Devices
Solenoids with plug connector according to DIN EN 175301-803
can be used as actuating solenoids for valves with solenoid end sleeve diameter 9 mm.
Refer to the following table for the solenoid specifications.
Explosion protection
The valve actuating solenoids can be used
- in Zone 2 areas at risk of gas explosion. They comply with Category II3G and have ignition protection class
EEx nA II T5.
- in Zone 22 areas with inflammable dust. They comply with Category II3D and have protection class IP 65.
Maximum surface temperature is T = 95 °C.
Installation
It is imperative that the appropriate Ex regulations are observed during installation, maintenance or repair, in
particular EN 60079-14 and EN 50281-1-2.
Electrical installation must be carried out under additional observation of all respective national regulations (in
Germany, VDE 0100) by a qualified electrician or under the supervision thereof.
Before installation, the specifications of the device identification are to be compared with the intended operating
conditions to ensure proper usage.
Usage, assembly, commissioning, maintenance
Valve actuating solenoids are electrical components. They cannot be used without the associated valve.
Valve-solenoid combinations are generally supplied fully assembled and tested. When replacing/changing
solenoids, it must be ensured that the combination is approved with a Norgren-Herion valve and that the
solenoid is properly fixed to the valve. The solenoid can be clamped when positioned offset by 90°; the
permissible tightening torque for the fixing nut is 0.5 Nm.
The solenoids are maintenance-free. If faults or failures with an unknown cause occur during operation, the
solenoids must be replaced. Defective coils or other electrical or electronic components cannot be repaired or
replaced.
Obviously damaged solenoids must not be installed or must be replaced.
Solenoids must not be used as a lever arm.
Special protective measures are required if the solenoids are subjected to particular kinds of extreme loads.
Electrical connection
Circuit diagram (DC and AC)
The solenoids are fitted with a tested plug connector complying with DIN EN 175 301-803 with special closure
(M3 Allen key required). The cable is connected to the screw terminals after removing the socket insert. It is not
necessary to observe the polarity. The protective conductor must always be connected.
The terminals are designed for cross-sections up to 1.5 mm
Only the supplied cable sockets may be used. The device loses the Ex approval if other cable sockets are used.
