OUTPUT ADJUSTMENT
The speed of the pumping mechanism is adjustable from 0.5 to 100 % motor speed (0.03 RPM to 65 RPM).
10.0 TUBE FAILURE DETECTION (TFD+)
The pump is equipped with a Enhanced Tube Failure Detection (TFD+) system,
which is designed to stop the pump and provide an output alarm in the event
the pump tube should rupture, and a chemical enters the pump head.
This TFD+ system can detect the presence of many chemicals, including
sodium hypochlorite (chlorine), hydrochloric (muriatic) acid, sodium hydroxide,
oils based polymers, water based polyers, and many others. The system will
not be triggered by water (rain, condensation, etc.) or silicone oil (roller lubri-
cant).
NOTE
: If the system has detected a chemical, the pump tube must be
replaced, and the pump head and roller assembly must be thoroughly
cleaned. Failure to clean the roller assembly will void the warranty.
NOTE
: If the TFD+ alarm is triggered, the pump will stop, and close an alarm
output.

10.1 Confirming Chemical Detection
To determine if a chemical will be detected by the system:
1. Remove the pump head cover, and the pump tube and roller assembly.
2. Place a small amount of chemical in the bottom of the pump head that is enough to cover the sensors.
3. Reinstall
only
the pump head cover.
4. Turn on the pump by pressing the START button.
NOTE
: If the TFD+ system
detects
a chemical, the pump will stop after a two-second confirmation period.
NOTE
: If the TFD+ system
does not detect
a chemical, the pump will continue to operate after the
confirmation period.
5. Carefully clean the chemical out of the pump head. Ensure to remove all the chemical traces from the sensor
probes.
6. Reinstall the roller assembly and tubing.
7. Reinstall the pump head cover.
8. Press the START button to clear the alarm condition.
9. Restart the pump.
