Task
The relay module's relay contacts can be used to report the following door states to the
higher-level control device:
Table 4- 4 Door states SIDOOR AT40 RELAY / ATD400V
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 incremental sensor
ceases to output pulses, i.e. the door is stationary or the DCPS signal is active. Pin 3 only remains connected
to pin 1 until the "Open door" 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 reverse 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.
If the door blocks at a move command "CLOSE DOOR with nudge", relay X12 remains inactive by default.
Relay X12 can be activated if obstructed during nudging by using the Service menu "General setup > Special
parameters > BLK at nudge Rev.Relay".
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.
Risk of injury
The door control system is not a safety mechanism. Therefore the relay contacts must not
be used for the elevator safety circuit.
Connection
Risk of injury from dangerous electrical voltages
When the enclosure cover of the control device is open, only a safety extra-low voltage of
less than 42 V may be present. The protective cover provided must be used when a higher
voltage (max. 230 V AC) is connected to the relay module. Please follow the procedures
described below for connecting a relay module.
