Task
The relay module's relay contacts can be used to report the following door states to the
higher-level controller:
Table 4- 4
Door states SIDOOR ATD400T
Relay
Function
contact
X11
The function of the relay can be set via the "X11 mode" parameter:
MAIN MENU > Service > Special > X11 mode
IR sensor
No function, the relay is permanently deenergized. Pin 2 is connected to Pin 3.
Button illumination (button)
The relay switches on in the following cases:
•
The controller detects the "Locked" position ("Door locked" input active). The door is locked.
•
The controller is in wait mode after a detected obstruction.
•
An error was detected at the door.
In this case, Pin 1 is connected to Pin 3.
If the "Locked" command is reset, the relay is deenergized again with a time delay of 3 s. In this case, Pin 2 is
connected to Pin 3.
During the learn run, the relay is continuously switched on and off at a cycle of about 500 ms.
If there is an open request from the door button, the relay is switched on and off for about 500 ms.
X12
Error output
The relay switches on when the controller is in an error-free state. See also section Status display (Page 98)
•
No error: Pin 1 is connected to Pin 3.
Error: Pin 2 is connected to Pin 3.
•
If there is no voltage to the controller, this is detected as an error.
The function of the relay can be enabled via the "Time delay motion" parameter:
X13
MAIN MENU > General setup > Time parameters >Time delay motion
0 ms = Disabled
External lock
An external lock (door lock) can be locked or unlocked with the X13 relay. For this purpose, the relay X13 is
enabled first on opening/closing. A door motion is only initiated after the "Time delay motion" has elapsed.
When the door reaches the "Open" or "Closed" position, the relay X13 is disabled.
The relay X13 must be enabled using the "Time delay motion" parameter. The "Time delay motion" parameter
can be set in the range from 0 to 5000 ms at increments of 100 ms. A value of 0 means that the relay X13 is
disabled.
Risk of injury
The door controller is not a safety mechanism. The relay contacts must therefore not be
used for the safety circuit of the vehicle.
