11.0 TFD (Tube Failure Detection)
Flex-Pro is equipped with a Tube Failure Detection System which is designed to
stop the pump and provide an output alarm (see Output menu) in the event pump
the tube should rupture and chemical enters the pump head. The 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 the presence of a large number of
chemicals including Sodium 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 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 output (if configured), and
screen will flash TFD with an alarm icon.
Confirm Chemical Detection - To determine if your chemical will be detected by
the system, remove the pump head cover and the pump tube and roller assem-
bly. Place a small amount of chemical in the bottom of the pump head - just
enough to cover the sensors. Replace the pump head cover only. When asked if
the tube was replaced, select “no” and press enter. Turn on the pump (press
start). If the TFD system detects the chemical, the pump will stop after a two
second confirmation period and the TFD Alarm screen will 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 the chemical from sensor probes. Replace the roller
assembly and tubing. Replace the pump head cover. Press the START button to
clear the alarm condition and restart the pump.

10.0 Pump Tube Timer
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 START button
repeatedly until the Tube Timer screen appears. Screen will display current Pump
Tube Time in run-time hours. The Tube Timer screen will display for 4 seconds and
then switch back to the previous operating display screen.
While displayed, press DOWN arrow 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.
12.0 Alarm Relay
Pump has a built in 6 amp alarm output relay. Relay is pre-configured to
energize on tube failure detection (TFD) and on Flow Verification Sensor (FVS).
A Flow Verification Sensor must be installed and configured for relay to trigger
on no-flow conditions.
