1.4.4
Electromagnetic ambient conditions (EMC)
The device was tested to DIN EN 61326-1 for electromagnetic compatibility (EMC) and complies
with the requirements for class B devices according to EN 55011.
It is suitable for use in facilities and areas which are directly connected to a public low-voltage
supply network, e.g. medical laboratory facilities.
1.4.5
Remote operation
Several options are available for remote control and remote operation. Depending on
requirements, the most convenient solution may be selected.

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
.
