The voltage transformer supplies the circuit board with 24V. Compe-
nents running with 24V are supplied via the circuit boards.
The current consumption by the controller is limited to a maximum of
2.5 A by the integral fuse.
The sensors are connected to the terminal block. The terminal block
is connected to the circuit board and sends the sensor data to the
circuit board.
The terminal block is prewired. Only the wiring of the power supply
has to be filled ex-works. Further details are shown on the wiring
scheme of the HIU.
The controller is operated using a human machine interface (HMI)
that is connected to the LAN socket. The HMI is operated using the
buttons. A number of buttons perform a different function when they
are pressed and held (for more than 2 seconds). The HMI is used to
display the data. Data is only saved to the circuit board.
