Assembling the limit switch magnets

The front and rear limit switch magnets must always be
assembled on the right side of the sensor head.
If the emergency stopping distance exceeds the length of
a limit switch magnet, several magnets may be lined up.
The limit switch sensor becomes active once it moves into
the magnetic area of the limit switch magnet.
