2 Electrical connection
All electric signals are transferred trough the male 15-pin D-sub-miniature connector on top of the motor
lock.
Note: You will need a mating connector (female 15-pin D-sub-miniature connector) and the appropriate
cable to connect the lock to your higher-level control unit. None of the two elements are included in the
package. We recommend using a shielded D-sub cable.
2.1 Pin wiring
Bridge pins Motor+ and Motor- in order to distribute the load generated by the motor and to be carried by
the connectors among three plugs each (pins 6, 12, 14 and pins 11, 13, 15).
Note: The sensor functions inside the motor lock are provided by light
barriers.
2.2 Motor actuation
The polarity defines the direction in which the motor turns:
Forward (open)
+24 V on pins 6, 12, 14 / 0 V on pins 11, 13, 15
Backward (close):
0 V on pins 6, 12, 14 / + 24 V on pins 11, 13, 15
Short-circuit the connectors after stop!
Turn off the motor voltage at the target position (sensor x). Ensure that the motor connectors
short-circuit immediately afterwards. This means immediately stops the drive and prevents the
motor from moving across the sensor.
Never go across the motor end positions!
The motor must turn off at one of the end positions. Otherwise (if the lock goes across the end
positions), you run a risk of mechanical damage because the motor lock has no mechanical limit
stops.
