hi Guys, in our cardiac ICU, we have 7 suction machines, and we have the same problem. When the machine is turned on, the push button comes blue, it makes a sound like there is no power, when I check the outlet for 12v for the motor, it is not present. if somebody has experience with this kind of problem, please, if you can help me
THANK YOU
Equipment: medap vent sp 26
hi, first are you a biomed or a user?
when you say you check the outlet, do you have the unit apart, are you checking the wall outlet or are you checking where the power cord plugs into the device?
if you are checking the motor for 12v, perhaps your power supply is bad and you're not getting the 12v, or you're not plugged into a working wall outlet and therefore not getting the 120v.
if your power supply is putting out 12v but it's not showing at your motor, then perhaps you have a bad power switch or cabling. If there is a control board in between, perhaps it is not sending a signal to the pump
FIRST I AM A BIOMED AND THANK YOU FOR YOUR QUICK RESPONSE, when I say I cheak the outlet I am referring the outlet from the power supply PCB and yes it is 12vdc also in the control board inlet there is 12vdc in 2 SHOTTKY DIODES OUT PUT I FOND 12vdc I am not getting 12dc in the motor connector it singleL LAYER PCB THAT I WONT THE SERVICE MANUAL IF IT NOT POSIBLE ATLEAST THE CIRCUIT DIAGRAM
HI MICHEL STILL NOT,I COULD NOT FIND THE SERVICE MANUAL OR CIRCUIT DIAGRAM THANK YOU
KINDLY BEFEKADU
I believe maquet owns that thing, I can't find anything more than a user manual unfortunately.
If you're getting 12vdc to the motor. Then your motor is bad, if not, the pcb. Not really going to do board level repairs so, save yourself time, play with the power supply later. Let us know what you find.
HI CHRIS THANK YOU I AM NOT GETTING 12dc in the motor connector but I get 12dv somewhere else like in the Schottky diodes and other points the problem now is how to give 12dc to the motor connector without causing a short circuit in the PCB
ok so you've got a bad pcb. We don't do component level for a reason, liability. For fun, sure play with every component till you find it, for insurance reasons, just pull the entire board and replace it.
