4.5.3 Diagnostic Messages

The UDC2500 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 4-4 shows the error messages in order by priority. If any of these
diagnostic messages appear on the lower display, refer to

Section 7 - Troubleshooting

for

information on how to correct the problem.

Table 4-4 Diagnostic Messages

Prompt

Description

EE FAIL

Unable to write to non-volatile memory.

IN1FL

Two consecutive failures of input 1 integration.

IN2FL

Two consecutive failures of input 2 integration.

CFGERR

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

IN1RNG

Input 1 Out-of-Range
Out-of-range

criteria:

Linear range: ± 10 % out-of-range

Characterized range: ± 1 % out-of-range

IN2RNG

Input 2 Out-of-Range—Same as Input 1.

PV LIM

PV Out-of-Range
PV = (PV source x PV source ratio) + PV source bias

FAILSF

Failsafe — conditions for failsafe are:

… EEROM Test Failed

… Scratch Pad RAM Test Failed

… Configuration Test Failed

… Field or Factory Cal Test Failed

Check the “Status” group.

RV LIM

Remote Variable Out-of-Range
RV = (RV source x RV source ratio) + RV source bias

SEG ERR

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

LOCK

The lockout feature has been enabled to prevent unauthorized changes of
certain functions or parameters.

TCWARN

Thermocouple sensor is starting to burnout.*

TCFAIL

Thermocouple sensor is in imminent danger of burning out.*

OUT1 FL

Current Output 1 is less than 3.5 mA.**

OUT2 FL

Current Output 2 is less than 3.5 mA.**

*

The Thermocouple Error messages can be disabled via the TCDIAG configuration in the DISPLAY setup group.

** The Current Output Error messages can be disabled via the DIAGAL configuration in the ALARM setup group.
