3.5.2 MAKING 10-PIN CABLE CONNECTIONS

To connect a device using a 10-pin connection:
1. Remove the cover from the 10-pin connector.
2. Align the grooves on the sensor connector (male), with the connector on the
logger (female).
3. Push the connector into place and then twist the outer ring of the male
connector until it locks.

3.5.3 NOTES ABOUT MULTIPLE-CHANNEL AND ADDRESSABLE LOGGERS

■
For ease of wiring, sensor cables should be inserted into the cable glands
on multiple-channel loggers from left to right.
■
Sensors should be wired into the channels of a logger in sequence starting
with Channel 1.
■
Do not wire sensors into the terminal blocks marked '
on a multiple-channel logger.
■
Multiple-channel loggers and addressable loggers stop trying to read an
empty channel after two attempts. The logger will read all channels at the
top of every hour; it will resume sampling when it detects a sensor.

3.5.4 SEAL THE LOGGERS

Seal the loggers using the instructions in Section 3.2.3.
Important! Make sure the cover seals tightly and evenly.
WARNING: Single-channel enclosure lids are square but not symmetrical. They
must be oriented correctly; attempting to seal a misaligned lid could strip the
threads and/or allow moisture to enter the enclosure.
