BURNOUT PROTECTION (SENSOR BREAK) provides most input
types with upscale or downscale protection if the input fails.
NO BURNOUT—Pre-configured Failsafe output (selected in the
CONTROL Set up Group) applied if failed input is detected (does
not apply for an input out of range). Diagnostic message IN1 FAIL
is intermittently flashed on the lower display.
UPSCALE BURNOUT will force the Input 1 signal to the full scale
value when the sensor fails. Diagnostic message IN1 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 1 signal
developed by the Burnout circuitry.
DOWNSCALE BURNOUT will force the Input 1 signal to the lower
range value when the sensor fails. Diagnostic message IN1 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 1
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.
