Speed Control Setup
SPEED SIGNAL CONFIGURATION
In speed control, the desired running speed may be selected in one
of three ways:
x Keypad entry
x Speed signal (4-20ma) via Analog Input AI-2 (Default)
x Fieldbus control
The following details the use of a speed signal to set the operating
speed of the pump. If you are using Fieldbus control to do this,
please refer to OPTIONS & FEATURES.
SIGNAL SOURCE – Using parameter 16.02, select where the speed
signal will originate.

Options:
Keypad (default) – A
manually entered value
Analog Input – A 4-
20mA signal is sent to
PumpSmart (Via AI-2)
Fieldbus – An operating
speed is issued from DCS
via a digital bus.

NOTE - SETTING AI2 MAX (16.03) AND AI2 MIN (16.04) IS STILL
REQUIRED IF USING KEYPAD OR FIELDBUS CONTROL
If you are using an analog speed signal to set the operating speed
of the pump, signal MAX and MIN settings are required to properly
scale the signal.
Analog Input AI-2 is the default channel for receiving an analog
input speed signal. This channel is designed to accept a 4-20 mA
current signal. In this case, setting of parameters 16.03 AI2 MAX
and 16.04 AI2 MIN is required.
AI2 MAX - This refers to the speed value that corresponds to the
max signal [20 mA].
Example- if you want your process to run at 3600 RPM when
the 4-20 mA speed signal is 20 mA, then you would enter in
3600 into parameter 16.03
Example (2) - If you are using Keypad or Fieldbus speed entry
method, a value here would limit the entry value. If the AI-2
