6. MAINTENANCE
6.5 Integral Indicator and Error
Display
For temperature transmitters equipped with an integral
indicator, errors in the temperature sensor or the
transmitter cause an integral indicator to call up the
applicable error code. Table 6.4 lists the error codes
and the associated corrective actions.

Input value is lower than the
PV low range value.
Input value is higher than the
PV upper range value.
Sensor1 fails or disconnects
from the terminal block.
Sensor2 fails or disconnects
from the terminal block.
Sensor1 input value greatly
exceeds the sensor
measurement range. Sensor
type setting or connection
polarity may be incorrect.
Sensor2 input value greatly
exceeds sensor
measurement range. Sensor
type setting or connection
polarity may be incorrect.
The ambient temperature
exceeds the lower ambient
temp limit and the specified
accuracy cannot be
achieved.
The ambient temperature
exceeds the upper ambient
temp limit and the specified
accuracy cannot be
achieved.
Sensor backup mode is in
effect.
There is a problem with the
PV mapping settings.
Terminal block temperature
sensor failed.
EEPROM failed.
Output side hardware failure.
Input circuit hardware failure.
Output goes to minimum
value(–2.0%).
Output goes to maximum
value(105%).
If sensor1 is set as PV, the
burnout value is output.
When sensor backup mode
is set in YTA320, sensor2
input is used as output.
If sensor2 is set as PV, or
sensor backup mode is in
effect, sensor burnout value
is output.
Output goes to minimum
value(–2.0%) or maximum
value(105%).
Output goes to minimum
value(–2.0%) or maximum
value(105%).
Continues to operate and
output.
Continues to operate and
output.
Sensor2 input is used as
output. If sensor2 also fails,
the transmitter operate with
burnout settings.
Output status immediately
before error is retained
(HOLD).
Operation and output
continues.
The output goes to the
value set by the hardware
failure mode jumper.
The output goes to the
value set by the hardware
failure mode jumper.
The output goes to the
value set by the hardware
failure mode jumper.
Check the LRV setting and
adjust.
Check the URV setting and
adjust.
•Check sensor for damage.
•Check terminal connection.
• If sensor backup mode is set,
refer to “Er-09”.
•Check sensor for damage.
•Check terminal connection.
• If sensor backup mode is set,
repair wiring or replace
damaged sensors.
•Check sensor connections.
•Check the sensor type
selected.
•Check sensor connections.
•Check sensor type selected
.
Use a heater to raise the
ambient temperature, or reset to
a higher level.
Take enough distance from the
source of heat, or reset to a
lower level.
Restore the status of sensor1 to
normal and Enable sensor1
return parameters, or turn the
power ON again.
Check the setting for PV
mapping and correct the setting.
