DCOPS (door closed/opened position sensor)

Function description
"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.
In the case of an active DCOPS signal in initial mode, the control unit switches directly to normal
mode with corresponding drive order "Open" or "Close" and detected blocking (end stop). 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. Control unit is in the initial mode. No fault present. The system is in any position along the
travel path.
3. A door command "Open" or "Close" is applied.
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.
Connection and parameter assignment
The DCOPS signal can be connected to SIDOOR ATD4xxW control units via "Input 1" of the
terminal X6. See also section Digital input signals (Page 132).
The connected signal must be activated via the SIDOOR service menu (Main menu > General
setup > Special parameters > Input 1).
Note
The ESPE, pressure sensitive edge, light barrier and DCOPS functions cannot be implemented at
the same time.
