Hi everyone,
I have an issue on the down arrow button for the venous module. pressing the down arrow during treatment will increase the level instead of decreasing. may I know how I can simulate it without patient on and specially testing it after parts replace.
thank you.

A quick way to test is by putting your thumb over the port and pressing the up or down button. Pressing up should cause a vacuum, sucking your thumb to the port. Down should do just the opposite. This is the first I've heard of it increasing while pressing down, I've seen chamber level decreasing while pressing the up arrow before, but I doubt the fix is the same. Did it just randomly come up, or had anyone done previous work to the module?

Can you hear the pump in the level detect module run when you press the down arrow?

If you take your level detector out and look at the clear tubing that goes to the pressure port. It connects to a black box on the circuit board. This black box has 2 ports. One port is the correct one and the other does as your describing, which is just the opposite of normal function.
The spares i looked at your clear tube should be connected to the bottom port on the black box.
To simulate it just connect the port to your pressure meter(90xl for me) and push one of the buttons.

I had that issue last week. You can also string the machine and test it with saline in the lines only and the pressure transducers attached. Mine worked fine. My thoughts were that it was back pressure from the pt access.
