With capacitive load, connecting cables longer than 50m or
connection to a PLC with capacitive input circuit, a 22Ω resi-
stor is required to be connected in series to limit current
spikes.
Warning!
Overloading the magnetic switches may lead to the destruc-
tion of the reed switch, which may cause a malfunction to
the control circuitry and harm to persons or goods. The ma-
ximum switch capacity values given on the tag label must
not be exceeded.
Level Transmitter (only Typ BMG)
The level transmitter must be connected according to the
wiring diagram printed on the transmitter and wired to the
electronic evaluation unit in series.
A screened cable must be used and earthed at one end for
long lines or if the cables are laid together with power
cables.
