J3
Status light functions:
The LED flashes on/ off
When the valve actuator senses
an impending valve jam, the
electronic torque limiter is
activated and on activation,
repeatedly flashes the LED on
and off.
Constantly lit LED
If the electric actuator is operat-
ing correctly with no faults, the
LED shows a constantly lit
light.
The LED flashes with 2 blinks
If the actuator has been left in
‘manual’ mode, the actuator’s
motor runs but doesn’t drive
the output shaft. After a pre-set
time, the actuator knows that
as the torque limiter has not
activated and that the motor is
running, it must be in manual.

the manual override to be se-
lected to assist in clearing the
jam.
The effect of condensation in
the
J3
electric actuator is
eliminated by an internal ther-
mostatic anti-condensation
heater that does not require a
separate independent power
supply.
Standard function for the

electric valve actuator
is power open, power close,

failure.
New to the
J3
electrical actu-
ators are plug and play accesso-
ries –the function can be
changed to either failsafe or
modulating by fitting the new
plug and play conversion kits.
The modulating kit has the new
digital positioner that offers
auto-calibrating and self reset-
ting functionality. These conver-
sion kits are available as option-
al extras.

multi-voltage electric actuator
with LED status light and plug & play accessories.
New in 2008, the
J3
range of
electric actuators takes its high-
ly successful predecessor, the J2
range, to the next level.
With an all new, rugged weath-
erproof and anti-corrosive
Polyamide housing, the
J3
valve actuator offers more user
-friendly features than the J2,
and introduces a highly visible
LED status light.
This visual indicator shows
whether the actuator is operat-
ing correctly, or has tripped out
either by its electronic torque
limiter, or has been left in
‘manual’ mode.
Site operators are no longer
left with the ‘valve or actuator?’
question when an actuator
doesn’t respond to a signal.
The
J3
rotary electric actua-
tor is quick and easy to install,
with IS0:5211 multi-
flange mounting and a double
square drive, allowing fast
mounting to ISO:5211 valves.
There is no need to remove the
cover to connect the
J3
electri-
cally, saving installation time.
Using the external DIN plugs and
external wiring diagrams supplied
with the actuator, installations
can be pre-wired.
Protection against valve jams is
provided by an electronic torque
limiter, which auto-relaxes the
gearbox when activated, allowing
