General Instructions on Equipment and Product Damage

3 General Instructions on Equipment and
Product Damage
Disconnecting connections while under voltage will destroy the electronic components
of the valve system!
Large differences in potential occur when disconnecting connections under voltage, which can
destroy the valve system.
Make sure the relevant system component is not under voltage before assembling the valve
system or when connecting and disconnecting it electrically.
An address change will not be effective during operation!
The bus coupler will continue to work with the previous address.
Never change the address during operation.
Disconnect the bus coupler from the power supply UL before changing the positions
of switches S1 and S2.
Malfunctions in the fieldbus communication due to incorrect or insufficient grounding!
Connected components receive incorrect or no signals. Make sure that the ground connections
of all valve system components are linked
– to each other
– and to ground
with electrically conductive connections.
Verify proper contact between the valve system and ground.
Malfunctions in the fieldbus communication due improperly laid communication lines!
Connected components receive incorrect or no signals.
Lay the communication lines within buildings. If you lay the communication lines outside
of buildings, the lines laid outside must not exceed 42 m.
The valve system contains electronic components that are sensitive to electrostatic discharge
(ESD)!
If the electrical components are touched by persons or objects, this may lead to an electrostatic
discharge that could damage or destroy the components of the valve system.
Ground the components to prevent electrostatic charging of the valve system.
Use wrist and shoe grounding straps, if necessary, when working on the valve system.
