FILTER 1
0 to 120 seconds
No filter = 0
FILTER FOR INPUT 1—A software digital filter is
provided for Input 1 to smooth the input signal. You
can configure the first order lag time constant from 1
to 120 seconds. If you do not want filtering, enter 0.
BURNOUT
BURNOUT PROTECTION (SENSOR BREAK)
provides most input types with upscale or downscale
protection if the input fails.
NONE
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.
UP
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.
DOWN
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 FS
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.
