GENERAL NOTES
1. Circuit breaker(s) may be used in place of fuse(s).
2. WARNING-For continued protection against fire hazard replace fuses with the same type and rating only.
3. Unit must be permanently grounded and conform to N.E.C. & local codes.
4. Use copper conductors for field-wiring. Class 1, unless noted. All wire based on 105°C insulation wire, minimum.
5. Wire colors shown may differ from actual unit.
6. Drawing line item reference identification:
- Number in parenthesis near output is location of controlled items. First number is sheet #, second & third are line#.
- No underline indicates normally open (NO) contact, Underline indicates normally closed (NC) contact.
7. All intellectual property, including designs and programming logic are the property of Cold Shot Chillers and is not to be
copied or used without permission from Cold Shot Chillers.
8. Design, specifications, and components are subject to change without notice.
9. Options and alternate design and components may exist and are typically dependent on design and specific parts used
for the system.

* PAGE NOTES
1. Control transformers must be wired/tapped for the appropriate incoming voltage. Depending on design, one dual
voltage or two independent voltages. Operation of system with improperly wired transformer is considered abuse
and resulting damage is not covered by warranty. Transformers may include breaker.
2.
PLC inputs
dependent on system design. 24VDC required to unused inputs.
3.
PLC outputs
dependent on system design:
Y0 - “Cooling Mode Status”. Only available when in cooling cycle and cooling circuit is in operational mode (not in
alarm condition).
Y2 - used on tandem compressor systems only.
Y3 - pump operation (for systems with internal chiller pump or output available for external pump) (optional).
Pump condition status relay or light (optional). Pump relay use dependent on design.
Y4 - hot gas solenoid or relay (optional).
Y5 - on when any compressor is on (used for fan contactor/relay “CR1” and/or liquid solenoid valve purposes).
4.
Switch identification
: “SW#” is switch ID. “SW#-#” is switch ID with position.
SW1 – Mode Selector switch (3 position to include 2 single NO contact blocks. Cooling Cycle may use double NO
contacts for aux purposes or additional stacked NO single block)
SW2 – Process Pump “ON/OFF” switch (2 position to include 1 single NO contact block)
SW3 – Local/Remote switch (2 position to include 1 single NC and 1 single NO contact block)
5. Delta controls with program A1##. (PLC and Temperature Controller must be programmed for system model/design.
6. Terminal blocks are dependent on system design. TBs may or may not be included in system.
7. RS-232 communication available. Refer to instruction guide.
8. Motor Starter auxiliary contacts used with motor starter/contactor combination models. Overload auxiliary contacts
used with overload models.
