Hopper Contents Display
This channel gives either a simple low level alarm or displays the hopper
contents, depending on how the system is configured.
9.1
Low Level Alarm (using Hopper Level Sensor)
If the hopper is fitted with a level sensor, when you select this channel it will
briefly display “
1
” to indicate that the alarm is enabled
NOTE: This is the default setting. If “
0
” is displayed then the alarm is disabled.
When the hopper contents fall below the sensor, the display will default to
this channel and flash “
Alar
”, and the instrument will beep 5 times. You can
temporarily ignore the alarm by selecting another channel, however the
instrument beeps and returns to this display after 30 seconds.
The hopper level alarm does not function when the forward speed is less
than 2km/hr.
9.2
Weight display (Qty left in hopper/ Qty dispensed)
The instrument must already be set the calibration mode for “Volumetric”
hopper contents (if necessary, refer to the Installation/Calibration manual).
The system calculates the theoretical quantity in the hopper, displaying either
the total weight dispensed or the quantity remaining in the hopper,
depending on how the instrument is configured in the calibration mode.
If kg units are selected, the units are kgs up to “9999” thereafter the decimal
point indicating the readout is in tonnes (to the nearest 10kg) e.g. 10.10
tonnes.
NOTE: On systems with rate control, the weight calculation is based on the belt
speed and the area covered. The simpler system without rate control
calculates from the programmed application rate and area covered.
Therefore, the accuracy of the hopper contents display is dependent on the
programmed rate figure matching the actual rate being applied.
