surement within the Failsafe Timer
period. Possible causes: faulty
installation, antenna buildup, foam-
ing/other adverse process condi-
tions, invalid calibration range.
S: 2 * The device is operating in a low
power condition that is outside its
operating range. As a result, a valid
measurement has not been taken
for the failsafe timer period, and the
device will be put into failsafe mode.
