4.5 STARTING AND STOPPING INSTRUCTIONS
WARNING
Make sur e that the unit circuit breaker(s)
(CB-1 & CB-2) and the START-STOP
switch(ST)arei nthe“O”(OFF)positionb e-
fore connecting to any electrical power
source.
4.5.1 Starting the Unit
1. Withpowerproperlyapplied,thefreshairdamperset
and (if required) the water cooled condenser con-
nected, (refer to paragraphs 4.2 & 4.3) place the
START-STOP switch to “I” (ON).
NOTE
Withinthefirst30secondstheelectronicphase
detection system will check for proper com-
pressor rotation. If rotation is not correct, t he
compressorwill bestopped andrestarted inthe
oppositedirection.Ifthecompressorisproduc-
ing unusually loud and continuous noise after
the first 30 seconds of operation, stop the unit
and investigate.
2. Continue with Start Up Inspection, paragraph 4.6.
4.5.2 Stopping the Unit
To stop the unit, place the START-STOP switch in
position “0” (OFF).
4.6 START--UP INSPECTION
4.6.1 Physical Inspection
a. Check rotation of condenser and evaporator fans.
b. Checkcompressoroillevel. (Refertoparagraph6.9.)
4.6.2 Check Controller Function Codes
Checkand, ifrequired, resetcontroller Function C odes
(Cd27 through Cd39) in accordance with desired
operating parameters. Refer to paragraph 3.2.2.
DataCORDER
a. Check and, if required, set the DataCORDER Con-
figuration in accordance with desired recording pa-
rameter. Refer to paragraph 3.6.3.
b. Enter a “Trip Start”. To enter a “trip Start”, do the
following:
1. Depress the ALT MODE key and scroll to Code
dC30.
2. Depress and hold the ENTER key for five seconds.
3. The “Trip Start” event will be entered in the Data-
CORDER.
4.6.3 Complete Inspection
Allow unit to run for 5 minutes to stabilize conditions
andperforma pre--tripdiagnosis inaccordancewiththe
following paragraph.
4.7 PRE-TRIP DIAGNOSIS
CAUTION
Pre-tripinspectionshouldnotbeperformed
with critical temperaturecargoes in thecon-
tainer.
CAUTION
When Pre-Trip key is pr essed, economy, de-
humidification and bulb mode will be deac-
tivated. AtthecompletionofPre-Tripactivi-
ty, economy, dehumidification and bulb
mode must be reactivated.
Pre-Trip diagnosis provides automatic testing of the
unit components using internal measurements and
comparison logic. The program will providea “PASS”
or “FAIL” display to indicate test results.
The testing begins with access to a pre-trip selection
menu. Theuser mayhave theoption ofselecting oneof
two automatic tests. These tests will automatically
perform a series of individual pre--trip tests. The user
may also scroll down to select any of the individual
tests.Whenonlytheshortsequenceisconfigureditwill
appear as “AUtO” in the display, otherwise “AUtO1”
will indicate the short sequence and “AUtO2” will
indicatethelongsequence. Thetestshortsequencewill
runtestsP0throughP6. Thelongtestsequencewillrun
tests P0 through P10.
Adetailed description of the pre-triptestcodesislisted
in Table 3-7, page 3-21. If no selection is made, the
pre-trip menu selection process will terminate
automatically. However, dehumidification and bulb
mode must be reactivated manually if required.
Scrolling down to the “rSLts” code and pressing
ENTER will allowthe userto scroll through theresults
ofthelastpre--triptestingrun.Ifnopre--testinghasbeen
run(oranindividualtesthasnotbeenrun)sincetheunit
was powered up “--------” will be displayed.
To start a pre--trip test, do the following:
NOTE
1. Priortostartingtests,verifythatunitvoltage
(Function Code Cd 07) is within tolerance
and unit amperage draw (Function Codes
Cd04, Cd05, Cd06) are within expected
limits. Otherwise, tests may fail i ncorrectly.
2. All alarms must be rectified and cleared
before starting tests.
