Principles
Operating principle
MNS - Level controller using a discrete sensor
This product is designed to control a level by means of a discrete probe (float switch).
On power-up, the relay remains in the rest position. The level control function only begins after
the pushbutton (PB) is pressed. This pushbutton is located on the front of the product, but can
also be remotely located between Y1 and A1.
The output relay only closes if the float switch is open. If the level rises enough to make the float
switch close, the relay will be deactivated after the time delay Toff.
When the level drops and the probe opens, the relay is re-energised after the time delay Ton.
The LEDs flash when the product is energised but the cycle has not started (PB has not yet been
pressed).
The time delays Ton and Toff are set at between 0.1 and 10 sec by means of two potentiometers
on the front face.
