Typical Installations
Switch Mounted Parallel to
Hinge Axis
The Z position can be carefully selected to offset the anticipated door sag or
door drop. Simultaneously, be sure that the alignment is such that it is not
possible to lift the door up and off the locking bolt. Also make sure that there is
no possibility that the actuator would collide with the switch when the guard
door is being closed. It is essential to check the alignment periodically
throughout the use of the guard locking switch.
The X and Y positions can
be adjusted using the slotted
holes of the mounting
bracket and appropriate
selection of the three pairs of
actuator bracket holes, once
the bracket is centered.
The tolerance to
misalignment is
±2.5 mm (0.10 in.).
The Z (height) position is
adjusted by sliding the
actuator bracket up/down
on the profile. If the setting
gap is centered between the
minimum of 0 mm and the
maximum of 5 mm
(0.20in.), a tolerance to
misalignment of ±2.5 mm
(0.10 in.) is achieved.
