Electrical connection
The electrical connection of the device must be carried out according to the respective country specific
standards. Incorrect installation or adjustment could cause applicationally conditioned risks.
Use only suitable cables with max. 25
per wire, that fulfills the requirements e.g. regarding temperature,
resistance or laying at the place of installation.
The cable gland is suitable for cable diameters from 4 to 10 mm. After installation of the cable the cable gland
must be fix screwed to ensure the tightness of the connection housing.
For inauguration it is suggested to switch off all connected control devices to avoid unintended control actions.
Version UB / UC with relay output
Power supply input, electrode circuit and the two relay outputs are safe galvanically isolated from each other.
Due to the integrated wide range power supply, for connection to supply voltages from 20...253V AC / DC, the
filling level limit switch is suitable for using in all common energy supply networks.
The connection is reverse polarity protected.
A fuse is integrated internally at the power supply circuit. Due to this the installation of a fine protection is not
necessary.
Inductive loads at the relay contacts, e.g. auxiliary contactors or magnetic vents may only be used with a free-
wheeling diode or a RC protection circuit to avoid high voltage peaks.
Version GA with PNP switching output
The power supply voltage and the PNP switching output are galvanically separated from the electrode circuit.
The power supply voltage may not exceed 27 V to avoid damage of the electronic.
The power supply voltage connection is polarity protected.
The load at the PNP switching output will be connected contactless and by this bounce-free to the positive
terminal of the power supply voltage by a semiconductor switch. At activated switching state a positive signal
near power supply voltage is produced at the terminal Out.
At deactivated switching state and at failure of power supply voltage the semiconductor switch is shut off.
The PNP switching output is current limited to 0,5 A.
Inductive loads at the PNP switching output, e.g. relays or contactors may only be used with a free-wheeling
diode or a RC protection circuit to avoid high voltage peaks.
