I'm a Commercial heating engineer looking to get more knowledge of BMS controls, I didn't even know channels like this exsist, I've been searching for training academy for bms for a long time. Over the moon with this
I would push the pump contactor in with a screwdriver and see if it runs and if there is power on the output of the pump relay. If it works then I would be checking the A1 and A2 contact for voltage. If no power go to the relay that operates the coil
Spent over40 years doing this, it always amazes me how many engineers don’t fault find sequentially and logically. So often you go to a new customer and ask where the drawings are, and just get a blank look and the last guy just fiddled with this bit 🤷♂️. Or the drawings are all screwed up and trampled on in the bottom of the panel. Got to think logically, starting at the bit that isn’t working and work back. Without drawings is the challenge and makes you look Like you don’t have a clue what you are about
thanks for sharing 👍, could you provide a standard/basic procedure list of all the steps to follow for panel fault finding that you can use as starting point ? thanks in advance 👌
Thank you for the Great Video.
Just found you today, thank you for all your videos mate, exactly the content I was seeking.

This is standard for anyone with basic real world experience.
what if the contactor is closed because the low pressure alarm has been triggered ?
Before you start putting links in you'd look to see if the relays are engaging, basic function test as you would do before it left the workshop
