Industrial System Installation Manual
Field System with AC Power
The illustration below shows an installation in which the console is located
with the SIM (and, optionally, the AOM) in the field near the sensors. The con-
sole and modules are housed in the Complete System Shelter (CSS). The Com-
plete-System-Shelter Heater might also be included.
AC power is wired, according to code, to an enclosure or shelter containing a
receptacle box and a power adapter. The power adapter cable is routed into the
CSS, where a power Y-cable distributes power to the console and AOM.
The WeatherLink
®
(optional) is connected via a Short-Range Modem Pair and
two-twisted-pair cable to a computer in the office at a distance of up to 8 miles,
depending on the wire gauge used. If a cable to the computer is not feasible,
data may be uploaded to a laptop or other portable computer at the sensor site.
The advantages of this system:
✦
The Console is located near the sensors.
Data may be viewed at the sensor site. In addition to making weather
data available in the field, this is useful for the alignment, adjustment,
and monitoring of sensors.
✦
The WeatherLink cable to the computer can be very long, and (comprising only
four conductors) it is low in cost.
The Link cable is also relatively immune to noise and voltage surges, and
additional protection is low in cost.
