JSNY9 -
safety interlock switch
The control unit offers
eight operating positions
that provide the actuator
with eight different input
options.
Standard key.
Description
The JSNY9 is used for locking a gate/hatch, to prevent access to
machinery, until hazardous operations have ceased.
Applications include:
• processes which cannot be interrupted, e.g. welding.
• machinery with a long stopping time, e.g. paper machinery
which requires a long braking operation.
• prevention of unauthorised access to a particular area.
The JSNY9 is equipped with a 2 x (1NO +1 NC) contact
configuration, the first pair of contacts changeover when the key
is inserted. The second pair of contacts changeover when the
locking mechanism is in the locked position.
The JSNY9 switch is encased in a robust plastic housing and can
be mounted either horizontally or vertically. The advanced design
of the head provides eight possible key insertion options, this is
achieved by mounting the head either vertically or horizontally on
the base unit, as shown in the diagram. The location for the actuator
key is reinforced and bevelled to ensure a smooth operation.
Two versions
The JSNY9 switch is available in two basic versions, either with a
spring lock or an electro-magnetic locking mechanism.
The JSNY9S (spring lock) switch operates immediately when
the gate/hatch is closed, i.e. when the key actuator is inserted into
the locking mechanism. The gate/hatch can be opened and the
actuator key released only by supplying the operational voltage to
the solenoid connections (E1 E2). The JSNY9S also has a manual
emergency unlocking facility to enable authorised release of the
actuator key.
In the JSNY9M (magnetic lock) version, the mechanism is only
locked when the gate/hatch is closed i.e. the actuator key inserted
and the solenoid (E1 E2) supplied with the operating voltage. The
gate/hatch can only be opened when this operating voltage is
removed
Optional features
The following optional features are available:
• LED display, indicating the status of the actuator key,
locking mechanism and contacts.
• Actuator to operate at smaller radii.
• Customer specific applications.
Safety level
In order to achieve a high safety level, the JSNY9 switch is equipped
with dual sets of contacts operated with a coded actuator key . In
order to meet the required installation safety level it is recommended
that the JSNY9 safety switch is monitored by an appropriate
ABB Jokab Safety safety relay. To obtain the same level of safety
as Eden, two switches per gate are required.
