Two capacitive proximity switches B113 (1) and B114 (2) are located on the side of
the lower tank B101 and mounted on a profile plate. The proximity switches can be
mechanically adjusted. The sensing distance through the tank wall can be adjusted
with a screw. The binary 24 V input signals are connected to the I/O-terminal XMA1.

Level monitoring with capacitive proximity switches B113 and B114
The minimum level of the tank B101 is indicated by the lower sensor B113. At
minimum level the heating element E104 should be totally immersed into the liquid.
The maximum level of the tank B101 is indicated by the upper sensor B114.
At reset position of the system both sensors have to be activated.
