Unlocking using a special tool
Locking / unlocking using an electromagnet
Power supply for the electromagnet on 83 893 2
The electromagnet for type 83 893 2 safety switches is supplied by an
electronic circuit which increases its service life. As the 24 V version is
protected by a bridge rectifier, an A.C. or D.C. supply can be used.

Other information
Type 83 893 2 safety switches are supplied with a tool (1) which can
be used to unlock the moving guard, bypassing the electromagnet.
Unlocking using a tool is recommended in the following cases:
• machine maintenance (if the tool is in the “UNLOCK” position 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 tool. The “NC” contact is integrated in the machine
safety circuit.
Type 83 893 2 safety switches are fitted with an electromagnet for
locking/unlocking the guard.
With the guard locked, the force required to remove the key is 50 daN.
In addition to the 2-pole contact element actuated by the key, type 83 893
2 limit switches also have a positive break type “NC” contact element,
actuated by the electromagnet.
The “NC” contact is integrated in the machine safety circuit.
(1) Auxiliary contact
E1-E2: Power supply for electromagnet
13-14: Safety contact for redundancy or signalling
The 120 V and 230 V versions are A.C. only.
It is also protected against voltage surges.
Category 1 connection according to EN 954-1
