Error Messages
Overrange or underrange indication
The instrument shows the OVERRANGE and
UNDERRANGE conditions with the following indications:
Overrange
Underrange
The sensor break can be signaled as:
- For TC input: OVERRANGE or UNDERRANGE
selected by a solder jumper
- For RTD input: OVERRANGE
On the RTD input, a special test is provided to signal an
OVERRANGE when input resistance is less than 15
Ohms (short circuit sensor detection).
Output action on overrange/underrange
When:
-
The instrument is set for one output only and an
OVERRANGE is detected, OUT 1 turns OFF (if
reverse acting) or ON (if direct acting).
-
The instrument is set for heating/cooling and an
OVERRANGE is detected, OUT 1 turns OFF and OUT
2 turns ON.
-
The instrument is set for one output only and an
UNDERRANGE is detected, OUT 1 turns ON (if
reverse acting) or OFF (if direct acting).
-
The instrument is set for heating/cooling and an
UNDERRANGE is detected, OUT 1 turns ON and
OUT 2 turns OFF.
Error list
100
EEPROM write error.
150
CPU error.
200
Attempt to write to protected memory.
201 - 2xx
Configuration parameter error. The two
least significant digits show the number of
the wrong parameter (ex. 209 Err indicates
an Error in parameter P9).
301
RTD input calibration error.
305
TC input calibration error.
307
RJ input calibration error.
400
Control parameters error.
500
Auto-zero error.
502
RJ error.
510
General error during calibration procedure.
Dealing with error messages
1) When a configuration parameter error is detected,
repeat the configuration procedure of that specific
parameter.
2) If an error 400 is detected, simultaneously press the
▲
and
▼
keys (see Loading default operating
parameters) to load the default parameters and then
repeat the control parameter setup.
3) For all other errors, contact your Service
Representative.
