The chiller compressor continuously draws large quanti- ties of refrigerant vapor from the cooler at a rate determined by the amount of guide vane opening. This compressor suc- tion reduces the pressure within the cooler , allowing the liq- uid refrigerant to boil vigorously at a fairly low temperature (typically 38 to 42 F [3 to 6 C]).
External Gear Lubrication Cycle (Refer to Item numbers shown in Fig. 5) — Oil reservoir is con- tained in the gear base. The external gear oil pump is mounted below the gear with the cooler/filter . Oil is pumped through an oil cooler/filter to remove heat and any foreign particles.

CONTROLS Definitions ANALOG SIGNAL — An analog signal varies in propor- tion to the monitored source. It quantifies values between operating limits. (Example: A temperature sensor is an ana- log device because its resistance changes in proportion to the temperature, generating many values.
PIC System Components — The Product Integrated Control (PIC) is the control system on the chiller . See T able 1. The PIC controls the operation of the chiller by moni- toring all operating conditions. The PIC can diagnose a prob- lem and let the operator know what the problem is and what to check.

NOTE: This schedule is for illustration only , and is not in- tended to be a recommended schedule for chiller operation. Depending on its operating mode, the chiller uses the fol- lowing occupancy schedules: • LOCAL mode — Occupancy Schedule 01(OCCPC01 on the SCHEDULE screen).
T able 3 — Protective Safety Limits and Control Settings MONITORED P ARAMETER LIMIT APPLICABLE COMMENTS TEMPERA TURE SENSORS OUT OF RANGE –40 to 245 F (–40 to 1 18.3 C) Must be outside range for 2 seconds PRESSURE TRANSDUCERS OUT OF RANGE 0.08 to 0.
2. The motor load ramp loading rate is an operator-configured value that limits the rate at which the compressor motor current or compressor motor load increases. ( LOAD PULL- DOWN %/MIN on the CONFIG screen). T o select the ramp type, highlight the SELECT RAMP TYPE parameter on the CONFIG screen and select either 0( TEMP )o r1( LOAD ).
Oil Cooler — The oil for the external gear and the com- pressor must be cooled while the compressor is running. The compressor oil cooler is a water-cooled, helical, tube-in- shell type heat exchanger . A plug valve is manually set to maintain proper temperatures.
W ater/Brine Reset — Three types of chilled water/ brine reset are available, Reset T ype 1, Reset T ype 2, and Reset T ype 3. They can be viewed or modified on the CON- FIG screen (accessed from the EQUIPMENT CONFIGU- RA TION table). See T able 2, Example 6.
Surge Protection — Compressor surge can be de- tected by the PIC based on operator configured settings. Surge causes amperage fluctuations of the compressor motor . The PIC monitors these amperage swings, and if the swing is greater than the configured setting ( SURGE DELT A PERCENT AMPS ) in one second, then one surge event has occurred.
LEAD/LAG OPERA TION — The PIC control has the ca- pability to operate 2 chillers in the lead/lag mode. It also has the additional capability to start a designated standby chiller when either the lead or lag chiller is not operating and capacity requirements are not being met.
F AUL TED CHILLER OPERA TION — If the lead chiller shuts down because of an alarm (*) condition, it stops com- municating with the lag and standby chillers. After 30 sec- onds, the lag chiller becomes the acting lead chiller and starts and stops the standby chiller , if necessary .
TEMPERA TURE CONTROL DURING ICE BUILD —During ice build, the capacity control algorithm uses the W A TER/BRINE CONTROL POINT minus 5 F (2.7 C) to con- trol the LEA VING CHILLED W A TER temperature. The ECW CONTROL OPTION (see CONFIG screen), the 20 mA DEMAND LIMIT , and any temperature reset option are ig- nored during ice build.
NOTE: The LID does not automatically re-attach to the PSIO module on the chiller . Access the A TT ACH TO NETWORK DEVICE table, scroll to LOCAL , and press the A TT ACH softkey to upload the local device. The software for the local chiller will now be uploaded.
7. Press SELECT to access the holiday table. The LID screen now shows the holiday start month and day , and how many days the holiday period will last. See Fig. 24. 8. Press NEXT or PREVIOUS to highlight HOLIDA Y ST ART MONTH, ST ART DA Y ,o r DURA TION .
If any of these requirements are not met, the PIC aborts the start and displays the applicable pre-start mode of failure on the LID default screen. A pre-start failure does not ad- vance the ST ARTS IN 12 HOURS counter (ST A TUS01 screen).
Safety Shutdown — A safety shutdown is identical to a manual shutdown with the exception that the LID displays the reason for the shutdown, the alarm light blinks continu- ously , and the spare alarm contacts are energized. A safety shutdown requires that the RESET softkey be pressed in order to clear the alarm.
The rotation direction of the motor is shown either on the motor nameplate or on the certified drawing. Information on the required phase rotation of the incoming power for this motor may also be found on the nameplate or drawing. If either is unknown, the correct sequence can be determined as follows.

4. Leak Determination — If an electronic leak detector in- dicates a leak, use a soap bubble solution, if possible, to confirm it. T otal all leak rates for the entire chiller . Leak- age for the entire chiller at rates greater than the EP A (En- vironmental Protection Agency) guidelines or local codes must be repaired.
Inspect W ater Piping — Refer to the piping diagrams provided in the certified drawings and the piping instruc- tions in the 17EX Installation Instructions manual. Inspect the piping to the cooler and condenser . Be sure that flow directions are correct and that all piping specifications have been met.
2. Direct current (as from a welder) can be passed through the winding. The total current should not exceed approxi- mately 50% of the rated full load current. If the motor has only 3 leads, 2 must be connected together to form one circuit through the winding.

PSIO Thermistors Entering chilled water Leaving chilled water Entering condenser water Leaving condenser water Discharge temperature Bearing temperature Motor winding temperature Oil sump temperature 3.
3. Chiller is charged with refrigerant and all refrigerant and all oil valves are in their proper operating position. 4. Gear oil, compressor oil, and motor bearing oil are at the proper levels in the reservoir sight glasses. 5. Compressor oil reservoir temperature is above 140 F (60 C) or refrigerant temperature plus 50° F (28° C).
Under normal conditions, for the self-lubricating bear- ing, the rate of temperature rise should be from 20° to 25° F (11° to 14° C) during the first 10 minutes after starting up and approximately 40° F (22° C) over 30 minutes. The rate of bearing temperature rise is a function of the natural ventilation and operating conditions.
2. Of fset and Angular Alignment — Reverse dial indication or optical methods of alignment (such as lasers) are rec- ommended. A cold alignment and a hot check (with cor- rections, if necessary) are required. The hub flange OD can be used to mount the alignment equipment and is ma- chined to be concentric to the coupling bore.
4. General Recommendations a. Both disc couplings are designed to operate for ex- tended periods without the need for lubrication or main- tenance. V isual inspection of the disc packs is enough to assess the operational condition of the coupling. b. All machinery should be monitored to detect unusual or changing vibration levels.
Instruct the Operator — Check to be sure that the op- erator(s) understands all operating and maintenance proce- dures. Point out the various chiller parts and explain their function as part of the complete system.
NOTE: If the chiller fails to stop, in addition to action that the PIC initiates, the operator should close the guide vanes by overriding the guide vane target to zero (to reduce chiller load) and then by opening the main disconnect. Do not at- tempt to stop the chiller by opening an isolating knife switch.

2. T o determine economizer/storage vessel pressure, attach a 30 in.-0-400 psi (-101-0-2760 kPa) gage to the vessel. 3. Refer to Fig. 32 for valve locations and numbers.
T ransferring Refrigerant into the Cooler/ Condenser/Compressor Section — These steps de- scribe how to transfer refrigerant from the economizer/ storage vessel into the cooler/condenser/compressor section. This is normally done to prepare for service work on the economizer/storage vessel.
Refrigerant HFC-134a MUST NOT be mixed with air or oxygen and pressurized for leak testing. In general, this refrigerant should not be allowed to be present with high concentrations of air or oxygen above atmo- spheric pressures, because the mixture can undergo combustion.

9. Place a clean, lint-free cloth on a smooth, sturdy work surface. Place the seal housing assembly on the cloth with the face of the contact sleeve in contact with the cloth. While one person pushes down on the housing to compress the spring, another person must remove the snap ring.
Chiller Alignment ALIGNMENT METHODS — There are several established procedures for aligning shafts. The dial indicator method is presented here since it is considered to be one of the most accurate and reliable. Another faster and easier method for alignment involves using laser alignment tools and comput- ers.
2. Parallel in elevation — This alignment is also made with shims, but it cannot be made while there is angular mis- alignment in elevation. 3. Angular in plan — This position can easily be lost if placed ahead of the two adjustments in elevation.
If the larger opening remains the same but changes from side to side, the shafts are in perfect alignment. The change in opening is due entirely to coupling runout, as above, or to a burr or other damage to the coupling face. If the larger opening remains the same, and remains on the same side, the amount is entirely shaft (net) misalignment.
4. Loosen all holddown bolts except the pivot bolt. T urn the screw jack until the rear end of the equipment moves against the indicator by the desired amount. 5. T ighten the holddown bolts and recheck the indicator . If the reading has changed, loosen the three bolts and re- adjust.
When using brackets, the diameter in the alignment for- mula (see Near Final Alignment, Connecting Angular Mis- alignment section) will be that of the circle through which the dial indicator rotates. 1. Shut down the chiller . 2. W ith chiller at operating temperature, quickly install brackets.
WEEKL Y MAINTENANCE Check the Lubrication System — Mark the oil level on the compressor reservoir sight glass, and observe the level each week while the chiller is shut down. If the level goes below the lower sight glass, the oil re- claim system will need to be checked for proper operation.
5. Open the drain located on the shell of the cooler/filter . Run a hose from the drain to a bucket to catch the oil. 6. Once the pressure has been relieved and the oil drained, loosen the bolts that hold the cover on the filter body . Remove the old filter cartridges and replace with a new filter cartridge.
The lubricant should be drained while the gear is at op- erating temperature. The gear drive should be cleaned with a flushing oil. Used lubricant and flushing oil should be com- pletely removed from the system to avoid contaminating new oil. T o change the oil in the external gear: 1.
CLEANLINESS — On open ventilated motors, screens and louvers over the inlet air openings should not be allowed to accumulate any build-up of dirt, lint, etc.
7. When removing the labyrinth seals, note the position of the anti-rotation button located on the inside of the top half of the seal. Pull up the garter spring surrounding the floating labyrinth seal and carefully slip out the top half. Rotate the garter spring until the lock is visible.
14. Reinstall the bearing housing split bolts. Before torqu- ing bearing housing cap bolts, rotate the shaft by hand while bumping the bearing housing with a rubber or raw- hide mallet in the horizontal and axial planes to allow the bearings to align themselves to the shaft journals.
Fill the gear drive to the recommended oil level with heated Shell VSI grade 68 oil or its equivalent, heated between 1 10 and 120 F (43 and 49 C). Do not overfill.
Water must be within design flow limits, clean, and treated to ensure proper chiller performance and reduce the po- tential of tube damage due to corrosion, scaling, ero- sion, and algae. Carrier assumes no responsibility for chiller damage resulting from untreated or improperly treated water.
temperature control overrides, hot gas bypass, surge al- gorithm status, and time schedule operation. Refer to Fig. 14 and T able 2, Examples 1 1-14. • The control test feature checks for proper ope.
4. A high pressure point can also be calibrated between 240 and 260 psig (1655 and 1793 kPa) by attaching a regu- lated 250 psig (1724 kPa) pressure (usually from a ni- trogen cylinder).
