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.

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.

Figure 2 : Head Unit Mounting Kit

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.

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

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

Remove the radar sensor lead 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.

Figure 5 1 2 3

Brown (+V) Blue (0V) Yellow/Green (Sig)

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.

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

3.2 Power On/Off Switch the head unit on via the toggle switch on the rear of the instrument. The instrument powers up and displays the software version installed e.g. ‘A704’ then ‘Exxx’ then ‘Rxxx’ (software version WZ704-xxx rev.xxx). It then enters its normal operating mode and displays the forward speed channel. Select any other channel by pressing the (Channel Select) button once or more. When the Multi-Seeder is out of work, the instrument will continue to display the selected channel.

3.3 Work Status Indicator The indicator is used to indicate the channel to which the information on the display relates. It also shows the working status of the Multi-Seeder. If the cursor is flashing then the Multi-Seeder is out of work, if the cursor is on continuously then the Multi-Seeder is in work.

3.4 Starting and Stopping the Seeding The pushbutton switch is used to manually switch the feed motor on and off when the Multi-Seeder in work*. The Multi-Seeder is also fitted with a cutout finger switch so that the feed motor starts and stops automatically when the implement is lowered and raised e.g. on the headlands. * The pushbutton switch is not effective when the implement is raised out of work, as it is overidden by the operation of the cutout switch mounted on the implement.

3.5 Pre-start function On commencing a bout, the seed motor only starts as you begin moving off. However, it takes a short period for the seed to traverse the pipe to the coulter. The result is an unseeded area at the beginning of a bout. To avoid unseeded patches due to the delay in seed delivery, once positioned and stationary at the start of the bout, press the outside right switch (“RATE +”). The prestart function is activated and the motor then runs at the calibration speed, so that seed is planted as you move off. The pre-start function is timed to run the motor at the calibration speed for a number of seconds equal to the implement width in metres (e.g. 4m implement = 4 seconds prestart). After this time and the implement is moving forwards, the system reverts to normal proportional control for the seed rate set. However, if after this time the implement is still stationary, the motor will automatically switch off.

11

HE-VA Auto-Controller AC-Lite - May 2016 NOTE: The default pre-start time is 4 seconds, however it can be changed if required in Cal Mode 2-Channel 6 (ref. section 9).

3.6 Cutout Alarm If the forward speed exceeds 2km/h with the Multi-Seeder ‘out of work’, the instrument will alarm by beeping and flashing ‘C.out’ every 5 seconds. The alarm will continue until the implement is lowered into work. The forward speed at which this alarm is displayed can be modified by entering Cal Mode 5 and adjusting the speed on Channel 1. If set to 8.00, then it will not alarm until above 8 km/h.

3.7 Simulated Speed If there is a problem with the forward speed, or for testing, a ‘Simulated Speed’ can be used on the instrument. To enable this, disconnect the speed sensor, enter Mode 2 and while on Channel 1, use the + and – buttons to set a simulated speed value. Once the correct speed is selected, press the Ha->0 button, and the instrument will now use this speed until it is next powered down.

3.8 Application Rate – kg/ha or seeds/m² The system can display application rate in either kg/ha or seeds/m². To switch between the two settings, enter Cal Mode 3 and switch between ‘Rate’ kg/ha or ‘Pop’ seeds/m² on Channel 1. The Thousand Grain Weight for that seed can then be entered on Channel 2.

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

4. Forward Speed Display 4.1 View Forward Speed

The forward speed is derived from a radar sensor fitted either to the Multi-Seeder or the tractor, depending on your particular installation. The speed is displayed in km/h only.

4.2 Minimum Speed Alarm

Figure 6: Select Fwd. Speed channel

As part of product calibration, based on the resulting calibration factor, the instrument automatically calculates the minimum forward speed below which the system cannot maintain the programmed seed rate. With the Multi-Seeder in work, if the forward speed goes below this threshold the instrument display defaults to channel 1, flashes the actual speed and beeps continuously. The alarm will continue until speed is increased above the threshold. It may be cancelled temporarily by selecting another channel but will revert to channel 1 and repeat the alarm after 30 seconds until speed is increased. NOTE: The application rate will not remain proportional below the minimum speed threshold. The feed motor cannot run below 3 rpm, resulting in over-application.

4.3 Speed Sensor Calibration The forward speed is derived from the speed sensor factor (“SSF”) – the distance travelled in millimetres for each pulse received from the radar speed sensor. The default factor is 7.8mm per pulse from the sensor. This will only result in a correct speed display if the sensor has been mounted at the correct angle to the ground. Failure to programme the correct speed sensor factor will also result in the drilling rate being displayed incorrectly. Auto-calibration is likely to be more accurate than manual calibration and therefore it is recommended to perform an "Autocal" routine (see overleaf).

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

4.4 ‘Autocal’ Speed Calibration Auto-calibrate in field conditions for maximum accuracy. 1. Place two markers 100 metres apart and position some reference point on the tractor (e.g. the cab step) opposite the first marker. 2. Select the forward speed channel. 3. Press and hold the CAL button until the cal factor appears on the display. (7.8)

4. Continue holding the CAL button and press Figure 7: Start AutoCal the Ha>0 button. The display will show "AUtO" ready to start the test run (fig. 7). 5. Drive up to the second marker and stop exactly opposite the marker. The instrument counts and displays the pulses received from the speed sensor over the measured distance. NOTE: The instrument only displays up to 9999. Beyond this number of pulses it displays the first 4 digits of a five-digit number, however the pulses are still being counted internally.

6.5 Product Calibration Ensure the feed roll setup is appropriate for the intended seed type, application rate and forward speed range for application. Please refer to the relevant sections of the HE-VA ApS Fitting and Operating Instructions if necessary. 1. Place a container under the seed outlet of the metering unit then press and hold the PRIME button to dispense the product.

2. The instrument automatically switches to the programme mode, and the display will count up the theoretical weight (in grams) of product based on the calibration factor currently stored in memory. 3. Once you have dispensed sufficient product, release the priming switch and weigh the product metered out. The theoretical weight will remain flashing on the display. NOTE: If the priming switch is held for long enough to exceed 9999 grams then the instrument will simply show ‘HiGh’, informing the operator that he must re-test to ensure the weight does not exceed 9999 grams. Simply release the PRIME button and press again when ready to restart the count from zero. 4. Adjust the displayed weight to match the measured weight using the RATE + or RATE - buttons. 5. Press the Ha>0 button once to display the calculated minimum forward speed (see note). 6. Press the Ha>0 button again to save the new calibration factor. The instrument displays ‘donE’ to indicate the new factor is now stored. After 3 seconds, the instrument reverts back to the normal operating mode. NOTE : The instrument makes the calculation from the entered working width, target application rate, and the metered weight delivered whilst calibrating. If you find that you cannot achieve your desired field speed, then re-configure the feed roll assembly and repeat the calibration procedure.

9.2 Fault Diagnosis Condition When in work and moving, the Instrument displays ‘C.out’ and beeps every 5 seconds

When in work the instrument flashes ‘ALAr’ and beeps. When in work the instrument defaults to the rate channel, displays ‘FaiL’ and beeps every 30 seconds. The metering roll does not turn.

When in work the instrument defaults to the rate channel, displays ‘StAL’ and beeps every 30 seconds. The metering roll does not turn. When in work the instrument defaults to the application rate channel, flashes a rate lower than the target and beeps continuously. When in work the instrument defaults to the forward speed channel, the speed display flashes and beeps continuously.

24

Possible reasons The forward speed is above 2km/h while the Multi-Seeder is out of work. The cutout switch is not operating correctly when the implement is lifted or lowered. Hopper level is low. The metering motor has stopped due to an internal fault with the motor or the encoder, or the external power supply. First switch the instrument off and back on to try and clear the fault. Otherwise, check the wiring connections (both power supply and encoder) and try again. The metering motor has stalled. It has automatically stopped to prevent further damage. Investigate the metering mechanism. The application rate is low because the forward speed is too high and the target motor speed cannot be achieved. Reduce your speed or change the metering roll and recalibrate. Forward speed is too low. The metering roll is at its minimum possible rpm. Increase your speed, or if this would be too fast, change the metering roll and recalibrate. If you find that the minimum forward speed is too high at low application rates you should change the feed roll to a lower volume roll and redo the product calibration.
