Terminal 6
ATTENTION
The various functions of terminal 6 are enabled at different signal levels!
Parameter 239
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 (setting a LOW signal), the sprinkler operation (critical mode)
is enabled in accordance with the functional description. The sprinkler operation is termi-
nated by energizing terminal 6 (application of a HIGH signal). For a description of the
sprinkler operation function read "
Sprinkler (Critical) Operation" on page 112).
Note: No load-dependent starting and stopping is possible in sprinkler operation.
Attention: This is a negative logic function!
• Engine enabled
Terminal 6 has the same function as the STOP push-button: De-energizing terminal 6 (appli-
cation of a LOW signal) prevents the engine from starting and stops the engine if it is al-
ready running. Applying a HIGH signal enables the starting of the engine
Attention: By the use of this function, the emergency power operation may be aborted or
prevented. The emergency power operation is not possible without enabling this function!
The enable engine function only functions in the AUTOMATIC operation mode.
• Engine blocked
By energizing terminal 6 (application of a HIGH signal) a start of the engine can be pre-
vented. If the engine is running due to an active emergency power operation, energizing this
discrete input will stop it. The engine block function is only possible 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 energizing terminal 6 (change from a LOW to a
HIGH signal) in the STOP and AUTOMATIC operation modes. In order to achieve addi-
tional acknowledgements, terminal 6 must first be de-energized and then energized again. If
terminal 6 is continuously energized (HIGH signal), there is no effect on the acknowledge-
ment and suppression of alarm messages.
• STOP mode
By energizing terminal 6 (application of a HIGH signal) the STOP mode is enabled. If the
signal is removed (de-energized), the operation mode will revert back to the mode that was
active prior to terminal 6 being energized.
• Start without CB
If the terminal 6 is energized, the engine starts. No synchronization is performed and the
GCB is not closed (no switching to dead busbar). The GCB is closed only if an emergency
power operation is enabled. After the return of the mains, the load is transferred to the mains
according to the configured breaker logic. An engine start command from terminal 6 is a
higher priority than a start command from terminals 3/5. If terminal 6 is selected, 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 is opened following a power reduction.
The generator will continue to operate without load and an open GCB.
Note: No load-dependent starting and stopping is possible in sprinkler operation.
