I talked with manufacturer the head pressure control is set to 235 max for 410a water cooled my head pressures were over 300 normal 410 pressures, they had three belimo valves 2 stayed open one which...

384941384951384961384981[ATTACH=CONFIG]problem solved went back topday to pm all units there was 3 water accuator valves on the in/outlet 2 were open one was closed, the closed one was labbled head...

it says l1 terminal is control voltage so if it is wired through y like you say how is this problem fixed where is your y connected to if not l1

that's my point these units weren't put back properly the pink 410a label on top of both compressors in one unit means they are regular scrolls according to what your saying while in the other unit...

makes sense because one unit the compressor was unloading the other wasnt

im pretty sure both these units were broken down to get into space if 2 regular scrolls went in one unit and 2 digital in the other would this be causing the problem im having? becaue when I was...

384551384561when I go back this week ill take some pictures and post them, there is a 50 page book in the controls box showing how everything is wired and works, didn't have time to really go through...

well if both compressors have their own low/head pressure switches its not a single circuit wright? so that would eliminate the low pressure point your making, but I do believe its a installation...

well the most common thing between both units is the water supply they share the water temp going in I believe was 70 pressure going in was 60

I don't know was only there for a hour on Friday unit is still under warrenty so I don't know if I will be fixing it, yes both compressors shut off at the exact same time weird, they both don't turn...

there's a pressure transducer on the discharge line, when the 2nd compressor comes on they both run a minute or so then both shut off and the 3 red blinks show on controller then they come on again a...

so its normal operation for these digital scrolls to constantly short cycle with poor modulation what a bad design

yeah this is the controller both compressors are the same and I have one of these controllers in each unit with 2 compressors in each unit never worked with this type of controller doing some weird...

well i only have low and high pressure controls high is manual reset so cant be that low is auto maybe faulty low pressure water is good but 2 separate units doing the same thing weird

ok so my problem is I have a call for compressor but its getting locked out due to no amperage being detected

what im thinking is that when the 2nd stage compressor kicks in there is a power drop goes below 208 and is sensed through this device shutting down the compressors when I go back next week im going...

it did start that's not the problem 1st stage runs second stage comes on 1 minute or so later both compressors go off then come on again minutes later same thing olver and over red light blinks 3...

like I said there are 2 units same make model brand new doing the same thing just odd I checked everything already covering the basics

I need to know what causes this type of code

Flash Code 3 - Compressor Protector Trip
The demand signal from the system controller is
greater than 1.44VDC and there is no compressor

I don't have a pick of the diagnosis box only the one mounted to the compressor its black has a green status light a red light that says alarm and a yellow light that says unloaded yessss that's it...

know a regular scroll compressor the black box mounted in the unit tells me by the blinking lights compressor overload that's it

not that I know of ill take a better look when I go back next week but I was leaning towards that gotta be the voltage maybe running a little low I think I was getting 199 volts on all three phases...

units are in a closed loop system connected to a dry cooler I have 2 leiberts for a server room running off the same dry cooler and their doing fine,you talking about replacing the motor protector or...
