Beacon II Smart Controller Features
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 Smart Controller allows complete monitoring and programming of the system. The Controller display has the following buttons: COOLING, DEFROST, PROG REVIEW, MONITOR, ENTER, CLEAR, SETPOINT AND TIME.
The normal LCD display will show the Programmed Box Set-point temperature. Actual Box 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.

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.
Beacon II Smart Controller Base
A terminal strip for wiring connections is located on the base of the Beacon II Smart Controller.
To access this terminal strip, pull both halves of the Beacon II Smart Controller housing apart.
Mounting holes are located in the plastic base.

Wiring
WIRING
All 24 volt wiring must be run separate from the line voltage wiring.
For MULTIPLE independent Refrigeration systems:
All Low voltage wiring must be 18 gauge minimum and must be run separate from high voltage wiring. Themaximum distance from the Beacon II Smart Controller to the Master Evaporator is 1000 ft.
The terminal strip in the Beacon II Smart Controller is labeled similarly to that of the Beacon II boards. Connect the corresponding terminals to those on the Beacon board.
For single Refrigeration system:
Connect MULTI OUT 1 from the Beacon II Smart Controller to the MULTI IN on the Beacon board on the Evaporator. Then connect MULTI IN 1 from the Beacon II Smart Controller to the MULTI OUT on the Beacon board on the Evaporator. See typical wiring diagram at the back of these instructions.
On systems with multiple evaporators the Beacon II Smart Controller must be wired to the Master Evaporator first. DO NOT disconnect the Room sensor from any of the Evaporators.
SINGLE SYSTEM CONNECTION
For the first system, connect MULTI OUT 1 from the Beacon II Smart Controller to the MULTI IN on the Beacon II board on the Evaporator in this first system. Then connect MULTI IN 1 from the Beacon II Smart Controller to the MULTI OUT on the Beacon II board on the Evaporator on this first system. DO NOT disconnect the Room sensor from any of the Evaporators. See typical wiring diagram at the back of these instructions.
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. See typical wiring diagram at the back of these instructions.
On systems with multiple evaporators the Beacon II Smart Controller must be wired to the Master Evaporator first. DO NOT disconnect the Room sensor from any of the Evaporators.
DO NOT CONNECT 24V & C BETWEEN EVAPORATORS.
The Beacon II Smart Controller and the evaporators are then connected in a daisy–chain fashion. (See the wiring diagrams in the back of this manual)
M = Master Evaporator S = Slave Evaporator CU = Condensing unit
A minimum 18 gauge wire should be used. All low voltage wiring must be run separate from high voltage wiring.

POWER SUPPLY
Power Supply
The Beacon II Smart Controller gets it’s 24 VAC power supply from the evaporator. When controlling multiple systems, the Beacon II Smart Controller is powered from the evaporator of only one of the systems. If a power interruption occurs to the system supplying the Beacon II Smart Controller, the Beacon II Smart Controller LCD screen will go blank. The other systems will, however, continue to operate and maintain their box temperature.
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
independent power supply, if power is lost to the Beacon II Smart Controller the systems 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. When this occurs the system will power down and shut off. When the power supply is corrected to 24 VAC, the system will restart after the four-minute hold off period and resume normal operation. The Beacon II Smart Controller LCD display will then be normal.

Initialization of Beacon II Smart Controller
INITIALIZATION of BEACON II SMART CONTROLLER
When power is first applied to the Beacon II Smart Controller it checks the configuration of the system to which it is connected and stores this in its memory. Beacon II Smart Controller checks how many condensing units there are and how many evaporators are connected to each condensing unit. The order in which the units are wired from the multi­out of the Beacon II Smart Controller determines the unit ID (UNI-4) assigned by the Beacon II Smart Controller. This is called initialization. Whenever a system is
added, removed or modified (changing the number of evaporators on a condensing unit), while connected to the Beacon II Smart Controller, it must be re-initialized.
Place all systems in the service mode before initializing the Beacon II Smart Controller. Make sure all wiring changes to the system and the Beacon II Smart Controller are complete and accurate before initializing the Beacon II Smart Controller. Each SLAVE Evaporator must also be programmed as a SLAVE BEFORE the system is initialized. The “SLA” setpoint must be set from the board programming. It cannot be done from the Beacon II Smart Controller.
