AL62
O
2
OUT OF RANGE
Cause:
This is a notification alarm and does not pose a risk to fresh produce. AL62 is triggered when there
is an indication that the O
2
level is rising after reaching its setpoint (+ 1%). If O
2
level exceeds 4%
above setpoint, the alarm is activated. The alarm does not activate if the unit was pre-tripped or trip
started between last reaching its O
2
setpoint and exceeding the plus 4%, or if power has been
turned off for eight hours. The alarm is deactivated if O
2
drops below setpoint (+ 1%) or if a pre-trip
or trip start is performed.
Component

Component
Container Air Tightness
Troubleshooting

hardware, etc).
AL96
SCRUBBER ROTATIONAL FAILURE - OPTIONAL FEATURE
Cause:
Feedback from the Scrubber Motor to the controller is not sensed when the motor is turning.
Component
Scrubber Fuse
Troubleshooting
Check to see if Scrubber Fuse is blown. Replace Fuse if necessary.
Component
Scrubber Motor
Troubleshooting
Run Test Mode and verify scrubber bed is turning. If back panel cannot
be removed to check, verify the scrubber amperage consumption, read
at XS contactor wire XSL1. If between 40 and 200mA, motor is rotating
properly. If no current detected, check and replace FX3. If current spiking
to 350mA for 2 seconds then dropping to 90mA, the scrubber motor is lo-
cated. If scrubber motor is locked, further inspection of the scrubber bed
is required. Unit will control CO
2
with the fresh air solenoid when this
alarm occurs if scrubber inaccessible.
If Scrubber Motor not operating, follow the troubleshooting flowchart in
and take appropriate action.
Component
Ground Interface Module (GIM)
Troubleshooting
Once it has been verified that the scrubber motor is rotating check the
wiring connections to the GIM module. If all wires secured properly, re-
place the GIM module if one is available. If not, the unit will control CO
2
using the fresh air solenoids.
