3.5. UNIT PRE-TRIP DIAGNOSTICS

Pre--Trip Diagnostics is an independent controller

function which will suspend normal refrigeration

controller activities and provide preprogrammed test

routines. The test routines include Auto Mode testing,

which automatically preforms a pre programmed

sequenced of tests, or Manual Mode testing, which

allows the operator to select and run any of the

individual tests.

CAUTION

Pre-trip inspection should not be per-

formed with critical temperature cargoes in

the container.

CAUTION

When Pre-Trip key is pressed, economy, de-

humidification and bulb mode will be deac-

tivated. At the completion of Pre-Trip activi-

ty, economy, dehumidification and bulb

mode must be reactivated.

Testing may be initiated by use of the Key Pad or via

communication, but when initiated by communication

the controller will execute the entire battery of tests

(auto mode).
At the end of a pre-trip test, the message “P,” “rSLts”

(pretest results) will be displayed. Pressing the ENTER

key will allow the user to see the results for all subtests.

The results will be displayed as “PASS” or “FAIL” for all

the tests run to completion.
A detailed description of the pre-trip tests and test codes

is provided in Table 3-7, page 3-20. detailed operating

instructions are provided in paragraph 4.8.

Power supply (battery pack).

The DataCORDER performs the following functions:
a. Logs data at 15, 30, 60 or 120 minute intervals and

stores two years’ of data (based on one hour interval).

b. Records and displays alarms on the display module.
c. Records results of pre--trip testing.

3.6.2 DataCORDER Software

The DataCORDER Software is subdivided into the

Configuration Software, Operational Software and the

Data Memory.

a. Operational Software

The Operational Software reads and interprets inputs

for use by the Configuration Software. The inputs are

labeled Function Codes. There are 35 functions (see

Table 3-8, page 3-24) which the operator may access to

examine the current input data or stored data. To access

these codes, do the following:

1 Press the ALT. MODE & CODE SELECT keys.
