Timed output after key off

PMU
1

Has anyone been able to have a timed output keep running after the ignition it turned off? It’s for something different, but let’s say I wanted a cooling fan to run for 1 minute after key off. Does the entire pmu shutdown when key is turned off or can I have an output programmed to a timer continue running until timer is done? I have timer function working for other outputs but haven’t figured out the key off part.

Hi,

there is a “Delayed turn off” panel in PMU, where you can configure it. You can add a panel using F9 key.

You can also make some logic to wait for the delay or not:

Check out the 16.7 chapter in the manual.

Thanks! That keeps the entire pmu on and I’d like to only keep one output running. I’m trying to keep a bms powered up for a certain amount of time after the car is shut down. But only want the bms to be powered.

There is no option like that.
The whole device is either switched on or off.

But from your description, I don’t see why the available feature is not enough.
When you switch the ignition off, you can keep the PMU on for a specified duration and have only the BMS output active. After the delay, the PMU is switched off completely, along with the BMS.
