APPLICATION INFORMATION

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 dia-

grams 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.

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.

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).

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.

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.

Basic Switches

3. Retighten the Allen screw.

Non-plug-in

4. Check to see if the free position is satisfactory for the

application.

Basic switches can be removed and replaced by following this

procedure:

5. Repeat the adjustment procedure if necessary.

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.

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

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).

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:

8. Test the switch in its application.

Figure 15. Retaining screw location

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. Reassemble the head assembly and re-test the switch in its

application.

Basic Switches

Figure 17. 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

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.

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.

2 LED

The following wiring diagrams show possible conﬁgurations

that can be used for the LEDs. Combinations of these arrange-

ments can be used where the dual LED versions of GLS are

employed.

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 16. Wiring Diagram 1

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.
