Disabling the Distribution Shaft Alarm
Alternatively, you can turn off the alarm by pressing and holding the
button for 5 seconds with the shaft speed channel selected.
The display will then show ‘OFF’ when this channel is selected. The
alarm function will stay off until the instrument is unplugged and
plugged back in again.
Alarm Delay Time
Some crops – notably oilseed rape (canola) are drilled at very low rates
so the seed shaft runs extremely slow and the instrument may sense
that the shaft has actually stopped, thus triggering the shaft speed
alarm. The programmable delay time can prevent the alarm being trig-
gered needlessly in such a situation.
When drilling at higher rates, a long time delay is equally undesirable.
In this case a shorter time delay can be programmed.
Default delay time = 40 seconds
Minimum delay time = 5 seconds
Set Alarm Delay Time
1. Press and hold the button while plugging the
instrument into a power source to enter program mode 2.
2. Press to select the channel.
3. PRESS to select the digit to change.
4. HOLD to change the selected digit.
5. RELEASE to select the next digit and repeat as
above, otherwise unplug the instrument, then plug in again to re-
sume the normal display mode.
