Installation Overview 

Unpacking the System 

Installing the Mast 

Installing the Sensor Transmitter 

Installing the Surge Arrestor 

Installing the Orion 420 Weatherproof Enclosure 

Connecting the Sensor Transmitter to the enclosure 

Connecting the enclosure to the PLC 

Unpacking the Unit 

The sensor transmitter comes in a custom shipping container. Be careful 
when removing the device. 

CAUTION

: Beware of damaging any of the wind transducers located at 

the top of the three antennas. Dropping the device can break or damage 
the transducers. If the antenna bends or twists, the re-aligning can be 
difficult or impossible. 

Unpack the Orion 420 weather station and verify that all parts are 
included. 

1. Standard system includes: 

  Orion Sensor Transmitter 

  50 ft sensor cable + additional cable length if ordered 

  Orion 420 Weatherproof Enclosure 

  User Manual 

Inspect all system components for obvious shipping damage (Refer to 
“Important Notice: Shipping Damage” in case of damage). 

Save the shipping carton and packing material in case the unit needs to 
be returned to the factory. If the system does not operate or calibrate 
properly, see Section 6: Maintenance and Section 7: Troubleshooting, for 
further instructions.
