Hello guys . Meanwhile, damage and downtime of the equipment continues to rise. A phase loss will sometimes call out a phase reversal alarm. Power Supply Module NOTICE… if this unit is replacing a purge unit on a YORK chiller with either a “Micro-Panel” or “Optiview” control panel, you MUST wire the chiller “Run Signal” according to the Electrical Schematic Figure 5A on page 30. As soon as the phase monitor on the chiller detects a phase loss, it shuts down the chiller AND condensers.. Unequaled Reliability Starter types include Across the Line (RTAC), Y-Delta and Solid State (RTHD). Hi guys, A lil' bit of introduction: I am a fresh-grad project engineer in a small-ish HVAC company and recently, a client of the company called us to troubleshoot a Trane chiller as it is not providing sufficiently cold chilled water. - Phase loss/Power loss. What is Phase Loss? A refrigerant loss detector and alarm, the detector device suitable for installation in the piping of a refrigeration system which utilizes a liquid/vapor phase change substance as the refrigerant. Trane Chillers Air-Cooled Chillers. The chiller controls should prevent the machine from running in such case. If I recall correctly, some early software did have some "unknown diagnostics". These relays notify of fault conditions and provide control contacts to turn off motors or other equipment before damage occurs. Gain access to our free AOP (Ask a Professional) Section to get real answers for your questions. Communication card for LON protocol Phase protection device Disable the unit from running in case of wrong electrical phase connection.

Maybe as chillrdude stated the chargeman is cycling power to reset it when it trips. When one phase of a three-phase system is lost, a phase loss occurs. - Welded contactors. Voltages and currents in a three-phase system do not typically just drop to zero when a phase is lost. When one phase of a three-phase system is lost, a phase loss occurs. Typically, a phase loss is caused by a blown fuse, thermal overload, broken wire, worn contact or mechanical failure. Under phase loss conditions motors, pumps, blowers, and other equipment draw excessive current on the remaining two phases which quickly overheats the motor windings. Page 62 Installation – Electrical Table 21 - Alarm and Status Relay Output Confi guration Table Diagnostics Alarm - Latching This output is true whenever there is any active diagnostic that requires a manual reset to clear, that affects either the Chiller, the Circuit, or any of the Compressors on a circuit. I have seen some diagnostics, for whatever reason, that you couldn't clear with the display. I haven't pulled the manual because I wasn't sure what chiller you had but most modern chillers use a flow switch for proof of flow and the chiller's LWT and RWT temperature sensors for a FLOW TOO LOW alarm. Further, the relay provides clear indication of the fault present allowing for rapid troubleshooting and reduced downtime. Upon detection of refrigerant vapor accumulating in the loss detector, thereby displacing refrigerant liquid therefrom, the orientation of a float element containing a mercury switch is affected.
