JSNY5 -
safety interlock switch
Switch operational description
JSNY5 offers three contacts which gives both the two contacts
needed for high safety level as well as a contact for the indication
of operating status.
The advanced design offers the choice of four operating posi-
tions from only two actuator entries by simply rotating the head
through 180
o
.
However, when installed and in it's working condition only one
entry can be used, ensuring no other element can tamper with
the switch function.
When mounting the switch from the front two elongated holes are
provided to aid alignment with two set screw holes for accurate
fixing. Top fixing is also possible.
Three cable entries allow for a variety of cabling options including
through wiring.
Positive forced disconnected
contacts
The design assures that the contacts will not fail or be held in a
normally closed position, due to failure of the spring mechanism
or the welding/sticking of the contacts.
Protection from unauthorised or
incidental access
Toavoidunauthorisedoperation the JSNY5 switch ismanufactured
using multicoding to GS-ET 15. The switch cannot be defeated
by screwdrivers, magnets or any other mechanism.
After opening the snap-on cover, the head portion can be removed (version A), after
turning the head through 180
0
(version B) it can be replaced onto the body of the
switch and be locked into position by closing the snap-on cover. This ensures 4
actuating positions are possible.
Safety level
The positive forced disconnect contacts gives a high safety level.
By combining the JSNY 5 with one of our suitable safety relays
as for example from the RT-series, the safety PLC Pluto or Vital
(Tina) the requirements for both hatch and gate switch supervision
can be fulfilled. To obtain the same level of safety as Eden, two
switches per gate are required.
Regulations and Standards
The JSNY5 is designed and approved in accordance with
appropriate directives and standards. See technical data
