Parameter
Definition
UPSCALE BURNOUT will force 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 will force 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 which supplies the Burnout current. (For
this selection, no burnout signal is sent to the
sensor.)
ATTENTION For Burnout to function properly on a
0-20 mA input type (or a 0-5V type that uses a
dropping resistor), the dropping resistor must be
remotely located (across the transmitter terminals).
Otherwise, the input at the instrument terminals will
always be 0 mA (i.e., within the normal operating
range) when the 0-20 mA line is opened.
EMISSIVITY is a correction factor applied to the
Radiamatic input signal that is the ratio of the actual
energy emitted from the target to the energy which
would be emitted if the target were a perfect radiator.
Available only for Radiamatic inputs.
