X2: Safety edge system
The door control automatically detects three different safety edge systems. If no safety edge
system is detected fault “F2.0” is displayed.
Important!
•
Safety Edge Systems must comply with BS EN 12978!
1K2 resistor evaluation
This safety device is intended for a pneumatic switch with NC contact in series with a resistor
of 1K2, +/-5 %, 0.25 W. If activated, pressure is generated in the rubber profile which
activates the pneumatic switch.
The safety edge system must be tested at the end of every door close cycle. The test is
initiated when the door reaches the “safety edge pre-limit” position. The safety edge switch
must be activated against the floor within 2 seconds of operating the pre-limit switch. If the
pneumatic switch is not activated, the test has failed and fault "F2.8" is displayed.
If there is a short-circuit in the safety edge system, fault "F2.7" is displayed.
Upon activation or permanent disconnection, fault "F2.6" is displayed.
In all cases, closing of the door is only possible in the "hold-to-run" door operating mode.
8K2 resistor evaluation
This safety device is intended for an electrical safety edge system with end of line resistor of
8k2, +/- 5 % and 0.25 W.
If activated, there is a short-circuit and fault "F2.4" is displayed.
If there is an open circuit, cable broken/disconnected, fault “F2.5” is displayed.
