Before programming the controller to accept the analog signal, you
must know the maximum flow rate (Constant Flow) or the maximum
pressure (Constant Pressure).
The high and low limits you enter cannot exceed the pump specifica-
tions: Normal input = 10V.
For the 4-20ma input option the negative output wire connects to
DIGITAL GROUND. The positive output wire connects to ANALOG
INPUT 1-4.
To determine the analog voltage range, use the formula explained
below:
where:
• FS = Maximum flow rate or Maximum pressure (Full Scale):
This is the same value entered when setting
in Section 3.8.7 "LIMITS", as described for
.
FLOW
• V = Volts per unit of flow or pressure
• U = Incremental unit of flow or pressure
• Vmax = Maximum input voltage
For the 4-20ma input option the maximum flow or pressure sets the
limit at 20ma. No other formula applies.
