30 Instrument powered down (PWRDNSUP) .......................................................................CWR
The instrument powered down diagnostic checks if the instrument lost power. The diagnostic
can be suppressed or enabled as follows:
SUPPRESS 1 Diagnostic error is suppressed.
ENABLE 0 Diagnostic error is enabled.
31 Instrument powered down Unacknowledged (PWRDNUAK) ....................................... – WR
The unacknowledged instrument powered down diagnostic indicates if the condition is or is
not acknowledged. The status can be read or acknowledged as follows:
YES 1 Diagnostic error is unacknowledged.
NO 0 Diagnostic error is acknowledged.
32 Instrument powered down Active (PWRDNACT)............................................................– – R
The instrument lost power. A time stamp indicating the time power was lost is entered in the
event queue.
YES 1 “INSTRUMENT POWERED DOWN” is active.
NO 0 Diagnostic error is not active.
33 Communications Port Mismatch Unacknowledged (COMPTUAK) .............................. – WR
The unacknowledged communications port mismatch diagnostic indicates if the condition is or
is not acknowledged. The status can be read or acknowledged as follows:
YES 1 Diagnostic error is unacknowledged.
NO 0 Diagnostic error is acknowledged.
34 Communications Port Mismatch Active (COMPTACT) ..................................................– – R
Mismatch occurs when an ICN module (2030N) is installed but no matching ICN block was
found in the user database. Matching includes slot numbers and the module address switch
setting, if not 'ANY' in the ICN block. The same mismatch occurs if an RS232 module (2033N)
or an RS485 module (2034N) is installed but no matching MSC block was found in the user
database, slot numbers do not match, or the block address information does not match unless
'ANY' is configured in the MSC block.
YES 1 “COMMUNICATIONS PORT MISMATCH” is active.
NO 0 Diagnostic error is not active.
35 Instrument Shutdown Fault Unacknowledged (SHUTDUAK)....................................... – WR
The unacknowledged instrument shutdown fault diagnostic indicates if the condition is or is not
acknowledged. The status can be read or acknowledged as follows:
YES 1 Diagnostic error is unacknowledged.
NO 0 Diagnostic error is acknowledged.
36 Instrument Shutdown Fault Active (SHUTDACT) ...........................................................– – R
When the instrument was last powered, an event occurred which caused it to shut down. It is
now locked in the DEFAULT state. The user should investigate the cause of the shutdown
and try running the instrument again, if desired, by writing ACK SHUTDOWN FAULT (value 1)
to the command attribute of the interface block. This acknowledges that the user has seen the
information relating to a previous shutdown fault and reinitializes the SHUTDOWN INFO area.
Until this is done, the instrument will not accept commands which could cause it to leave the
DEFAULT state. Information preserved at shutdown is stored in the non checksummed save
