| Model J3 | |||||||||||||||||||||||||||||||||||||||
| Doc: J3-Cat/0I Jan 2008 | |||||||||||||||||||||||||||||||||||||||
| Feature rich J+J multi-voltage actuator with LED status light and plug & play accessories. | |||||||||||||||||||||||||||||||||||||||
| Quick guide to the J3's standard features : | |||||||||||||||||||||||||||||||||||||||
| Multi-voltage with auto-voltage sensing. V 12 ~ 24V AC or DC. H 110 ~ 240V AC or DC LED Status light to indicate operational status of actuator Electronic over-torque protection against valve jams Thermostatic anti-condensation heater | |||||||||||||||||||||||||||||||||||||||
| The effect of condensation is eliminated by an internal thermostatic anti-condensation heater that does not require a separate independent power supply. | |||||||||||||||||||||||||||||||||||||||
| New in 2008, the J3 range of electric actuators takes its highly successful predecessor, the J2 range, to the next level. With an all new, rugged weatherproof and anti-corrosive Polyamide housing, the J3 offers more user-friendly features than the J2, and introduces a highly visible LED status light. This visual indicator shows whether the actuator is operating 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 is quick and easy to install, with IS0:52II multi- flange mounting and a double square drive, allowing fast | |||||||||||||||||||||||||||||||||||||||
| mounting to ISO:52ll valves. There is no need to remove the cover to connect the J3 electrically, saving installation time. Using the external DIN plugs and external wiring diagrams supplied with the actuator, installations can be pre-wired. | |||||||||||||||||||||||||||||||||||||||
| Standard function for the J3 is power open, power close, stays put on power failure. New to the J3 are plug and play accessories -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 resetting functionality. These conversion kits are available as optional extras. The J3 is a very smart red box! | |||||||||||||||||||||||||||||||||||||||
| Manual override for emergency hand operation | |||||||||||||||||||||||||||||||||||||||
| 2 Volt free end of travel confirmation switches | |||||||||||||||||||||||||||||||||||||||
| IP65 weatherproof anti-corrosive and UV protected Polyamide housing | |||||||||||||||||||||||||||||||||||||||
| Protection against valve jams is provided by an electronic torque limiter, which autorelaxes the gearbox when activated, allowing the manual override to be selected to assist in clearing the jam. | |||||||||||||||||||||||||||||||||||||||
| Local visual position indicator ISO52II multi-flange mounting with double square drive All external electrical connections via supplied DIN plugs CE marked ISO 9000 manufacturer Failsafe and digital positioner plug & play kits available. | |||||||||||||||||||||||||||||||||||||||
| Status light functions: | |||||||||||||||||||||||||||||||||||||||
| Constantly lit LED If the actuator is operating correctly with no faults, the LED shows a constantly lit light. | The LED flashes with 2 blinks | The LED flashes on/ off When the actuator senses an impending valve jam, the electronic torque limiter is activated and on activation, repeatedly flashes the LED on and off. | |||||||||||||||||||||||||||||||||||||
