Task
The relay module's relay contacts can be used to report the following door states to the
higher-level controller:

Relay Function
contact
X11 The door has reached the "CLOSED" position
The relay switches on when the controller has detected the CLOSED position and the pulse generator ceases
to output pulses, i.e. the door is stationary. Pin 3 only remains connected to Pin 1 until the "DOOR OPEN"
command is issued. The relay then drops out again immediately, and Pin 3 is once again connected to Pin 2.
X12 Door reverses because of an obstruction, interruption of the light barrier or an opening command.
The relay switches on when the door reverses because of an obstruction, interruption of the light barrier or an
opening command. Pin 1 is then connected to Pin 3 until the OPEN position is reached.
X13 The door has reached the "OPEN" position.
The relay switches on when the distance of the door from the OPEN position falls below 2 cm. Pin 1 and Pin 3
are then connected. The relay drops out immediately as soon as the distance exceeds 2 cm again, and Pin 3
is once again connected to Pin 2.

Function
The system's internal door state "closed" is signaled via this relay (relay contact is closed).
This state is not only position-dependent. Note the following conditions:
The "closed" state can only be achieved with a drive order
•
The "closed" state cannot be achieved by external pushing
•
The "closed" state can be terminated by means of a drive order or external pushing
•
The relay is additionally influenced by the sensor configuration (parameter p4600). See also
Section Sensors and external sensor interface module (ATD4xxW) (Page 159).
Sensor function test inactive
•
The control signals that the current drive order's direction is reversed.
Example: automatic reversing due to an obstruction, provided that the applicable revers-
ing response is parameterized.
The relay is active as long as the current drive order is inversed.
Sensor function test active
•
The "TestOUT" sensor function test signal is output.
The system's internal door state "open" is signaled via this relay (relay contact is closed).
This state essentially depends on the current door position.
The "open" state can be achieved both by means of a drive order and also by external
•
pushing.
The state can be terminated by means of a drive order or external pushing
•
There is a fault in the system if both relays are simultaneously active (relay contacts closed).
