Page 4: General Recommendations
General Recommendations Technical Data As you review this manual, keep in mind that: • All field-installed wiring must conform to European guidelines and any applicable local codes. Be sure to satisfy proper equipment grounding requirements per European guidelines. • Compressor motor and unit electrical data (including motor kW, voltage utilization range, rated load amps) is listed on the chiller nameplate. - Page 5 General Recommendations WARNING! Discharge Time: Frequency converters contain DC-link capacitors that can remain charged even when the frequency converter is not powered. To avoid electrical hazards, disconnect AC mains, any permanent magnet type motors, and any remote DC Sound power levels link power supplies, including battery backups, UPS and DC-link connections to other frequency converters.

Installer-Supplied Components / Interconnecting Wiring Technical Data Installer-Supplied Components Customer wiring interface connections are shown in the electrical schematics and connection diagrams that are shipped with the unit. The installer must provide the following components if not ordered with the unit: •... - Page 7 Installer-Supplied Components / Interconnecting Wiring If evaporator water flow is not established in 20 minutes (for normal transition), the UC800 generates a non-latching diagnostic. If flow returns (e.g. someone else is controlling the pump), the diagnostic is cleared and normal control resumed.

Programmable Relays Technical Data A programmable relay concept provides for enunciation of certain events or states of the chiller, selected from a list of likely needs, while only using four physical output relays, as shown in the field wiring diagram. The four relays are provided (generally with a Quad Relay Output LLID) as part of the Programmable Relay Option. -
Page 9: Relay Assignments Using Tracer™ Tu
Relay Assignments Using Tracer™ TU Tracer™ TU Service Tool is used to install the Programmable Relay Option package and assign any of the above lists of events or status to each of the four relays provided with the option. (See “Tracer™ TU,” for more information on the Tracer TU service tool) The relays to be programmed are referred to by the relay’s terminal numbers on the LLID board 1A18. -

Low Voltage Wiring / Ice Making (Optional) Technical Data Low Voltage Wiring The remote devices described below require low voltage wiring. All wiring to and from these remote input devices to the Control Panel must be made with shielded, twisted pair conductors. Be sure to ground the shielding only at the panel. - Page 11 Ice Making (Optional) Ice Making Command This is the command to enter ice making. This setting is defined as an Auto/On settings. Setting this to On will command the application into ice building if ice building is enabled and the Chiller is in the “Auto” command mode. Setting the Ice Making command to Auto will command the application to follow the next priority functional mode.

Page 12: External Setpoints & Capacity Outputs (Optional)
External setpoints & capacity outputs (Optional) Technical Data External Chilled/Hot Water Setpoint (ECHWS) The UC800 provides inputs that accept either 4-20 mA or 2-10 VDC signals to set the ECHWS. This is not a reset function. The input defines the setpoint. This input is primarily used with generic BAS (building automation systems). -
Page 13: External Demand Limit Setpoint (Edls)
Like previously, either 2-10 VDC (default) or 4-20 mA inputs are available as option to set External Demand Limit Setpoint. The Demand Limit Setting can also be set via the Tracer TD7 or through digital communication with Tracer (Comm4). The arbitration of the various sources of demand limit is described in the flow charts at the end of this Sound power levels section. -

External setpoints & capacity outputs (Optional) Technical Data ECHWS and EDLS Analog Input Signal Wiring Details Both the ECHWS and EDLS can be connected and setup as either a 2-10 VDC (factory default), 4-20 mA, or resistance input (also a form of 4-2OmA) as indicated below. Tracer TU must be used to set Analog Input Signal LLID type. This is done by a setting change on the Custom Tab of the Configuration View within Tracer TU. -

Page 21: Smart Communication Protocol
Smart Communication Protocol LonTalk™ Interface (LCI-C) UC800 provides an optional LonTalk™ Smart Com Protocol (LCI-C) between the chiller and a Building Automation System (BAS). An LCI-C LLID shall be used to provide “gateway” functionality between a LonTalk compatible device and the Chiller. The inputs/outputs include both mandatory and optional network variables as established by the Sound power levels LonMark Functional Chiller Profile 8040. -

When operating a chiller, there is specific information you need on a day-to-day basis—setpoints, limits, diagnostic information, and reports. Figure 3 – TD7 operator interface report... -
Page 25: Tracer™ Tu
Tracer™ TU The operator interface allows for daily operational tasks and setpoint changes. However, to adequately service chillers Tracer™ TU service tool is required. (Non-Trane personnel, contact your local Trane office for software purchase information.) Tracer TU adds a level of sophistication that improves service technician effectiveness and minimizes chiller downtime. - Page 26 Tracer™ TU Technical Data Criteria: Quantitatively defines the criteria used in generating the diagnostic and, if nonlatching, the criteria for auto reset. If more explanation is necessary a hot link to the Functional Specification is used. Reset Level: Defines the lowest level of manual diagnostic reset command which can clear the diagnostic. The manual diagnostic reset levels in order of priority are: Local or Remote.
