Tele CLH3X level monitoring relay for conductive fluids 230VAC, SPDT 5A 250V contacts

The level monitoring relay CLH can be used with conductive fluids to control filling and emptying, depending on the position of the function selector switch. This switch is on the front panel. A potentiometer can be used for infinitely variable control sensitivity between 10...70kOhm. The earth probe (E3) may also be connected to the container, provided it conducts and is earthed.

Function selection switch in position "down":
The output relay responds after the set time delay (approx 2s) when the maximum probe (E1) is wetted. This status is also signaled by the yellow LED. The output relay will release after the fixed time delay (approx 2s) and the LED switch off only when the level falls bellow the minimum probe.

Function selection switch in position "up":
the output relay responds after the set time delay (approx 2s) when the level falls bellow the minimum probe (E2). This status is also signaled by the yellow LED. The output relay will release after the fixed time delay (approx 2s) and the LED switch off only when the maximum probe (E1) is wetted.
