Setup and Tuning
The operating parameters of the system: Threshold, Max
Out, Low Range, Ramp up, Ramp Down are preadjusted
at the factory with preset values, called default settings.
For optimum machine performance, these settings may
require fine-tuning. This section describes the procedures
for charging the settings of each of the five (5) functions
for each direction of handle movement.
These setting adjustments can be made in two (2) ways:
Normal-Active or Bench-Static. In the Normal-Active
mode, the adjustments will be made with the equipment
and joystick operational. In the Bench-Static mode, Joy-
stick/DIGISENSORs may or may not be wired to the
SUPERFLEX Controller. For best results, it is recom-
mended that all adjustments be made in the Normal-
Active mode.
In the Normal-Active mode, set-up and tuning of all adjust-
ments are active (live) and the equipment will respond
accordingly, if hydraulic and electrical power are applied
to the electrohydraulic valves. The operator is cautioned
to be in an area clear of obstructions and to be cautious
during the set-up procedure, as changes in the data can
cause sudden motion of the equipment.
To make Normal-Active adjustments, move the joystick
handle in a direction. Controller #1 or #2 and Direction A
or B will be shown on the OPTIMIZER LCD display. For
best results, operate and make adjustments for all func-
tions in both directions of handle travel.
