11.7.2 Float switch, lateral installation
The float switch is designed for installation in a 10 l tank. The float switch opens when the maximum liquid
level in the tank is exceeded and switches off the pumps via the relay.
Prerequisites
– The tank is mounted
– Electrical connection of the float switch is established
– Power supply unit switched on.
Procedure
1. The float switch with cable is led from the inside through the upper left opening in the tank and screwed
from the outside. The float must be mounted to swivel upward.
2. Connect the float switch. The switch must emit a signal when there is no liquid.
3. Fill the tank and determine if the float switch interrupts the signal when the maximum fill level is
exceeded. The float must move upward.
4. Check the positioning and adjustment of the sensor by repeated filling and emptying.
Note
Make sure that the float always moves freely and does not jam due to dirt.
