Detecting motion

During business hours, the motion detector B1 initiates the

opening of the door when somebody wants to enter the

shop. Motion detector B2 initiates the opening of the door

when somebody wants to leave the shop.
After closing time, the motion detector B2 continues to be

used to open the door for 1 hour to allow the customers to

leave the shop.

Actuating the motor for opening

Output Q1 is set and opens the door when:
• The control switch at I5 is actuated (the door is

permanently open), or

• The motion detectors indicate that somebody is

approaching the door, and

• The door has not yet fully opened (limit switch at I4).

Actuating the motor for closing

Output Q2 is set to close the door when:
• The control switch at I6 is actuated (the door is

permanently closed) or

• The motion detectors indicate that there is nobody near

the door, and

• The door has not yet fully closed (limit switch at I3).

Buzzer

Connect the buzzer to output Q3. The buzzer gives a brief

warning (in this case 1 second) when the door is closing.
