Maintenance
Step Eleven
GENERAL:
The Smart Trak™ with Compact Junction Box requires no periodic maintenance except cleaning as required. It
is the responsibility of the user to determine the appropriate maintenance schedule, based on the specific
characteristics of the application liquids.
CLEANING PROCEDURE:
1.
Power:
Make Sure that all power to the sensor, controller and/or power supply is completely disconnected.
2.
Sensor Removal:
Make sure that the tank is in a state where it is safe to remove the sensors. Carefully,
remove the Smart Trak™ from the installation.
3.
Cleaning the Sensor:
Use a soft bristle brush and mild detergent, carefully wash the Smart Trak™. Do not
use harsh abrasives such as steel wool or sandpaper, which might damage the surface sensor. Do not use
incompatible solvents which may damage the sensor's PP or Ryton plastic body.
4.
Sensor Installation:
Follow the appropriate steps of installation as outlined in the installation section of
this manual.
TESTING THE INSTALLATION:
1.
Power:
Turn on power to the switches and/or power supply.
2.
Immersing the switch:
Immerse the sensing tip of each switch in its application liquid, by filling the tank
up to the switches point of actuation. An alternate method of immersing the switch during preliminary
testing is to hold a cup filled with application liquid up to the switch's tip.
3.
Test:
With the switch being fluctuated between wet and dry states, the switch will open or close depending
on wiring status. If the system doesn't have an input indicator, use a voltmeter or ammeter to ensure that
the switch produces the correct signal.
4.
Point of actuation:
Observe the point at which the rising or falling fluid level causes the switch to changes
state, and adjust the installation of the switch if necessary.
