Configuring battery monitoring in the SharpOS 13.7 Sharp Portal - SharpZ3 | SharpOS 13.7

By default, power to the SharpZ3 base unit and connected devices continues to be supplied for 60 seconds after the vehicle engine is turned off. You can configure how power is managed when the system shuts down.

1. Log on to the Sharp Portal.
2. Click Configuration > General settings > Power options.
3. Click Show Advanced.
4. Configure Battery Monitoring settings.

   Turn on voltage

   Input voltage threshold below which the unit does not turn on.

   Ignition cut-off delay

   Grace period between ignition cut-off and base unit power-down.

   Undervoltage

   Input undervoltage threshold that causes a unit shut-off if maintained for a certain time.

   NOTE: The voltages in the following table are measured at the base unit power connector. Note that there is an approximate 0.5 - 0.7 V drop between the battery and the base unit power connector.

   Parameter	Minimum	Maximum	Default
   Turn on voltage	9.5 V	25.5 V	11.7 V
   Ignition cut-off delay	10 seconds	30 minutes	60 seconds
   Undervoltage	9 V	25.5 V	10.3 V

   NOTE:

   • The Turn on voltage and Undervoltage parameters have a precision of 0.1 V. For example, a voltage of 20.789456 V is rounded to 20.7 V.
   • The Ignition cut-off delay parameter is rounded down to the nearest 10. For example, a cut-off time of 48 seconds is rounded to 40 seconds.
