point the pump will restart and run the system to the set
point pressure.
NORMAL: This feature shuts the system down if a pump
runs empty in constant pressure mode.
Once the pumps have been set to this mode, they will
operate independently from one another. Each pump will
operate at its defined limit and rate. Independent mode is
the default setting for the pump.
When you select a command such as STOP or REFILL, the
display will prompt you to designate which pump to stop or
refill. Only the designated pump will stop; the other pumps
will continue to run.

In an emergency situation, toggling the On/Standby switch will
cause all pumps to immediately stop.
