Notes:
[E1902] = stability of de-drooping (only activated in the master GENSYS 2.0). Adjust to recover 1Hz within 5
sec.
[E1476] = 0  Inhibition of central frequency.
[E1476] = with a high value, response time will be slower (recommended default value =2)
[E1901] = Load sharing integral, is only active on the slave GENSYS 2.0 units.
[E1102] = Global gain of load sharing is obtained by multiplying the PI and the central Hz gain.
[E2739] = 1  I am the master (I control the frequency).
[E2739] = 0  I am a slave (I share load using the integral)
13.1.3 GCR synchronization & mains paralleling
When using the central frequency (de-drooping) function and paralleling with the mains
using an analogue bus, the central frequency has to be inhibited during synchronization.
The following equations should be added in level 1 or 2 if the synchronization bus is used
(terminal 42 of GCR, terminals G1 & G3 of GENSYS 2.0):
@ ******************************************************;
@ digital input 1(E2006) is closed during mains synchronization;
@ mains breaker feedback is connected to terminal J1 ;
@ Don’t forget to allow parameter E1476 and E1020 to be ;
@ modifiable by modbus and equations ;
