Head and Lever Positions
The operating head can be positioned and locked in any of four 90° positions and a lever can lock in any position through 360° around the shaft of
the Limit Switch. Furthermore, the lever can be reversed and attached to the shaft (refer to the figures below on the right hand side). Therefore the
roller is compatible with a wide movement range of a dog. A Fork Lever Lock can be used with maintained models (D4A-0005N) only.
Remove the head from the Switch by
loosening the screws (the screws can be
loosened but not removed from the
head).
Four, M4 x 12
There are four kinds of fork lever locks. The position of each
roller is different. It is possible to use D4A-E00 through
D4A-E30 levers instead, if they are reversed before attaching.
They can be used with D4A-@@05N models only.
By loosening the Allen-head bolt on an adjustable roller lever
or rod lever, the length of the lever can be adjusted.
Lighting Mode Selection of Indicators
The lighting mode of the operation indicator can be changed easily between two modes: lighting when the Switch is operating and lighting when
the Switch is not operating.
