Powering On the A-100NFP
The A-100NFP is powered on when plugged into the power source. The pump is now ready to be run manually by switching on the Power Switch.
Controls
The A-100NFP has only a dial knob to control the speed (output) of the pump. Adjust the knob to the desired percentage of speed.
Flow Verification System (FVS) – sensor sold separately.
The A-100NFP 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 gas 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 sensor’s range will create a false no-flow alarm.
FAQs
Frequently Asked Questions
A-100NFP Set-Up and Controls
- What is a motor active open collector output?
An open collector output is a type of digital output that can be used to control devices that require a low voltage signal. The output is essentially a transistor that can be turned on or off to provide a low voltage signal. When the output is turned on, the transistor connects the output to ground, providing a low voltage signal. When the output is turned off, the transistor disconnects the output from ground, providing a high voltage signal.
The motor active open collector output has the output sink to DC ground when the motor is de-energized.
What is an alarm open collector output?An open collector output is a type of digital output that can be used to control devices that require a low voltage signal. The output is essentially a transistor that can be turned on or off to provide a low voltage signal. When the output is turned on, the transistor connects the output to ground, providing a low voltage signal. When the output is turned off, the transistor disconnects the output from ground, providing a high voltage signal.
Open collector outputs are often used in alarm systems to control devices. When an alarm is triggered, the open collector output is turned on, which activates the connected device. This allows the alarm system to control multiple devices with a single output.
Open collector outputs are also often used in industrial control systems to control devices such as motors, valves, and sensors. When a control signal is received, the open collector output is turned on, which activates the connected device. This allows the control system to control multiple devices with a single output.
