Fault Codes
n : A sum of some of the following numbers when the faults are
present.
n =
0 : No faults reported , (transmitted when last fault
clears, or on request with the 'F?' identifier if no
faults are present).
n =
1 : Balance fault - CONTACT SUPPLIER.
n =
2 : FAULT 08
n =
4 : FAULT 09
n =
8 : Reserved for future development.
n =
16 : WARNING 02
n =
32 : WARNING 03
n =
64 : WARNING 04
n =
128 : EPROM checksum fault.
n =
256 : Reject Confirmation, Reject error.
n =
512 : Reject Confirmation, Input/Output error.
n =
1024 : Data collection unit not ready.
n =
2048 : Data Collection unit not configured.
n =
4096 : WARNING 07
n =
8192 : Balancing - please wait.
n = 16384 : Reserved for future development.
n = 32768 : One or possibly more extended-faults are present,
use the 'e?' command to ascertain which
extended-faults are present.
Current fault status ?
Inverse detect
m = product number, a two digit number in the range [0..20]
n = 0 : NO
n = 1 : YES
Inverse detect (for product number m) ?
Message Length
The number of characters, (or bytes), from after 'G'n to (but
excluding) ETX in every communications message.
n = A two digit number with leading zeroes, in the range [0..99].
For example, the host transmission of the 'a?' command.
The message format, (assuming XXXX = 4 digit message
number), would be :-
(STX)G07MXXXXa?(ETX)(CRC)
where:
G is the message length identifier, and where
n=07 is the total number of characters in the 'MXXXXa?' part
of the message.
Bargraph and detection comms switch
n = 0 : Disable the 'A'n and 'R'n identifiers from automatic
transmission
n = 1 : Enable the 'A'n and 'R'n identifiers for automatic
transmission
Bargraph Comms switch ?
Speed setting.
n = 0 : NORMAL speed
n = 1 : VARIABLE speed
n = 2 : FAST speed
n = 3 : Reserved for future development
Speed setting ?
