master/slave controller. Both controllers will be switched to normal
operation.

There will be communication fail (it is necessary to have master and
slave to establish communication line) - there will be active alarm
Dual Operation Fail (page 665)
. This alarm will be active on
master/slave controller. Both controllers will be switched to normal
operation.
Disabled
Disabled
Both controllers are in normal operation.
Switching of gen-sets
Switching of gen-sets is based on their
. The time how long the gen-set is running is
adjusted via setpoint
Running Hours Max Difference (page 239)
. When difference of
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
counts down. When it counts down,
GCB of second gen-set can be closed.
Note:
Value of
can be modified by setpoint
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
or by binary input
Note:
Priority of gen-set can be changed by binary input
. 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
or
(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
on both controllers if running hours change is needed for
dual operation
Adjust additional function of dual operation -
Master Error Protection (page 241)
and
setpoints
