The pump is not running via the manual test at all when the control signal for the contactor to bring the pump on is definitely live. Maybe someone know how the controls manages to calculate suction superheat - there is a suction pressure transducer but no suction temperature sensor?! Is EXV position not guided, to any extent, by the SH here? The 30Gx calculates discharge superheat Electronic Expansion Device Module — The electronic expansion device module has 4 inputs and 2 outputs. ![]() ![]() It receives signals from the PSIO- 1 module and operates the electronic expansion devices. The electronic expansion device module also sends the PSIO- 1 module the status of its 4 input channels. Thanks James. Have searched the whole thing thoroughly today ( the chiller) - no suction temp sensor on it. On its main board there are OAT, water-in, water-out temp sensors, on the compressor protection board - discharge temp, and motor temp. How it calculates the SH (if does it at all) - seems to remain a mistery to me. By Gibbo The readings you have are they from the carrier display or have you measured this.The readings were from the display. While the good system drove the water T down from 13 C to 10 C (SP), DSH was indeed about the value you have mentioned: 6 C to 11 C. But on the bad system (which had tripped on 'low suction T' finally), at the point when water out T was 13 C DSH here was even not positive but mostly negative! To raise the DSH the controls 1. Started frantically the fans - driving SCT down (because DSH = DT - SCT). ![]() Closing EXV By that the evaporation P went abruptly down. The controls sensed too low suction T (suction T is directly derived from the evaporation P ), the system tripped on the low suction T. I am beginning to think now, there are uncondesables in the latter system, Hi P transducer senses higher T than would be the T correspponding to uncontaminated 134a, and so is trying - wrongly - to lower SCT. Subcooling was very good: 15 -20 K. Sorry, Gibbo, all I have is this: 5.13 - Compressor.compressor. 5.14 - EXV control The electronic expansion valves (EXVs) control charging and the refrigerant flow in the evaporator, maintaining the optimum evaporator throttle and a correct discharge superheat. Opening the valve permits reduction of the throttle, and thus improves the heat exchange in the evaporator. This opening can be limited to maintain the condenser subcooling and correct superheat, avoiding liquid slugging at the compressors and ensuring operating stability. 5.15 - Motor cooling valve control The temperature.pressure. Very general information. Pro dialog plus. And through this interface it is only possible to open or close EXV - no possibility of choosing a% of opening in test mode. The system should be short of gas. At start, after reset (system have stayed several hours out of work), with the compressor yet cold, the system kept EXV almost closed, trying to lower DSH. After another low suction T alarm and the immediate reset of it, copm has gotten heated up, discharge T was now increased, system was not more busy keeping DSH down, EXV was now alloweed to be opened - it did so up to 100%! Evaporation T (P) did not increased much by that, however, motor T rose up to more than 90 C. I wisely turned it off. The system is surely short of gas. • Cookie Consent We use cookies to improve your website experience. To learn about our use of cookies and how you can manage your cookie settings, please see our.

I have a 54 problem on the circuit A of the chiller with its circuit B working - I am assuming this is genuinely an oil problem as the circuit starts up okay and then cuts out after a while On our other chiller we have a 75 / 75 issue on both circuits. Carrier Chiller 30gx Service ManualsI have checked the flow switch (which is fine) and tried to run the evaporator pump manually in test mode and it does not start. Anyone have any ideas? We had a few of these issues before and they generally went away and worked fine but now has been over 2 months and not once will they reset and run - it times out after the 2 min delay. I read somewhere that it is being held off by a carrier service reset is this correct as the only thing that doesn't run in test is the evaporator pump Any help appreciated. The oil level switch is fitted at the bottom right of the oil seperator the oil level switch is a small brass cyclinder shape with plug on top.

Chiller Carrier 30 Gx Manually InstallRegarding the water pump are you saying the output to pump contactor is ok. I am assuming this is a Carrier French made 30GX. Manuals wiring diagrams can be found at 'eto.carrier.com/lit. Windows 2008 r2 activation key. asp' however there are 3 variations at the above site. Chiller Carrier 30 Gx Manually MeaningPhase 1 has the old psio style control. Phase 2 has the black pro dialog display. Phase 3 has the cream coloured pro dialog plus display. Both phase 1 & 2 are now obsolete so parts can be an issue requiring various modifcations.
