Software diagnostics
The density transmitter system can alert users to potential problems by:
• Posting messages on the Ohmview 2000 message screen
• Energizing the output relay
• Distinctly changing the current loop output
• Tracking the current status and history in the Gauge status screens
Table 5.1 Alarm types
Name Description
Diagnostic
alarm
Provides information about the density gauge system and alerts
users when periodic procedures are due.
Analog alarm Sets the current loop mA output to 2 mA or 22 mA when the detector
outputs 0 counts.
Process
alarm
The process alarm lets the relay output trip when the process density
is above (high limit) or below (low limit) a setpoint.
X-ray alarm Distinctly changes the current loop mA output in response to a
marked increase in the radiation field. This prevents control
problems when external radiographic sources are in the area for
vessel inspections.
