Minimum Safety Distance; Installation Instructions - ABB Magne 3 Product Manual

Minimum safety distance

When using interlocking guards without guard locking to safeguard a hazard zone, the
minimum allowed safety distance between the guarded opening and the hazardous machine
must be calculated.
In order to ensure that the hazardous machine motion will be stopped before it can be
reached, the minimum safety distance is calculated according to EN ISO 13855: 2010
("Positioning of safeguards with respect to the approach speeds of parts of the human
body").
The minimum safety distance is calculated according to the formula:
S = (K x T) + C
Where:
S = minimum safety distance (mm)
K = approach speed of a human body (1600 mm/s)
T = the total time from opening of the guard until the hazardous machine movement has
stopped, including control system reaction times and other delays (seconds)
C = a safety distance (mm) taken from Table 4 or Table 5 of EN ISO 13857:2008; if it is
possible to push fingers or a hand through the opening towards the hazard before a stop
signal is generated.
Note! In some cases, T might be reduced by the opening time of the guard until the
opening size permits access of the relevant parts of the body. Refer to EN ISO
13855:2010 for further details and EN ISO 13857:2008 for specified values.

Installation instructions

1. 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 (see chapter 'Mounting
kits').
2. Calibrate the position of the anchor plate with Magne according to chapter 'Anchor plate
installation'.
3. Make sure Eva is correctly positioned and oriented in relation to the integrated Adam
sensor in Magne 4 (see chapter 'Positioning and orientation of Eva with Magne 4').
4. Connect the pin out according to chapter 'Connections'.
5. Connect the M12 connector to Magne.
Note! Make sure no power supply is connected when cable is fitted to the Magne
M12 pin out.
6. Close the door to put Eva within sensing distance of Adam.
7. 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.
8. After installation, check the locking function.
