5. Repeat this procedure for the remaining control channels. Multiple runs
and averaging results are unnecessary. Liquid must be primed before
running a system response. The UNLOAD feature can be used to
prime the pump.
FINE TUNING SYSTEM RESPONSE CONSTANTS
The Automatic System Response routines are not necessarily exact.
Operators may want the system to respond faster or slower than calculated
by the automatic routines. These values can be adjusted slightly to tailor the
response to operator needs.
IMPORTANT: Automatic routines must always be run prior to
modification to establish basic values. The following are
a few general guidelines.

SYS RSPNS CONSTANT
If the control system responds slowly to changes in speed and is slow to
start, the SYS RSPNS value should be increased. If the system is
oscillating around the target APR, the SYS RSPNS may be too large and
should be decreased. Excessive oscillation should be limited to ±5% of the
target APR to minimize wear on the PWM valve. Most systems can be
tuned by altering only this value.
