Confirm the FVS flow range - The Flow
Verification Sensor (FVS) will only function
within its operating range. Sensor model FV-
100-6V has an operating range of 30-300
ml/min (1-10 oz/min). If the pump’s output is
less than 30 ml/min (0.5 ml/sec), the sensor
will not detect chemical and a signal will not
be sent to the pump.

Install the FVS Flow Sensor - The Flow Verification Sensor (FVS) should
be installed on the inlet (suction) side of the pump tube. The sensor includes
a PVC tubing insert, located inside the sensor’s female thread connection,
that is designed to seal the sensor onto the pump tube inlet adapter. Thread
the sensor onto the pump tube until the tubing insert is snug against the
pump tube inlet fitting - do not over-tighten.
Connect the red/white, black, and white wires from the sensor to the red,
black, and yellow wires located in the pump’s junction box. See page 7.
Contact Closure Alarm Output - A contact closure output (relay) is
provided with the FVS system. The relay can be configured for normally
open (factory default) or normally closed operation by properly positioning
the connector plug on the circuit board (see page 7).

(FVS) Flow Verification System
The A-100NE 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
stopper operation (such as with chlorine), an alarm delay time value from 1-
256 seconds must be programmed (An alarm delay value of 000 seconds
disables the FVS system). 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.

TFD (Tube Failure Detection) -
Tube Failure Detection System which is designed to stop the pump and
provide a contact closure output in the event the pump tube should rupture
and chemical enters the pump head. This patented system is capable of
detecting the presence of a large number of chemicals including Sodium

Tubing failure
Hypochlorite (Chlorine), Hydrochloric
(muriatic) Acid, Sodium Hydroxide, and
many others. The system will not be
triggered by water (rain, condensation, etc.)
or silicone oil (roller and tubing lubricant).
If the system has detected chemical, the
pump tube must be replaced and the pump
head and roller assembly must be
thoroughly cleaned.
Confirm Chemical Detection - To determine if your chemical will be
detected by the system, remove the pump tube and roller assembly. Place a
small amount of the chemical in the bottom of the pump head - just enough
to cover the sensors. Turn on the pump. If the TFD system detects the
chemical, the pump will stop after a five second confirmation period and
the ALARM icon will light on the display. If the TFD system does not
detect the chemical, the pump will continue to run after the confirmation
period. Carefully clean the chemical out of the pump head being sure to
remove all traces of chemical from the sensor probes. Press the
RUN/STAND-BY button to clear the alarm condition and restart the pump.
Contact Closure Alarm Output - A contact closure output (relay) is
provided with the TFD system. The relay can be configured for normally
open (factory default) or normally closed operation by properly positioning
the connector plug on the circuit board (see page 7).
This Shroud is designed to weather proof this Peristaltic Pump. If the
pump is wall mounted the shroud is not necessary and will still be
considered weather proof.
