FAD - 4 DIGITAL LOADCELL JUNCTION BOX 02.05.00 FAD4_2RM 2 7 of 20
EXAMPLE: For a 0,1234 mV/V loadcell deadload output the data downloaded must be 001234.
Master transmission :
STX A A 001234 0 0 ETX
Master transmission:
STX A ? = 3 ETX
Slave response:
STX A ? E WAIT.. 2 3 ETX
a.
DEADLOAD CALIBRATION (WEIGHT)
When this command is received the FAD-4 will measure the weight of the empty scale by
averaging 32 conversions. This DEADLOAD average will be held in the ZERO CALIBRATION
memory.
Master transmission:
STX ADD a BCS2 BCS1 ETX
Poll the slave by using command ‘?’. Possible response messages: ‘WAIT..’ or ‘ERR 91’ .
Slave returns to normal weight output mode after the command is completed.
THE VALUE IS NOT SAVED IN EEPROM UNTIL A STORE COMMAND IS ISSUED.
B. SPAN CALIBRATION (ELECTRONIC, mV/V)
Used to download the capacity of each loadcell for SPAN factor computation .
The command must be preceded by command “C”.
Master transmission:
STX ADD B yyyyy BCS2 BCS1 ETX
yyyyy: 5 digits without decimal point (ASCII decimal)
Poll the slave with command ‘?’. Possible responses: “WAIT..” or “ERR 90” or “ERR 91”.
Slave returns to normal weight output mode after the command is completed.
THE VALUE IS NOT SAVED IN EEPROM UNTIL A STORE COMMAND IS ISSUED.
b.
SPAN CALIBRATION (WEIGHTS)
Used to download the known WEIGHT already placed on the scale for Span factor computation.
Master transmission:
STX ADD b yyyyy BCS2 BCS1 ETX
yyyyy: 5 digits without decimal point (ASCII decimal)
Poll the slave with command ‘?’. Possible responses: “WAIT..” or “ERR 90” or “ERR 91”.
Slave returns to normal weight output mode after the command is completed.
THE VALUE IS NOT SAVED IN EEPROM UNTIL A STORE COMMAND IS ISSUED.
C. DOWNLOAD mV/V OF EACH CORNER
Used to download mV/V output at rated capacity of each loadcell. The loadcells must be of the
same rated capacity. The FAD-4 will expect the data for the number of loadcells stated in P1
command.
Master transmission:
STX ADD C 1 yyyyyy BCS2 BCS1 ETX
yyyyyy : 6 digits (ASCII decimal) of rated mV/V multiplied by 10000 for CORNER 1.
Poll the slave by using command ‘?’. Possible response messages: “ERR 91” or “CORN.2”
Master transmission:
STX ADD C 2 yyyyyy BCS2 BCS1 ETX
yyyyyy : 6 digits (ASCII decimal) of rated mV/V multiplied by 10000 for CORNER 2.
