RSU (Remote Setting Utility)
This utility is used to set the protection functions and alarms for each Masterpact 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

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

Modify settings in a secure manner
There are different levels of security:

corresponding device can be set remotely
maximum settings limited by the positions of the two dials on the trip unit.

These dials, set by the user, determine the maximum settings that can be made via
the communication system.

or by loading the settings prepared in off-line mode. This is possible only if the

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.

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, Masterpact,
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

Display of ON/OFF status

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.
