DCOPS (door closed/opened position sensor)

Description of function
"DCOPS" stands for door closed/opened position sensor. A door closed/opened position
sensor can consist of two end position sensors (closed/open).
The DCOPS enables the door to travel immediately after the line voltage is switched on
without an initialization run in normal operation.
When the DCOPS signal is active in initial mode, the controller switches directly to normal
mode with a corresponding "Open" or "Close" drive order when an obstruction (end stop) is
detected. To prevent the erroneous detection of a blocking obstruction as an end stop, the
DCOPS signal must not be activated until 1 to 2 cm before the respective end stop.
Example sequence when using DCOPS
1. Power ON
2. Controller is in the initial mode. No fault present. The system is in any position along the
travel path.
3. An "Open" or "Close" door command is present.
4. The system opens or closes.
5. The DCOPS signal is activated as from 2 cm before the respective end stop.
6. The system reaches the end stop and detects it as an "obstruction".
7. The system switches to the normal mode and assumes the applicable "open" or "closed"
status.
