Thanks for all the info, Gary.
I have the D60 which runs only on 24V DC, not the D60DUO that runs on 24VDC or 240VAC. The control panel is not the one pictured in your file on the owner's site. It has a switch that can be turned counter-clockwise to "Manual" or clockwise to "Auto". I contacted Dessalator who said that the blinking yellow light meant that the pressure is too low and that I should just crank up the pressure and see if it goes off. He said the relay/solenoid should not be clicking on and off with the blinking light because that would be shutting the motor on and off...but I had the unit turned on and while the light was blinking and the panel was clicking, the motor kept running steadily.
Sooo, it's going to take some more trouble shooting to figure out what's going on. I'll try cranking up the pressure when I get back on the boat, and if that doesn't solve the problem, I'll start looking further. I'll let you know what I find.
Currently Brunswick GA

Subject: [Amel] Re: Dessalator D60 amber light blinking
ADDENDUM: I just reviewed the manual that I wrote on this system, since Dessalator wasn't inclined to provide adequate documentation (see the Files section) and here are the details on the yellow LED:
"ii. Yellow LED (Labeled Bad Quality) Receives power from Logic Board Plug #3, Pin 4 and sinks to ground at the Logic Board Plug # 3, Pin 3. This LED illuminates when the ON/OFF Switch is ON, the low-pressure pump (elsewhere labeled as BP) is running and the Logic Board Timer (IC4) hasn't reached a pre-set time that is determined by the values of R1, R2, and C4 on the Logic Board. As configured on the Amel Super Maramu the illumination of the Yellow LED is in no way determined by salinity sensing and thus in no way reflects "Bad Quality"".
There is a pressure switch but it shuts down the system if too high of a pressure is sensed. There is not a pressure sensor for low pressure pump feed pressure.

board, it sounds like it is time to upgrade to the new board (About $750 last time I checked). On the original control panel, the amber lamp is an LED and so doesn't make any sound when blinking. The clicking you are hearing is undoubtedly one of the relays on the control board (located behind the control panel and accessed via the cockpit port lazarette, see photos section) that is opening and closing from some faulty circuit. Try recycling the system a couple of times and if it doesn't correct itself I would spring for the new board. The blinking and clicking has nothing to do with salinity or pressure, it is a faulty circuit (in my opinion). There are three relays on the control board. One controls the low pressure pump by controlling a large control relay in the control box, one controls the high pressure pump by similarly controlling a large relay in the control box, and one controls the bypass solenoid that sits on the top of the plumbing next to
the fresh water flow tube (see pictures in the Photos Section under my file on the Dessalator Water Maker). If the pumps are operating normally then the most likely relay clicking is the relay that controls the bypass solenoid. Gently tapping on the bypass solenoid or the relay might be a trouble shooting possibility. CAUTION, there are both 24 VDC and 220 VAC electricity in the control box, don't kill yourself if you aren't comfortable and knowledgable working on these types of circuits.
