Checks operation of pump output; either all pumps can be activated or individual pumps. Also tests the associated input such as ¯ow or pressure.

Activates all on/off outputs, all at once or individually.

Pumpdown prevents the low refrigerant alarm during evacuation so refrigerant can be removed from the unit, locks the compressor off. and starts the water pumps.

Charges refrigerant and enables the chiller to run after pumpdown lockout.

Activates external gear main oil pump and auxiliary oil pump (if supplied).

·lead/lag selection

·load balance option

·common sensor option

·lag start/stop timers

·standby chiller option

Owner-Modi®ed CCN TablesÐ The following tables are de- scribed for reference only. For detailed information on CCN operations, consult the CCN supplement for your chiller.

·OCCDEFCS Screen Modi®cations Ð This table contains the local and CCN time schedules, which can be modi®ed here, or on the SCHEDULE screen as described previously.

·HOLIDEF Screen Modi®cations Ð This table con®gures the days of the year that holidays are in effect. See the holiday paragraphs in the Controls section for more details.

·BRODEF Screen Modi®cations Ð This table de®nes the outside-air temperature sensor and humidity sensor if one is to be installed. It also de®nes the start and end of day- light savings time. Enter the dates for the start and end of daylight savings, if required for your location. BRODEF also activates the Broadcast function, which enables the holiday periods de®ned on the LID to take effect.

·Other Tables Ð The ALARMDEF, CONS-DEF, RUNT- DEF, and WSMALMDF screens contain information for use with a CCN system. See the applicable CCN manual for more information on these screens. These screens can only be changed from a CCN Building Supervisor terminal.

CHECK VOLTAGE SUPPLY Ð Access the STATUS 01 screen and read the LINE VOLTAGE: ACTUAL value. This reading should be equal to the incoming power to the starter. Use a voltmeter to check incoming power at the starter power leads. If the readings are not equal, an adjustment can be made by selecting the LINE VOLTAGE: ACTUAL parameter and then increasing or decreasing the value so that the value appear- ing on the LID is calibrated to match the incoming power voltage reading. Voltage can be calibrated only between 90 and 100% of the rated line voltage.

Automated Test Ð Before running this test, be sure that the compressor is in the OFF mode and the 24-v input to the SMM is in range (per line voltage percent on STATUS01 screen). Put the compressor in OFF mode by pressing the STOP pushbutton on the LID.

The automated test starts with a check of the PSIO ther- mistors and proceeds through the rest of the tests listed in the table below. The test not only checks readings, such as temperature and pressure readings, but also lets the operator know if certain devices, such as pumps or relays, are on or off and if all outputs and inputs are functioning. It also sets the refrigerant type.

As each test is executed, the LID display shows which test is running as well as other pertinent data. At the end of each test, the LID displays, OK TO CONTINUE? If a test indicates a problem, error, or device malfunction, the op- erator can choose to address the problem as the test is being done or note the problem and proceed to the next test.

NOTE: If during the control test the guide vanes do not open, check to see that the low pressure alarm is not active. (This causes the guide vanes to close.)

NOTE: The oil pump test will not energize the oil pump if cooler pressure is below ±5 psig (±35 kPa).

When the test is ®nished, or the EXIT softkey is pressed,

the test stops and the CONTROL TEST menu is displayed. If a speci®c automated test procedure is not completed, ac- cess that test by scrolling to it and selecting it to test the function when ready. The CONTROL TEST menu is de- scribed in more detail in Table 8.

Check Pumpout System Controls and Optional Pumpout Compressor Ð The pumpout system con- trols include an on/off switch, a 3-amp fuse, the compressor overloads, an internal thermostat, a compressor contactor, and a refrigerant high pressure cutout. The high pressure cutout is factory set to open at 161 psig (1110 kPa) and reset at 130 psig (896 kPa). Check that the water-cooled condenser has been connected. Loosen the compressor holddown bolts to allow free spring travel. Open the compressor suction and discharge service valves. Check that oil is visible in the com- pressor sight glass. Add oil if necessary.
