1 Halo shows
ickering
readings
Drilling
environment
When drilling in hard or rocky ground, the inclination readings can be prone to misreading
or abnormal behaviour. The inclination sensor is sensitive and much like hitting a spirit
level with a hammer, drilling in hard or rocking ground can cause issues with the Halo sys-
tem. If the readings are not useful in such applications, either the operator can bring the
drive to a halt to take a valid reading from the Halo at rest, or disconnect the Halo whilst
that ground is making it difcult to produce a useful reading.
2 Halo freezes Drilling
environment
If the Halo sensor becomes overwhelmed with erratic sensor data from rough ground, it’s
possible for the instruments that senses the inclination to enter an error state. Restarting
the Halo will remove this error state.
3 Halo shows
incorrect
readings
Zero mode is
active (using
the Halo
battery)
In normal drilling mode, the Halo will display white in the centre of the LED array when the
green and red array show. If the centre shows blue, the zero mode is activated. To return
to normal drilling mode, either press the zero mode button again and the LEDs will ash
all white for a moment, or turn the Halo off and on by unplugging the battery.
4 Halo shows
incorrect
Readings
Start-up
calibration
incomplete
Make sure the auger drive is hitched and hanging approx. plumb before connecting the
battery. After connecting the battery, the drive with the Halo must be still for 30 seconds.
During this time you may notice the lights moving even though the drive is still. After 30
seconds, the Halo will have nished the start-up calibration will be showing the correct
LED sequences.
5 Halo doesn’t
turn on
Faulty 12V
supply
Check that the red light is glowing on the cab cable (12V cigarette plug). If the red light
isn’t displaying, the 12V socket may be faulty.
6 Halo doesn’t
turn on
Damaged
cable
extension
Check for any damage to any exposed cables. Cable damage could indicate a
discontinuity and require a replacement.
