Disabled Disabled Both controllers are in normal operation.
Switching of gen-sets
Switching of gen-sets is based on their Running Hours (page 471). The time how long the gen-set is running is
adjusted via setpoint Running Hours Max Difference (page 239). When difference of Running Hours (page
471) between gen-sets is bigger then value adjusted in this setpoint, load is transferred from first gen-set to
second gen-set. First gen-set is supplying the load until second gen-set is in running state. Then the GCB of first
gen-set is opened. From this moment timer Transfer Delay (page 241) counts down. When it counts down,
GCB of second gen-set can be closed.
Note: Value of Running Hours (page 471) can be modified by setpoint Running Hours Base (page 240).
This setpoint can add or remove additional running hours to value from statistics. This modified value of running
hours is used in dual operation function.
Note: In case that both gen-sets have the same running hours, Master controller has higher priority.
Note: Switching of gen-sets can be inhibit by setpoint Swap Gen-sets (page 240) or by binary input DUAL
SWAP GEN-SETS (PAGE 526).
Note: Priority of gen-set can be changed by binary input DUAL TOP PRIORITY (PAGE 526). In this case running
hours values are not used to decide, which gen-set should start.
Dual operation adjustment
Prepare two InteliLite AMF25 or two InteliLite MRS16 controllers with CM-RS232-485 modules
Copy the identical configurations to both of them
Use wiring with mechanical/electrical interlock between all breakers (mechanical interlock is preferred)
Switch both controllers to OFF mode to prevent automatic or remote start
Adjust setpoints COM1 Mode (page 343) or COM2 Mode (page 345) (depends on prefered communication
line) to DualMaster on first controller and Dual Slave on second controller
Interconnect communication terminals on CM-RS232-485 modules
Adjust setpoint Running Hours Max Difference (page 239) on Master controller
Adjust setpoints Running Hours Base (page 240) on both controllers if running hours change is needed for
dual operation
Adjust additional function of dual operation - Master Error Protection (page 241), Slave Error Protection
(page 241) and Swap Gen-sets (page 240) setpoints
