Powering On the A-100NV
The A-100NV is powered on when plugged into the power source. The pump is now ready to be run manually by pressing the Run/Standby button on the display. Or the pump can be programmed to run via 4-20 mA input, 0-10 VDC input, or pulse frequency input.
Display and Layout
The A-100NV has a touchpad display that is easy to read and simple to program. Open the control panel door by sliding the upper and lower slide clamps to the left.

Programming and Running the Pump
The display/touchpad allows for programming of the following features:
- Manual Speed Setting (Mode 1)
- 4-20mA Input (Mode 2)
- 0-10 VDC Input (mode 3)
- Pulse Frequency Input (Mode 4)
- FVS (Flow Verification System)
[ NOTE: If while in the program mode, no buttons are pressed within 20 seconds, the circuitry will automatically return to the run mode, without saving changes.]
Operating Mode 1 – Manual Speed Adjust
In this mode, the pump’s motor speed is set/programmed using the front panel touch pad. The motor speed can be adjusted from 10-100%. (Note: some models have a range of 15% -100% only.)
To adjust the speed:
- Set the pump for mode 1. Press the MODE button until MODE 1 is shown on the LCD display. The %SPEED icon will light. The large 3-DIGIT LCD will indicate the currently programmed percentage of speed.
- Enter the programming mode. At the same time, press the RUN/STANDBY button and the MODE button. A blinking ARROW will point to the word PROGRAM indicating the program mode has been activated.
- Press the FIELD button to select the digit to program. The digit will blink when selected. Press the DIGIT button to change the selected digit. Repeat until all digits are programmed.
- To exit the programming mode, press the RUN/STANDBY button and the MODE button at the same time. The arrow next to the word PROGRAM will disappear.

A blinking ARROW will point to the word MINIMUM, indicating the minimum value is ready to be programmed. The % SPEED icon will blink, indicating the percentage of speed is ready to be programmed.
- Enter the motor speed at the minimum mA input signal value. Press the FIELD button to select the digit to program. The digit will blink when selected. Press the DIGIT button to change the selected digit. Repeat until all digits are programmed.
- Press the mode button. The % SPEED icon will stop blinking and the mA icon will blink, indicating the minimum mA value is ready to be programmed. The currently programmed minimum value is shown on the 3-DIGIT LCD.
- Enter the minimum mA input signal value. Note: this value must be less than the maximum mA input signal value. Press the FIELD button to select the digit to program. The digit will blink when selected. Press the DIGIT button to change the selected digit. Repeat until all digits are programmed.

Flow Verification System (FVS) – sensor sold separately
The A-100NV is equipped with a Flow Verification System which is designed to stop the pump and provide a contact closure output in the event the sensor does not detect chemical during pump operation. (This could indicate a clogged injection fitting, empty chemical solution tank, worn pump tube, loose tubing connection, etc.)
To allow the pump to clear any gasses that may have accumulated during stopped operation (such as with chlorine), an alarm delay time value from 1- 256 seconds must be programmed.
Press the FIELD and DIGIT buttons at the same time to enter the delay value.
Note: an alarm delay value of 000 disables the FVS system. Any other value (001-256) activates the FVS.
The pump will stop, and the alarm mode activated, if no pulses are received by the pump and the alarm delay time period has ended.
Press the STAND-BY button twice to clear the alarm and restart the pump. The Flow Verification Sensor is sold as an optional accessory.
Ensure the flow sensor used is operated within its operating flow range. Flows that fall outside of the sensors range will create a false no-flow alarm.
FAQs
Frequently Asked Questions
A-100NV Set-Up and Controls
- What is a 0-10V DC input signal?
The two most common analog signal types in modern industrial automation are 4-20mA and 0-10V.
0-10V
A 0-10V (or in some cases, 0-5V) analog signal uses voltage to represent a variable signal. It’s a simple method of analog signal transmission most commonly used in HVAC applications, but has some inherent disadvantages, including:
- A sensor fault (no signal) cannot be detected: A value of 0V can indicate either zero value or no signal. It’s possible to work around this by using a 2-10V instead, but this is uncommon.
- It is prone to electrical noise and interference.
- Over longer cable distances, voltage drop can cause an inaccurate signal.
- A separate power supply to the instrument is usually required, meaning the sensor requires at least three wires.
4-20mA
The 4-20mA current signal is much more common for analog signal transmission in a lot of applications. A current signal offers some real-world advantages, such as:
- A no signal fault can easily be detected: 0mA indicates no signal, while 4mA indicates a zero value.
- An instrument can be ‘loop-powered (often 24VDC) – mean it can be powered by the same cable that it transmits on, meaning only two wires are required.
- It is much less prone to electrical noise, interference and voltage drop.
- In addition, for many applications there is now a much wider range of 4-20mA instruments available than 0-10V.
How do I calculate Hz value to enter into programming?K-factor of device used (Blue-White's F2000 meter) x GPM divided by 60 = Hz
Does the pump have remote start stop connections?No, it does not. If that feature is required, the A1 and/or A2 series is suggested.
