Diagnostic board voltage
error codes
50
Diagnostic voltages are read by the instrument every second and any out of
tolerance results are sent to the Fault Manager. If any voltage failure occurs, it
will be reported in the following ways:
An error message is written on the front panel LCD in the STATUS: FAULTS
display with the code "0xmn" listed in the box representing the error code as
shown below. The letter "m" represents the board number and "n" represents
the index on that board. In the case of board 0, the leading 0 is truncated.
A similar message, which includes the event code, is entered in the Event Log.
If the user-configurable event reporting methods (SNMP trap, e-mail, GPI
signal, instrument beeper) are enabled to notify in the event of a voltage error,
then a message is sent using the enabled method(s).
Event codes. The event code consists of two numbers, where the first number
represents the board and the second number represents the voltage index of the
board. The Main board number is 0 and the module board numbers are 1 to 4.
Depending on the configuration of your instrument, only some of the modules
may be installed. The relationship between the module number and the channel
numbers of an instrument are as follows:

The modules can be either REF/ELSW or HREF/Relay boards. The REF boards
do not have the +3.1RL voltage. The index number is the same for all module
types. The following table lists the possible code combinations.
