Parameter
Definition
NO BURNOUT—Pre-configured Failsafe output
(selected in the CONTROL or CONTROL2 Set up
Group) applied if failed input is detected (does not
apply for an input out of range). Diagnostic message
IN2 FAIL is intermittently flashed on the lower
display.
UPSCALE BURNOUT—Forces the Input 2 signal to
the full-scale value when the sensor fails. Diagnostic
message IN2 FAIL intermittently flashed on the lower
display.
The controller remains in Automatic control mode
and adjusts the controller output signal in response
to the full scale Input 2 signal developed by the
Burnout circuitry.
DOWNSCALE BURNOUT—Forces the Input 2
signal to the lower range value when the sensor
fails. Diagnostic message IN2 FAIL intermittently
flashed on the lower display.
The controller remains in Automatic control mode
and adjusts the controller output signal in response
to the lower range Input 2 signal developed by the
Burnout circuitry.
NO FAILSAFE—This selection does not provide
input failure detection and should only be used when
a thermocouple input is connected to another
instrument that supplies the Burnout current. (For
this selection, no burnout signal is sent to the
sensor.)
ATTENTION The Thermocouple Health feature is
disabled when NO FS is configured.
EMISSIVITY—A correction factor applied to the
Radiamatic input signal that is the ratio of the actual
energy emitted from the target to the energy that
would be emitted if the target were a perfect radiator.
Available only for Radiamatic inputs.
