Description

The JSNY8 Safety Interlock Switch, in conjunction with the
machine 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 JSNY8 has 2 NC + 2 NC positive force disconnection
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 locking mechanism
moves 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 locked position when the solenoid (E1-E2)
is supplied with operating voltage. Release of the actuator key
is only possible when 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specicapplications.

Tamper-proof

The JSNY8 is tamper-proof. The safety device cannot be ma­nipulated by screwdrivers, magnets or other tools.

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.
