Help with new crash sensor Truma regulator

[Kayak Kid]

Just fitted this new Truma CS Crash Sensor regulator and connecting hose with rupture protection button.
Followed all steps for startup as indicated but getting no gas to cooker as my test. Each time I have repeated the start up process, I get a tiny hiss of release of gas at cooker then no further gas!
Gas bottle full and all usual gas taps open.

Any ideas please?

Are you pressing both buttons ?

Do you have to press the yellow button to rest the sensor the press and hold the other 2 together for 3 secs

MonoControl CS (black)

If the crash sensor has been triggered, it can be easily reset. Simply press the yellow reset button on the MonoControl CS (black) gas pressure regulator and the gas pressure regulator is ready to use again.

MonoControl CS (silver colored)

The MonoControl CS gas pressure regulator is ready for operation again when you firmly press the green reset button (with a sharp object, such as a ballpoint pen) for about five seconds.

Yes, but not at the same time.

The unit is the silver one and instructions shown in the photo above say press each of the buttons for around 5 secs. Doesn’t say press both at same time so haven’t tried that. Have repeated process outlined at least 12 times with same result.

Disconnect after each bit a see if you do, or do not have gas pressure.

And make sure your cylinder valves are open and you have gas in them.

The button on the regulator you have to hold it really hard for 5 - 10 seconds, try that.

I am away from the Motorhome at the moment - but will go back down shortly and try holding buttons harder and longer, and also try it holding both buttons ( regulator and hose) at same time.

The hose one you can often hear a click, you don't need to hold both at the same time.

Mine is the Duo control CS and you have to press both buttons together for at least 3 seconds

 

[Kayak Kid]

Didn’t think it would require both held together but was willing to give it a try. Going back to retry in next 15 mins but don’t recall hearing a click from the hose button. Maybe missed it though on first try.

Time to change it then.

Well - spot on LennyHB! The problem was that the regulator reset button was not being pushed in far enough! The ‘housing’ around the button was not allowing my finger to push far enough in - and as I hadn’t done it before I didn’t know it could go in further. I pushed it in with a screwdriver and immediately felt it go in further. Job done and thank you.

Hi Basildog,

Thanks for your offer of help and advice. As you will see the problem is solved.

When I bought the unit last year I knew it was a 2018. It was unused, in sealed Truma pack with instructions etc. What is the issue with its year of manufacture if unused?

Thanks to everyone else for their input!

It’s fine if you knew that you were buying an old regulator , retailers aren’t supposed to sell a regulator as new after 3 years .
Just bare in mind that @ 10 years old a regulator is technically due for replacement.
10 years is the recommended lifespan of both regulators and rubber pigtails.

Thanks Basildog - that’s helpful. It was clearly indicated by the retailer that it was made in 2018 - so I was made aware of this. Useful to know the recommended lifespan of the units. Whilst I did know that the pigtails had a recommended replacement date (2027 indicated on mine) I was not aware of the recommendation for the regulator.

I suspect there must be quite a few regulators on motorhomes and caravans etc still in use past that recommended replacement date.
