AMF settings: RetFromIsland = AUTO, it starts break transfer of the load back to Mains if it is enabled
by the setpoint AMF settings: ReturnWithIntr .
N
OTE
:
The settings of the controller must allow the Test on Load function to transfer the load to the gen-set
group. If this is not allowed (e.g. SysBaseLoad is 0 kW), the system will not transfer the load.
7.3 Process Limitation
This chapter brings overview of process limitations in AUT mode (whole system in AUT mode, if there
are e.g. gen-set controllers in MAN mode, other settings conbinations may be used). There are many
possibilities how to set the setpoints related to the process limitation, nonetheless there are several
recommended settings (for whole system in AUT) that are shown the table below with short
description of the function.

YES YES BOTH YES NO
- Island and Parallel operations are possible.
- Transfer with synchronization from Island to
Parallel and from Mains to Parallel are enabled
- Gen-sets will be started when the Mains fails.
- Gen-sets will first synchronize on the bus before
synchronizing via MGCB
YES YES BOTH NO NO
- Island and Parallel operations are possible.
- Transfer with synchronization from Island to
Parallel and from Mains to Parallel are enabled
- Gen-sets will not be started when the Mains
fails.

- Island and Parallel operations are possible.
- Transfer with synchronization from Mains to
Parallel is enabled (Island to Parallel N/A)

synchronizing via MGCB
YES YES NONE YES YES
- Island and Parallel operations are possible.
- Transfer with synchronization via InteliMains is
not available
- Gen-sets will be started when the Mains fails.
- Gen-sets will synchronize directly to the Mains
(MGCB already closed) , i.e. synchronization
transfer from Island to Parallel
