6 Table 1 — Setup Menu SETUP MENU BUTT ON FUNCTION REGIONAL This button specifies the time and date format and th e base unit of measure. Time displa y can be configured as 12-hour AM/PM setting or as a 24-hour setting.
7 Setting the Time and Date — The Comfort Link™ control has a time and date function. This can be useful for diagnostics to determine when alarms occur . The control is factory config- ured for the proper date and is set for the Eastern Time Zone.
8 This indicates an initialization period while the Navigator™ display initiates communication with the Main Base Board. Once communication is establis hed, the default rotating dis- play will be shown.
9 Table 2 — Comfort Link™ Navigator™ Disp lay Menu Structure CONTR OLS General — The 30XW water -cooled liquid chillers contain the Comfort Link™ electronic control system that controls and monitors all operations of the chiller . The control system is composed of several components as listed in the following sec- tions.
10 Table 3 — Main Base Board Inputs an d Outputs LEGEND Compressor Pr otection Module (CPM) — T here is one CPM per compressor . See Fi g. 9. The device controls the compressor contactors, oil sole noid, and loading/unloading the solenoid.
11 Table 4 — DIP Switch 1 (S1) Inputs The CPM board DIP switch S2 setting determines the must trip amps (MT A) setting. See Appendix D for DIP switch set- tings. The MT A setting which is calculated using the setting s S2 must match the MT A setting in the software or an MT A alarm will be generated.

13 Electronic Expansion V alve (EXV) Board — The 30XW150-325 units have one EXV board. The 30XW350,400 units have one EXV board per circuit. See Fig. 10. The board is responsible for monitoring the suction gas temperature and economizer gas temperature thermistors.
14 Table 6 — EXV1 Board Inputs and Outputs (30XW150-325) Table 7 — EXV1,2 Board Inputs and Outputs* (30XW350,400) *“X” denotes the circuit: 1 = Circuit A; 2 = Circuit B.
15 ML V/Condenser Boar d — One auxiliary board is op- tionally installed in each unit. See Fig. 1 1. The auxiliary board contains an analog output for head pressure control and dis- crete outputs for minimum load control.
16 Enable-Off-Remote Contact Switch (SW1) — This switch is installed in all units and provides the owner and service person with a local means of enabling or disabling the machine. It is a 3-position switch and it is used to control the chiller . When switched to the Enable position, the chiller will be under its own control.
17 Table 9 — Energy Management Module (EMM) Inputs and Outputs * A field-supplied 1/2 w att 250 ohm resistor is required across terminals TB6-1,2 (CH6) and/or TB6-3, 4 (CH5). Local Equipment Netw ork — Information is trans- mitted between modules via a 3-wire communication bus or LEN (Local Equipment Network) .
18 Carrier Comfort Network ® (CCN) Interface — All 30XW units can be connected to a CCN system, if desired. The communication bus wiring is a shielded, 3-conductor cable with drain wire and is field supplied and installed. The system elements are connected to the communication bus in a daisy chain arrangement.
19 Table 12 — Touch Pilot Contr oller Identification Configuration Table Table 13 — Touch Pilot™ User Configuration (USERCONF) Table BA C KL I GH T AL W A YS O N? — This configuration is used to keep the backlight on continuously or to turn it off after 60 seconds with no activity .

21 T able 14 summarizes the unit control type and stop or go status with regard to the following parameters: • Operating type: this is selected by using the start/stop button on the front of the user interface. • Remote start/stop contacts: these contacts are used when the unit is in remote operating type (Remote mode).
22 Table 15 — Config uring the Sche dule with Touch Pilot Display Holiday Schedule — For the T ouch Pilot display , the control allows up to 16 holiday periods.
23 commands, except the Emergency S top Command will be ignored. The Run S tatus variable will indicate the current sta- tus of the machine (OFF , RUNNING , DELA Y , or READY), depending on the position of the Remote/Of f/Enable Switch closure. The Chiller Occupied? variable will change to YES.
24 T ime Schedule — W ith T ime Schedule Operating T ype con- trol, the machine operates unde r a local schedule programmed by the user as long as the Enab le/Off/Remote Contact switch is in the Enable or Remote Contact position (external contacts closed).
25 CCN Control — W ith CCN Operating T ype control, the ma- chine operates under CCN control as long as the Enable/Off/ Remote Contact Switch is in th e Enable or Remote Contact position (external contacts closed.) T o operate under this Operating Control, OPER must be set to CCN CONTROL.

27 T o conf igure this option while using a Navigator display: Dual Switch — When Set Point Select ( Setpoint Select , SP .S E ) is configured to 4 (Dual Se tp Sw), the unit’ s active set point is based on Cooling Set Point 1 ( Cooling Setpoint 1 , CSP .
28 Cooler Pump Control — It is required for all chillers that the cooler pump control be utilized unless the chilled water pump runs continuously or the chilled water system contains a suitable concentration of antifre eze solution.
29 Machine Start Delay — An option to delay the start of the machine is also availa ble. Th is parameter is useful in keep- ing multiple machines from starting at the same time in case of a power failure. The parameter has a factory default of 1 minute.
30 between the master and the slave remains less than the Lead/ Lag Balance Delta, the chiller designated as the lead will remain the lead chiller . The L ead/Lag changeover between the master and the slave chiller due to hour balance will occur dur- ing chiller operating odd days, such as day 1, day 3, and day 5 of the month, at 12:00 a.

39 Demand Limit — Demand limit is a feature that allows the unit capacity to be limited during periods of peak energy usage. This allows the owner to keep energy costs down.
40 In the following example, 2-step demand limit based on capacity is desired with the first switch closure limiting the capacity to 60%. The second switch closure is to limit the capacity to 40%. Demand Limit Switch 1 is 60% and Demand Limit Switch 2 is 40%.
41 T o configure this option with the Navigator display: In the following example, a 4 mA signal is Demand Limit for compressor current is 2000 amps and a 20 mA Demand Limit signal corresponds with a compressor current of 0 amps. The 4 to 20 mA signal is connected to TB6-1 and TB6-2.
42 Set this variable to 2 for stand-alone units that are not con- nected to a CCN. W ith this configuration, daylight saving time and holiday determination will be done without broadcasting through the bus. This variable can only be changed when using the T ouch Pilot display , ComfortVIEW™ software, or Network Service T ool.
43 RE - AL A RM T I ME — This variable specifies the amount of time that will be allowed to el apse between re-alarms. A re- alarm occurs when the conditions that caused the initial alarm continue to persist for the number of minutes specified in this decision.
44 Override #2: Circuit A Low Saturated Suction T emperature in Cooling Override #3: Circuit B Low Saturated Suction T emp erature in Cooling These overrides attempt to avoi d the low suction temperature alarms and are active only when the compressor is running beyond the fully unloaded level.
45 Override #14: Slow C hange Override — This override pre- vents compressor stage changes when the leaving temperature is close to the control point and slowly moving towards it.
46 Table 34 — 30XW Compre ssor Nominal Capacity Override #59: Circuit A Low Oil Level Override #60: Circuit B Low Oil Level — This override is only effective when the circuit is not running. The override will prevent the circuit from starting up with a low oil level.

54 OPERA TION Sequence of Operation — With a command to start the chiller , the cooler and conde nser pumps will start. After verifying water flow , the control will monitor the entering and leaving water temperatures. If the need for mechanical cooling is determined, the control decides which circuit and compres- sor to start.
55 ST AR TUP DELA Y IN EFFECT — T hi s m od e is c he c ke d for when the unit is started. This mode is active when the Min- utes Off T ime ( Unit Off to On Delay , DEL Y ) timer is active. The unit will not start until the timer has expired. The mode will terminate when the timer expires.
