XNX Gas Detector Calibration details discussion. So I’ve just installed this ammonium gas detector transmitter and we’re standing here with a big ammonium tank. We got the level here inside, of course, NH three. So I thought I’ll show you some features of it if you’re considering getting one. It’s a Honeywell X and X right now. I’ll show you the light. Turn on the light so you can see that it’s zero Ppm and it’s measuring NH three. To reset the fault alarm. There are no alarms, I guess. Well, you can see you have two levels here the first level and the second XNX Gas Detector Calibration.

I believe the second level is when the alarm goes off, I connected it to the relay. You can also use four to 20 milliamps signal out to the Plc, but this is just using an off switch. That is when you get over the second level. I believe in Ppm of NH three. Then the alarm goes off and then you have to retract back to number one. When number one is accomplished, when you’re down below one, then it’s possible to reset it here. Otherwise, if you don’t reset it here on the local place on the local here, then it’s still available in the control system to the operators.

So you got the sensor here and you get a different intake here. You have four possible cable intakes and you can hopefully just unscrew this one. I’ll show you the inside. So this is the inside and you got the voltage. The supply runs on 24 volts plus and minus here. And then also I’m using guard sort of NNO. And so I connect 24 to the common. And then when a guard goes active, it closes the switch and activates the alarm to the control system. It’s just located far away.

So that’s pretty much it. This connection here for the T before is for the reset of the local reset button. And it’s pretty self-explanatory. You got the relays here and you got the four to 20 million. Here is the old signal here hard. You can’t press here. You have to have a sort of a magnet. This is a magnet that comes with the package and the passcode has to read the manual. So you can also use Modbus. But here we’re using a relay. Since we don’t have an output for analog input control and navigation is pretty self-explanatory. XNX Gas Detector Calibration.

Regarding the password, it looks like it’s four zeros for both the routine maintenance and technician and password admin. It’s the same. So let’s see if we can get in four0 and enter calibrate configure. Let’s try that one-like language. I’m happy with the English set time and date. Why not? That’s okay, I’ll click cut next. Here we have the limits. You can set them in ppm. 200 is Max and you got the levels $1500. So what else we got? Latching, non latching set units, volume milliamps levels, gaps, calibration interval relay options.

It’s working, so I won’t change it. I will show you later. Okay, so that’s pretty much it looks like you can lock it. Also, configure security. I won’t go there. I don’t want to lock it. So let’s try it. And now we have a little bit of ammonia here. Let’s get it close, see if we get some reading and nothing yet. But I will press here on the bottle and there we have it. So there we got the alarm. I was just getting some fuse up here.

So now we have an alarm in the control room that tells us that we have a leak here or something and I turn off, put back the lid here and it’s going down. So I’ll do a fast sequence of this. But when it comes down to the 50, then it’s possible to push that button. So now we can reset it. But I thought I would show you how it looks on the screen inside the control room. So let’s go and check that out. The alarm shows you the picture of it in the operating system.

FAQ: XNX Gas Detector Calibration

How to perform gas calibration on the XNX?

  1. Access the programming menus to set XNX Gas Detector Calibration.
  2. Once in the menus select the Calibrate menu and press the (✓) key.
  3. Now simply mark the Gas Calibration key and press the (✓) key option.
  4. Apply zero gas; when the zero gas reading is stable press the (✓) key to confirm zero calibration.
  5. So the zero calibration is complete without error, then the transmitter device shows a Zero Passed screen.
  6. Now click the (✓) mark to perform Span Calibration, and choose (✖) to avoid Span Calibration. then go back to the menu.
  7. Enter the concentration of the span gas by using the (+) or (-) switches to increment or decrement the values. Click on the tick mark (✓) to accept the value and go to the next digit. Don’t stop until all marked.
  8. It is time to go with span calibration gas; as now wait the right time for (✓) to confirm span calibration.
  9. If the span calibration is successful, the transmitter will display the Span Passed screen.
  10. So, you can be ready to promote the area “Exit with Inhibit Off”, “Exit with Inhibit On” or “Do not exit”.

Does Soft Reset on the XNX all look optima or Excel signal?

  1. Access the programming menus.
  2. When you marked CALIBRATE menu option than simply press the (✓) button.
  3. Scroll and select the SOFT RESET option.
  4. Press the (✓) key to confirm the reset.
  5. After completing the above option then Soft Reset press for  (✖) key exit option.

Performing a Soft Reset will restart the sensor. The boot-up cycle for the Optima or Excel sensor will take about 2 minutes. Hope you get an idea on XNX Gas Detector Calibration.

We will be happy to hear your thoughts
