0 RPM this parameter delays
pump protection faults (2404
and 2407) for the setting time.
The default setting is “0”. Once
the priming delay time is
complete the protection delay
(parameter 2406) becomes
functional. During the priming
delay the pump runs at the
maximum speed setting
(parameter 1401) since it
cannot achieve the set point.

macros this parameter defines
the full-scale feedback (20 mA
setting) of the primary process
transmitter at AI2. This parameter
also correlates to the maximum
value of Reference (set points) 1
and 2. For the Speed Control
macro this parameter scales the
maximum (20 mA or keypad )
speed setting. Note when units
are in Ft, M, In or Cm: AI2 Max
is always based on a specific
gravity = 1 regardless of setting
for parameter 1506. Actual
pressure signals in Ft, M, In or
Cm are corrected for specific
gravity by the firmware. Signal
can be quadratic or linear.
