Diagnostics and Troubleshooting
If sensor simulation mode is active, the specified simulated values are substituted for process data
from the sensor. Therefore, sensor simulation will affect, for example:
• All mass flow, temperature, or density values shown on the display or reported via outputs or
digital communications
• The mass total and mass inventory values
• All volume calculations and data, including reported values, volume totals, and volume
inventories
Accordingly, do not enable simulation when your process cannot tolerate these effects, and be sure to
disable simulation when you have finished testing.
Note: Unlike actual mass flow and density values, the simulated values are not
temperature-compensated.
Note: Simulation does not change any diagnostic values.
Sensor simulation mode is available via ProLink II (see Figure G-3) or the Communicator (see
Figure H-7). To set up sensor simulation, follow the steps below:
1. Enable simulation mode.
2. For mass flow:
a. Specify the type of simulation you want: fixed value, triangular wave, or sine wave.
b. Enter the required values.
• If you specified fixed value simulation, enter a fixed value.
• If you specified triangular wave or sine wave simulation, enter a minimum amplitude,
maximum amplitude, and period.
3. Repeat Step 2 for temperature and density.
To use sensor simulation mode for problem location, enable simulation mode and check the signal at
various points between the transmitter and the receiving device.
22.5 Updates, upgrades, and master resets
Micro Motion recommends that you document or save device configuration information before
updating or upgrading the software in your Series 3000 device or before performing a master reset.
You can document the configuration manually. Alternatively, if you have ProLink II, you can save the
configuration data to a file on the PC.
22.6 Alarm types and handling
The Series 3000 device performs self-diagnostics during operation. If the device detects certain events
or conditions, an alarm message appears in the highlight bar at the top of the screen, and an alarm is
written to the active alarm log.
22.6.1 Alarm severity
Alarms are classified into three levels of severity. The severity level controls device behavior when the
alarm condition occurs. See Table 22-3.
