FEATURES
DESCRIPTION
Honeywell’s MICRO SWITCH™ GLA Limit Switch Series is
designed to global EN50041 standards and well suited for
worldwide applications. The modular design (heads/actuators,
bodies, and contact blocks) of the limit switch allows for rapid
response to meet customer applications. The rugged die-cast
metal housing of the switch is ideal for indoor and outdoor
applications where a degree of IP or NEMA enclosure sealing
is required. Normally closed snap-action contacts and normally
closed slow-action contacts are positive opening
.

APPLICATION INFORMATION
Figure 14. Actuation Adjustment
Side Rotary Assemblies
The side rotary assemblies incorporate a feature for adjusting the
free position of the side rotary lever. The EN 50041 body style
allows infinite adjustment and reclamp. See the following diagrams for details of the mechanism in each case.
Figure 12. Standard EN 50041 Body Style
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.
There are two lever mounting options:
1. By fully seating the lever in one of the four 90° detent positions 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.
20
sensing.honeywell.com
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
wiring 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™ 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

12 Æ 250 Vac and dc less than 1.5 mA draw
GLG
1 LED plug-in 12 Æ 250 Vac and dc less than 1.5 mA draw
GLH
2 LED
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
18 Æ 30 Vdc 7 mA typ. current draw
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. Contact your local Honeywell representative if you have any difficulties.
