INSTALLING THE

AUTO START

FEATURE

(PC-2 CONTROL ONLY)

IMPORTANT: Always

refer to the wiring diagrams that came with your unit before making electrical con- nections. The diagrams show the most accurate electrical component information.

WARNING: Electric shock hazard

This equipment is powered by high voltage. Always disconnect and lock out the main power source before opening the unit or the electrical enclosure to modify factory settings. Failure to disconnect and lock out the main power source can result in severe personal injury.

If you have a PC-2 microprocessor control, you can automati- cally start and stop the chiller from a remote switching or tim- ing device that has power contacts rated 110VAC, such as the process machine control.

Wiring the device to the chiller is accomplished through a dry contact to the appropriate terminals on the motherboard. After wiring the device to the unit, Auto Start must be enabled by configuring a dip switch on the motherboard.
