5.5.7 Dual Operation
Dual operation - MRS
Dual operation MRS consists 2 gen-sets. Principle of dual operation is in switching the gen-sets in supplying of
load when REMOTE START/STOP (PAGE 536) is activated on Master controller (on slave controller this LBI has
no function in Dual Operation). Each controller measures its gen-set. Interlock between all breakers (GCB1 and
GCB2) is required. If there is fail of one gen-set, second gen-set will take the load.
IMPORTANT: Dual operation works only in AUTO mode.
IMPORTANT: Dual operation is in fail also during process of adjustment of setpoints.
IMPORTANT: It is not possible to use Auto Run option in Exercise timers with dual operation.

Communication
Communication is establish on RS232 or RS485 communication line. Plug-in module CM-RS232-485 is
required. Communication line is selected via setpoints COM1 Mode (page 343) or COM2 Mode (page 345).
There are options DualMaster and DualSlave. These options adjust, which communication line is selected and
which role controller has in Dual Operation.
IMPORTANT: For correct communication it is necessary to have one Master and one Slave
controller on the same communication line.
IMPORTANT: There are no shared setpoints. It is necessary to have the same settings of engine
timers in both controllers.
In case of communication fail between controllers, alarm Dual Operation Fail (page 665) is activated. This
alarm is activated on both controllers. Both controllers are switched to normal operation.
