J3/ J3C / J3CS MODULATING ELECTRIC ACTUATOR
Movement of the actuator is proporonal to input signal
Power is applied connuously. Movement of valve actuator is then controlled by an internally ed digital posion-
er and is proporonal to changes supplied in an input control signal. This input signal is typically 0-10VDC, or 4-
20mA. An output signal is supplied as standard providing closed loop control. Fails closed on loss of control signal
(or see conguraon opons below), but stays put on loss of external power.
Conguraon opons:
1) Closes on loss of control signal
2) Opens on loss of control signal
3) Stays put on loss of control signal (Fail freeze)
J3/ J3C / J3CS FAILSAFE MODULATING ELECTRIC ACTUATOR (same wiring as modulang version)
Combinaon of failsafe & modulang above:
Uses baery failsafe system and digital posioner to provide fail to safe posion funcon on loss of external power.

J3 & J3C Modulang Electric Valve Actuators
Make the live (L) or posive (+) connecons:
In a modulang valve actuator, the power is
permanently applied and NOT switched as in
an on-o or failsafe actuator.
Connect a live to pin 2 of the external power
Din plug, and to pin 1 of the posion conr-
maon plug.
Apply power to pin 1 of the posion conr-
maon plug for end of travel conrmaon.
This circuit is made around 5° ahead of the
nal closed posion.
Make the neutral (N) connecons:
1 x External power Din plug, pin 1
1 x Open conrmaon Din plug, pin 3
1 x Closed conrmaon Din plug, pin 2

ELECTRICAL CONNECTIONS
(We recommend only qualied electrical engineers make the connecons)

Control Signal Connecons (Centre DIN Plug)
Note: This Din plug is inverted to help prevent the possibility of the posion conrma-
on plug being connected to the control connecon, as doing so will irreparably dam-
age the DPS posioner. Such damage is not covered by the warranty.

Make the negave connecon from the negave output from your 4-
20mA (or 0-10VDC) device to pin 1 . Correct polarity of these control signal
connecons is crical so please double check.
❹
Make the posive connecon from the posive output from your 4-20mA
(or 0-10VDC) device to pin 2. Correct polarity of these control signal
connecons is crical so please double check.
If you are using the feedback signal from the J+J actuator posioner, make
the output connecon to the posive input to your 4-20mA (or 0-10VDC)
device to pin 3 .
The pin marked as earth (ground) on the control Din plug MUST NOT
BE CONNECTED to anything. This pin is used for an external reset
funcon and the posioner will not funcon correctly if any external
connecons are made to this pin.
The pin marked as earth (ground) on the control Din plug MUST NOT
BE CONNECTED to anything. This pin is used for an external reset
funcon and the posioner will not funcon correctly if any external
connecons are made to this pin.
