1.6 Safety precautions

2 MOUNTING AND INITIAL SET-UP

2.0.1 Mounting to ISO-NAMUR style actuators

Attach 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 entire Vis-ual Indicator/Trigger Assembly and tighten only a cou-ple 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 Assemblyas possible. When the bottom of the Visual IndicatorCover is flush with the base of the Function Module,slide the Visual Indicator horizontally until the CoverAlignment Ribs fit completely into the mating grooveson the Function Module. Tighten the Visual IndicatorCover securely to the actuator with fastners provided inthe mounting kit.

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 enclosure

EG series:

Control and solenoid wires are connected to theEclipse Function Module via M12 micro-connectors asper information 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:EG44___ Entity Parameters: Ui (Vmax) = 22 Vdc; Ii (Imax) = 120 mA ; Ci = 98 nF; Li = 1.56 mH; Pi = 2.0 W

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.
