Low Or No Holding Force; Testing Safety Function; Replacing Eva Unit - ABB Magne 3 Product Manual

9.3

Low or no holding force

•
Check that there is no dirt or dust on the anchor plate or Magne.
•
Check that the position of the anchor plate with Magne is calibrated and that anchor
plate is flat, parallel and aligned to Magne when closed.
•
Check that Magne is installed close to the door handle.

Testing safety function

This section only applies to Magne 4.
Same tests shall be performed when using an external interlocking safety device together
with Magne 3.
Check the safety functions by following these steps:
1. Interrupt the safety circuit before this unit when Eva is within sensing distance to Adam
(door closed). The LED shall flash green and red and the safety control module go into
safe state. See more information in chapter "Led indications".
2. When door closed, reset both the safety circuit before this unit and the safety control
module. The LED shall illuminate solid green.
3. Move Eva away from Adam. The LED shall change from green to red and the safety control
module should go to safe state (safety circuit broken, door open).
4. Move Eva back close to Adam and reset both the safety circuit and the safety control
module. The LED shall illuminate solid green (safety circuit closed, door closed).
9.5

Replacing Eva unit

When replacing an Eva unit (with unique code or with general code), to an Eva with unique
code, the old code in the integrated Adam sensor first must be erased. Follow the
instructions below for Magne 4 with Adam DYN or Adam OSSD.
To replace an Eva with general code to another Eva with general code, the instructions below
are not necessary.
Erase code in Magne 4 DYN
1. Move the old Eva out of sensing distance from Adam.
2. Disconnect the power supply from Magne (0 V should always be connected).
3. Connect +24 VDC to DYNLINK signal in.
4. Connect the power supply to Magne (marked +24 VDC).
5. Disconnect the power supply from DYNlink signal in after 5 seconds and within 10
seconds. The Adam unit in Magne is now reset and the LED on Magne should flash
red.
6. Disconnect the power supply from Magne (marked +24 VDC).
7. Remove the old Eva.
8. Install the new Eva and move it within sensing distance to Adam.
