The discrete outputs can be "programmable" or "fixed" depending on the application
mode (parameter
╚═▷ 3444 ).
For information on the function of the discrete outputs depending on the configured
application mode refer to
╚═▷ “4.4.2.3 Discrete Outputs (LogicsManager)” .
CAUTION!
Uncontrolled operation due to faulty configuration
The discrete output "Ready for operation" must be wired in series with an emergency
stop function.
This means that it must be ensured that the generator circuit breaker is opened and the
engine is stopped if this discrete output is de-energized.
If the availability of the plant is important, this fault must be signaled independently from
the unit.
CAUTION!
Uncontrolled operation due to unknown configuration
The circuit breaker commands must be checked before every commissioning because the
relays can be used for different applications and can be assigned to various functions.
• Make sure that all relay outputs are configured correctly. •
Output Type/Preset Description
Relay output [R
01] Programmable
Fixed to "Ready for operation"
CAUTION! Only relay [R 01] has an
inverse logic. The relay opens (all
other relays close), if the logical
output of the LogicsManager becomes
TRUE.
This discrete output is used to ensure that the internal
functions of the controller are operating properly.
It is possible to configure additional events, which cause
the contacts of this discrete output to open, using the
LogicsManager.
Relay output [R
02] Programmable
Preconfigured to "Centralized alarm
(horn)"
When a centralized alarm is issued, this discrete output is
enabled.
A horn or a buzzer maybe activated via this discrete output.
Pressing the button with the "✔" symbol will acknowledge
the centralized alarm and disable this discrete output.
The discrete output will re-enable if a new fault condition
resulting in a centralized alarm occurs. The centralized
alarm is initiated by class B alarms or higher.
Relay output [R
03] Programmable
Preconfigured to "Starter"
The generator starting circuit is engaged when this discrete
output is enabled.
This discrete output will enable depending on the start
sequence (refer to the start sequence description in
╚═▷
“4.4.1.1 Configure Engine (general)” ) to energize the
starter for the configured starter time (parameter ╚═▷
3306 ).
