Recycling and disposal
Most limit switch parts can be recycled if sorted
according to material. See the list below for materials.
In addition, separate recycling and disposal instructions are available from us. A limit switch can also be
returned to us for recycling and disposal against a fee.
1.6
Safety precautions
CAUTION:
Do not exceed the permitted values!
Exceeding the permitted values marked on the limit
switch may cause damage to the switch and to equipment attached to the switch and could lead to uncontrolled pressure release in the worst case. Damage to
the 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.

MOUNTING AND INITIAL SET-UP
2.0.2
2.0.1
Mounting to ISO-NAMUR style
actuators
Start with the actuator in the closed position. Loosen
the drum fastener enough to allow the rings to rotate.
Lift and rotate the lower ring until the stainless steel
rivet is in front of the lower target on the function module. Rotate the actuator to the open position. Lift and
rotate the upper drum trigger/indicator until the stainless steel rivet is in front of the upper target on the function module. (Flowline models: Then lift and rotate the
drum’s flow line indicator to align with the flow line indicator on the function module.) Securely fasten the drum
fastening screw. To adjust simply loosen screw and
adjust triggers and indicator to suit your application.
LEDs will energize or de-energize when powered, indicating sensor status.
1. Place the Namur coupling into the slot of the actuator
shaft. Then engage the inner drum “tophat” onto the
coupling. Slide both of the adjustment rings over the
drum. Then complete the assembly by placing the
flow line drum indicator on top and secure with the 6
mm drum fastener. Ensure the assembly is centered.
2. Place polycarbonate cover over completed trigger/
indicator assembly. Fasten to actuator with supplied
cover fasteners. This step insures proper spacing of
the module from the trigger assembly.
Namur size 1 and 2
Attach function module using fasteners provided and
tighten down securely.
Namur size 3 and non-Namur applications
Attach spacer or bracket to actuator with fasteners provided and tighten securely. Attach function module to
spacer or bracket and tighten securely.
Note: The top of the drum should be at the same
height as the top of the function module.

1. ECN Series: Remove function module cover. Attach
wires to accessories and/or signal circuit as indicated on wiring diagram on next page. Replace
cover and securely tighten cover screws.
Note: Ensure adequate drainage of wiring conduit to
prevent water contamination inside enclosure.
2. ECG Series: Attach appropriate cordsets to quick
disconnect fittings.
