3.7.2.3 GENERAL SETTINGS - ON/OFF HYDRAULICS
The On/Off hydraulic output can be made to pulse or to be solid.
On/Off (Low) Settings
Min Pulse Up = 50ms
F-Sampling = 4.0%
Min Pulse Dn = 50ms
Max Pulse Up = 250ms
Max Pulse Dn = 250ms
Max Up = 100%
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.
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 bucket or blade
may not move at all when small adjustment is required. If set to high, the bucket
o
or blade will overshoots 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 bucket or
blade may not move at all when small adjustment is required. If set to high, the
o
bucket or blade 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 to high, the bucket or blade
o
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 to high, the bucket
o
or blade may move too fast and overshoots the target. If set too low, movement
may be too slow.
6. MAX Up:
Maximum signal current that is applied to move hydraulics in
upward direction.
7. MAX Down:
Maximum signal
t
applied to move hydraulics in
current hat is
downward direction
.
8. Direction
: Normal or Reverse direction for hydraulics movement. When
Reverse direction is selected, the
will activate Down hydraulics when Up
DUO2
control is applied and will activate UP hydraulics when Down control is applied.
If
(non-pulsing) hydraulic output is required, set Min Pulse Up, Min
constant
Puls Down, Max Pulse Up and Max Pulse Down to be equal with a value of
e
1/Sampling x 1000. For example, if ‘F-Sampling’ is set to 4Hz, set all to 1/4 x
1000 = 250ms.
