Pump Start/Stop Settings
1. Base Load Pump settings.
a. Start% is the percentage of the pressure set point at
which pumps will start to turn on if no pumps are running.
Default value 90%. Input range 75-100%.
b. Base load pump off delay. If pressure is greater the
setpoint for this time period with one pump running, the
pump will shut off. Default value 10 seconds. Input range
1-60 seconds.
3. Peak Load Pump settings.
a. Peak load pump on delay. Time with pump frequency
greater than 5% less than max frequency before the next
pump will start. Default value 0.5 seconds. Input range
0-60.0 seconds.
b. Off delay. If pressure is 20psi greater than the setpoint for
this duration, the next pump will shut off. Default value
0.5 seconds. Input range 0-60 seconds.
3. Frequency settings. Sets the min and max frequencies
a. a.Min frequency. Default value 30 Hz. Input range 25-
50Hz.
b. b.Max frequency. Default value 60 Hz. Input range 25-60
Hz.

Pipe Fill Settings
Pipe Fill Mode will only allow one pump to run until either the
pressure or time requirement is met.
1.
Enables and disables pipe fill. Default Off
2. Only one pump will run when initially starting until this
percentage of the pressure setpoint is reached. Default value
50%. Input range 0-99.9%
3. Will only run one pump when starting until this much time
has elapse, or the pressure setting is reached, whichever comes
first. Default value: 10 seconds. Input range 0-60 seconds.

18 Zero Flow Cut-Off
1.
Time with one pump running until system checks for no flow.
If the system detects no flow, the pump will shut off. Default
value: 1 minute. Input range: 1-3 minutes
2.
Amount that pressure will be raised when the zero flow
check is performed. Default value: 5.0 psi. Input range 1.5-
15.0 psi
3.
Duration that the zero flow check will be performed. Default
value 10 seconds. Input range 1-180 seconds.
4.
Check frequency is the pressure below which the zero flow
checks will be performed. Default value: 40 Hz. Input range
25.0-60 Hz
