Electrical connection
Attention
Before connection, check whether the mains voltage required by the control unit of the
JUDO JRSF automatic backwashing protection filter matches the local circumstances!
The internal electrical connection of the JUDO JRSF automatic backwashing protection
filter must only be performed by JUDO customer service or authorised technical
personnel!
The electrical connection can only be made when the system is in a voltage-free state!
Only potential-free NOC contacts may be connected at the inputs, under no
circumstances may external voltage be connected!
The linear drive may only be connected to or disconnected from the control unit in a
zero-volts state; failure to observe this may result in malfunctions!
JUDO Wasseraufbereitung GmbH will not be responsible for the resulting damage.
All risks are borne solely by the operator!
The mains connection cable with mains plug, the connecting cable with 8-pole coupling
plug for the linear drive and the connecting cable of the solenoid valve are connected to
the control unit in the factory!
If necessary the connecting cable of the differential pressure gauge must be correctly
extended by the customer!
To trigger an external backwashing the EX input must be connected for at least 3
seconds!
See the separate circuit diagram for information on the electrical connections, terminal
assignments and cascade operation.
