13.0 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 in event pump tube should rupture and
chemical enters pump head. Pump will detect a chemical with a conductivity
reading greater than 500 microsiemens. Chemicals with a conductivity of less
than 500 microsiemens will not be detected.
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).
Chemical from tube failure
Flex-Pro has a built in Pump Tube Timer. Timer starts when rotor is rotating and stops when rotor is idle.
To view current Pump Tube Timer value, press and hold START button, then press and release DOWN arrow.
Tube Timer screen will appear. Screen will display current Pump Tube Time in run-time hours. Tube Timer screen
will display for 4 seconds and then switch back to previous operating display screen.
While displayed, press START button twice to reset Pump Tube Timer to zero.
When replacing pump tube, pump will ask you if you’d like to reset Pump Tube Timer. If you choose YES, screen
will display current Pump Tube Time for 5 seconds before timer is reset to zero.
If system has detected chemical, pump tube must be replaced and pump head and roller assembly must be
thoroughly cleaned. Failure to clean roller assembly will void warranty.
If TFD alarm occurs, pump will stop, close an alarm output, and screen will flash TFD with an alarm icon.
Confirm Chemical Detection
To determine if your chemical will be detected by system, remove pump head cover and pump tube and roller
assembly.
Place a small amount of chemical in bottom of pump head - just enough to cover sensors. Replace pump head
cover only.
Turn on pump (press START). 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 chemical, 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.
Replace roller assembly and tubing. Replace pump head cover. Press START button to clear alarm condition and
restart pump.
