Notes:
• The inputs and outputs may not be connected to other circuits, ground planes,
or ground terminals.
• The connection of power or voltage sources of any type is not permitted.
• The source resistance for the outputs is of 2.2 k
Ω
. The input resistance for subsequent signal
inputs, e.g. optocouplers, must be greater than 20 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 ultrasonic 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.
• When connecting a changeover contact (toggle function) to connector 1, the make time must be
> 100 ms.
Please note:
Proper operation will depend on the length of the connection cable. If an extension is used,
a length of 3 m may not be exceeded.
1.4.4 Electromagnetic compatibility (EMC)
The device has been checked for electromagnetic compatibility in accordance with
DIN EN 61326-1 and meets the requirements for Class B devices in accordance with EN 55011.
It is suitable for use in institutions and other areas that are directly connected to a public
low-voltage power supply, e.g., medical laboratory facilities.
