Hey guys,
Ik heb een APC Smart-UPS 1000VA USB & Serial 230V, APC staat er om bekend zo snel mogelijk je accu's om zeep te willen helpen, nou heb ik op het internet wat oplossingen gevonden om de voltage naar beneden te krijgen, via de APC test tool heb ik geen prog optie. Ik zou hem graag op 27.4v zetten, hij zegt binnen de APC access tool dat die nu op 27.7v staat, meet ik daarentegen op de accu terminals krijg ik 14V, ik heb de onderstaande accu's, mss kunnen deze accu's er wel tegen (max 15v), maar kan me ook voorstellen dat ik nog steeds de boel aan het slopen ben, dingen zouden 5 jaar mee moeten kunnen, kan me ook voorstellen dat APC de party aan het verkorten is voor me
Moet ik me druk gaan maken om de voltage te verlagen, of kom ik met deze accu's er mee weg ?
Heb inmiddels ook een 12cm 12v/0.1a fan aan de zijkant geplakt, ding werd tijdens de kalibratie 40 graden was 35 in standby, nu met fan over de standaard gaatjes 20 graden, zal de levensduur wel bevorderen.

- Float Voltage verlagen
- UPS blijft zelf 27.7v zeggen
- 100% accu
- Voltmeter op de accu's
- Range 0=maximum gain, FF=minimum gain.

Y (antwoord SM)
1 en 1 (na 2 sec, even mee spelen antwoord PROG)
B (battery float voltage)
- = hoger voltage accu (klinkt raar maar je verhoogd de gain ~0.10v.)
+ = lager voltage accu (klinkt raar maar je verlaagd de gain ~0.10v.)
R (save of return)
Y (antwoord SM)

- Runtime verlengen dmv extra (fictief) accu-packs in software
- Controleer de waarde met een normale load

EDIT De site waar ik juist men procedure om voltage vandaan haalde was offline, wellicht wel handig ook voor andere om de hele procedure hier te plaatsen.
Note that APC has many different firmware revisions for their Smart-UPSs (as opposed to the firmware in the SmartSlot devices!), and the features available in Smart Mode vary. My SUA1000XL has firmware Rev. 631.3.D
Remove any SmartSlot card from the UPS. This might be a Network Management Card such as a AP9606, AP9617, AP9618, AP9619, or an Environmental Monitoring (EM) card. Just removing the two retaining screws and pulling it out of the chassis 1" is sufficient to disconnect it. While the official APC recommendation is to "Brain Dead" the unit before removing or installing SmartSlot cards, many people routinely change them hot (with the UPS ON), and that's what I do.
Use the Serial port. Because the SmartSlot cards must be removed, no networking is available, so you have to use the serial connection (or, perhaps, the USB connection if your Smart-UPS has one, but I haven't tried that).
Connect the Smart-UPS serial cable to the UPS & PC (or terminal emulator, or, I suppose, a real terminal if you have one ). In my case, the Smart Signalling 940-0024C (black) DB9xDB9 serial cable. No, you can't use a straight-through or null-modem cable. Disable COM-port apps. If using PowerChute, or another UPS Service, disable it. The terminal program must have exclusive control of the COM port. Figure out which port you're using, if there's more than one. I've read at least one report than a USB<->Serial converter does not work for this procedure. Use a terminal program, such as HyperTerminal that's bundled with versions of Windows. Setup parameters are 8-N-1 (Google what that means, (2400bps, 8N1, no flow control) if you haven't used a terminal program before. HyperTerminal is not a very good terminal program, but it will suffice.). Flow control is variously recommended to be "None" or "Xon/Xoff". I was successful with "None", so I didn't try "Xon/Xoff".
Test the setup. If everything is correct, you should be able to type a capital 'Y' (that's <Shift+Y>) and the terminal should display "SM": the UPS is now in Smart Mode. Occasionally, I've had to type 'Y' twice to get a response.
As a double-check, type a capital 'A'. Otherwise known as <Shift+A>. The UPS should beep and light up all front-panel LEDs for a couple of seconds. The terminal may display "OK".
Enter PROG mode by typing "1" followed by "1" again after two seconds. IF you pulled the SmartSlot card(s) out, and IF you got the timing of the "1"s right, the terminal will display "PROG". If not, try "Y" + "1" + "1" again, using different pauses. The "1" (pause) "1" is the sensitive part. If you made it this far, the hard part is over.
Enter "Battery Gain Adjust" mode. Now that the UPS is in PROG mode, capital "B" (<Shift+B>) will display a voltage (for the SUA1000XL; apparently, it shows you the Battery Gain Constant for Jacob's UPS). I consider it a reference only and near-useless. I ignore it and use the voltmeter exclusively.

B: Battery voltage gain.
0=maximum gain, FF=minimum gain.
Adjust with the batteries fully charged, and an accurate voltmeter connected. Factory setting was "E9" on my SUA1500, and "E6" gives me the desired 27.30V battery voltage. . . .
I agree that the battery pack must be fully-charged and a good voltmeter attached to perform any changes. Otherwise, you're going to spend a lot of time wondering why the voltage isn't changing the way you think it should.
Keep these Adjust Battery Gain points in mind as you change this:
Pressing 'B' (<Shift+B>) will display a voltage. It also puts the unit in "Battery Gain Adjust" mode (my terminology). It's very easy to have it drop out of this mode!
In this mode, only the upper row '+' and '-' keys apply. If you press any other key, it will drop out of Battery Gain Adjust mode.
Pressing '+' will raise the Battery Gain constant one notch, and lower the float voltage. Pressing '-' will lower the Battery Gain constant one notch, and raise the float voltage.
Each keypress changes the float voltage ~0.10v.
Adjust Battery Gain.
With the terminal displaying your supposed battery voltage (Adjust Battery Gain mode), take note of your voltmeter's reading, then press a '+' (to lower voltage) or '-' (to raise it). All changes are immediate. The terminal should now display a two-character Gain Constant, in the range of 00 to FF, your new Battery Gain Constant. You won't know your old constant, it never showed it to you (for this model, anyway; apparently, it does show you the constant for Jacob's UPS). To determine (and record, if you wish) the old constant that you just changed, press the complementary adjust key ('+' or '-') and your old (previous) constant value will be displayed. You just moved one step away, then one step back.
Watch the voltmeter. Wait for the new voltage to stabilize. This can be anywhere from a few seconds (for my FLAs, <10) to a couple of minutes. The battery voltage will change about one-tenth of a volt. As long as you only press '+' or '-', you can adjust up & down forever. The UPS will remain in Adjust Battery Gain mode.
Chances are, though, that you'll eventually forget to hold down <Shift> to get the '+' key, and it will display "NO" and drop out of Adjust Battery Gain mode. To continue adjusting, re-enter the mode by pressing 'B' again. You'll be picking up where you left off.
End the session using 'R' (<Shift+R>). The terminal will show "BYE". You can close the terminal, disconnect the cable, etc.: you're finished. All changes are persistent.
----------------------- RUNTIME EXTEND -----------------------------
If needed, you can adjust the external battery count easily with a basic terminal emulator. (Such as HyperTerm or PuTTY in windoze) This will increase runtime by multiples of the original. (so if runtime is 20 min, setting external battery count to 1 will make it 40, 2 will be 60, etc.)
Here's how:
1. Hook up a computer to the UPS via a APC "smart" serial cable. If you don't have a serial port on your computer, you can use a USB to serial converter. You must use an APC cable, as the UPS uses a non-standard pinout.
2. Start up a terminal emulator such as HyperTerm or PuTTY (with serial support).
Port settings are: 2400 baud, 8 data bits, 1 stop bit, no parity, flow control is Xon/Xoff. When using HyperTerm, make sure FIFO buffer is NOT set.
3. When connected, you will NOT be greeted by any prompt! Typing in Shift + Y should show the letters SM in the terminal window, this will confirm your connection.
4. Press > to see the current battery pack count. If no battery packs were installed, it should say 0.
Pressing + will add one pack to the count, - will subtract the count by one. If you have multiple packs, press + several times to add them all. When finished, press > again to check the count.
5. When finished, you can simply close the window (or end the connection in HyperTerm).
