  • Page 3: General Recommendations

    Follow proper lockout/tagout procedures to ensure the power cannot be inadvertently energized. • For variable frequency drives or others energy storing component provided by Trane or others, refer to the appropriate manufacturer’s literature for allowable waiting periods for discharge of capacitors. Verify with an FWD 20 appropriate voltmeter that all capacitors have discharged.
  • Page 4 General Recommendations Technical Data 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 link power supplies, including battery backups, UPS and DC-link connections to other frequency converters.

  • Page 7: Programmable Relays

    Programmable Relays 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. The relays contacts are isolated Form C (SPDT), suitable for use with 120 VAC circuits drawing up to 2.8 amps inductive, 7.2 amps resistive, or 1/3 HP and for 240 VAC circuits drawing up to 0.5 amp resistive.

    Relay Assignments Using Technical Data 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 1A10.

  • Page 9: Low Voltage Wiring / Ice Making (Optional)

    Low Voltage Wiring / Ice Making (Optional) 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 10 Ice Making (Optional) Technical Data 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 11: External Setpoints & Capacity Outputs (Optional)

    External setpoints & capacity outputs (Optional) External Chilled Water Setpoint (ECWS) The UC800 provides inputs that accept either 4-20 mA or 2-10 VDC signals to set the external chilled water setpoint (ECWS). This is not a reset function. The input defines the setpoint. This input is primarily used with generic BAS (building automation systems).

  • Page 12: External Current Limit Setpoint (Ecls)

    Like previously, either 2-10 VDC (default) or 4-20 mA inputs are available as option to set External Current 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 section.

  • Page 13: Ecws And Ecls Analog Input Signal Wiring Details

    External setpoints & capacity outputs (Optional) ECWS and ECLS Analog Input Signal Wiring Details Both the ECWS and ECLS 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 14: Chilled Water Reset (Cwr)

    Chilled Water Reset (CWR) Technical Data Functional Description The UC800 shall reset the chilled water temperature setpoint based on return water temperature or outdoor air temperature. The Return Reset and Outdoor Reset functions are standard. The chilled water reset settings are as follows: 1.

  • Page 23 Tracer™ TU 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.
