JSNY8 -
safety interlock switch
Description
The JSNY8Safety InterlockSwitch, inconjunctionwith themachine
control system, enables gates/movable guards etc to be locked
in their protective positions, thus preventing access to machinery
until dangerous operations have ceased.
Applications include:
• processes which cannot be interrupted, such as welding.
• machinery with a long stopping procedure, such as paper
machinery that requires a long braking operation.
• prevention of unauthorised access to a particular area.
The JSNY8has 2NC+2NC positive forcedisconnection contacts.
The first pair closes when the actuator key is pushed into the
head. The other pair closes when the locking mechanism is in
the locked position. The head can be set in four positions, thus
providing the safety device with four different operating positions.
These are selected by twisting the head as shown in the diagram
above. The leading edges of the actuator key are reinforced and
bevelled in order to guide it properly into the hole. The JSNY8 is
encased in a robust metal housing (IP67) providing a high level of
protection to the internal operating components.
Two versions
The JSNY8 is available in two basic versions, either with a spring
lock or a magnetic lock.
In the spring lock (JSNY8S) version, the lockingmechanismmoves
into the locked position directly when the door is closed and the
actuator key is pushed into the lock. The actuator key can only
be released and the gate opened by supplying operational voltage
to the solenoid (E1-E2).
The JSNY8S also has a emergency ’unlocking’ facility to enable
the actuator key to be released without the energisation of the
solenoid (E1-E2).
In the magnetic lock (JSNY8M) version, the locking mechanism is
only in the lockedpositionwhen the solenoid (E1-E2) is suppliedwith
operating voltage. Releaseof the actuator key is only possiblewhen
the operating voltage is removed from the solenoid (E1-E2).
Optional features
The following optional features are available:
• actuator to operate at smaller radius.
• customer specific applications.
Safety level
The JSNY8 has double forced disconnection contacts to the
actuator key and the locking mechanism. The actuator key has
a triple coding design. To achieve maximum safety level in the
connection to the machine’s control system, it is recommended
that the JSNY8 is monitored by an appropriate ABB Jokab Safety
safety relay, Pluto safety-PLC or Vital. To obtain the same level of
safety as Eden, two switches per gate are required.
Regulations & standards
The JSNY8 is designed and approved in accordance with
appropriate directives and standards. See technical data.
