1.5 Recycling and disposalMost limit switch parts can be recycled if sorted accord-ing to material. See the list below for materials. In addi-tion, separate recycling and disposal instructions areavailable from us. A limit switch can also be returned tous for recycling and disposal against a fee.

1.6 Safety precautions

2 MOUNTING AND INITIAL SET-UP2.0.1 Mounting to ISO-NAMUR style

actuatorsAttach spacer or bracket to actuator with fasteners pro-vided and tighten securely. Attach function module tospacer or bracket and tighten securely.Place the Drive Block into the slot of the actuator shaft.Next, place the Inner Drum over the Drive Block, ensur-ing the Drive Block goes into the mating recess of theInner Drum. Now slide both Trigger Adjustment Ringsover the Inner Drum. Finally, insert the Drum Fastner(provided with the mounting kit) through the entireVisual Indicator/Trigger Assembly and tighten only acouple of turns into the actuator shaft as to allow theTrigger Adjustment Rings to rotate freely to perform thesensor settings. Ensure the assembly is centered.

2.0.2 Sensor settingsStart with the actuator in the closed position. Ensure theDrum Fastener is loose enough to allow the Trigger

Adjustment Rings to rotate. Lift and rotate the lower ringuntil the stainless steel trigger is in front of the lowerbulls-eye on the Function Module (lower trigger acti-vates the Red LED). Rotate the actuator to the openposition. Lift and rotate the upper ring until the stainlesssteel trigger is in front of the upper bulls-eye on theFunction Module (upper trigger activates Green LED) .Securely tighten the Drum Fastener. To adjust simplyloosen screw and adjust triggers and indicator to suityour application. LEDs will energize and de-energizewhen powered, indicating sensor status.

2.0.3 Indicator CoverInstall the Visual Indicator Cover. The Cover AlignmentRibs on the Visual Indicator Cover are tapered and can-not be inserted vertically into the mating grooves on theFunction Module. Place the Visual Indicator Cover overand as close to the Visual Indicator/Trigger Assembly aspossible. When the bottom of the Visual Indicator Coveris flush with the base of the Function Module, slide theVisual Indicator horizontally until the Cover AlignmentRibs fit completely into the mating grooves on the Func-tion Module. Tighten the Visual Indicator Cover securelyto the actuator with fastners provided in the mountingkit.

2.0.4 WiringEN series:Raise the hinged Function Module cover by looseningthe two cover screws. Attach control and solenoid wiresas indicated on wiring diagrams located in Section 4.Close cover and securely tighten cover screws. Note: Ensure adequate drainage of wiring conduit toprevent water contamination inside enclosureEG series:Control and solenoid wires are connected to the EclipseFunction Module via M12 micro-connectors as per infor-mation located in Sections 4.8 thru 4.15.

CAUTION:Do not exceed the permitted values!Exceeding the permitted values marked on the limitswitch may cause damage to the switch and to equip-ment attached to the switch and could lead to uncon-trolled pressure release in the worst case. Damage tothe equipment and personal injury may result.

CAUTION:To prevent ignition of hazardous atmospheres,replace cover before energizing the electrical circuits.Keep cover tightly closed when in operation.

INSTALLATION NOTES Intrinsically Safe Installations: (Ex ia IIC T5):EN44___ Entity Parameters: Ui = 22 Vdc; Ii = 120 mA ; Ci = 98 nF; Li = 1.56 mH; Pi = 2.0 W

1. The Entity Concept allows interconnection of intrinsically safe apparatus with associated apparatus when the following is true:Ui >Uo; Ii > Io; Pi > Po; Co > Ci + Ccable, Lo > Li + Lcable.

2. For Installations in Europe, control room equipment connected to intrinsically safe associated apparatus shall not use or generate more than the marked Um of the associated apparatus.

3. Installation in Europe shall be in accordance with latest editions of the wiring practices for the country of origin.4. For Installations in Europe, the Associated Apparatus must be ATEX approved. Associated apparatus manufacturer's

installation drawing must be followed when installing this equipment.5. To maintain intrinsic safety, wiring associated with each sensor must be run in separate cables or separate shields connected

to intrinsically safe (associated apparatus) ground. Each sensor shall be wired as separate intrinsically safe circuits.6. Conduit Grounding - Upon installation verify electrical continuity between conduit and ground terminal.7. Resistance between Intrinsic Safe Ground and earth ground must be less than 1.0 ohm.8. Parts of the enclosure are non-conducting and may generate an ignition-capable level of electrostatic charge under certain

extreme conditions. The user should ensure that the equipment is not installed in location where it may be subjected toexternal conditions (such as high-pressure steam) which might cause a build-up of electrostatic charge on non-conductingsurfaces. Additionally, cleaning of the equipment should only be done with a damp cloth.

9. Substitution of components may impair hazardous location safety.10. No revision to drawing without prior FM Approval.

1. Uo < Ui (Vmax); Io < Ii (Imax); Ca > Ci + Ccable, La > Li + Lcable.2. Control equipment connected to barrier must not use or generate more than 250 Vrms or Vdc.3. Installation should be in accordance with ANSI/ISA RPA12.6.01 "Installation of Intrinsically Safe Systems for Hazardous

(Classified) Locations" and the National Electrical Code (ANSI/NFPA 70) or in accordance with the Canadian Electric Code.4. Associated apparatus manufacturer's installation drawing must be followed when installing this equipment.5. To maintain intrinsic safety, wiring associated with each sensor or solenoid coil wiring must be run in separate cables or

separate shields connected to intrinsically safe (associated apparatus) ground. Each Sensor and Solenoid coil shall be wiredas separate intrinsically safe circuits.

6. Shield Grounding - Upon installation verify electrical continuity between shield and ground terminal.7. Resistance between Intrinsic Safe Ground and earth ground must be less than one ohm.8. Parts of the enclosure are non-conducting and may generate an ignition-capable level of electrostatic charge under certain

extreme conditions. The user should ensure that the equipment is not installed in location where it may be subjected to external conditions (such as high-pressure steam) which might cause a build-up of electrostatic charge on non-conductingsurfaces. Additionally, cleaning of the equipment should only be done with a damp cloth.
