data regarding the TUNE will be lost, so it will be necessary to
re-start the SMART function.
If a power down occurs during the second part of SMART
algorithm (ADAPTIVE), at the next power up, the instrument
restarts the ADAPTIVE function.

CONTROL ACTION FEATURE

CONTROL ACTION FEATURE
The control action is de-activated (control output forced to 0)
and alarms forced in no alarm condition when:
a) The setpoint is set at minimum value (0.00 for CP/0 for mV/-
100°F (-75°C) for Dew Point/0.0 for O2)
b) The remote set point( if selected) is out of range and “

A.I.Añ = norñ.”

c) The probe output is lower than 900 mV or greater than 1300
mV and “Carbon potential or “Dew Point” are configured as
primary control variable.
When “O2” is configured as primary control variable the probe
mV limits are -15 / 200 mV
d) The probe temperature is lower than 900 °F (482 °C) or
greater than 2100 °F (1149 °C) and “Carbon potential or Dew
Point” are configured as primary control variable.
When “O2” is configured as primary control variable the
temperature limits are 1200 /2900 °F (650/1590 °C)

N o t e : When conditions c) or d) occur (independently from
primary control variable selection), the
Carbon potential, Dew Point and O2 are not calculated but
forced respectively to 0.00 ,250 °F (121 °C) or 0.0
