3.1 Troubleshooting
3.1.1 Error Message Codes
The following error messages are displayed to aid the user in troubleshooting the system. Many of the
error messages relate to data stored in the non-volatile memory. Error messages 11, 12, 13, and 16 can
be investigated by the user. Consult factory for all other failures.
Symptom
Problem
Solution
Error Message 1 (ER1)
Relay 1: Error in stored data
Consult factory.
Error Message 2 (ER2)
Relay 2: Error in stored data
Consult factory.
Error Message 3 (ER3)
Relay 3: Error in stored data
Consult factory.
Error Message 4 (ER4)
Relay 4: Error in stored data
Consult factory.
Error Message 5 (ER5)
Relay configuration: lead-lag, Fail-safe
Consult factory.
Error Message 6 (ER6)
Average/filtering
Consult factory.
Error Message 7 (ER7)
Probe Hi/Probe Lo calibration error
Consult factory.
Error Message 8 (ER8)
Computation error based on E7
Consult factory.
Error Message 9 (ER9)
Parameter error in power up
Consult factory.
Error Message 10 (ER10)
Not applicable
Not Applicable.
Error Message 11 (ER11)
Preamplifier Test
Integral: consult factory.
Remote: measure current on the positive
(+) side of circuit, between preamplifier and
main amplifier; 30 to 40 mA is proper.
Error Message 12 (ER12)
Probe Short Test
Disconnect the probe wire from the probe.
Measure the resistance between the probe
connection screw and the metal probe
mounting nut; use the highest resistance
scale available. A reading of 10 megohm
or greater (and stable) is proper.
NOTE: If the application is an insulated probe in
a conductive medium, it helps to have the process
level at the highest point possible. This aids in
checking for nick or cuts in the probe insulation.
Error Message 13 (ER13)
Open probe circuit
Check wiring between electronics and
probe.
Error Message 16 (ER16)
Immeasurable signal – No wave form
beyond maximum capacitance
capability.
Integral: Consult factory.
Remote: Perform checks described
under Error Messages 11, 12, and 13.

No fail-safe choice offered for RLY 3
Numbers have exceeded lower limit of
negative 999, usually caused by PRLO/
PRHI points being entered extremely
close to (or on top of) one another.
Numbers have exceeded upper limit of
19,999, usually caused by PRLO/
PRHI points being entered extremely
close to (or on top of) one another.
LEAD is chosen in Mode/Control,
yielding a lead-lag function.
Recalibrate PRLO/PRHI points.
Recalibrate PRLO/PRHI points.
This is a normal condition for the lead-lag
