Prepare Hoses for Sensors
Refer to Figure 37
DICKEY-john Recon-II blockage sensors require a
hole in the hose for the detectors . The sensor has flex-
ible flaps which are tie-wrapped around the seed hose.
The long flap
goes over the short flap .
Note: Use a hole saw to make the hole. Use a high speed
drill (to minimize rough edges), and cut slowly (to
minimize risk of drill-through).
Using a drill bit is likely to damage the hose.
Refer to Figure 38 (showing hole on top)
100. Drill one hole in each secondary seed hose at each
tower. Check the first hole for sensor fit before drill-
ing the remaining holes.
The hole location is approximately:
13in (33cm)
from where the hose enters the tower.
The hole diameter is:
11 ⁄
16
to 3 ⁄
4
in (17-19mm)
Make the hole on the underside of the hose (toward
center of tower), or rotate the hose to hole-under
after drilling or installing sensor.
Install Blockage Sensors
Refer to Figure 39
101. Select one:
467420352S1 RECON II
102. Orient sensor with signal lead toward opener.
Insert the detector head in the hose hole.
Wrap the short flap around the hose.
Wrap the long flap over the short flap.
Check that the long flap overlaps by at least 1 ⁄
4
in
(6mm), but by no more than 1in (25mm). If the flap
is too long, cut off any excess. Re-check overlap.
103. Select two ties from either:
110110050 TY WRAP BUNDLE 50-14"
110110099 TY WRAP BUNDLE 100-14"
Secure the sensor to the hose with ties.
