The EN 50041 body style allows infinite adjustment and reclamp. See the following diagrams for details of the mechanism in each case. Figure 14. Actuation Adjustment Figure 12. Standard EN 50041 Body Style There are two lever mounting options: 1. By fully seating the lever in one of the four 90° detent posi- tions on the shaft hub which provides positive lever retention. 2. By mounting the lever on the serrated portion of the shaft (which enables the lever to be mounted in any position). To change the rotary lever's free position: 1. Use a 3 mm hex Allen wrench to loosen the Allen screw, as shown in Figure 13, below. 2. Back off the lever 2 mm and move it to the desired free position. 3. Retighten the Allen screw. 4. Check to see if the free position is satisfactory for the application. 5. Repeat the adjustment procedure if necessary. A teller tab located at the bottom of the lever (see diagram below) helps prevent lever slippage. It enables the installer to detect the correct tightening torque. When this tab cannot be moved, the Allen screw has been tightened properly. Figure 13. Allen Screw and Teller Tab Location EN 50041 Side Rotary Actuator Direction Adjustment As furnished, GLS rotary switches will operate when the lever is rotated from either the left or right. They can be field modified to operate in one direction only (Clockwise CW; Counter clockwise 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 function (CW, CCW, or CW and CCW). 4. Push plunger mechanism in. 5. Reassemble the head assembly and re-test the switch in its application. REPLACEMENT INSTRUCTIONS All levers for side rotary assemblies are available as replacment parts. All basics, except the plug-in, can be replaced. All EN 50041 heads can be replaced. The replacement procedures for these components are straightforward in nature. Side Rotary Levers Remove the lever from the product being replaced. On EN 50041 product this is achieved by loosening the Allen screw holding the lever on the shaft. Replace the lever and tighten the Allen screw or combination screw. Re-test the switch in its application. Heads All EN 50041 style switch heads can be removed and replaced. 1. Remove the head by unscrewing the four retaining screws on the head assembly. 2. Ensure replacement part is identical to one being removed. 3. Re-test the assembly and ensure correct operation. Basic Switches Non-plug-in Basic switches can be removed and replaced by following this procedure: 1. Remove the cover from the body. 2. Before disconnecting the switch wiring, carefully note the wir- ing arrangement for your application, particularly the safety ground connection. 3. Remove the basic switch retaining screw. 4. Remove the basic switch and install the replacement basic switch. 5. Use the retaining screw to install the new basic switch ensure that it is correctly seated in the switch body. 6. Wire the switch terminals as before. 7. Before replacing the cover ensure that the basic switch wires are not twisted or otherwise lifted from the basic switch (to prevent them from becoming trapped when the cover is replaced). 8. Test the switch in its application. Figure 15. Retaining screw location MICRO SWITCH GLA Series Limit Switch Datasheet | sps.honeywell.com/ast | 20 MICRO SWITCH GLOBAL LIMIT SWITCHES, GLA SERIES Basic Switches 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). Figure 17. Wiring Diagram 2 LED WIRING The GLF, GLG, and GLH versions of GLS (EN 50041) come complete with LED indicators. These indicators can be wired in a variety of ways. Operation can indicate switch free or switch operated depending on the wiring arrangement employed. The table below indicates the body styles and indicators offered. Table 12. LED Series Body Function Specification GLF GLG 1 LED 1 LED plugin 12 Æ 250 Vac and dc less than 1.5 mA draw 12 Æ 250 Vac and dc less than 1.5 mA draw GLH 2 LED 18 Æ 30 Vdc 7 mA typ. current draw In Figure 17, Wiring Diagram 2, the basic switch contact is closed. The current for the LED cannot flow through the LED and the LED will not illuminate. Figure 18. Wiring Diagram 3 The following wiring diagrams show possible configurations that can be used for the LEDs. Combinations of these arrangements can be used where the dual LED versions of GLS are employed. Figure 16. Wiring Diagram 1 In Figure 18, Wiring Diagram 3, regardless of the position of the basic switch, the current for the LED can flow through the LED and the LED will illuminate indicating power available. Figure 19. 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.
