 Loss of voltage
 Each GENSYS 2.0 is ordered to start.
 All breakers (CB1, CB2, CB3 & CB4) close as ordered by GENSYS 2.0.
 DG1, DG2, DG 3, & DG4 start.
 All generators reach the speed defined by the [E1896] setting (CANBUS synchronization).
 There is a residual voltage of 80V.
 All C1outputs close simultaneously to activate excitation (after dialogue between GENSYS 2.0
units).
 The nominal voltage is reached immediately at the same time on all generators.
 The plant is available to take up required load.
 Breakers are closed when engine is stopped.
 There is a residual voltage of 80V.
8.5.2 Advantages
 Full plant availability in less than 10 seconds.
 Gradual magnetization of the step-up transformer (no transient short-circuit).
8.5.3 Configuration
 One GENSYS 2.0 per generating set.
 CAN bus must be connected between GENSYS 2.0 units.
 An "Excitation" output (e.g. exit C1) must be configured on each GENSYS 2.0 unit.
 Generator breaker must be powered by 24VDC (so as to close without AC).
 In the Setup menu / General Central / sync mode.[ E1177] must be set as "Static stop".
 The value of the maximum excitation rpm is set with [E1896] (default: 97%).
 The alternators must be identical.
 Each GENSYS 2.0 must be equipped with a speed sensor (magnetic sensor / Pick-up).
