HE-VA Auto-Controller AC-Lite - May 2016

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.
