Fan Boards — At least one fan board is installed in each unit. See Fig. 11 and 12. There are two types of fan boards. One with and one without an analog output signal for the low ambient temperature head pressure control fan speed controllers. If a unit does not have low ambient temperature head pressure control installed, it will not have the analog connection terminals.

It is important when connecting to a CCN communication bus that a color-coding scheme be used for the entire network to simplify the installation. It is recommended that red be used for the signal positive, black for the signal negative, and white for the signal ground. Use a similar scheme for cables containing different colored wires. At each system element, the shields of its communication bus cables must be tied together.
Fig. 16 — ComfortLink™ CCN Communication Wiring Service Tool or ComfortVIEW™ software. The tables are the CtrlID (Controller Identification) configuration table and the USERCONF (User Configuration) table. See Tables 15 and 16. NOTE: Always perform an Upload to obtain the latest configuration before making configuration table changes.
such as ComfortVIEW™ software, the Autodial Gateway or TeLINK is already set as the alarm acknowledger for the CCN network then this decision should be set to No. NOTE: The display must be in Network mode and connected to the primary CCN bus and this decision set to Yes for alarm acknowledgement to be enabled. Allowable Entries: No Yes Default Value: No BROADCAST ACKNOWLEDGER — This configuration is used to indicate whether the Touch Pilot display will act as the broadcast acknowledger for its CCN bus.
Control Type will be Local. The Operating Type variable will change to L-Sched (Local Schedule). The schedules consist of 8 user-configurable occupied time periods. The control supports time schedules for local control, remote control, and ice building. These time periods can be flagged to be in effect or not in effect on each day of the week. The day begins at 00.00 and ends at 24.00. The machine will be in unoccupied mode unless a scheduled time period is in effect.

Switching the Enable/ Off/Remote Contact switch to the Enable or Remote Contact position (external contacts closed) will force the unit into an occupied state. In this mode, all CCN network force commands, except the Emergency Stop Command will be ignored.
Two Internal Time Schedules are available and must be field programmed. Time Schedule 1 (SCH1) is used for single set point On-Off control. Time Schedule 2 (SCH2) is used for dual set point On-Off and Occupied-Unoccupied set point control. The control will use the operating schedules as defined under the Time Clock mode in the Navigator display module. ITEM ITEM EXPANSION PATH Operating Control Operating OPER Type ModesSLCTOPER Table 22 — Configuring Schedules with Navigator™ Display ITEM OCC.1 UNO.
To configure this option for the Navigator™ display: The Occupancy Supervisory Part table name (OCC1P01S) number must be changed to configure the unit to broadcast a Global Time Schedule. The Schedule Number can be set from 65 to 99 (OCC1P65S to OCC1P99S). When OCC1PxxS is set to a value greater than 64, an occupancy flag is broadcast over the CCN every time it transitions from occupied to unoccupied or vice-versa.
The following equation is used to control the set point. See Fig. 20. Fahrenheit Set Point = 10 + 70(mA – 4)/16 (deg F) Celsius Set Point = –12.2 + 38.9(mA – 4)/16 (deg C) To configure this option while using a Touch Pilot display: Set Point 1 (Cooling Setpoint 1, CSP.1) during the occupied period while operating under Time Schedule 1 (SCH1). If the Time Schedule 2 (SCH2) is in use, the unit’s active set point is based on Cooling Set Point 1 (Cooling Setpoint 1, CSP.

Under normal operation, the chiller will maintain a constant entering or leaving fluid temperature, based on the configuration, approximately equal to the chilled fluid set point. As the cooler load varies, the cooler fluid temperature difference will change in proportion to the load. For example, if the chiller was selected for a Entering to Leaving Water Temperature difference of 10 F (5.5 C) at full load, at 50% load the temperature difference would be 5 F (2.2 C). See Fig. 22.

Dual Chiller Sequence of Operation — With a com- mand to start the chiller, the master chiller determines which chiller will become the lead chiller based on the configuration of Lead Lag Select, LLBL and Lead/Lag Balance Data, LLBD. The lead chiller is always started first and the lag chiller is held at zero percent capacity by the master chiller forcing the lag demand limit value to 0%.

The discharge superheat leaving the compressor is maintained between approximately 18° and 25° F (10° and 14° C), or less. Because EXV status is communicated to the Main Base Board (MBB) and is controlled by the EXV modules, it is possible to track the valve position. The unit is then protected against loss of charge and a faulty valve. During initial start-up, the EXV is fully closed.

Once the calculated position of the slide valve reaches 100% circuit capacity, the control will try to increase capacity again if the compressor current continues to increase. The control will continue to load the compressor until the compressor current no longer increases. At that time the control will energize both solenoids and the circuit will be considered fully loaded.
5. When the compressor starts successfully, observe the cooler pressure. When the pressure reads 10 psig (68.9 kPa), turn the Emergency Switch (SW2) to the OFF position. The compressor should stop. 6. Open the liquid line service valve and allow the unit to restart normally. If low oil level alarms persist, continue with the following steps. 7. If none of the previous steps were successful, the unit is low on oil charge. Add oil to the oil separator using the 1/ in.

DX COOLER FREEZE PROTECTION — Coolers can be ordered with heaters installed in the factory. If equipped, the main base board based on the outdoor-air temperature and the entering and leaving water thermistors controls the cooler heaters.

APPENDIX G — BACNET COMMUNICATIONS OPTION 6 5 7 8 2 34 5 6 10's 1 9 0 2 34 7 8 9 0 1 The following section is used to configure the UPC Open controller which is used when the BACnet* communications option is selected. The UPC Open controller is mounted in a separate enclosure below the main control box. TO ADDRESS THE UPC OPEN CONTROLLER — The user must give the UPC Open controller an address that is unique on the BACnet network. Perform the following procedure to assign an address: 1.
APPENDIX G — BACNET COMMUNICATIONS OPTION (cont) CONFIGURING THE BAS PORT FOR BACNET MS/ TP — Use the same baud rate and communication settings for all controllers on the network segment. The UPC Open controller is fixed at 8 data bits, No Parity, and 1 Stop bit for this protocol's communications. If the UPC Open controller has been wired for power, pull the screw terminal connector from the controller's power terminals labeled Gnd and HOT.
APPENDIX G — BACNET COMMUNICATIONS OPTION (cont) Fig. E — BT485 Terminator Installation temperature rating specifications list two acceptable alternatives. The Halar specification has a higher temperature rating and a tougher outer jacket than the SmokeGard specification, and it is appropriate for use in applications where the user is concerned about abrasion. The Halar jacket is also less likely to crack in extremely low temperatures.
APPENDIX G — BACNET COMMUNICATIONS OPTION (cont) Table D — Open System Wiring Specifications and Recommended Vendors WIRING SPECIFICATIONS Wire Type RECOMMENDED VENDORS AND PART NUMBERS Connect Air Contractors Belden RMCORP Wire and Cable International Description 22 AWG, single twisted shielded pair, low capacitance, CL2P, TC foam FEP, plenum rated. See MS/TP Installation Guide for specifications.
APPENDIX G — BACNET COMMUNICATIONS OPTION (cont) If the UPC Open controller is used with the chiller application of Lead/Lag/Standby, all chillers and UPC Open's CCN element numbers must be changed to a unique number in order to follow CCN specifications. In this application, there can only be a maximum of 3 UPC Open controllers on a CCN bus. For the CCN Alarm Acknowledger configuration, the UPC Open controller defaults to CCN Acknowledger.
