8. CS125 internal connectors’ description
The CS125 has four standard IP66 rated glands. The first gland is by default used
by the power/communications line. This comprises the 7-30 V for the main
electronics, and the serial communications wires. The CS125 is supplied with 5 m
cable already connected.
The second gland is used for the 24 V feeds for the hood heaters fitted with a 5 m
cable.
Glands 3 and 4 are spare. If user alarms are connected they usually use gland 3
and if a CS215 is fitted this usually uses gland 4.
If the power cable is incorrectly wired to the CS125 then
damage can be done to the unit.
10 m is the longest length of the cable type supplied
recommended. In particular, additional RS485 communication
should be twisted pair. Please contact Campbell Scientific if
you wish to use a longer length of cable.
Figure 8-1. Connections
A configuration cable, part number 010817, is available from Campbell Scientific
that plugs directly into connector B, in place of the normal connector and cable.
