
or by loading the settings prepared in off-line mode. This is possible only if the
v
positions of the dials allow the new settings.
All manual settings made subsequently on the device have priority.
Program alarms
Up to 12 alarms can be linked to measurements or events.
b
two alarms are predefined and activated automatically:
b
Micrologic 5: overload (Ir)
v
Micrologic 6: overload (Ir) and ground fault (Ig)
v
thresholds, priorities and time delays can be set for 10 other alarms. They may be
b
selected from a list of 91 alarms
Set the outputs of the SDx relays
This is required when the user wants to change the standard configuration and
assign different signals to the 2 outputs of the SDx relay.
RCU (Remote Control Utility)
The RCU utility can be used to test communication for all the devices connected
to the Modbus network. It is designed for use with Compact NSX, Compact,
Advantys OTB and Power Meter devices. It offers a number of functions.
Mini supervisor
Display of I, U, f, P, E and THD measurements for each device, via navigation.
b
Display of ON/OFF status.
b
Open and close commands for each device
A common or individual password must first be entered.
When all functions have been tested, this utility is replaced by the supervision
software selected for the installation.
Two utilities, RSU and RCU, are available to assist in
starting up a communicating installation.
They can be downloaded from the Schneider Electric
internet site and include a "Live update" function that
enables immediate updating.
