5.2.1 Design
The LC 221 level controller incorporates the necessary
components to control and protect the pumps, such as relays and
capacitors for single-phase motors, contactors and additional
motor-protective circuit breaker for three-phase motors
(> Multilift M22).
The control panel offers a user interface with operating buttons
and a display for indication of operating conditions and fault
indications.
Furthermore, it has an integrated piezoresistive pressure sensor
which is activated by compressed air directly via the pressure
tube inside the collecting tank. Finally, it has terminals for power
supply, connection to the pump and the inputs and outputs
mentioned in section 5.2 LC 221 controller.
The front cover is closed by four bayonet fastenings with quarter
turn locks. On the left side, the locks are extended and connected
to the cabinet bottom with hinge strings. The cabinet offers the
possibility of being mounted on a wall without opening it first.
A drilling template and six screws with rubber guides are
enclosed.
