hi tasci,
what's the problem with your monitor?

Dear Zedrok

Sorry to late reply for your care.

The problem is monitor screen on the airway bargrapher.
Tha bargraph screen is not work. I have to change pressure sensor.
But.did not progress at all. could you help me? So this device programing language German. English is it possible?

hi tasci,
the pressure sensor got the order number 1831887. it comes fully calibrated and is easy to change.
you can check the bargraph like this:
-locate the connector X1
-connect pin 5 + 6 to 15V an pin 1, 2, 3, 4 to GND (or just let the connector connected to the board, so the right voltages will be supplied by the board)
-if you now connect pin 10 - 19 to GND, the correlating LED's (V15 - V24) have to lit.
if that works your bargraph is okay and maybe the driver is defect.

Dear Zedrok

The pressure sensor changed. there is intrestings issue on display. the flow units works. But cant check the bargraph for Paw graphic. I havent see any description PCB layer top. There are three driver on bord.
which is one damage I m not sure. Please if you have schematics or diagrams, Could you sent them.
Regards

Hi Tasci,
check your mail for the schematics.
sorry for that late reply.
regards zedrok

Hi Zedrok

Thank you for the schematics.
scheme has been very helpful to us.
We are solving electronic fault on pcb layer. we are taking all analog and digital data on bord with CPU datbus line.
But we dont get any digit on bar graph. Do you find service aplication for calibration or any information.
Regards.

Dear Tasci,

you checked it in service mode in the PM8030?
