3.3 Connecting the safety contact strip (Safety 1)
Safety contact strips are available in two models:
• Optical safety contact strip from FRABA (1) or
• Electrical 8 kOhm safety contact strip (2)
The safety contact strip is attached to the closing edge of the door. It
protects persons against the risk of entrapment from the closing
edges and prevents damage to objects. As soon as it is activated
when the door is closing (by an obstacle or person), the control unit
stops the operator and changes the direction of travel. The setting of
DIP switches 3 and 4 determines how the control unit responds or
how far the door travels in the opposite direction when an obstacle is
encountered; see Chapter 6.15 “Operator response to detected
obstacle”.
If the safety contact strip is activated, faulty or not connect ed, dead
man operation is automatically activated; see Chapter 4.1 “Activating
dead man operation”.
