Indicates a possible hazardous situation which will result in death or serious injury if proper care is not taken.

Indicates a potentially hazardous situa-tion which will result in possible injuries or damage to equipment if proper care is not taken.

Identifies a hazard which could lead to damage to the machine, damage to other equipment and/or environmental pollu-tion if proper care is not taken or instruc-tions and are not followed.

Highlights additional information useful to the technician in completing the work being performed properly.

External wiring, unless specified as an optional connection in the manufacturer’s product line, is not to be connected inside the control cabinet. Devices such as relays, switches, transducers and controls and any external wiring must not be installed inside the micro panel. All wiring must be in accor-dance with Johnson Controls’ published specifications and must be performed only by a qualified electrician. Johnson Controls will NOT be responsible for damage/problems resulting from improper connections to the controls or application of improper control signals. Failure to follow this warn-ing will void the manufacturer’s warranty and cause serious damage to property or personal injury.

NOTES1. This wiring diagram describes the standard elec-

tronic control scheme for use with a steam turbine drive. For details of field control modifications, refer to Product Form 160.67-PW2.

2. Field wiring to be in accordance with the National Electrical Code as well as all applicable codes and specifications. Refer to Form 160.67-PW5 (Top Mount Steam Condenser) and Form 160.67-PW4 (Floor Mount Steam Condenser) for field wiring connections.

3. Numbers along the left side of the diagram are line identification numbers. The number along the right side indicates the line number location of relay contacts. An underlined contact location signifies a normally closed contact.

4. Main Control Panel Class 1 field wiring terminal connection points are indicated by numbers with-in a rectangle i.e. 15 . Main Control Panel factory wiring terminal connection points are indicated by numbers within a triangle i.e. 5 . Component Terminal connection points are indicated by num-bers within a circle i.e. CI . Numbers adjacent to circuit lines are the circuit identification numbers. Power Panel wiring terminal connection points are indicated by numbers within a hexagon i.e . L1 . Steam Condenser junction box wiring termi-nal connection points are indicated by numbers within a diamond i.e. 80 .

5. To cycle unit ON and OFF automatically and pro-vide a controlled shutdown. Install a cycling de-vice between terminals 1 & 13 . (Line 33A) (see Note 9). If a cycling device is installed, jumper must be removed between terminals 1 & 13 .

6. Fuse sizes and motor overload setpoints depend on voltage of single point power supply. See chart on field connection diagram on door of panel.

7. To stop unit and not permit it to start again, after a controlled shutdown install a stop device between terminals 1 & 8 (Line 32A) (see Note 9). A remote start-stop switch may be connected to ter-minals 1 , 7 ,& 8 . (Line 32A) (see Note 9). Re-mote switches are operative only in the "remote" operating mode.

8. Contact rating is 5 amps resistive at 120 volts AC or 240 volts AC.

9. Device contact rating to be 5 milliamperes at 115 volts AC.

10. Three phase power must be properly phased. L1, L2, & L3 corresponding to phase sequence A, B, & C.

11. Contact rating is 5 Amps resistive at 250 volts AC & 30 volts DC 2 Amp inductive (.4 PF) at 250 volts AC & 30 volts DC.

12. Each 115 VAC field-connected inductive load I.E. relay coil, motor starter coil, etc. shall have a transient suppressor wired in parallel with its coil, physically located at the coil. Spare transient sup-pressor and control circuit fuses are supplied in a bag attached to the green ground screw in the lower left corner of the control panel.

13. Turbine auxiliary oil pump, oil cooler, oil sensors & turbine oil safety logic are supplied only on turbines with pressurized lubrication.

14. If optional chilled and condenser liquid low pres-sure differential switches are installed, panel must be configured for "digital" flow sensor. Refer to Form 160.67-O1.

15. Refer to Operators Manual for a detailed descrip-tion of chiller operation & all wanring/shutdown operating points.

16. Do NOT apply voltage on field wiring terminal blocks TB4 or TB6. All 115 volt AC power is fed from terminals 1 & 2.

17. Do NOT apply voltage on field instrument wiring terminal block TB7. All instrument loop power is supplied from terminals 325, 327, & 329 .

18. YST chillers are supplied with automatic starting as standard. Manual starting is not recommended and will be supplied by special quote only.

19. Manual motor protector auxiliary contact is open when operator is in the OFF position, closed when operator is in the ON or any tripped position.

20. Liquid injection solenoid is supplied on K3, K4, & K7 compressors only.

21. Optional wiring between the chiller terminal box and the floor mounted steam condensor is sup-plied by the factory for installation in conduit by the electrical installation contractor.

22. For standard top mounted steam condensor cables 28, 30, and 42 are connected directly to devices shown after the steam condensor is installed in the field.

JOHNSON CONTROLS 7


23. For standard top mounted steam condenser, the harnesses from the main junction box and power panel are connected directly to the steam condens-er box after the steam condenser is installed in the field.

24. For inlet steam pressures up to 200 PSIG, PT-170 Range is 0-300 PSIG and PT-172 Range is 0-100 PSIG. For inlet steam pressures above 200 PSIG, PT-170 Range is 0-500 PSIG and PT-172 Range is 0-150 PSIG.

25. Manual motor protector signaling contact is closed when operator is in the off or on position, open when operator is in any tripped position. Trips may be caused by thermal overload, short circuit, under-voltage, or shunt.
