Diagnostic error messages

The UDC 3300 performs background tests to verify data and memory integrity. If there is a malfunction, an error message will be displayed. In the case of more than one simultaneous malfunction, only the one with the highest priority will appear on the lower display.

A list of error messages is contained in Table 5-5. If any of these error messages occur, refer to Section 9 - Troubleshooting for information to correct the failure.

Table 5-5 Error Messages

Description

Unable to write to nonvolatile memory.

Two consecutive failures of input 1 integration.

Two consecutive failures of input 2 integration.

Two consecutive failures of input 3 integration.

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

Configuration Errors for Loop 1— Low limit greater than high limit for PV, SP, Reset, or Output.

Configuration Errors for Loop 2— Low limit greater than high limit for PV, SP, Reset, or Output, or Loop 2 output has not been selected.

Input Combination Errors— Percent Carbon falls outside of “sooting boundary.”

Input 1 Out-of-Range Out-of-range criteria:

Linear range: ± 10 % out-of-range

Characterized range: ± 1 % out-of-range

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

Input 3 Out-of-Range— Same as Input 1.

PV Out-of-Range

PV = (PV source x PV source ratio) + PV source bias

Failsafe Loop 1— Check inputs or configuration.

Failsafe Loop 2— Check inputs or configuration.

Remote Variable Out-of-Range

RV = (RV source x RV source ratio) + RV source bias

RH Excessive Temperature Depression— Calculated % RH is less than 0 %.

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

Not calibrated. Perform Position Proportional calibration.
