7 Fa ctory-Mounted Star ter or V ariable Fr e- quenc y Drive (Opt ional) — The starter allow s for the proper start and disconnect of electrical energy for the com- pressor-motor , oil pump, oil heater , and control panel. Storage V essel (Optional) — There are 2 sizes of storage vessels available.
8 Flow to the motor cooling system passes through an orifice and int o the motor. Once past t he orif ice, the r efrig erant is directed over the motor by a s pray nozzle. The refrigerant collec ts in the bot tom of the motor cas ing and is th en drained back into the cool er through the motor refri gerant drain line.
9 ST ARTING EQ UIPMENT The 19XR requires a motor starter t o operate the centrifugal hermetic compressor motor, t he oil pump, and various auxilia- ry equipment.
10 There is a display on the f ront of the Benshaw , Inc., solid- state starters that is useful for troubleshooting and start er checkout. The display i ndicates: • voltage to the SCRs • SCR contr.
11 General — The 19XR hermetic centrifugal liquid chiller contains a microproces sor-based control ce nter that moni tors and controls all operations of the chiller (see Fig. 9). T he microprocessor control system matches the cooling capacity of the chiller to the cooling load while providing state-of-t he-art chiller protection.

33 PIC II System Functions NOTE: W ord s not part of paragraph headings and printed in all capital letters can be viewed on the CVC/ICVC (e.g., LOCAL, CCN, RUNNING, ALARM, etc.). W ords printed both in all capital letters and italics c an also be viewed on the CVC/ICVC and are parameters ( CONTROL MODE, T ARGE T GUIDE VA N E P O S , etc.
34 The PROPORTIONAL ECW GAIN c an be adjusted on t he CVC/ICVC display for values of 1, 2, or 3; t he default setting is 2. Increase this s etting to increase guide vane response to a change in entering chilled w ater temperature.
35 Table 3 — Protective Safety Limits and Control Settings Shunt T rip (Option) — The function of the shunt trip option on the PIC II is to act as a safe ty trip. The shunt trip is wired from an output on the I SM to a shunt trip equipped mo- tor circuit breaker .
36 Ramp Loading — The ramp loading control slows down the rate at which the compre ssor loads up. This control can pre- vent the compressor from loading up during t he short period of time when t he chiller is started and t he chilled wat er loop has to be brought down to CONTROL POINT .
37 Table 4 — Capacity Ove rrides Alarm (T rip) Output Cont acts — O ne se t of al arm contacts is provided in the starter . The contact ratings are pro- vided in the certified drawings. The contacts are located on ter- minal strip J9, terminals 15 and 16.
38 Condenser Freeze Prevent ion — This control algo- rithm helps prevent condense r tube freeze-up by energizing the condenser pump relay . The PIC II cont rols the pump and, by starting it, helps to pre vent the w ater in the c ondenser from freezing.
39 (see wiring diagrams or certi fied drawings). The temperatur e sensor must be wired to terminal J4-13 and J4-14. T o configure Reset T ype 2, enter the temperature of the re mote sensor at the point where no temperature reset will occ ur ( RE MOTE T EMP –> NO RESET ).
40 Capacity Overrides. Both of these correc tive actions try to reduce the lift exper ienced by the compressor and help prevent a surge condition. Surge Pre vention Algorithm with VFD — This is an operator configurable feat ure that can determine if lift con- ditions are too high for the compressor and then take corrective action.
41 NOTE: The l ead/lag function can be confi gured on th e LEAD- LAG screen, which is acce ssed from the SER VIC E menu and EQUIPMENT SER VICE table. See T able 2, Example 20. Lead/lag status during chiller operation can be viewe d on the LL_MAINT display screen, which is accessed from the SER- VICE menu and CONT ROL ALGO RITHM ST A TUS t able.
42 Standby Chiller Configuration and Operation — A chille r is designated as a standby chiller when its LEADLAG: CONFIG- URAT ION value on the LEA DLAG sc reen is se t to “ 3.
43 Ice Build Contr ol — The ice build control option auto- mati cally se ts the CONTROL POINT of the chiller to a temper- ature that allows i ce building for t hermal stora ge. NOTE: For ice build control to operat e properly , the PIC II must be in CCN mode.
44 stop the chiller when a specific time period on the ice build schedule is not set for i ce build. 4. Entering Chilled W a ter T emperature and ICE BUILD Contacts — Compre ssor operation terminate.
45 Service Operation — An overview of the tables and screens available for the SER VICE function is shown in Fig. 18. TO ACCESS THE SER VICE SCREENS — Wh en the SER- VICE screens are accessed, a password must be entered. 1. From the main MENU s creen, pres s the softkey .

53 Chiller Deh ydration — Dehydration is recomme nded if the chiller has been open for a considerable period of time, if the chiller is known to contain moisture, or if there has bee n a complete loss of chiller holding charge or refrigerant pressure.
54 2. On low-voltage compressors (600 v or less) c onnect a voltmeter ac ross the power wires to the compressor start - er and m easure the voltage. Compare this reading to the voltage rating on the compressor and star ter nameplates. 3. Compare the ampere rating on the starter na meplate to rating on the compressor nameplate .
55 MECHANICAL ST AR TER 1. Check all field wiring connections for tightness, clear- ance from moving parts, and c orrect connection. 2. Check the contact or(s) to ensure th ey move freely . Check the m echan ical inter lock betw een contac tors to e nsur e that 1S and 2M contactors cannot be closed at the same time.
