6.2.1 Preparing the Mounting Structure
1.
Secure a CM20X crossarm to a tripod or other vertical structure using a
CM210 crossarm-to-pole bracket (pn 17767).
2.
Point the horizontal arm into the direction of the prevailing wind.
3.
Tighten all fitting set screws.
Do not carry the EC150 by the arms or the strut between the
arms. Always hold the sensor by the block where the upper
and lower arms connect.
6.2.2 Mounting EC150 with Optional CSAT3A
The guideline below gives general instructions for mounting an EC150 and
optional CSAT3A to a mounting structure. The order of assembly will
somewhat be determined by the user’s application; primarily the height of the
tower. Steps 6, 7, and 8 should be performed in sequential order.
Please refer to all steps and the referenced figure of this section before deciding
on an assembly strategy. In general, Campbell Scientific suggests that if the
equipment is to be mounted at heights above what can be reached while
standing, to preassemble as much as possible and then hoist that assembly into
a position to be mounted on the appropriate crossarm.
1.
Attach CSAT3A to the proper mounting bracket according to the
CSAT3A serial number.
•
If using a CSAT3A with current design (serial numbers 2000 and
greater), attach the EC150/CSAT3A mounting bracket (pn 32065;
) to the CSAT3A using the three included screws
and then bolt the CM250 leveling mount (pn 26559) to the
threaded hole of the CSAT3A sensor block.
•
If using a CSAT3A with original design (serial numbers less than
2000), align and tighten the bolt on the pn 26786 mounting
bracket to the bottom of the threaded hole on the CSAT3A sensor
block. Then bolt the CM250 leveling mount (pn 26559) to the
threaded hole on the bottom of the pn 26786 mounting bracket.
2.
Install the assembly to the end of the crossarm by fitting the CM250
leveling mount over the end of the crossarm.
3.
Tighten the set screws on the leveling mount.
4.
Install the EC150 gas analyzer head to the EC150/CSAT3A mounting
bracket by tightening the mounting screw and loosely thread the
mounting bolt into the analyzer head.
5.
Align the analyzer parallel with the vertical plate of the mounting
bracket and insert the mounting screw and bolt into the slot of the
mounting bracket.
6.
Carefully slide the analyzer forward to the desired position. For a
