2 The Beacon II Smart Controller performs all the standard Beacon functions with the additional benefit of: a) Remote mounting for easy access b) Remote monitoring and programming c) Controlling four completely separate systems d) Logging data e) Smart Defrost f) Access via PC or modem g) Has buzzer to signal alarms h) Locking keypad Beacon II Smar[...]

3 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 th[...]

4 INST ALLA TION 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. A terminal stri[...]

5 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 t o the Master Evaporator is 1000 ft. The terminal strip in the Beacon II Smart Controller i s labeled similarly t[...]

6 For the second system, connect MUL TI OUT 2 from the Beacon II Smart Controller t o the MUL TI IN on the Beacon II board on the Evaporator in this second system. Then connect MUL TI IN 2 from the Beacon II Smart Controller t o t h e MUL TI OUT on the Beacon II board on the Evaporator on this second system. See typical wiring diagram at the back o[...]

7 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 V AC. When this occurs the system will power down and shut off. When the power supply is corre[...]

8 • 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 REFRIGERA TION MODE in the Beacon II installation manual. Pressing the COOLING button whil[...]

9 • SUPRHT – Superheat: 4 to 20 ° F . Use “SETPOINT” slide-bar to select desired superheat temp., then press “ENTER.” If multiple evaporators are connected, use the “+” button to set other evaporators on this system. • SMT DFT : Smart Defrost: On/Of f. Use “SETPOINT” slide-bar to turn it ON or OFF , then press “ENTER” - ([...]

10 • EXVSET - Expansion valve step setting (Stepper Motor setting 0 to 255 steps: use + button to check other evaporators if Master/slave) • SUCTMP – Evaporator Suction temperature (Measured by the Suction Sensor) • SSVTMP – Saturated Suction temperature at the Evaporator (Determined by Suction T ransducer) • SUCPRE – Evaporator Sucti[...]

11 • *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. When the error condition is corre[...]

12 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 displ[...]

13 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. This information is stored to the PC hard dr[...]

14 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. The stored data can be viewed in an Excel spreadsheet. Recommended Requirements PC with a 233 Mhz clock[...]

15 SYSTEM DEF AUL TS 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.
