tESt - Sensor Tests
During a sensor test, the controller will verify that the CO
2
sensor is reading 0% and the O
2
sensor is in a
valid range. If both meet this requirement, a calibration test “CAL StArt” will be displayed for five seconds,
a CO
2
sensor calibration will be performed and an O
2
sensor validity check will be performed. Then, a ten
minute countdown timer is placed in the right hand display.
If both sensors pass, a “CAL PASS” message will display for five minutes or until the user presses and
holds the CODE SELECT key for five seconds. In either case, normal operation will be resumed.
If one or both of the sensors are outside of the range, check condition requirements. The failed results will
be displayed “No CAL”, alternating every five seconds. To exit, the user should press and hold the CODE
SELECT key for three seconds. A “CO
2
FAIL” or “O
2
FAIL” message will appear if the test fails.
If the range check fails (indicating a drifted sensor), verify that the box is clean of cargo remnants from last
trip, open the back doors, and rerun the test. If the range check fails a second time, replace the sensor that
is out of range.
If either of the sensors fail open or shorted, an Alarm 09 for O
2
sensor or Alarm 10 for CO
2
sensor will occur.
NOTICE
It is required that the calibration procedure only be performed during pre-trip or when the con-
tainer has been fully vented.

2
setpoint, CO
2
per-
centage, O
2
setpoint, O
2
percentage, and O
2
voltage.
For the CO
2
setpoint, the range is from 0 to 19% in 1% increments with a default setting
of 5%. For the O
2
setpoint, the range is from 3% to 21% in 1% increments with a default
setting of 10%.
