Monitoring and Operating the Controller

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 4-4shows 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

EEFAIL 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.
