Power plant paralleled with mains using MASTER 2.0 or
GCR
Figure 30 - Power plant paralleling with mains
This application requires additional modules to manage the mains power supply. Additional modules can
be MASTER 2.0 (recommended) or GCR+CPA (not recommended for a new installation). MASTER 2.0 uses
all-digital technology whereas GCR uses analogue load share lines (sometimes called Parallel Lines).
With this setup, base load or peak shaving regulation can be selected, depending on your settings. In base
load mode, GCR doesn't require CPA.
This chapter is a basic overview. Full MASTER 2.0 functions can be found in the MASTER 2.0 technical
documentation.

Table 15 - Paralleling with mains configuration
(1) On the CAN bus point of view, MASTER 2.0 is equivalent to a GENSYS unit, so it must be identified by a number. For example, the use of
one MASTER 2.0 gives a maximum of 31 generators.
(2) Mains paralleling mode is fixed to « No changeover » when a single GENSYS 2.0 is used together with one or more MASTER 2.0.
