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 funcon of a J3C electric valve actuator is power open, power close. It stays put on external power failure.

Should the applicaon require that the electric actuator is sent to a pre-determined posion on loss of external power, the electric actuator

needs to be equipped with a system that can send the actuator to that pre-determined posion without the use of external power. In the

J3C, the BSR funcon conversion plug and play kit provides this funconality by providing an alternate power source (baery) to drive the

motor to the required posion. This funcon this creates what is known as FAILSAFE.

The inials BSR stand for Baery ‘Spring Return’ and use the industry recognisable phrase ‘spring return’ simply to describe the funcon 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 applicaon, 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 installaon of a plug and play funcon conversion kit that does not require a

change to the actuator’s external electrical connecon.

The user friendly BSR failsafe plug and play funcon conversion kit is quick and easy to install, and can be congured on installaon to send

the J3C electric actuator to either the closed posion (fail closed), or the open posion (fail open) on loss of external power.

HOW THE BSR SYSTEM WORKS

The BSR plug and play FAILSAFE funcon conversion kit comprises 2 x NiCad industrial rechargeable baery packs, a PCB which in simplisc

terms contains a system to trickle charge the baeries, to switch from external to baery power on the loss of external power and to iniate

LED ashing sequences, and a jumper to plug into the PCB.

Once installed, the baeries 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 baery power is drawn to send the actuator to the pre-determined failsafe posion, if not already in that posion at the moment

of loss of external power.

On resumpon 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 dierent from the posion seen at the moment of loss of external power.

J3C-140/300 BSR SAFETY & WARRANTY INSTRUCTIONS

Damage caused by non-compliance to these instrucons will not be covered by our warranty. It is essenal therefore that you read

all of these instrucons BEFORE installing or connecng the actuator.

SAFETY INSTRUCTIONS

J+J Electric actuators operate with the use of live electricity. It is recommended that only qualied electricians or people instructed

in accordance with electrical engineering, and familiar with local health and safety direcves, be involved in the connecon of

these actuators. It is strongly recommended that each actuator has its own independent fused power supply system to protect it

against the inuence of other electrical devices connected to the system.

WARRANTY INFORMATION

> Every J3C electric actuator is fully tested and set at the factory, they will not normally require adjustment on site.

>The J+J electric actuator range is guaranteed for 12 months from date of despatch from the manufacturer against all types of

manufacturing and material defects. Actuators that have failed due to faulty materials will be replaced without charge. The guar-

antee is limited to the replacement of the actuator only, as decided by our service department and no third party costs (e.g. la-

bour costs for removal/ replacement, producon down me, etc.) howsoever arising, will be entertained. Transport costs in-

volved in the return and replacement are chargeable.

> The guarantee is only valid if the actuator has been installed, operated and maintained strictly in accordance with these instruc-

ons, and that the actuator has NOT been disassembled, self-repaired, incorrectly re-assembled, suered damage caused by

shocks or mal-operaon, been supplied with inappropriate power supplies, used in condions outside its specicaons or work-

ing condions, or suered damage by pracces not in accordance with sound engineering pracce or common sense.

Step 1

Send the J3C electric actuator to the CLOSED posion.

Screw the hexagonal brass DPS circuit board support column

from the plasc bag in the DPS kit, into the actuator’s alumini-

um plate as shown in Photograph 6.

Step 2

Slide the DPS circuit board over the black plasc sha, ensur-

ing the spigot in the feedback gear aligns with the corre-

sponding slot in the plasc sha.

Ensure the plug and socket connecon between the main PCB

and the DPS PCB is rmly made.

Step 3

Secure the DPS PCB with the securing screw from the plasc

bag in the DPS kit into the brass hexagonal support column as

shown in Photograph 8.

Note:

These instrucons show a BSR failsafe system installed prior

to installing the DPS modulang system. This will create fail-

safe modulang funcon.

WIRING DIAGRAMS

We recommend a fused independent supply for each actuator and it is very important that the power supply earth connecon is made to prevent

the current-free voltage on the non-live pin prevenng 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 posion conrmaon switches are volt free and can have a dierent voltage applied than the power supply voltage e.g. 220V/1ph power

supply, 24VDC for posion conrmaon. For ease, the schemac below shows the same voltage for both power and posion conrmaon. See

notes at the boom of this page regarding use of the volt fee contacts (end of travel conrmaon).

Funcon opons with the J3C electric actuator:

J3C ON-OFF ELECTRIC ACTUATOR

Standard funcon 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 posion on loss of external power.

Power open, power close, fails to pre-set ‘safe’ posion on

loss of external power using internal industrial trickle charged

rechargeable NiCad baery. Can be set to fail close or fail

open on loss of external power. The failsafe electric actuator

moves to the posion command applied at the me external

power is restored.

J3C MODULATING ELECTRIC ACTUATOR

Movement proporonal to input signal

Power is applied connuously. Movement of valve

actuator is then controlled by an internally ed

digital posioner 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), 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

IMPORTANT NOTES

EXTERNAL POWER SUPPLY/ COMMAND SIGNALS, AND POWER SUPPLY SIZING

The J3C electric actuator is designed to have connuous (not pulsed) external power applied at all mes. It’s internal thermostac an-condensaon

heater uses the external power to funcon, so switching o the power at end of travel switches this protecon o. Damage caused by the eects of

condensaon is not covered by our warranty as we provide protecon against it as standard. It is imperave that the power supply has sucient

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 conrmaon signals to switch o the command signals is that as they are set around 5 degrees ahead of

the nal motor stop posion (fully open, or fully closed), if used to switch o the power, the valve will not reach the nal motor stop posions.
