3. Press the alarm key to get the list of unacknowledged and active
acknowledged alarms and diagnostics (Appendix A lists all reportable
diagnostics and events). Press the key labeled UAK to acknowlege the
alarm (changes to ACT). Press the alarm key again to view the next
alarm and repeat until the end where you can return to the device display
(see Alarms in Section 3.13).
4. If a previous shutdown condition exists, it must be acknowledged from the device status
shutdown displays (Step 1B of Device Status Table 1); otherwise, template configuration
and memory module downloads will fail.
2.2 DEVICE STATES
The instrument state is indicated by a three letter code on line 3 of the device displays.
Except for Local Hold, installation of a template will change the instrument state to Run.
DEF
The Default state means the instrument has no valid user database and is running an
internal database to maintain communications and system activities.
HLD
The Hold state indicates the instrument has a valid user database and is performing
overhead functions only - no loops are running.
LHD
The Local Hold state indicates the SCRV/RUN switch is in SCRV and the instrument
is in the Local Hold state.
RUN
The Run state means the instrument has a valid user database and is running that
database.
2.3 USING THE MEMORY MODULE
The backup memory module is used to maintain a mirror image of the 64K instrument
database. A small part of this image is reserved for shutdown information and serves as a
valuable diagnostic tool. The module may be write protected to protect shutdown and other
information.
2.3.1 DOWNLOAD From Memory Module to Main Database
Follow this procedure to load a database stored in a memory module.
1. Set Memory Module switches to "read/write" or "Read Only" and "Normal".
2. Power up the instrument.
The instrument automatically attempts a download from the memory module during
power-up. If the module database is 'good' (configured, version compatible, has valid
checksums, no ICN or comm port mismatch), the 'download on warm start' attribute is
YES and the instrument did not have a previous shutdown fault, the transfer will occur.
The download on warm start attribute allows a user to (for instance) write protect a
module with cold start values in it and have it download only on cold start.
