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 mode of operation that is set for
the pulsation (see chapter 3.2.2). With the operating mode "by hand key", control is conducted
statically, i.e. the ultrasound operation is always activated under L status, and deactivated under
H status.
With all other modes of operation, the input works as an edge-controlled changeover switch.
The input resistance measures approx. 50 k
Ω
.
• When connecting a changeover contact (toggle function) to connector 1, the make time
must be > 100 ms.
b) RS 232 interface connection
The RS 232 interface connection is located on the rear side of the HF generator.
For connection and communication purposes, a standard serial conductor (RS 232) can be
used. Implementation of the technical programs required for communication is the responsibility
of the operator and is not supported by the manufacturer. The manufacturer only guarantees
the proper functioning of the interface.
The instruction set for the RS-232 interface will be made available by the manufacturer free of
charge, upon request.
Important:
Proper operation will depend on the length of the connection cable. If an extension is used, a
length of 5 m may not be exceeded.
Caution
The inputs and outputs of the remote control connector and RS-232 interface may only be
connected with devices of protection class I that are connected to the same mains supply circuit.
