During DataCORDER power-up, while using battery-pack power, the controller will perform a hardware voltage
check on the battery. If the hardware check passes, the controller will energize and perform a software battery volt-
age check before DataCORDER logging. If either test fails, the real time clock battery power-up will be disabled
until the next AC power cycle. Further Data CORDER temperature logging will be prohibited until that time.
An alarm will be generated when the battery voltage transitions from good to bad indicating that the battery pack
needs recharging. If the alarm condition persists for more than 24 hours on continuous AC power, the battery pack
needs replacement.
4.7.9 Pre-trip Data Recording
The DataCORDER will record the initiation of a pre-trip test (refer to Section 4.6 ) and the results of each of the
tests included in pre-trip. The data is time-stamped and may be extracted via the Data Retrieval program. Refer to
Table 4–9 for a description of the data stored in the DataCORDER for each corresponding Pre-trip test.
4.7.10 DataCORDER Communications
Data retrieval from the DataCORDER can be accomplished by using one of the following: DataReader, DataLINE,
or a communications interface module.
NOTE
A DataReader, DataLINE or a communications interface module display of Communication Failed is
caused by faulty data transfer between the DataCORDER and the data retrieval device. Common
causes include:
1. Bad cable or connection between DataCORDER and data retrieval device.
2. PC communication port(s) unavailable or mis-assigned.
3. Chart Recorder Fuse (FCR) blown.
Configuration identification for the models covered herein may be obtained on the Container Products Group Infor-
mation Center by authorized Carrier Transicold Service Centers.
a. DataReader
The Carrier Transicold Data Reader (see Figure 4.12 ) is a simple to operate handheld device designed to extract
data from the DataCORDER and upload it to a PC. The Data Reader has the ability to store multiple data files.
Refer to Data Retrieval manual 62-10629 for a more detailed explanation of the DataReader.
