SSi recommends 1.5 scfh. However, anywhere from 1 – 2 scfh is acceptable.
The bowl filter leading into the unit contains a filter element (p/n 37051) that can be replaced when it becomes dirty.
These are factors that go into the calculation for determining the %Carbon. Manually adjusting them will have a direct effect on the %Carbon being calculated. Contact SSi for more information.
For RS485 Communications:
- Wire to the terminals 1561 and 1571 inside the MZA.
- On the MGA screen interface, go to the Menu and log in with the number 2.
- Select “Communications and source setup” > “Atmosphere/Temp sources”
- Here you can edit to add your Probe Temp/mV Instrument or Furnace temp Instrument.
- When you have selected the appropriate device, edit the Probe Temp/mV instrument address or the Furnace temp instrument address.
- Call SSi at 513-772-0060 for a Code of the Day login number.
- Log in with the code.
- Select the “Factory use only” option.
- On the following screen select “Set Instrument Type.”
- Set the Nitrider Calculations option to Enable.
- You will then need to cycle power to have the correct Calculations page displayed.
- First, make sure you have the Zero and Span gas tanks hooked up to the correct calibration ports on the side of the MZA.
- On the Interface go to Menu and log in with the number 2.
- Select “Automatic Calibration setup.” You will see the options to set the Auto calibration to YES or NO.
- Select “YES” to set up your desired calibration purge and intervals.
SSi recommends that the MZA be mounted fairly close to the source it is sampling. It can be further away, but a longer sample tube increases the likelihood of leaks or contaminants.
The incoming pressurized gas goes through a small fixed orifice inside the analyzer, which should require between 20 and 50 psi to maintain proper flow.
- Go to the Menu and log in with the number 2.
- Select “Automatic Calibration set up” then change the Auto Calibration from YES to NO. That will clear the Auto Calibration alarm banner.
**It is important to note WHY you were getting the alarm, to make sure that you were getting adequate flow and the calibration was able to complete successfully.
- Go to the Menu and Log in with the number 2.
- Select “Edit Active Zones.” From this screen you can deactivate a zone and turn off the corresponding pump.
The MZA has the ability to analyze up to eight zones. Note that this requires two Sample Pump Boxes (p/n 13662).
