Temperature, the Current Time of day and the Mode (i.e. COOL, DEFROST or OFF). When multiple systems are being controlled, the system number (i.e. SYS 1, SYS 2, SYS 3, SYS 4) will also be displayed on the LCD. © 2003, Heatcraft Refrigeration Products LLC... - Page 3 Beacon II Smart Controller Features Features of the Beacon II Smart Controller • Monitoring of the complete refrigeration system. • Programming of a variety of parameters for the optimum control of the refrigeration system. • The Beacon II Smart Controller has a Liquid Crystal Display (LCD) which shows: current time, actual box temperature, box temperature set-point and if there is an alarm or fault condition.
-
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
For the second system, connect MULTI OUT 2 from the Beacon II Smart Controller to the MULTI IN on the Beacon II board on the Evaporator in this second system. Then connect MULTI IN 2 from the Beacon II Smart Controller to the MULTI OUT on the Beacon II board on the Evaporator on this second system. -
Page 7: Initialization Of Beacon Ii Smart Controller
Initialization of Beacon II Smart Controller will continue to operate and maintain the box temperature. This occurs only if an external power supply is used on the Beacon II Smart Controller. If the Beacon II Smart Controller LCD displays all 88888 this indicates that the power supply is below 18 VAC. -
Page 8: Programming Beacon Ii Smart Controller
Programming Beacon II Smart Controller • COOLING: Depressing this button will start the system in the cooling cycle immediately (The 4 minutes “Hold Off” is bypassed). This button will illuminate to indicate that the Cooling function is “ON”. System operation will be as described under REFRIGERATION MODE in the Beacon II installation manual. -

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 third try, the Alarm contacts will be closed and an alarm message displayed on the LCD screen. -
Page 13: Smart Defrost
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. -
Page 15: System Defaults
SYSTEM DEFAULTS Following are factory defaults for the parameters which can be programmed in the Beacon II Smart Controller. If the user does not select a setting for any of the following parameters, the default will be used. It is important the user set ALL parameters based of their needs.
