4.4.3 Diagnostic Messages

The UDC3200 performs background tests to verify data and memory integrity. If there is a malfunction, a diagnostic message will be shown on the lower display. In the case of more than one simultaneous malfunction, only the highest priority diagnostic message will be displayed. Table 4-4shows the error messages in order by priority.

Table 4-4 Diagnostic Messages

Description

Unable to write to nonvolatile memory. A subsequent successful write to nonvolatile memory removes this message.

This error message appears whenever the controller goes into a failsafe mode of operation. Failsafe operation occurs when an analog input fails or when configuration is corrupted.

Two consecutive failures of input 1 integration or input value is outside of Out-of-Range limits.

Two consecutive failures of input 2 integration or input value is outside of Out-of-Range limits.

Slidewire input failure. Position Proportional Control automatically switched to Three Position Step Control.

Configuration Errors—Low limit greater than high limit for PV, SP, Reset, or Output.

Carbon Potential Problem—Percent Carbon outside of “sooting boundary.”

Input 1 Out-of-Range—Input is outside of the High or Low Limits. Out-of-range criteria:

Linear range: ± 10 %

Characterized range: ± 1 %

Input 2 Out-of-Range—Same criteria as Input 1.

PV beyond limits—PV outside of PV Hi/Low Limits. PV = (PV source x PV source ratio) + PV source bias

Failsafe—Check inputs or configuration.

Remote Variable beyond limits—RSP outside of SP Hi/Low Limits. RV = (RV source x RV source ratio) + RV source bias

Segment Error—SP Program starting segment number is less than ending segment number.

Slidewire not calibrated. Perform Slidewire calibration. Position Proportional slidewire input failure.

The Thermocouple on Input 1 is starting to burnout.

The Thermocouple on Input 2 is starting to burnout.

Thermocouple on Input 1 is in imminent danger of burning out.

Thermocouple on Input 2 is in imminent danger of burning out.

Current Output is less than 3.5 mA.

Current Output 2 is less than 3.5 mA.
