1. Overview
The Micrometer Applicator Control System enables fully automatic control of
the seed rate of the Stocks Micrometer pneumatic Applicator.
The Micrometer 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 drill.
1.1 Programming Modes
There are 4 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 and 7).
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.

2.2 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.
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.

2.3 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 on the Micrometer
(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.

2.4 Power supply
The system is powered via the COBO connector.
2.5 Radar sensor
The radar sensor may be fitted either to the drill or to the tractor. For fitting
instructions please refer to the separate instruction leaflet ref. S/DC/500-10-511
provided.
Connecting a drill-mounted radar sensor:
Simply connect the radar sensor lead to the lead from the Micrometer junction
box (3-way Weatherpak 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 Micrometer junction box and remove the sensor extension lead with
the 3-way WeatherPak 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 below.

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).
2.6 Cutout switch
The implement-mounted cutout finger switch enables the system to
automatically start and stop operation as the drill is lifted and lowered. It
therefore needs to be mounted in a suitable position to operate as the drill
enters work.
NOTE: For fitting instructions please refer to the separate instruction leaflet ref.
