To test the setting height of the internal VES pre-limit switch, place the VES gauge or a similar implement (height: 50 mm, e.g.
wooden slat, pipe or similar) on the ground under the door, in the middle of the clearance of the door opening. If the door hits the
50 mm high VES gauge or another implement, it must stop immediately and then move away from the simulated obstacle (open).
If that is not the case, check the connection and the adjustment of the safety edge again, and reprogram the door limit positions.
To check the functional switch-off of the safety edge by the internal pre-limit switch (VES),
always observe the EN 12453 standard: Safety in use of power operated doors – test
methods.
Safety input SE1, SE2, emergency stop
Caution
It is imperative that the EN 12453 standard be observed: Safety in use of power operated
doors – test methods. The closing force must be reduced to less than 150 N after no more
than 750 ms, and less than 25 N after a total time of 5 seconds.
To find out the position of the connecting terminals, please see the chapter "Position of
the terminals and components and complete connecting diagram": P.991: 0 or 1 Mechan-
ical limit switching or Position of the terminals and components and complete connecting
diagram: P991: 2 Absolute value encoder.
Safety devices can be connected. Light barriers and pull-in safety devices are connected to the function inputs FE. Any existing
jumpers must be removed.
The control unit provides the following inputs, which are self-monitoring:
•
2x Emergency stop
•
2x Safety input
The following systems can be directly connected to a safety input:
•
Electric safety edge (EL) with 1.2 kΩ or 8.2 kΩ terminating resistor.
•
Pressure-wave safety edge (DW) with 1.2 kΩ or 8.2 kΩ terminating resistor.
•
Optoelectronic safety edge: OSE signal output
•
PNP output, NPN output
•
Wicket door switch in series with slack rope switch with terminating resistance 5.1 kΩ
EMERGENCY STOP
Safety devices can be connected to the terminals NA1 (e.g. thermoswitch) and NA2 (e.g. EMERGENCY STOP push-button). Activ-
ation causes the door to be stopped. For the duration of activation, all further door movement is prevented. The safety devices,
e.g. a pull-in safety device, must be intrinsically safe and switches must be forcibly actuated. Otherwise, they must be connected
to a function input and tested.
Electric safety edge
The required sensor is integrated in the control unit (self-monitoring sensor as per EN 12453). Check the terminating resistance of
factory-installed electrical safety edges.
Pressure-wave safety edge (DW)
If a pressure-wave safety edge (DW) is used, SE1 or SE2 must be parameterised as the DW edge, as the DW edge must be tested
in the CLOSE limit position. The DW edge must trigger underneath the pre-limit switch (VES). The pressure-wave safety edge
needs a terminating resistor.
Optoelectronic safety edge: OSE signal output
The optoelectronic safety edge OSE is connected directly without a terminating resistor. A second OSE signal can be evaluated at
FE1.
PNP output, NPN output
Safety devices, e.g. leading light barrier, can be evaluated. These devices must be tested to achieve category 2 according to EN
13849-1. To do so, use a relay switching output for external testing. Testing is carried out before the movement.
