PreTrip Initiated:
Configuration
Display, Indicator
Lamps, LEDs, and
Displays
Container identifier code, Cd18 Software Revision Number, Cd20 Container Unit
Model Number, & configuration database identifier CFMMYYDD are displayed in
sequence.
Next the unit will indicate the presence or non-presence of an RMU according to
whether any RMU inquiry messages have been received since the unit was booted.
Units equipped with Autoslide Enabled (Cnf44) will cause the vent to seek to its
closed position, followed by two sequences of opening to 100% and returning to
the closed position. No other Autoslide mode of operation will be available until the
two cycles of opening and closing have completed.
Since the system cannot recognize lights and display failures, there are no test
codes or results associated with this phase of Pretrip. To know if the test passes
the operator must observe that the LCD display elements and the indicator lights
behave as described below.
P1 Tests - Heaters Current Draw: Heater is turned on, then off. Current draw must fall within specified range.
No other system components will change state during this test.
P1-0 Heaters On Test
Heater starts in the off condition, current draw is measured, and then the heater is
turned on. After 15 seconds, the current draw is measured again. The change in
current draw is then recorded.
Test passes if the change in current draw test is in the range specified.
P1-1 Heaters Off Test
Heater is then turned off. After 10 seconds the current draw is measured. The
change in current draw is then recorded.
Test passes if change in current draw is in the range specified.
P2 Tests - Condenser Fan Current Draw: Condenser fan is turned on, then off. Current draw must fall within
specified range. No other system components will change state during this test.
P2-0
Condenser Fan On
Test
Condenser fan starts in the off condition, current draw is measured, and con dens-
er fan is then turned on. After 15 seconds the current draw is measured again. The
change in current draw is then recorded.
Test passes if change in current draw test is in the specified range.
P2-1
Condenser Fan Off
Test
Condenser fan is then turned off. After 10 seconds the current draw is measured.
The change in current draw is then recorded.
Test passes if change in current draw test is in the specified range.
P3 Tests - Low Speed Evaporator Fan Current Draw: The system must be equipped with a low speed evapo-
rator fan, as determined by CnF02, the Evaporator Fan Speed Select configuration variable. Low speed evapo-
rator fan is turned on, then off. Current draw must fall within specified range. No other system components will
change state during this test.
NOTE
If unit configured for single evaporator fan operation and either AL11 or AL12 is active at the start of
either test, then the test will fail immediately. If AL11 or AL12 become active during the test, then the
test will fail upon conclusion of the test.
P3-0
Low Speed
Evaporator Fans On
Test
High speed evaporator fans will be turned on for 20 seconds, the fans will be
turned off for 4 seconds, current draw is measured, and then the low speed evap-
orator fans are turned on. After 60 seconds the current draw is measured again.
The change in current draw is then recorded.
Test passes if change in current draw test is in the specified range.
P3-1
Low Speed
Evaporator Fan Off
Test Low speed evaporator fans are then turned off. After 10 seconds the current draw
is measured. The change in current draw is then recorded.
Test passes if change in current draw test is in the specified range.
