MASTER 2.0
All-in-one mains
paralleling unit
with integrated PLC
• Compact “all in one” module
• Fully compatible with GENSYS 2.0 and
most analog lines modules
• Internal logic sequences, programmable
by equations with the Easy PLC software
• Isolated ports: RS485, 2 CAN bus
• SD card reader, Ethernet
• All mains paralleling sequences management
• Large, multi-function graphic display
• Embedded web site

The Master 2.0 is a power plant controller
for gensets in parallel with one or several
mains.

This “all-in-one” unit includes all necessary
functions:
•tMulti mains management
•tThree phase mains failure detection
•tElectrical protection
•tElectrical parameters display
•tManual and automatic paralleling with
mains (frequency, phase and voltage)
•tkW power management with several
modes:
ͳͳ No break change over with load
transfer
ͳͳ Permanent paralleling in base load
ͳͳ Permanent paralleling in peak
shaving mode
•tPower factor control when paralleling
with mains.
•tDyn11 capabilities
(HV phase compensation)
•tAnalog control for all load sharing modules.

PROGRAMMABLE EQUATIONS
The Master 2.0 controller is a real PLC unit where equations and sequences can be programmed directly by the
user with text editor software or Easy PLC software.

INPUTS / OUTPUTS WITH NO LIMITS
The number of input/outputs that can be added is one of
the most important on the market. Extension modules (DIN
rail mounting) can be added on the CAN bus.
You can add both digital and analog inputs/outputs.

MAINS AND POWER PLANT ELECTRICAL PARAMETERS
Not only the Master 2.0 parallels the power plant with
mains, it also protects the power plant and measures electrical parameters.

APPLICATIONS
•t Constant generating set power (base load) :
In this mode, the generating sets provide constant power.
Mains power varies according to the load.
•t Constant mains power (peak sharing) :
In this mode, the mains power (imported or exported) remains constant. The generating sets vary their power according to the load.
•t Power plant control with several mains:
•t 1 Master 2.0 per mains
•t No-break change-over with load transfer.
•t Transfer-switch unit control.
