• Enhanced battery charging, this will shorten 
the time required to charge the battery for

Software Card
The ML3 controller will require a new type of 
programming card.  The new type is referred to as a
PCMCIA card.  Although there are many versions of
cards available throughout the world, Carrier Transicold
has selected one that fits its application and is guaran-
teed to work properly.  The new card part number is 
12-00594-XX.  Carrier Transicold only supports the use
of this card.
This card can hold the configuration and operation 
software for all 5XX...

To program Operational Software into the
controller:
1. Turn Power off 
2. Insert software/programming PCMCIA card 
containing the following (example) files:
•menuDDMM.ml3, this file allows the user 
to chose which file/program to upload into 
the controller.
•cfYYMMDD.ml3, multi-configuration file  
•recp51XX.ml3, controller software program 
for recip units.
•scrl53XX.ml3, controller software program 
for scroll units.

High Pressure Switch 
In December 2003, Carrier Transicold began factory
installing a new High Pressure Switch with an internal
snubber, P/N 12-00309-06, on all Container 
69NT40-511 (non-Scroll) units. The new switch
supercedes the old style switch, P/N 12-00309-03
which required the use of a separate snubber elbow.  
The new switch can be used on all non-Scroll units
equipped with an OEM High Pressure Switch. When
installing the new style switch in a unit that currently
has the old style...

Auto Defrost
Starting with software revisions 5127 (Recip Units),
Carrier Transicold introduced the Auto Defrost user
selectable option.   This option is an optimal way to
ensure proper airflow and lower power consumption.
The option has been added to the Defrost Interval selec-
tion (code select 27).   When scrolling through the
selection you will now have the following options, 3, 6,
9, 12, 24 and the new option AUTO  (some units may
be configured to allow defrost to be disabled altogether;...

Selection of Oil Filter
There is some confusion in the field regarding the cor-
rect oil filters to use in Carrier generator sets. In part,
this has come about with technological improvements
in the synthetic filter media.  The full flow and the
bypass options are now combined into the same filter
(detailed in the 4th Quarter 2003 TechLine).   Below
should assist in identifying the correct filter to be used
in the 69RG and 69UG units.
Units equipped with dual filter housings (oil bypass...
