It is recommended to leave default setting at 75% sensitivity. This will
eliminate your chance of false triggers.
Only increase sensitivity if the solution your pumping does not trigger the
TFD alarm at 75% sensitivity.
14.0 TFD (Tube Failure Detection)
Flex-Pro is equipped with a Tube Failure Detection System which is designed to
stop pump and provide an output alarm (see Output menu) in the event pump
tube should rupture and chemical enters pump head. This patented system is
capable of detecting presence of a large number of chemicals including Sodium
Hypochlorite (Chlorine), Hydrochloric (muriatic) Acid, Sodium Hydroxide, and
many others. System will not be triggered by water (rain, condensation, etc.) or
silicone oil (roller and tubing lubricant).
If system has detected chemical, pump tube must be replaced and pump head
and roller assembly must be thoroughly cleaned. Failure to clean the roller
assembly will void warranty.
If TFD alarm occurs, pump will stop, close an alarm outputl (if configured), and
screen will flash TFD with an alarm icon.
Confirm Chemical Detection - To determine if your chemical will be detected by
system, remove pump tube and roller assembly. Place a small amount of
chemical in bottom of pump head - just enough to cover sensors. Turn on pump.
If TFD system detects chemical, pump will stop after a two second confirmation
period and TFD Alarm screen will display. If TFD system does not detect chemi-
cal, pump will continue to run after confirmation period. Carefully clean chemical
out of pump head being sure to remove all traces of chemical from sensor
probes. Press START button to clear alarm condition and restart pump.
