1. Overview
The HE-VA Auto-Controller enables fully automatic control of the seed rate of
HE-VA Multi-Seeder.
The HE-VA Auto-Controller automatically maintains a preset application rate as
forward speed varies, with on-the-go adjustment of rate.
The instrument measures and indicates:
Forward Speed
Part Area and Total Area worked
Seed Application Rate (kg/ha)
Low Hopper Level
There are also audible and display alarms for,
Minimum / maximum forward speed (beyond which the programmed seed rate
cannot be maintained).
Feed motor stopped (no feedback)
Feed motor stalled
The head unit is powered on and off via a toggle switch on the rear of the instrument.
A pushbutton switch in the cab is used to manually switch the feed motor on and off.
The feed motor is also switched on and off automatically via the implement-mounted
cutout finger switch as the implement is raised and lowered.
Area totals and all calibration data are automatically stored in memory when the
instrument is powered off.
The system must be initially calibrated for the seed being applied. Seed calibration is
very simple to undertake via a priming switch provided on the junction box fitted on the
Multi-Seeder.
1.1 Programming Modes
There are 5 programming modes with various calibration factors and default settings.
Access to the programming modes is required for some settings that may be changed
as part of the normal operating procedure. Changing these settings is described with
the operation instructions (sections 4,5,6,7 and 8).
Other settings are made on installation and do not normally need to be changed.
These settings are appended to in the back of this manual (section 9). The operator
does not normally need to refer to them.
NOTE: The instrument front panel appearance may be slightly different to that illustrated.

2.1 The Head Unit
Confirm with the operator on where to mount the head unit in the cab. It must not
restrict the view out of the cab, nor impede the use of the controls. The head unit is
fitted with a 1-metre flying lead terminating with an 8/10-way IDC type connector, ready
for connection into the "Terminator" junction box.
The head unit is supplied with mounting kit ref: TJ235 comprising the following parts
(fig. 2):
1 Long Bracket
1 Short Bracket
3 Clamping Knobs
1 Cover Plate
1 Mounting Plate
2 Self Tapping Screws
1. Snap the cover plate into the recess of the long
bracket (it only fits one way).
2. The instrument mount is designed to offer maximum
flexibility in positioning the head unit, either from the
right hand side of the cab, from the dashboard or
from an overhead position.
3. Assemble the two brackets, and mounting plate with
clamping knobs, and attach to the head unit.
NOTE: Either the long or short bracket can be
attached to the head unit, whichever gives the
most suitable orientation.
Having established the orientation for the
bracket, fix the mounting plate to the cab
with the self-tapping screws provided.
Do not drill into a ROPS or FOPS frame.
If you are fixing the mounting plate to plastic e.g. the dashboard or other cab moulding,
it is recommended to use M4 screws with mudwing washers to strengthen the
mounting point.
Do not attempt to adjust the mounting bracket assembly without first
slackening off the clamping knobs sufficiently. You will only succeed in
damaging the bracket otherwise.

2.2 The ‘Tractor Terminator’ Assembly
Mount the pushbutton Cutout Switch in a convenient position using 2 self-tapping
screws.
Remove the lid of the terminal box by squeezing the sides and connect the head unit
lead as shown in figure 3 below.
The Terminator is not a waterproof enclosure. Locate it where it is afforded protection
from possible water ingress and for neatness e.g. behind a trim panel or console.
Figure 3: Head unit connection
NOTE: The head unit receives its power supply via the junction box (see figure 1).
The power supply terminals in the Terminator are not used.
The circular (CPC) connector trails to the back of the tractor to connect with the 6-
metre extension lead going to the junction box.

2.3 Power supply
The system is powered via the three pole plug/connector.
2.4 Radar sensor
The radar sensor may be fitted either to the Multi-Seeder or to the tractor. For fitting
instructions please refer to the separate instruction leaflet ref. S/DC/500-10-511
provided.
Connecting a Multi-Seeder-mounted radar sensor:
Simply connect the radar sensor lead to the lead from the junction box
(3-way connector). Coil any excess lead near the junction box and secure
the lead from the sensor at regular intervals using the cable ties provided.
Connecting a tractor-mounted radar sensor:
Open the junction box and remove the sensor extension lead with the
3-way connector (fig. 4). Plug the hole to prevent water ingress.
Figure 4
Connect the extension lead to the sensor and route back to the Terminator junction
box. Where possible follow the existing wiring loom and secure at regular intervals
using the cable ties provided.
Remove the lid of the terminal box by squeezing the sides, cut off excess cable length
and connect the head unit lead as shown in figure 5.

sensor lead

Figure 5
The default speed sensor calibration factor (SSF) programmed in the head unit =
‘7.78’ (millimeters/pulse). This is theoretically correct for the radar sensor when it is
installed at exactly the specified angle to the ground. Often though, the sensor may
not be exactly at the prescribed angle. It is therefore recommended that to ensure
accurate speed measurement, you check the calibration value by performing an
‘Autocal’ procedure (please refer to section 4.4).
2.5 Cutout switch
The implement-mounted cutout finger switch enables the system to automatically start
and stop operation as the implement is lifted and lowered.
It therefore needs to be mounted in a suitable position to operate as the implement
enters work.
NOTE: For fitting instructions please refer to the separate instruction leaflet
ref. S/DC/500-10-121 provided.
