1.9 BHECU (Blocked Head
Electronic Control Unit)
A I/O ECU (EM-24) (Figure 1.20) and BH Sensor
(Figure 1.21) are available to use with the X35/
Bourgault SRC programs.
The I/O ECU is installed on the secondary manifold
stand and communicates with the BH sensor.
- the sensor is installed "in-line" on one tertiary
line per secondary manifold;
- there is a maximum of 20 BH sensors per unit.
The information from this BH sensor is then sent
back to the X35 monitor and is displayed on the
Bourgault SRC program. Refer to Section 13.3
- X35 Blockage Monitoring for more installation
information.
1.10 Granular Sectional Control
harnesses
There are 2 control harnesses that run from the I/O
ECU to control up to 10 sections on the unit. One
harness controls the section valves and the other
harness sends the section sensor feedback to the
ECU.
1.11 Section Control Valve Proximity
Sensor
Refer to Figure 1.22. A proximity sensor is used
to determine position of the section control valve.
The sensor provides an alarm on the monitor
when a valve should be open (for seeding), but is
partially or completely closed.
