5.4.16 Additional running engine indications
It is helpful to have information other than speed (RPM), whether the engine is rotating or not, especially if RPM
is measured from the generator frequency instead of magnetic pickup. The generator frequency measurement
can be unreliable at very low speeds and/or may have a delayed reaction to sudden and big changes (i.e. in the
moment that the engine has just started…).
The following conditions are evaluated as additional running engine indication:
Voltage on the D+ input is higher than 80% of battery voltage. Connect this input to the D+ (L) terminal of the
charging alternator and enable the D+ function by the setpoint D+ Function. If D+ terminal is not available,
leave the input unconnected and disable the function.
The pickup is not used and frequency is not detected on the pickup input. Connect the pickup input to the W
terminal of the charging alternator if you do not use pickup and the W terminal is available. If not, leave the
input unconnected.

setpoint. The oil pressure is evaluated from the analog input or
from the ECU if an ECU is configured.
At least one phase of generator voltage is >25% of nominal voltage.
These signals are used during start for powering down the starter motor even if still no RPM is measured and
also during stop in order to evaluate if the engine is really stopped.
5.4.17 Voltage phase sequence detection
Controller detects phase sequence voltage terminals. This protection is important after controller installation to
avoid wrong voltage phase connection. There is fix defined phase sequence in controller L1, L2, L3. When the
phases are connected in different order (e.g. L1,L3,L2 or L2,L1,L3) following alarms are detected:

5.4.18 Gen-set operation states
Engine state machine
Init
Autotest during controller power on.
Not ready
Gen-set is not ready to start.
Example:
When shutdown alarm is active or unit is in OFF mode.
Prestart
Prestart sequence in process,
output is closed.
Example:
Usually used for preheating or processes executed prior gen-set start.
Cranking
Engine is cranking,
output is closed
Pause
Pause between start attempts.
Starting
Starting speed is reached and the Idle timer is running.
Running
Gen-set is running at nominal speed.
Loaded
Gen-set is running at nominal speed and
is closed.
Stop
Stop.
Example:
Automatic or manual stop command was issued, engine is stopping.
Shutdown
Shut-down alarm activated.
