Notes:
• The connection of power or voltage sources of any type is not permitted.
• The source resistance for the outputs is of 3.3 k
Ω
. The input resistance for subsequent
signal inputs, e.g. optocouplers, must be greater than or equal to 47 k
Ω
.
• The function of the signal input (contact 1) depends on the operating mode that is set for
the pulsation (see chapter 3.2.2). With the operating mode “by hand key”, control is performed
statically, i.e. the ultrasonic operation is always activated under L status, and deactivated
under H status.
With all other operating modes, the input works as an edge-controlled changeover switch.
The input resistance totals approx. 50 k
Ω
.
• When connecting a changeover contact (toggle function) to connector 1, the make time
must be > 100 ms.
