Locking / unlocking using an electromagnet
Locking using a key on 83 894 1
Power supply for the electromagnet on 83 894 1
The electromagnet for type 83 894 1 safety switches runs on D.C. and is
therefore particularly reliable.
Connections
Category 1 according to EN 954-1
Examples of wiring diagrams with a fuse to provide protection against
short-circuits in the cable or tampering.

Other information
Type 83 894 1 safety switches are supplied with a key-operated lock
which can be used to unlock the moving guard, bypassing the
electromagnet.
Unlocking using a key-operated lock is recommended in the following
cases :
• machine maintenance (if the key is turned to “UNLOCK” and then
removed, this will prevent the machine from restarting accidentally,
therefore ensuring the safety of maintenance personnel),
• mains failure,
• problem with unlocking (locking cannot be released: fail-safe condition).
Unlocking by applying voltage to the electromagnet always takes priority
over unlocking using a key-operated lock.
The locking mechanism for standard devices allows the key to be removed
in the “LOCK” and “UNLOCK” positions.
Type 83 894 1 safety switches are fitted with an electromagnet for
locking/unlocking the guard.
With the guard locked, the force required to remove the key is 200 daN.
In addition to the 3-pole contact element actuated by the key, 83 894 1 limit
switches also have a positive break type “NC + NO” contact element,
actuated by the electromagnet. The NC contact is integrated in the
machine safety circuit, and the NO contact indicates the position of the
electromagnet.
As it is protected by a bridge rectifier, A.C or D.C supplies can be used
(24 V, 48 V, 120 V or 230 V).
It is also protected against voltage surges.
Category 3 according to EN 954-1
Examples of wiring diagrams with redundancy of the switch contacts,
without monitoring.
