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. To clear this condition, the system should be cycled through the “Service”
mode after correction is complete.
On Multiple systems the Alarm contacts on each of the Master Evaporator will also
announce Alarms for that system.
ALARM BUZZER
The ALARM buzzer will sound when an Alarm condition occurs. This buzzer will turn off
when the Alarm condition is cleared. The buzzer can also be silenced at any time by
pressing the “CLEAR” button.
DATA LOGGING
Beacon II Smart Controller logs system data in its memory every 15 minutes. The length of
time it records data is dependent on how many systems are being controlled by the Beacon
II Smart Controller. It keeps writing data to its memory until the memory is full. When the
memory is full it will overwrite its oldest stored data in memory with newly recorded data.
Data recorded:
System Mode, Box Temperature, AUX Temperature, Superheat,
Suction Pressure and the Number of Compressor cycles since
midnight.
Errors and Alarms recorded: Date, Time, System #, Unit #, Error type, Alarm type, Error
duration and Alarm duration
Length of data recorded:
One System = 30 days
Two Independent Systems = 15 days
Three Independent Systems = 10 days
Four Independent Systems =7 days
Recording intervals: Every 15 minutes
All recorded data will have a date/time stamp.
On multiple evaporator systems, the data recorded is from the master evaporator only. This
data is available via connection to a PC through the Beacon II Smart Controller’s RS232
serial port. The data can be viewed on a PC using our Windows based SMART II software
and can be imported into an Excel spreadsheet.
