Pawl reset Procedures
NOTE: The latch will prevent the pawl from back rolling if the door bounces when engaging, as shown in Fig. 7-B.
To disengage the Pawl, the operation will need two (2) persons, one to unlock the latch and another to press “OPEN” button on the control panel to disengage
the Pawl.
- To unlock the Latch, press the bottom of the Latch with the forenger, and the elbow of the Latch is resting on the stopper pin as shown. Finger must NOT
touch the pawl or enter the stator ring, as shown in Fig. 7-C.
- Hold still while the second person presses the “OPEN” button to open the door.
- When opening the door to disengage the Pawl, continue pressing the bottom of Latch to ensure the Latch is out of the way of the catch.
- Release nger only after the Pawl is completely out of the notch of the Stator.
If the Catch gets locked by the Latch when disengaging the Pawl, press “CLOSE” button to unlock latch, and then press “STOP” immediately.
Repeat the steps described above until the Pawl is disengaged, as shown in Fig. 7-D.
