Intended use
The conductive control level relay L-ED 5 with the conductive probes is used to control 5 levels or to keep between 2 points the level of conductive liquids like water, oil, chemical products, etc., in tanks, deposits, recipients, tubes, etc.
Conductive probes could be supplied under request.
Function
The conductive level indicator L-ED 5 bases its work in the conductivity of the liquids to control. They have 5 function LEDs associated with a relay. They can work independently or related.
It is necessary an electrode or a probe for each level and a common electrode. If the tank is conductive, it could be used as the common electrode.
The relay operates when the liquid reaches any level electrode probe and illuminates its LED channel. The relay releases pressing RESET button. If the RESET button is pressed meanwhile the liquid covers a probe, the relay releases and will be activated when the button wil be unpressed.
If the RESET button is pressed meanwhile there are two or more active channels, the relay will not be disengaged until all channels will be inactive.
If there is no supply meanwhile the liquid covers any probe, the relay releases and the LED switch off, turning back when it will be supply.
Mechanical connection
It is simple: the device has to be installed in a DIN rail using the undecal socket. The connection of the probe/s depends on each application and the requested models of the probes.
