INSTALLATION
IM14229-5
GB
1) The valve must only be supplied with 24V DC ±10% and a max. ripple of 10% (no supply via diode bridge). Overvolt-
age or a ripple rate exceeding these tolerances can damage the electronics.
2) The max. current at the digital output is 200 mA/4.8W (PNP output). The output is protected against short circuit and
overload.
3) If a relay (inductive load) is connected to the pressure switch output, a freewheel diode or a varistor must be used.
4) A shielded cable must be used for protection against interference and EMC.
5) The valve body must be grounded with the earthing terminal PE (dia. M4)
