Engine Shutdown Detection Override - Victron energy Orion-Tr Smart Manual

4.5. Engine shutdown detection override

In charger mode the "engine shutdown detection sequence" determines if conditions are met to enable charging, see chapter 5.
The "engine shutdown detection override" forces the charger to allow charging independently of the engine shutdown detection.
Engine shutdown detection override is activated by applying >7V to the remote L-pin. This allows external control (e.g. ignition
switch, CAN bus engine on detector) to enable charging.
This function does not override the remote on-off function. Remote connection a), b) or d), as shown in Figure
3 must be configured in combination with engine shutdown detection override. See examples in figure 4.
Enable charging with an ignition switch and remote on-off
option a)
Enable charging with an ignition switch and remote on-off
option d)
Figure 4: Engine shutdown detection override connection diagram
If the ignition switch in figure 4 is switched off, the charger will return to "engine shutdown detection" mode, it
will not turn off the charger.
To force enable/disable charging (i.e turn the ORION on/off) without the "engine shutdown detection" a remote option as given in
chapter 4.4 must be wired, and the engine shutdown detection must be switched off in VictronConnect, see figure 5.
