Figure 31. Connection of normally closed (NC+) sensors
Note:
It is recommended to connect one of the universal input (usually
UIN1
) to the vehicle
ignition line
and
make the appropriate setting in the configuration. However, such connection is not mandatory.
In addition to the source of notifications about turning on and turning off events, the input is used in coordinate
processing algorithms (for example, when they are averaged at parking lots), energy saving, when calculating engine
hours and in some other device algorithms.
Any input which configured for operation with a discrete sensor can be used as an ignition.
