ABB Magne 3 Safety Sensors Switches And Locks
Product Information
The Magne 3 and 4 are electromagnetic process locks designed to lock doors or
hatches in applications where interruptions are unwanted. The Magne lock has a
holding force of up to 1500 N. It can be installed on both sliding doors and
hinged (conventional) doors using an ABB mounting kit.
Magne 3 keeps a door locked and should be complemented with an external
interlocking device for safety applications. Magne 4 has an integrated Adam
sensor that provides an interlocking function together with an Eva actuator,
which needs to be ordered and installed separately.
Product Usage Instructions
- Install the Magne and accessories as close to the door handle as possible. Use the relevant mounting kit and follow the installation guide included in the kit.
- For sliding doors, follow the installation tolerances for Magne 3 and JSM D23C provided in the installation guide.
- Anchor plate (B) should be installed with cellular rubber (C) between the anchor plate and the bracket (G) mounted on the door. Use suitable M8 screw (F) to adjust the anchor plate. Do not compress the cellular rubber to a thickness less than 8 mm and avoid overtightening the screw, as it may deform the anchor plate and reduce holding force.
- Make sure that the surfaces of the electromagnet (A) and the anchor plate (B) are completely parallel, ensuring full contact when the door is closed.
- Depending on the model, use the appropriate M12 5-pole or M12 8-pole connector for connections. The color coding and functions of each pin are as follows
| M12 5-pole connector | M12 8-pole connector |
|---|---|
| Brown: Locking signal +24 VDC | White: DYNlink signal in |
| White: Not used | Brown: +24 VDC |
| Blue: 0 V | Green: Locking signal +24 VDC |
| Black: Not used | Yellow: 0 V |
| Grey: Info output, locked | Grey: Info output (Adam and Eva closed & |
Magne
locked)
| Pink: DYNlink signal out (or OSSD2 out)
| Blue: 0 V
| Red: Locking signal +24 VDC (or Not used)
Note
- Y-connectors and other accessories are available to facilitate connection in series.
- Always use shielded cables to connect the unit to the rest of the safety circuit.
- The info output is non-failsafe and should never be used to control a safety application.
Product description
- Magne is an electromagnetic process lock that locks a door or a hatch and is intended for applications that are sensitive to unintentional or unnecessary interruptions. Magne has a holding force of up to 1500 N.
- Magne can be installed on a door, preferably using an ABB mounting kit, available for sliding doors or hinged (conventional) doors.
- Magne 3 keeps a door locked. If used in safety applications, Magne 3 needs to be complemented with an external interlocking device.
- Magne 4 has an integrated Adam sensor which provides an interlocking function together with an Eva actuator. The Eva actuator is ordered and installed separately.
- Magne 4 is available with integrated Adam DYN (DYNlink signal) or Adam OSSD (OSSD signal) using M12 5-pole or M12 8-pole connector.
- Anchor plates are delivered with a cellular rubber. Anchor plate 32E has an integrated permanent magnet. Anchor plate 32D is without a magnet. Y-connectors and other accessories are available to facilitate connection in series.

the safety circuit.
Warning! The info output is non-failsafe and shall never be used to
control a safety application.
Warning! The DYNlink signal or OSSD signals are used to control the
safety application.
Note! Several Magne 3X units can be connected using a M12-3A Y-connector or several Magne 4 OSSD-Info using a M12-3G Y-connector, but the info-signal will not be available. Several Magne 4X DYN units can be connected using a M12-3S Y-conector.
Safety precautions
Warning! Carefully read through the entire product manual before using
the device.
Warning! The devices shall be installed by authorized personnel following
the Safety regulations, standards and the Machinery directive.
Warning! 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.
Installation
Installation shall be done in accordance with a risk assessment for the
individual application.
Warning! All safety functions shall be tested before starting up the
system.
Warning! Do not defeat, 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 shall 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.
-
Install Magne and accessories as close to the door handle as possible. Use relevant mounting kit and follow the installation guide included in the kit. Installation tolerances for Magne 3 and JSM D23C on a sliding door
- A. Magne
- B. Anchor plate
- C. Cellular rubber
- D. Sliding door
- E. Fence
- X. 60 mm
- Y. 69 mm ±5
- Z. 18 mm ±5
-
Anchor plate (B) is installed with cellular rubber (C) between the anchor plate and the bracket (G) mounted on the door. The cellular rubber is attached to the anchor plate with adhesive tape and enables the anchor plate to adjust to Magne. Use suitable M8 screw (F). Recommended tightening torque is 7 Nm ±2.
Note! Do not compress the cellular rubber to a thickness less than 8 mm. Do not overtighten the screw. This can deform the anchor plate, causing reduced or no holding force. Make sure the surfaces of the electromagnet (A) and the anchor plate (B) are completely parallel, i.e. that full contact is obtained when the door is closed.
Installation tolerances- X. ±3 mm sideways
- Y. ±5 mm lengthways
-
The safety functionality of Magne 4 is based on the integrated Adam sensor and the Eva actuator. Eva unit (A) must be correctly positioned above the yellow cover on Magne/Adam (B) when the door is closed.
Positioning tolerances- X. ±5 mm sideways
- Y. ±5 mm lengthways
- Z. 2-7 mm Note! For the sensor to work as intended it is very important that the units are correctly positioned and that the safety functions are tested.
-
Connect the pin out according to chapter ‘Connections’.
-
Connect the M12 connector to Magne.
Note! Make sure no power supply is connected when cable is fitted to the Magne M12 pin out. -
Close the door to put Eva within sensing distance of Adam.
-
Connect Magne to the power supply and turn power on.
Note! Only connect Magne to power supply when Eva is within sensing distance. The integrated Adam sensor in Magne 4 needs to learn the Eva code. For Magne 3 the blue LED will illuminate with a solid light when connected. For Magne 4 the green LED will illuminate with a solid light. The blue LED will illuminate with a solid light when the locking signal is activated. -
After installation, check the locking function.
Caution! After installation, check the locking function and that the surfaces of the magnet and the anchor plate are parallel, i.e. that full contact is obtained when the door is closed. If the anchor plate tilts, the holding force of the lock can be significantly reduced or eliminated.
Maintenance
- Warning! The safety functions and the mechanics shall be tested regularly. Check correct operation of all circuits and the locking function at least once a year.
- Warning! A defective unit shall be replaced with a new unit. Never bypass the safety circuit.
- Warning! In case of breakdown or damage to the product, contact nearest ABB Electrification Sweden service office or reseller. Do not try to repair the product yourself.
- Warning! ABB will not accept responsibility for failure of the switch functions if the installation and maintenance requirements shown in this document are not implemented.
- Caution! The electromagnet shall be regularly cleaned to maintain its full holding force. Dirt or dust on the anchor plate or Magne can cause low or no holding force.
