Error Numbers
The table below lists all ADC error numbers, together with likely causes and suggested remedies. The error numbers
apply both to errors appearing on the display and to error messages sent over the RS232 link.
Table A1 - ADC error numbers
ERR
number
Meaning
Possible cause / remedy
Controller errors
0
No error
RS232 message in response to a correctly formatted
command, indicating no error.
1
EEPROM error
The internal EEPROM checksum has failed. Some stored
values such as set-point thresholds will revert to the factory
default.
2
ID reference error
The reference used for identifying gauges is incorrect. Please
remove all gauge connection, turn the electrical supply off
and on, and wait for 30 seconds before connecting gauges.
Gauge errors
11
Gauge voltage too high
The voltage from a gauge is too high. The gauge may be
defective.
12
Gauge voltage too low
The voltage from a gauge is too low. The gauge may be
defective.
13
AIM Gauge not striking
The voltage from a gauge is too low. The gauge may be
defective.

WRG magnetron short
23
WRG striker fail
24
WRG magnetron not struck
25
APGX filament failure
Errors specific to APGX. Please refer to the APGX manual for
details.
26

RS232 errors
51
Not a valid query or command word
The ADC did not recognise the mnemonic in a message.
Check that the message is as specified in
and
52
Message incomplete
The mnemonic was recognised but additional characters
were expected. Check that a command (!) was not used in
place of a query (?).
53
Message too long
The mnemonic was recognised by had extra characters at
end of message. Check format of command message in
.
54
Incorrect gauge number
Queries and commands are only valid for gauges 1 and 2.
57
Incorrect number format
A command had an invalid number. Check range of valid
numbers in
