3.6.6 Sampling Type (dCF05 & dCF06)
Three types of data sampling are available average:
snapshot and USDA. When configured to average, the
average of readings taken every minute over the recording
period is recorded. When configured to snapshot, the
sensor reading at the log interval time is recorded. When
USDA is configured, the supply and return temperature
readings are averaged and the 3 USDA probe readings
are snapshot.
3.6.7 Alarm Configuration (dCF07 - dCF10)
The USDA and cargo probe alarms may be configured
to OFF, ON or AUTO.
If a probe alarm is configured to OFF, then the alarm for
this probe is always disabled.
If a probe alarm is configured to ON, then the associated
alarm is always enabled.
If the probes are configured to AUTO, they act as a
group. This function is designed to assist users who
keep their DataCORDER configured for USDA
recording, but do not install the probes for every trip. If all
the probes are disconnected, no alarms are activated.
As soon as one of the probes is installed, then all of the
alarms are enabled and the remaining probes that are
not installed will give active alarm indications.
3.6.8 DataCORDER Power-Up
The DataCORDER may be powered up in any one of
four ways:
1.
Normal AC power:
The DataCORDER is powered
up when the unit is turned on via the stop-start switch.
2.
Controller DC battery pack power:
If a battery pack
is installed, the DataCORDER will power up for
communication when an interrogation cable is plugged
into an interrogation receptacle.
3. External
DC battery pack power:
A 12 volt battery
pack may also be plugged into the back of the
interrogation cable, which is then plugged into an
interrogation port. No controller battery pack is required
with this method.
4.
Real Time Clock demand:
If the DataCORDER is
equipped with a charged battery pack and AC power is
not present, the DataCORDER will power up when the
real time clock indicates that a data recording should
take place. When the DataCORDER is finished
recording, it will power down.
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 voltage 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 DataCORDER 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.
3.6.9 Pre-Trip Data Recording
The DataCORDER will record the initiation of a pre-trip
test (refer to paragraph 3.5) 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 3--9 for a description of the data stored in
the DataCORDER for each corresponding Pre-Trip test.
3.6.10 DataCORDER Communications
Data retrieval from the DataCORDER can be
accomplished by using one of the following;
DataReader, DataLINE/DataView or a communications
interface module.
NOTE
A DataReader, DataLINE/DataView or a com-
munications interface module display of Com-
munication 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
misassigned.
3. Chart Recorder Fuse (FCR) blown.
Configuration identification for the models covered
herein may be obtained on the Container Products
Group Information Center by authorized Carrier
Transicold Service Centers.
a. DataReader
The Carrier Transicold Data Reader (see Figure 3--6) 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 62-02575 for a more
detailed explanation of the DataReader.
