AC input connection delay when using a generator

Hi.

Is there any good way to delay the connetion of a generator to a Multiplus, so that it can warm up for 5 minutes before the AC input connects and start loading the generator?

@Kjellare Yes, you could use an assistant for that. You can use the AC input Current Control assistant and a temperature sensor connected to the generator.

In a situation where it isn't realistic to use a temp sensor on the genset - and ags is not use - is there a simple way to change the delay time? Currently, my MP-II automatically delays 15 seconds from the time it senses voltage at the input to the time it begins to use that generator power. It would be great to just be able to adjust that 15 seconds up to a longer period.

@CGES.Mike

You could try Assistants without the temp sensor. I've only tested this the once, but confident it'll work when I need it..

This is a 60 sec delay before power acceptance. The 300 sec just arbitrary to bring it back to Ignored after it's beyond my local rejection issues.

If you have a CerboGX in your system you can manage generator start/stop via its relay with the functionality you require.
