Function/block diagram
The CU4plus AS-i control unit is a slave for the fieldbus system
AS-Interface according to specification V3.0. The profile is S-7.A.*.E
(3 outputs and 2/4 inputs).
The CU4plus AS-i is designed for the extended address range.
With these devices in the extended address range up to 62 slaves
(formerly known as 2.1) can be connected with one AS-Interface
cable.
Attention:
Consider cumulative power input and simultaneity factor!
With the CU4plus AS-i energy supply of the control valves can be
effected via the AS-i bus or via separate auxiliary energy lines.
Thus, it is possible to realize an EMERGENCY STOP function: If
the auxiliary voltage is safely shut off by conventional means, the
control valves are deprived of electric energy and they fall into
a safe position. The function of the inputs is preserved even if
auxiliary energy is shut off.
The control of the solenoid valves is undertaken in energy-saving
mode via the pwm signals.
