PES HF shield termination by PE connection through shield clamp
Note!
ƒ Switching of control signals:
– Use shielded cables
– HF shield termination by PE connection
– The minimum load for switching the signals through correctly is 12 V and
5 mA. Both values have to be exceeded at the same time.
ƒ Switching of mains potentials:
– Unshielded cables are sufficient
ƒ For the protection of the relay contacts a corresponding suppressor circuit is
absolutely required for an inductive or a capacitive load!
ƒ The service life of the relay depends on the type of load (ohmic, inductive or
capacitive) and the value of the switching capacity.
ƒ The output message can be changed with C0409.
ƒ If you use an application I/O function module:
– The relay K2 is only active with application I/O E82ZAFAC from version
Vx21 onwards.
