Series R Air-Cooled Helical Rotary Liquid Chillers – RTAC Plus 140 – 350 Ton […] A three-phase monitor relay protects against damage caused by phase loss as well as other three-phase fault conditions. As soon as the phase monitor on the chiller detects a phase loss, it shuts down the chiller AND condensers.. — Do NOT store or use gasoline or other flammable vapors and liquids or combustible materials in the vicinity of this or any other appliance. - Phase loss/Power loss. I have a problem with above Trane chiller and i need some wiring documentation . Other than that if power is not being cycled would recommend the software be upgraded. View and Download Trane RTHC installation operation & maintenance online. Unequaled Reliability Anything below this for 2 minutes will trigger alarm and shut chiller off. Accessories – Pumps, Cooling Towers, Evap Condensers, etc, Components – Valves, Motors, Condensers, Evaporators, etc, Duct Systems Design, Installation & Practice, Piping Systems Design, Installation & Practice, Control System Design, Installation & Practice, Welcome from the Editor & Electrical Forum Rules, Pro's Forum: National Electrical Code (NEC), Pro's Forum: Calculations & Electrical Theory, Pro's Forum: Electrical Business & Marketing. Split System. The starter module provides protection of the compressor in the form of running overload, phase reversal, phase loss, phase imbalance, and momentary power loss. I have seen some diagnostics, for whatever reason, that you couldn't clear with the display. The services of a qualified technician should be employed through the medium of a maintenance contract with a reputable service company. If a fault occurs, one of over 90 indi-vidual diagnostic and operating codes will displayed directly on the control module. 2, 3, 4 & 5 Tons The heat from return chilled water and from the pump heat loss will try to maintain the ... • Free cooling is active : Chiller water flow is present & there is a call for cooling. Check the resistance of current transformer (CT) … They do not contain full service procedures necessary for the continued successful operation of this equipment. The event action table contains both a set of instructions for alarm routing and a stretchy list of referencer objects (the potential receivers). Post photos, respond to polls and access other special features. running, and stopping the chiller. Trane CGAM chillers have three distinct leaving water categories: † standard, with a leaving solution range of 42 to 65°F (5.5 to 18°C) † low temperature process cooling, with leaving solution range of 10 to 65°F (-12 to 18°C) 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. So those will be ok, no more blown fuses. Components – Coils, Heaters, Motors, etc. This is also called 'single phasing'. - Welded contactors. It can control the operation of the complete installation: chillers, pumps, cooling towers, isolating valves, air handlers and terminal units.Trane can undertake full responsibility for an optimized automation and energy management A phase loss will sometimes call out a phase reversal alarm. IMPORTANT: C wire or 24VAC power is required for the LS-90 to operate. The extensive Trane chiller product line was developed based on decades of knowledge and industry leadership, and includes centrifugal, helical-rotary and scroll compressor chillers, ranging in capacities from 20 to 4,000+ tons.
