How to Calibrate the Bray Sequence 70 NXT REV2 Valve Actuator
In this post, we will discuss the steps taken to ensure this process goes smoothly and provide a detailed walkthrough of the steps needed to complete this calibration procedure. With the help of the tutorial from the YouTube video, we will go through each step and explain what needs to be done and why.
The first step in configuring a closed position is to establish the valve closed position. When manually rotating the actuator, note the camshaft slot may be offset by 90 degrees depending on manufacturing date. The red and green cams must then be adjusted to the designated locations that will activate their respective valve position lights. The camshaft set screw should be tightened once the adjustments are finished.
Verification of the configuration can be performed by testing various positions using a signal generator that matches the input mode selected. During testing, the potentiometer voltage should not be less than 0.1 volts or more than 3.1 volts. Additionally, the LED display settings should be adjusted and then auto-calibrated. When complete, verify the potentiometer voltage is less than 3.6 volts; if not, rotate the actuator towards the closed position until it meets this criterion.
FAQ
Q: What are the steps to correctly calibrate the Bray Series 70 NXT REV2 Actuator?
A: The steps to properly calibrate the Bray Series 70 NXT REV2 Actuator include manually rotating the actuator to the proper closed position using the lid and don't position indicator. You must also adjust the red cam to the location that activates the red valve position light and adjust the black potentiometer to the location that provides a potentiometer voltage DC between 0.14 and 0.3. When the actuator is manually rotated to the proper valve open position, you must verify that the potentiometer voltage is less than three point zero six. Finally, once the green cam is adjusted to the location that activates the green valve position light, auto calibration can be initiated. All LED display settings should also be tested using a signal generator that matches the input mode selected, while verifying that the potentiometer voltage never goes below 0.1 volts or above three point one volts. Having followed the steps within this video, we have successfully calibrated a Bray Series 70 NXT REV2 Actuator and familiarized ourselves with its features.
We now have a device that can be utilized for the most efficient operation possible.
