Insuffi cient oil pressure time for the compressor is stored and Copeland Discus compressors utilize the Sentronic oil protection system which monitors oil pressure from the oil pump to determine if there is satisfactory oil flow going to the bearings. refrigerant dilution or low oil level), removal of the oil pickup screen Copeland Discus Compressor with Demand Cooling System BULLETIN NO: AE4-1287 R10 Safety Important Safety Information 2 Responsibilities, Qualifications and Training 2 Terminal Venting and Other Pressurized System Hazards 2 Flammable Refrigerant Hazards 3 Electrical Hazards 3 Hot Surface and Fire Hazards 3 Lifting Hazards 3 POE Oil Hazards 3 D6. The oil level can go down to the top of the oil pick up screen before there will be insufficient oil available to maintain oil pressure. Discharge Temperature Protection 8 . 9 1. 3 Fault History 9 Like previous versions of Intelligent Store Discus, the CoreSense Diagnostics module will store the fault history record. Once the total time accumulated for bad oil pressure (a reading less than 7-9 PSID) exceeds 120 seconds, the module will shut the compressor off and a “low oil pressure lockout” will be reported. Unlock the power inside. 1 Compressor Protection 9 Copeland Discus compressors deliver best in class performance Copeland Discus compressors have been the unquestioned leader in commercial refrigeration for over 30 years. Multiple Compressor Applications 8 . copeland compressor oil pressure problems - HVAC-Talk The oil level of the R-410A Discus compressor should be adjusted to the mid-point of the compressor sightglass during normal operation. Protection against low oil pressure, excessive discharge temperature, high discharge pressure and low suction pressure is standard on every Copeland Discus compressor with CoreSense Diagnostics. 63 Bar, the oil pressure K & L compressor oil circulation The oil returning from the evaporator reaches the crankcase via an oil separator chamber behind the suction shut-off valve through a small connecting bore. E2. Normal oil pressure is between 1. Refrigerant Charge 7 . 1 Common information about Copeland™ semi-hermetic compressors This manual covers all Copeland semi-hermetic compressors. Oil Charges 7 . Copeland Discus integrated with CoreSense™ Protection offers the ultimate safeguard against insufficient oil pressure, high motor temperature and is capable of high discharge temperature protection . 2 bar higher than crankcase pressure. . Overview of the Copeland Discus Compressor with CoreSense Diagnostics v2. Accumulators 8 Nov 14, 2007 · What should the oil differential pressure be on a copeland discus compressor? I just replaced one today (grounded) and the new compressor will unload when still having a call for y2. The compressor will turn back on once the Protection against low oil pressure, excessive discharge temperature, high discharge pressure, and low suction pressure is standard on every Copeland Discus compressor with CoreSense Diagnostics. This optimizes the technician’s time, saves money and ultimately frees operators to focus on other priorities. Insufficient oil pressure time for the compressor is stored and accumulated in the module memory. Combining world class efficiency and reliability, Discus is the compressor of choice to meet your refrigeration needs. Motor Protection 7 . Typical New Copeland 3-Wire Oil Pressure Safety Control Wiring . 2D-6D Copeland Discus compressor Provides oil pressure, motor and discharge temperature protection Stores fault history information Communication enables remote reset Provides protection features found in Copeland Discus with CoreSense Protection Integrates traditional high/low pressure cut-outs with compressor Enhanced diagnostics and AGL_HA_ST_Discus_A2L_A1_EN_Rev00 1 About these guidelines The purpose of these guidelines is to provide guidance in the application of Copeland™ semi- Another symptom of a plugged oil pickup screen is a return to higher oil pressure after the compressor starts again, followed by lowering oil pressure as the run time increases. Crankcase Heater 8 . Oil Management The R-410A Discus compressors are each equipped with electronic oil pressure protection using CoreSense Protection technology. The module features a 2-line liquid crystal display on the front of the compressor that indicates the operational status of the compressor with a - Module Will Shut Down The Compressor When Oil Pressure Falls Below 7 -9 PSID For 2 Minutes Features - Precise Electronic Control Module To Monitor Oil Pump Differential Pressure Switch - Oil Trip Triggered By 2 Minutes Of No Positive Oil Pressure - Provides Alarm Indication Via LED Status Display - Communications - External Alarms 1. 1 Diagnostics 8 1. g.
