11.1 Safety sensors DA001 and DA002
On the opening side
On the closing side
The loop must have a 1K resistor in parallel across the terminals 1 and 4. This must
be fi tted in safety sensor, in order that the door operator monitors the condition of
the cable between the sensor and the operator. This cable is vulnerable due to the
door’s movement, and in the event of an open circuit it will prevent a potentially
unsafe door opening.
When sensor detects an obstacle, the operator stops the door.
When sensor detects an obstacle, the operator opens the door for duration of the
hold open time.
