2.6 FUNCTIONALITY OF THE PETWALK PET DOOR
Unlike conventional manual cat flaps, which your pets have to open with their head, petWALK uses a completely
different construction principle. A highly thermally insulated door leaf is moved by a powerful motor. When
closed, the door leaf is pressed firmly against a circular (O-Ring) seal and locked mechanically. This provides a
completely airtight lock and a high degree of anti-burglary security.
The petWALK pet door is controlled fully electronically. When the pet approaches, your petWALK pet door
recognises it with the help of the theremin and motion sensors and thus opens the door leaf. If the RFID access
control is activated, the door operates as follows: The theremin and the motion sensors recognise movement
and activate the RFID antenna. This emits a magnetic field and activates the RFID collar tag of your pet. The
chip sends a signal and the petWALK pet door opens - given that this particular chip has been programmed to
the petWALK pet door prior. You can find more detailed information regarding RFID in chapter 6 „RFID acceess
control“.
2.7 THE PETWALK SAFETY CONCEPT
There are several independent security mechanisms built into the petWALK pet door. The door fulfils all safety
requirements. Despite the highest requirements and best technical development, there is no 100% perfect
product and a certain amount of risk resides. This is why your pet should leave the opening and closing area
immediately.
2.7.1 MOTION MONITORING
The petWALK pet door recognises animals with the help of two highly sensitive motion sensors (one on the
outside and one on the inside) and closes once no movement has been detected within a defined period of time.
If the animal lingers in the doorway without moving, the door leaf might begin to close as the sensors cannot
detect any more movement. This is the same effect that you get in elevators or automatic doors in department
stores if you stand still in the doorway or quickly step into the doorway whilst it is closing. Should this happen,
it is not a problem as another safety measure kicks in - motor current monitoring.
2.7.2 ELECTRONIG ANTI-JAMMING PROTECTION (MOTOR CURRENT MONITORING)
If the door leaf encounters a slight resistance when closing or opening, it will immediately come to a halt before
opening up a little again. After a while, the petWALK pet door will produce a warning tone before trying to close
the door leaf carefully once again - however, this time with a little more pressure. After multiple failed attempts,
the petWALK pet door goes in to alarm status to indicate a problem - for example, an object could have fallen
over and therefore be blocking the petWALK pet door.
You can check this functionality easily yourself by placing your hand into the doorway and remaining still, so
that the door leaf starts to close. Should there be an electronic malfunction, there is no need for you to worry
as there is a further mechanical safety measure (presented below). After four failed attempts, the petWALK pet
door displays the error code “E02” on the display.
Should the door leaf fail to stop immediately and move in the opposite direction, but instead exert very light,
continuous pressure and after a few seconds display the error code “E03”, the mechanical anti-jamming
protection is set too lightly. You can adjust this yourself as described in chapter „10.5 ADJUSTING THE SLIP
CLUTCH“.
