J3C FAILSAFE ACTUATOR WITH BSR PLUG & PLAY KIT OPTION
J3C MODULATING ACTUATOR WITH DPS PLUG & PLAY KIT OPTION
WHAT IS THE BSR (BATTERY‘SPRING RETURN’) FAILSAFE CONVERSION KIT?
The standard funcon of a J3C electric valve actuator is power open, power close. It stays put on external power failure.
Should the applicaon require that the electric actuator is sent to a pre-determined posion on loss of external power, the electric actuator
needs to be equipped with a system that can send the actuator to that pre-determined posion without the use of external power. In the
J3C, the BSR funcon conversion plug and play kit provides this funconality by providing an alternate power source (baery) to drive the
motor to the required posion. This funcon this creates what is known as FAILSAFE.
The inials BSR stand for Baery ‘Spring Return’ and use the industry recognisable phrase ‘spring return’ simply to describe the funcon it
achieves - but there are no mechanical springs in the kit. Providing an alternate power supply (a) allows the same torque output actuator
that is used for an on-o actuator in this applicaon, as the actuator does not have to overcome the extra torque the springs add in a true
mechanical spring return electric actuator, and (b) allows the installaon of a plug and play funcon conversion kit that does not require a
change to the actuator’s external electrical connecon.
The user friendly BSR failsafe plug and play funcon conversion kit is quick and easy to install, and can be congured on installaon to send
the J3C electric actuator to either the closed posion (fail closed), or the open posion (fail open) on loss of external power.
HOW THE BSR SYSTEM WORKS
The BSR plug and play FAILSAFE funcon conversion kit comprises 2 x NiCad industrial rechargeable baery packs, a PCB which in simplisc
terms contains a system to trickle charge the baeries, to switch from external to baery power on the loss of external power and to iniate
LED ashing sequences, and a jumper to plug into the PCB.
Once installed, the baeries are constantly trickle charged whenever external power is applied, maintaining them at full charge so that pow-
er is available to draw at the moment the external power fails. When the external power fails, the BSR PCB switches from external to internal
power, and baery power is drawn to send the actuator to the pre-determined failsafe posion, if not already in that posion at the moment
of loss of external power.
On resumpon of external power, the J3C failsafe electric actuator will respect the command signal being applied at the moment the exter-
nal power is restored. This may be dierent from the posion seen at the moment of loss of external power.

WIRING DIAGRAMS
We recommend a fused independent supply for each actuator and it is very important that the power supply earth connecon is made to prevent
the current-free voltage on the non-live pin prevenng the actuator working. This current-free voltage disappears as soon as the motor runs, but
in non-earthed systems it can stop the J3C from working.
The posion conrmaon switches are volt free and can have a dierent voltage applied than the power supply voltage e.g. 220V/1ph power
supply, 24VDC for posion conrmaon. For ease, the schemac below shows the same voltage for both power and posion conrmaon. See
notes at the boom of this page regarding use of the volt fee contacts (end of travel conrmaon).
Funcon opons with the J3C electric actuator:
J3C ON-OFF ELECTRIC ACTUATOR
Standard funcon is power open, power close. Stays put on
loss of external power. Power remains on at all mes.
J3C FAILSAFE ELECTRIC ACTUATOR
Fails to pre-set posion on loss of external power.
Power open, power close, fails to pre-set ‘safe’ posion on
loss of external power using internal industrial trickle charged
rechargeable NiCad baery. Can be set to fail close or fail
open on loss of external power. The failsafe electric actuator
moves to the posion command applied at the me external
power is restored.
J3C MODULATING ELECTRIC ACTUATOR
Movement proporonal to input signal
Power is applied connuously. Movement of valve
actuator is then controlled by an internally ed
digital posioner and is proporonal 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 conguraon opons below), stays put on
loss of external power.
Conguraon opons:
1) Closes on loss of control signal
2) Opens on loss of control signal
3) Stays put on loss of control signal
IMPORTANT NOTES
EXTERNAL POWER SUPPLY/ COMMAND SIGNALS, AND POWER SUPPLY SIZING
The J3C electric actuator is designed to have connuous (not pulsed) external power applied at all mes. It’s internal thermostac an-condensaon
heater uses the external power to funcon, so switching o the power at end of travel switches this protecon o. Damage caused by the eects of
condensaon is not covered by our warranty as we provide protecon against it as standard. It is imperave that the power supply has sucient
capacity to drive the J3C electric actuator. Ensure that safety factor of 3 is used to cover inrush on start-up, and for increased draw over me as the
brushed DC motor wears.
Another issue with using the end of travel conrmaon signals to switch o the command signals is that as they are set around 5 degrees ahead of
the nal motor stop posion (fully open, or fully closed), if used to switch o the power, the valve will not reach the nal motor stop posions.
J3C FAILSAFE MODULATING ACTUATOR
Combinaon of failsafe & modulang kits above: Uses baery failsafe system and digital posioner plug and play funcon conversion kits to provide fail to
safe posion funcon on loss of external power in a modulang applicaon.

MOUNTING THE J3C ACTUATOR TO 1/4 TURN VALVES
J3C Actuators have mounng facilies in accordance with ISO:5211 and DIN:3337 allowing them, in many cases, to mount directly onto similarly compliant
valves without the need for a mounng kit (bracket and drive adaptor/ connector). The main advantages of direct mounng the actuators is to greatly assist in
ensuring concentricity of the actuator output drive with the valve stem which eliminates side loadings (which result in increased wear on the valve stem and
seals), reducing the eects of backlash in the drive train as there are fewer parts connected, and allowing valves to be part dismantled for installaon into the
pipe without disturbing the valve to actuator connecon.
The drive being inserted into the actuator’s female output drive must NOT be longer than the maximum depth of the female drive when the
assembly is bolted together. Resulng damage to the actuator and assembled components due to this assembly error will not be covered by our
warranty.

WEATHERPROOF RATING
The J3C electric actuators have an ingress protecon rang of IP67, which gives them total protecon against
almost all kinds of weather and allows the actuator to be submerged under less than 1m of water for no more
than 30 minutes. However, it cannot withstand being hosed down or pressure washed, or deluged in water.
If the J3C is to be exposed to hosing down or pressure washing, a plasc bag must be rst put over the J3C
actuator to protect it from the direct hosing down. Even in these circumstances, do not pressure wash the
plasc bag close up.
Damage caused by water ingress is therefore not normally covered by the warranty.
RECYCLE AT END OF LIFE
J+J is commied to the protecon of the environment.
Please remember at end of life to dispose of responsibly and if the facilies are available recycle.
