Doser 2.2 Maxi

[Cali9dub]

If the 2.2 maxi stand alone utilizes it’s own port for level sensors once set as a slave to the P4 will that level sensor still work and be able to dictate how a pump will dose ??

Hello,

No, SA in EXT (slave) mode become a true EXT without level and temperature ports.

Well that sucks.

How many level sensors do you use with your p4? With two dividers - a P4 can use 4 sensors and you can always use an extension card to add 4 more sensors. These senors can be used for regulation of the slave pumps you have connected to the P4. I use a Maxi 2.2 slave for my top off. I have switch socket to react on the sensor in level 1 function.

My dose program 21 is a Maxi 2.2 slave head and react on switch 5. When you use a Maxi 2.2 as top off pump you do not even need a physical switch - you can use a "virtual" (a switch channel without a physical socket)

Yup. I get all that. Still sucks.

Agree - you paid for the hardware - would be nice if it wasn't disabled and worked on the PAB chain.

Technically, a Doser SA in EXT (slave) mode is presented on the PAB bus as a real Doser EXT (slave).
A new device would have to be virtually created, an EXT Doser with temperature and level ports.
This would require a lot of work on firmware and software.

Wait. So where do you set up a virtual switch channel or do you just pick one you’ll never use…like switch channel 50 or something ? I assume the virtual switch channel turns on when a float switch triggers it, subsequently telling the maxi 2.2 pump to turn on until the float switch is no longer in “error” mode. Is that correct ??

 

[Cali9dub]

Just set up the switch channel to be triggered by the float switch and have the switch channel trigger the maxi 2.2 ?

Yes

And the switch channel not need to be a physical switch - you can use S62 if you want

Also what tubing can you use with the 2.2. I can’t get regular 1/4” rodi line to go in the fittings to save my life! Lol.

 

[Cali9dub]

I found it. 6mm. Hope they don’t leak on the other end since 6mm is a tad smaller than 1/4”
