Questions on building config file for v6.2.0 firmware

[Anonymous user]

Hello,

I am currently working on building our general config for the new v6.2.0 firmware. I have a few questions about the "SmartUPS/Matrix" section.

1. Does the UPSOverride portion need to be set to the UPS's serial number in order for the information in this section to be applied?

2. Can someone please explain the Low Battery Duration vs the Basic Low Battery Duration? My understanding is that the Low Battery Duration should be set to the number of remaining runtime minutes left before the "Low Battery" SNMP trap will be sent out.

     If this is correct, is there anything else that this parameter will control?

3. I am also not familiar with the PowerChute Shutdown Parameters for "Maximum Required Delay" & the Username/password (doesn't look to be the same as the login user/password). Any explanation on these would be greatly appreciated!

Hi Ryan,

Here is some feedback.

1.) We sort of have this explained here for another section we use override. I'll get it updated to cover the UPS portion. http://www.schneider-electric.com/support/index?page=content&country=US〈=en&locale=en_US&id=FA156136 I'll have to confirm with the specific UPS model if you can share it but usually, the same principle explained in the article would be applied to UPS output voltage and sometimes output frequency and transfer ranges (if tied the UPS output voltage setting).

2.) Low battery duration AKA low battery signaling time is when the UPS signals it has a low battery. So you're right in your explanation. Basic Low Battery is if you're doing something special with Network Management Card (NMC) and also have a device connected to a UPS serial port and I think it is a legacy setting carried over as it does not work with some UPS models today as it used to with legacy items. Low battery state of a UPS is tied to other types of events like when the UPS starts getting close to this value and your runtime is low, you may receive messages saying batteries discharged or the batteries are too low to support the load. It is also the last point in time that the Network Management Card will send a message to PowerChute Network Shutdown clients to begin a shutdown, if they haven't already.

3.) Are you using PowerChute Network Shutdown? If so, the maximum required delay is explained a little bit here -> What does the Force Negotiation setting achieve in the Network Management Card? | FAQs | Schneider E... After the Network Management Card polls all of the PowerChute clients, it tries to determine the max amount of time any one client needs to shutdown (like to run a command file or something). The username/password pertains to the username and password tied to PowerChute Network Shutdown registration. It must be set here and also be the one you enter to install PowerChute Network Shutdown on a system. It is used as an authentication mechanism along with the authentication phrase you see on the screen. (Historically, PowerChute just required the administrator username to be the same on the Network Mgmt Card and PowerChute but now the new NMC2 firmwares support multiple users and types so we add to add a field for the user to specify it or PowerChute won't work and establish communication properly). If you're not using PowerChute Network Shutdown, then you can just leave this be.

Hope that helps. Let me know if you have any questions and can also share your UPS model. About->UPS should show you what I need within the NMC interface.

Thanks so much! That was a lot of help!

Here is the UPS info:

Model:	Smart-UPS X 1500
SKU:	SMX1500RM2U
Serial Number:	AS1351115090
Firmware Revision:	UPS 09.1 (ID20)

We have hundreds of UPSs that we use, so this is just one example.

One more question, what does the sensitivity change? If set to a lower value, is this just to ignore any voltage spikes or drops that quickly return to the indicated window?

We currently have ours set to normal:

UPSName=APC UPS

UPSOverride="AS1351115090"

OutputUpperVoltage=127

OutputLowerVoltage=106

Sensitivity=Normal

LowBatteryDuration=15

ShutdownDelay=90

ReturnDelay=0

SleepTime=000

BatteryDate=12/19/2013

AudibleAlarm=enabled

SimpleSignalShutdown=disabled

SimpleSignalLowBatteryDuration=120

SelfTestSchedule=OnStartUp14Since

LCDLanguage=English

Hi Ryan,

For SMX1500, I believe we removed the restriction on OutputUpper/Lower voltages you see there but at one time, UPS Override protected those. I am going to look into it further to see if I can get a list for different UPSs and what it protects and document it and then report back. This UPS does not have a frequency setting or output voltage setting so I don't know what else it'd protect for this specific example/UPS.

On sensitivity, we have this article here What are the different sensitivity settings of a Smart-UPS? | FAQs | Schneider Electric US. It is usually a setting that determines how sensitive a UPS is to minor power fluctuations which is something commonly adjusted when using an input power source like a generator. Typically, you'd leave this at high unless you experience frequent transfers to battery, like during a generator test.

Thanks a lot!

Hi Ryan,

On this one, I confirmed:

On SMT/SMX/SURTD/SRT UPSes, the following are protected by UPSOverride:

- RatedOutputVoltage

- OutputFrequencyRange

On older SU, SUA, SUM, SURT, SURTA, Symmetra UPSes, the following are protected by UPSOverride:

- RatedOutputVoltage
