Troubleshooting; Error Messages; Diagnostics - Honeywell SmartLine SLG 700 User Manual

All troubleshooting should be performed by trained and qualified personnel.
Troubleshooting of hardware failures should be performed by replacement of corresponding
modules. Measurement troubleshooting should be performed based on reference
measurements and internal diagnostics. The following components may be replaced for
troubleshooting in the field:
 Probe and / or end weight
 Centering disk
 Process connector
 Locking elements for probe mounting, for example, nuts, lock washers and set screws.
 Display module
 Terminal module
 Communication module

6.1 Error Messages

Self-explanatory error descriptions (not only error code) in an end user selected language can
be accessed using the local display, handheld device, or provided software tools (DD, DTM).

Diagnostics

When a Critical Diagnostic is present in the Transmitter, the Advanced Display will show a
screen with heading "Critical Diag" and beneath it a description of the condition. These
screens will be inserted into the normal screen rotation and displayed between the user-
defined operator screens.
The standard diagnostics are reported in the two basic categories listed in Table 6-1.
Problems detected as critical diagnostics drive the analog output to the programmed burnout
level for HART protocols only.
Problems detected as non-critical diagnostics may affect performance without driving the
analog output to the programmed burnout level. Informational messages (not listed in
Table 6-1) report various Transmitter status or setting conditions.
The messages listed in Table 6-1 are specific to the Transmitter, exclusive of those associated
with the HART protocol. HART diagnostic messages and additional diagnostic capabilities
are listed and described in the SLG 700 SmartLine HART Option User Manual, Document
#34-SL-25-06.
