Page 4: Installation
Installation INSTALLATION The Beacon II Smart Controller should be installed in a location where the large Liquid Crystal Display (LCD) can be viewed easily, yet is secure and vibration free. Because of the LCD screen, the Beacon II Smart Controller should not be mounted where it will experience temperatures below 40 F or above 100 F. -
Page 5: Wiring
WIRING All 24 volt wiring must be run separate from the line voltage wiring. All Low voltage wiring must be 18 gauge minimum and must be run separate from high voltage wiring. The maximum distance from the Beacon II Smart Controller to the Master Evaporator is 1000 ft. -
Page 6: Power Supply
The Beacon II Smart Controller can be supplied with it’s own power supply by using a 24 VAC Universal Plug-in Power Source with a minimum of 300 mA. When powered by an... -

Wiring Error & Alarm Codes *SPSEN - • Suction pressure transducer shorted, open or not installed *ODSEN - • Outdoor temperature sensor shorted *SUPLO - • Superheat too low *SHTDN - • Compressor shutdown (High or low refrigerant pressure or low oil pressure) The error code will flash alternately with the normal display information. -
Page 12: Alarm Buzzer
Alarm Buzzer & Data Logging The system will pumpdown, cycle off and try to restart for three consecutive times. Each try will be after the 4 minutes “Hold Off” period, for the following fault conditions. Oil pressure High pressure or low pressure cutout (or any other compressor safeties) After the fourth try, the Alarm contacts will be closed and an alarm message displayed on the LCD screen. -

Real-time data can also be recorded and stored on a Desktop PC while the PC is connected to the Beacon II Smart Controller. The PC will continuously request information from the Beacon II Smart Controller regarding system operation and setup and record this data every minute, in an Excel spreadsheet. -
Page 14: Pc & Modem Access
PC And Modem Access PC & MODEM ACCESS For access to the system from a PC directly or via a modem, the SMART II Software must be purchased and installed on your PC. With PC access, ALL system settings can be monitored, changed or logged from a remote location. -
