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

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 (Page 166).
• 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 reversing
response is parameterized.
The relay is active as long as the current drive order is reversed.
• 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).
