9.5.5 Check or improve synchronization
 Check than breaker control is disable. (Unplug connector “E”)
 Check Voltage on bus bar.
 Start the generator in [Manu] mode by pressing [Start] button.
 Press the generator breaker [0/I] key.
 Check that you are now in synchronization mode using the information screen key [i].
 When the GENSYS 2.0 is ready to synchronize (synchroscope to noon), check that the phases match
in upstream and downstream of the breaker. (i.e low voltage difference between phase n°1
generator and phase n° 1 bus, and so on for the other phases). If one of these checks is not correct,
you have to check the wiring of the generator voltage and mains voltage.
 When you are sure there is no wiring problem, stop the generator by pressing [Stop] button.
 Activate the breaker control. (Plug connector « E »).
 Start the generator in [Manu] mode by pressing [Start] button.
 Press the generator breaker [0/I] key.
 The generator must be paralleled without difficulties.
Note : If the generator sweep around the synchronization point or if the synchronization is too slow, adjust
the synchronization gain in the menu « Configuration/Synchronization/Phase synchro »
Method to set the synchronization PID:
If the point oscillates quickly around the top syncrho : decrease the gain
If the point oscillates slowly around the top syncrho and is hard to stabliz : decrease the integral
If the point rotates slowly or quickly : increase the integral, then the gain if necessary.
9.5.6 Check or improve load sharing / kW regulation
For this application, check the stability of KW and kVAR regulation.
After the mains breaker closes, check load ramp (P=CsteGPID) configuration in the “Active Power
Regulation” menu.
If the genset goes into reverse power or stays at low load during the ramp time (E1151) increase
P=CsteGain in the “Active Power Regulation” menu.
At the end of the ramp time, the GENSYS 2.0 will swap to “Kw Sharing Gain”.
You can now set your load sharing gain and check the settings which depend on load impact (test with load
bench, for example).


 For this point, it’s important to check the wiring of the power lines (current transformer …)
 After paralleling, the GENSYS2.0 start a power regulation according to his configuration :
o Load sharing if paralleling between generators
o Constant kW setpoint on generator if GENSYS2.0 is set as Permanent with base load
o Constant kW setpoint on mains if GENSYS 2.0 is set as Permanent with Peak shaving
o Droop
