3.7.2.3 GENERAL SETTINGS FOR ON/OFF
HYDRAULICS
The On/Off hydraulic output can be made to pulse or to be solid.
On/Off (Low) Settings
F-Sampling = 4.0hz
Min Pulse Up = 50ms
Max Pulse Dn = 250ms
Max Up = 100.0%
Max Pulse Up = 250ms
Min Pulse Dn = 50ms
2. Min Pulse Up: the duration of the up pulse when the signal from the sensor is
just below the ‘ON TARGET’ (green) band. If set too low, the blade/bucket may not
move at all when small adjustment is required. If set too high, the blade/bucket will
overshoot the target.
3. Min Pulse Down: the duration of the down pulse when the signal from the sensor
is just below the ‘ON TARGET’ (green) band. If set too low, the blade/bucket may
not move at all when small adjustment is required. If set too high, the blade/bucket
will overshoot the target.
4. Max Pulse Up: the duration of the up pulse when the signal from the sensor is
below the ‘ON TARGET’ (green) band by an amount that is greater than or equal to
the proportional range of the sensor. If set too high, the blade/bucket may move too
fast and overshoots the target. If set too low, movement may be too slow.
5. Max Pulse Down: the duration of the up pulse when the signal from the sensor is
above the ‘ON TARGET’ (green) band by an amount that is greater than or equal to
the proportional range of the sensor. If set too high, the blade/bucket may move too
fast and overshoots the target. If set too low, movement may be too slow.
Note: The maximum value for Max pulse up and Max pulse down is dependent on
the F-sampling setting. Example: If F-sample is set to 12Hz, the max pulse up and
down cannot go higher than 83ms.
6. MAX Up: Maximum signal current that is applied to move blade/bucket in upward
direction.
7. MAX Down: Maximum signal current that is applied to move blade/bucket in
downward direction.
8. Direction: Normal or Reverse direction of blade/bucket movement. If Reverse
direction is selected, the .CAN will activate ‘Down Hydraulics’ when up signal CB.D2
is applied and will activate ‘UP Hydraulics’ when down signal is applied. If solid
(non-pulsing) hydraulic output is required, set Min Pulse Up, Min Pulse Dn, Max
Pulse Up and Max Pulse Dn to be equal with a value of 1/Sampling x 1000. For
example, if ‘F-Sampling’ is set to 4Hz, set all to 1/4 x 1000 = 250ms.
1. F-Sampling: frequency of the pulsing
hydraulic signal. A higher number gives
more rapid bursts of adjustment. A lower
number gives slower bursts of adjustment.
The adjustment range is from 1 - 16Hz. The
default value is set to 12Hz.
