MMQ stands for Month/Month/Quarter. It refers to LDAR rules that change a component’s monitoring schedule to a quarterly basis only after not leaking for two consecutive months.
Chateau assigns each of the phases in this MMQ a special M21Why:
| Term | Definition |
|---|---|
| M1 | The first of the two months. Either initially or after a leak has been found. |
| M2 | The month that falls after a month when the M1 is passing. |
| mmq | The quarterly event that occurs after a passing result on an M2 Inspection. |
Examples
| If an Inspection is… | The Inspection | The NEXT Inspection will be… |
|---|---|---|
| On a Brand New Comp (M1) | Passes | M2 |
| On a Comp after any leak is found (M1) | Passes | M2 |
| On an M1 | Passes | M2 |
| On an M2 | Passes | mmq |
| On an mmQ | Passes | mmq |
| ANY TIME an inspection (M1, M2 or mmQ) | Fails | M1 |
The MMQ Phase is slightly different from the NextM21Why. Chateau defines and maintains the MMQ Phase on any MMQ Component even when the component is not scheduled to be monitored.
For instance:
-
An MMQ Comp is monitored as an mmQ.
-
Because it is in the mmQ Phase.
-
It Leaks.
-
Its Frequency is still MMQ.
-
Its Next M21 is BLANK (because it is done for the current period)
-
BUT…Chateau changes its MMQ Phase to M1 immediately so you can see on the Home Screen, component grid, and the Tag View that the leak was recognized and the change has been made.
- The Schedule will not show the M1 scheduled until the first of the next month, but the Home Screen will show the M1 in the MMQ Phase immediately.
There are three different events that will “reset” the MMQ phase to M1:
- A failing M21 inspection
- Component Initialization (when a new equipment model is installed)
- Missed inspection—if the component is currently in the M2 phase.
- If a component is in the mmQ phase, then a missed inspection will NOT reset the phase back to M1. The component will be rescheduled the consecutive month of the quarter. This will continue until the inspection is performed.
MMQ Group controls which month of the quarter the mmQ monitoring is scheduled in.
You can control when the mmQ Monitoring is done by setting each MMQ component to one of the following groups:
| Means the mmq monitoring will be performed in… | |
|---|---|
| Month 1 | The first month of each quarter. |
| Month 2 | The second month of each quarter. |
| Month 3 | The third month of each quarter. |
| None | As due at the end of the quarter. The inspection can be performed ANY month of the quarter. |
The setting is a component property that you edit in the Tag View. Most likely you will identify a group of MMQ components and do a Multi-Edit.
| Tag | Frequency | NextM21Why | MMQ Phase | MMQ Group | If you see this in Component grid, it means… |
|---|---|---|---|---|---|
| 1 | MMQ | M1 | M1 | Month 1 | M1 Phase. First month of the quarter. Due in the current month. If an MMQ inspection in Month 1 does not get done in January, Chateau reports it as a missed inspection and schedules the mmQ for the next month, February. But Chateau keeps it in the Month 1 group. A missed inspection will reset M2 back to M1 but does not disturb the MMQ group. |
| 2 | MMQ | M1 | Month 2 | M1 Phase. Already done for the current month (which is why the NextM21 is blank). When it will be done for the mmQ that will happen in the second month of the quarter. After some experience, you will see this component must have leaked when it was monitored earlier in the current month. If you can see that, you are an MMQ Guru! | |
| 3 | MMQ | M2 | M2 | Month 3 | mmQ phase will be done in the third month of quarter. This is scheduled for the current month as an M2, which means it was monitored LAST month as an M1 and DID NOT LEAK. Can you see that? |
| 4 | MMQ | mmq | Month 2 | mmQ will be done in the second month. Can you see this record means this component was monitored already this month as an M2, was not leaking, and has been advanced to the mmQ phase? | |
| 5 | MMQ | MMQ | mmQ | mmQ will be due at the end of the quarter. The inspection can be performed at any point during the quarter. |
