Topographic
Equalizing Device (TED)
This is an adjustable unit that
prevents emptying/draining of command tubes at the end of control on
slopes.
Operation Insructions
- Free the calibration screw until the spring
is free.
- Disconnect the command tube from the valve
and send a water command to
the valve.
- Wait until the air is drained from the tube
and water begins to flow.
- Reconnect the command tube to the valve.
- Close the calibration screw 2/3 of it's
length.
- Stop the water command to the valve.
- Free the calibration screw slightly until a
few drops of water go out of the tube.
- Check if the valve has changed its
condition. If not, free the calibration screw a bit more until the
valve changes its condition.
- Tighten the nut of the calibration screw,
and the TED is calibrated.
