¡ñ EROK EK/EKQ series actuator adopts a special LCD developed for the display of actuator, the vivid and legible identification signs make the user observe the status display of valve position, moment and function of the actuator very easily, the unique LCD with background illumination system provides high visibility under all the lamplight conditions. Meanwhile, it provides three LED (green, yellow and red) indication lamp for valve position to make the user know the status of the actuator at a glance.
¡ñ Site operation avoids conventional knob thru shaft, local knobs all adopt switch type Hall sensor with magnetic steel inductive control, therefore, they work reliably without the environmental effect. Hall switch has very quick and very accurate response speed without life limitation of the switch.
¡ñ High integration density, low power dissipation and display support in case of AC power failure. It is designed by adopting superlarge scale analogue and digital hybrid integrated chip to constitute SOC control system. Making the product have fewer peripheral electronic elements, higher electronic reliability, more powerful functions and lower electronic power consumption, thus can fully satisfy the "green and environment-friendly" requirements for the design of modern electronic products. The built-in backup battery of actuator starts to work once the main power fails to ensure that the user still can see the display of many statuses on the LCD of the actuator during manual operation after power failure, but it does not provide LCD's backlight and indication lamp for valve position. The battery has a voltage of 9V and its shortest service life is 5 years.
