2.7.3 MECHANICAL ANTI-JAMMING PROTECTION (SLIP CLUTCH)
The drive motor is connected to the door leaf via a mechanical clutch, that automatically interrupts the power
transmission at a certain resistance level. This resistance level has been set in order to ensure that the petWALK
pet door cannot under any circumstances cause a serious injury should any of the electronic safety features fail.
the level of force can reduce over time as a result of wear and tear of the clutch discs. In the worst case, the
electronic anti-jamming protection might not work as the slip clutch will stop the door at a lower resistance
level. Should this be the case, you can reset the slip clutch - see capter „10.5 ADJUSTING THE SLIP CLUTCH“.
You can test this mechanism easily yourself by manually pressing the door leaf open and closed whilst it is
open. This should be possible without exerting too much pressure. The force you require is the maximum force
that can theoretically be exerted on an objected jammed in the doorway.
2.7.4 CONSTRUCTIONAL ANTI-JAMMING PROTECTION
petWALK pet doors uses two independent motors in order to be able to move the door leaf as softly as possible,
yet lock it tightly.
The door motor only uses the amount of electricity it requires for any given movement. The locking motor is only
activated once an electrical contact is closed and if the size of the gap on the side facing away from the axel is
less than 8 mm / 0.3 in. A small wedge on the top of the door leaf and a bolt on the locking mechanism are used
to ensure this. The bolt on the door leaf can only be shut tightly once the size of the gap on the side facing away
from the axel is in the safe range. Otherwise, the bolt stops the door leaf from closing.
HINT!
Despite all of the safety devices mentioned above, please make sure that your
pet or its tail doesn‘t linger in the petWALK pet door.
“Soft” obstacles such as
a cat‘s tail may not be optimally recognised by the safety devices and could thus,
lead to a risk of crushing. petWALK
does not give any guarantee or accept any
liability
regarding this risk.
