They can be field modified to operate in one direction only (Clockwise CW; Counter clockwise Figure 15. Retaining screw location CCW) by following these steps: 1. Carefully remove the complete head assembly. 2. Turn the head assembly upside down as shown in Figure 14. 3. Pull the plunger mechanism out and rotate it through 90° increments until the alignment tab points to the desired func- tion (CW, CCW, or CW and CCW). 4. Push plunger mechanism in. 5.

Wiring Diagram 2 Plug-in EN50041 body style The switch enclosure portion of this two-piece body style plugs into a pre-wired terminal block mounted in the application. Replacement is accomplished by unplugging the old switch enclosure and plugging-in a new switch enclosure (basics are permanently staked in the switch enclosure). LED WIRING The GLF, GLG, and GLH versions of GLS (EN 50041) come In Figure 17, Wiring Diagram 2, the basic switch contact is complete with LED indicators. These indicators can be wired in a closed.

Wiring Diagram 4 In Figure 16, Wiring Diagram 1, the basic switch contact is open. The current for the LED can flow through the LED (via the load) and the LED illuminates. In Figure 19, Wiring Diagram 4, when the load is energized the LED will illuminate. The above examples suggest options with these versions of GLS. The LED pilot lights should be treated as ’’for indication only’’ devices. Note: While every effort is made to ensure that the above guidelines are accurate, no responsibility can be accepted for failure to apply good engineering practice to machinery design and use of Honeywell products. Never apply any of the procedures outlined above on live circuits. Ensure that testing of changes is carried out with no risk of injury during tests. These guidelines are produced to help our customers make the right choices in applying our Limit Switches to general applications.
