In all I have 2 Hfo and 1 ME lo purifier,they all take water from the hydrophore line.the issue started with the ME LO purifier after it has gained the required rpm and I want to start the process,first it displays total de- sludging,then operating valve opened followed by the alarm 'FAIL TO SHOOT DE-SLUDGE MONITOR 'i have checked the water line n it has good pressure.
one thing I noticed is that before when I close the water supply and try starting the operation there is an alarm for BREAK OVER WATER but I tried that yesterday and there wasn't that alarm.
The number 1 Hfo purifier also started by giving alarm.for motor protection relay so I noticed the clutch disk were worn out which I changed and also cleaned the bowl ,changed all o-rings and boxed up.Aftwr starting the motor protection alarm has gone off only to be replaced with the same 'FAIL TO SHOOT DE-SLUDGE MONITOR ALARM' on the ME LO PURIFIER.
I seem to have checked any possible place I suspect yet to no avail...the ME LO PURIFIER has 3 solenoid valves whiles the Hfo has 6 ,2 for water and the rest still trying to find out.

Re: westfalia Purifier Problem
How old is this stuff? I haven't seen this PLC 100 for years. I would run the machine manually (without the automatic program) to test the separation and the ejection but it is unlikely that they are all defective. It must be something common to all three. "The water has good pressure" what is the pressure? Is there enough volume (flow)? Send the full model numbers of the LO and HFO separators and more photos, please.

Re: westfalia Purifier Problem
The vessel is 25 years so I presume same applies to the purifiers.The ME LO purifier is of the model OSA 20-02-066 whiles the HFO is OSB 35-0136-066.
The water pressure is about 3 to 10 bar,today I worked with the electrician all day trying to bypass sensors and also changing some yet to no avail.

Re: westfalia Purifier Problem
The first picture is the arrangement of the water line,2nd is the valves on the purifier 3rd the Hfo purifier and lastly the lube oil purifier...

Re: westfalia Purifier Problem
Why is there such a large range of pressure in the water supply, 3-10b? Does the hydrophore need recharging on the gas side (check the pressure at the schrader valve with the water pressure relieved)? There are four valves on a 0136 Unitrol: operating water open/close and operating water displacement on the bottom of the machine and sensing line return to inlet and water/oil discharge on the top and also the conductivity sensor (there may be other valves downstream of these). The best way to bypass sensors is to run the whole thing in manual i.e. you are the sequence, just follow the sequence in the manual and open and close solenoids at the right time to see if the machine works. As I said before it is unlikely that all three are defective
