11.11 Transmitter Leds - Emerson Micro Motion 2400S Configuration And Use Manual

Troubleshooting
If simulation mode is active, the simulated values are stored in the same memory locations used for
process data from the sensor. Therefore, the simulated values will be used throughout transmitter
functioning. For example, simulation will affect:
• All mass flow, temperature, or density values shown on the display or reported via digital
communications
• The mass total and inventory values
• All volume calculations and data, including reported values, volume total, and volume
inventory
• All related values logged by Data Logger (a ProLink II utility)
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.
Simulation does not change any diagnostic values.
Simulation mode is available only via ProLink II. To set up simulation, refer to Figure B-3 and follow
the steps below.
1. Enable simulation mode.
2. For mass flow:
a. Specify the type of simulation you want: fixed value, sawtooth (triangular wave), or sine
wave.
b. Enter the required values.
• If you specified fixed value simulation, enter a fixed value.
• If you specified sawtooth or sine wave simulation, enter a minimum value, maximum
value, and wave period. Minimum and maximum values are entered in the current
measurement units; the wave period is entered in seconds.
3. Repeat Step 2 for temperature and density.
To use simulation mode for problem location, enable simulation mode and check the signal at various
points between the transmitter and the receiving device.
Be sure to disable simulation when testing is complete.

11.11 Transmitter LEDs

The user interface board includes three LEDs:
• A status LED. See Table 7-5 for information on status LED behavior. If the status LED
indicates an alarm condition:
a. View the alarm code using the procedures described in Section 7.5.
b. Identify the alarm (see Section 11.12).
c. Correct the condition.
d. If desired, acknowledge the alarm using the procedures described in Section 7.6.
• A module LED. See Table 7-3 for information on the behavior of the module LED and
suggestions on user response.
• A network LED. See Table 7-4 for information on the behavior of the network LED. The
network LED indicates the state of the device on the network, and does not indicate device
status. Troubleshooting should focus on the network rather than the device.
