General description
Magne is an electromagnetic process lock that locks a door or hatch with a holding
force of up to 1500 N.
Magne 3 keeps a door locked to protect a process from unwanted interruptions. It
needs to be complemented by external interlocking devices if used in safety
applications.
Magne 4 has an integrated Eden sensor, which provides a high safety level of guard
interlocking protection. Magne 4 is available with built-in Adam DYN (DYNlink) or
Adam OSSD using an M12-5 or M12-8 connector.
Magne can be mounted on a door or a hatch with a JSM mounting kit, available for
either sliding doors or conventional doors (5–15 mm door gap). Y-connectors can be
used to connect several units. Magne 4 requires an Eva (which uses either a general or
unique code), an anchor plate “32B” (with built-in permanent magnet) or “32A”
(without permanent magnet) and a cellular rubber.

Installation
Warning! Magne shall be installed by a trained electrician following the Safety
regulations, standards and the Machinery directive. Installation shall be done in
accordance with a risk assessment for the individual application. Failure to comply
with instructions, operation that is not in accordance with the use prescribed in the
instructions, improper installation or handling of the device can affect the safety of
people and the plant.
Warning! All safety functions shall be tested before starting up the system.
Warning! Do not tamper or bypass the safety function. Failure can result in death
or serious injury.
Warning! The M12 connector shall be connected after Magne has been installed
on the intended surface.
Caution! Magne must be installed as close to the door handle as possible. The
distance between the lock and the handle creates a lever effect, reducing the holding
force.
Note! Do not connect Magne to power supply before Eva is within sensing
distance. The Adam sensor within Magne 4 needs to learn the Eva code. Make sure
that no power supply is connected when the cable is fitted to the Magne PIN out.
