Diagnostic codes

When an alarm condition is triggered in the transmitter, an indicator displays on the HMI LCD (Figure 48).
The following procedure will determine the diagnostic code for the alarm, possible causes, and available corrective action(s).
1. Press the left soft key to access the Operator Menu > Diagnostics (Figure 49).
2. The alarm and diagnostic code are shown in the window (Figure 50).
3. Press the right soft key (Exit) to return to the main display.
IMPORTANT NOTES: Alarm conditions, if any, display one at a time. If multiple alarms exist in the transmitter,
each condition must be cleared before the next alarm may be viewed.
Diagnostic flags are updated once per second.
4. Lookup the diagnostic code in Table 16 to determine the possible cause(s) and recommended actions to aid in clearing the
alarm and take the recommended action.
