Terminal 6 Function
ATTENTION
Specific terminal 6 functionality require different input signals!
Parameter 211
Function term.6
----------------
Function of terminal 6
This parameter is used to assign a function to the terminal 6 discrete input. The fol-
lowing functions may be selected for the discrete input:
• Sprinkler operation
By de-energizing terminal 6, the sprinkler operation (critical mode) is enabled in accordance
with the functional description. Energizing terminal 6 terminates the sprinkler operation. For
a description of the sprinkler operation function refer to "Sprinkler (Critical) Operation" on
page 117).
Note: Load-dependent starting and stopping is not possible in sprinkler operation.
Attention: This is a negative logic function!
• Engine enabled
Terminal 6 has the same function as the STOP button: De-energizing terminal 6 prevents the
engine from starting and stops the engine if it is already running. Energizing terminal 6
enables the starting of the engine
Attention: Use of this function makes it possible to abort or prevent an emergency power
operation. An emergency power operation is not possible without enabling this function!
The enable engine function only operates when the GCP is in the AUTOMATIC operation
mode.
• Engine blocked
Energizing terminal 6 can prevent starting of the engine. If the engine is running due to an
active emergency power operation, energizing this discrete input will stop it. The engine-
blocked functionality is only possible when the GCP is in the AUTOMATIC operation
mode. The function of this mode is the opposite of the function of the "Engine enabled"
mode.
• Ext. acknowledgment
Alarms can be acknowledged externally by momentarily energizing terminal 6 in the STOP
and AUTOMATIC operation modes. In order to achieve additional acknowledgements, ter-
minal 6 must first be de-energized and then energized again. If terminal 6 is continuously re-
energized, any alarm messages generated after terminal 6 was energized will not be ac-
knowledged.
• STOP mode
By energizing terminal 6 the STOP mode is activated. If terminal 6 is de-energized, the op-
eration mode will revert back to the mode that was active prior to terminal 6 being ener-
gized.
• Start without CB
If the terminal 6 is energized, the engine starts. Synchronization is not performed and the
GCB is not closed (no closing to dead busbar). The GCB will only close if an emergency
power operation is enabled. After the mains return, the load is transferred back to the mains
according to the configured breaker logic. An engine start command from terminal 6 has a
higher priority than a start command from terminals 3/5. If terminal 6 is energized, termin-
als 3/5 are ignored. If the generator is in a mains parallel operation mode with "Parallel"
breaker logic and terminal 6 is energized, the GCB will be opened following a power reduc-
tion. The generator will continue to run without load and the GCB open.
Note: Load-dependent starting and stopping is not possible in sprinkler operation.
