Engine Shutdown Detection Setup With Victronconnect - Victron energy Orion-Tr Smart Manual

5.2. Engine shutdown detection setup with VictronConnect

Open VictronConnect and press the Cog symbol

The following settings can be changed with VictronConnect:
The default values displayed are for the 12V input models. Those values are scaled depending on the input
voltage of the model. E.g. for 24V input models, the default values displayed on the manual should be
multiplied by 2.
Engine shutdown detection enabled: The engine shutdown detection is always enabled by default when the charger mode is
selected. When it is disabled by the user or when power supply mode is selected, the engine is considered to be running, so no
shutdown detection will take place.
Alternator type: The alternator type can be selected between "Smart Alternator", "Regular Alternator" and "User defined". When
"Smart Alternator" option is selected, the default values for the smart alternator are/will be applied to the engine shutdown
detection settings. The same will happen when "Regular Alternator" option is selected. When any of the settings differs from the
default values of the last two option, the "User defined" option will be selected. Default: "Smart Alternator".
Start voltage (V ): At this level charging starts immediately. Default: 14V.

lower start level is necessary for these systems. To ensure that the starter battery is recharged after starting the engine, charging
of the auxiliary battery is delayed during this condition. The energy used during starting must be replenished to ensure that the
starter battery remains properly charged. Default: 13.3V (Smart Alternator) and 13.8 (Regular Alternator).

draws 150A for 5sec to start the engine, about ~0.2Ah is drawn from the starter battery. If, during engine idling, the alternator can
only generate 20A, it takes 150A/20A x 5sec =37.5sec to recharge the starter battery. Default: 2 minutes.
Shutdown voltage (V ): This level corresponds with the engine being off. This keeps the starter battery fully charged and
shutdown
provides a hysteresis with respect to the start level. The hysteresis must be large enough to prevent V
would result in charge current reduction. Action will be taken after tshutdown runs out (1 minute); this allows charging during
temporary low voltage conditions. Default: 13.1V (Smart Alternator) and 13.5V (Regular Alternator).
Range for engine start/shutdown levels:
• 12|12; 12|24: 8 to 17V
• 24|12; 24|24: 16 to 35V
Setup input voltage lock-out: Input voltage lock-out is the minimum level at which charging is allowed, below this level charging
stops immediately. Default (in charger mode): lock-out: 12.5V / restart: 12.8V. Default (in power supply mode): lock-out: 10.5V /
restart: 12V.
When 'forced charging' is enabled, current will be drawn from the starter battery if the engine is not running.
Setting the lock-out level very low can result in a depleted starter battery.
To setup input voltage lock-out two criteria are important:
• Minimum alternator voltage: A smart alternator can operate at very low alternator voltage (<12.5V) e.g. when the vehicle
accelerates. This low voltage is allowed during tshutdown as shown in "engine shutdown detection sequence 3→4". If charging
must remain enabled during this period, the lock-out level must at least be set below the minimum alternator voltage.
