deadband = 0.05 m, arbitrary setting
P-23 enter option "1", using submersible transducer
P-37 enter "1", convert display ( x1 )
P-68 enter "1", fill damping 1 m / min
P-69 enter "
.2", empty damping 0.2 m / min
P-74 enter option "2", fail-safe low to protect pumps
P-75 enter "
.5", fail-safe timer
at a maximum draw rate of 0.2 m / min, this
would protect pumps. If a loss of echo occurred
at 0.5 m, after 30 sec the level would equal
that of acceptable low level alarm and the
pump would shut off.

Pump Run-On
Pump run-on is a special feature designed to allow the pump assigned, temporarily
(sequential loop) or permanently ( fixed roster ), to the lowest OFF setpoint to
continue pumping after it has reached that OFF setpoint. The duration of run-on is set
by P-30. Only one run-on duration is allowed per interval. The interval is the time
period set by P-29 which begins upon return to the run mode or resumption of power.
No run-on is allowed during the first interval.
Caution: extended pump run-on can lead
to cavitation, causing air lock or pump damage
