ACTUATOR MOUNTING
BEFORE START WORKING:
SAFETY REGULATIONS:
- Disconnect mains!
- Prevent reconnection!
- Test for absence of harmful voltages!
- Cover or close nearby live parts!
Mounting
1:
Drive coupling
upwards by hand
6:
Use the commission function
to complete the actuator
mounting, detailed on the
bottom of Page 5.
2:
Position Jam nuts as per reference
drawing and lock nuts together.
3:
Drop Actuator onto
Valve assembly and
tighten lock nut.
4:
Extend
Actuator by
hand and lift
valve stem to
meet Actuator
coupling.
5:
Thread the valve stem
into the coupling until
the jam nuts meet the
coupling. Lock the
upper jam nut against
the coupling. Lock the
second jam nut against
the upper nut.
When mounting an actuator on a valve, always
use the hand wheel! Motor operation during
mounting may cause injuries and damage to
actuator and valve!
FOR MOUNTING THE ACTUATOR, THE VALVE
MUST BE IN FULLY CLOSED POSITION!

GENERAL SAFETY
ILEA actuators are built with state of the art technology and
are safe to operate with commonly accepted electrical safety
precautions. ILEA Actuators can also produce significant
linear forces and should only be operated when connected
to a control valve unless otherwise instructed. Fingers should
not be anywhere near the moving parts of the valve and
actuator assembly while power is connected.
Operators should be trained, read the user manual and have
a good understand of the actuator’s function and operating
capabilities.
The wiring termination should be verified before
commissioning commences.
If the actuator was purchased together with a control valve
the actuator will be precalibrated to the valve’s stroke and
there will be no other requirement than applying the correct
power supply and control signal.
The standard control signal is 4 – 20 mA where a 2-way valve
is closed at 4mA and fully open at 20 mA. This standard
configuration would be depicted on the product label for

Proceed
ONLY AFTER
following set-up and
wiring on Pages 4 & 5.
