Hi to everybody. Some days ago, I bought an UPS by Forza Power Technologies,
model SL-1001. This Forza SL-1001 is line-interactive, has 14,4 A/h charge
and is rated at 1000VA. Before, I had a TrippLite Omni 500 (or something
like that), a simple contact-closure UPS, and I used nut with the simple
genericupsdriver, so I'm new with this type of UPSs.
NUT doesn't list Forza as a supported UPS so I first tried to use
the "marvelous software" inside, the infamous WinPower. As their name
states, only works well in Windows, because in Linux it only recognizes
RS232-based UPS, but this SL-1001 is detected as a HID device.
Google brings me to this mail list and I tested using the megatec_usb driver,
following recomendations from a mail here. The driver works perfectly -
almost. I have some problems with it. I hope you can help me or enlight me
to cure, at least.
* First: the megatec_usb driver takes sooo long to detect the UPS - almost 70
seconds to say "yes, this UPS talks megatec_usb protocol", so I needed
to
raise the maxstartdelay to 80. It's possible to reduce this time?
* Second: variables detected. Look at the listing:
battery.charge: 87.5
^^^^
Nut states battery is at 87,5% but Winpower says 100%. In fact, with nut,
the battery doesn't charge above 95%. Using megatec_ups -DDDDDD gave me
this
voltage ranges: 13,7V-9,7V, and the maximum battery voltage I ever seen is
13,5V. Is WinPower using relaxed values? Is the UPS needing a battery
recalibrate? I just unpacked and connect it...
battery.voltage: 13.20
battery.voltage.nominal: 12.0
driver.name: megatec_usb
driver.parameter.mfr: Forza
^^^^^^
driver.parameter.model: SL-1001
^^^^^^^
driver.parameter.pollinterval: 1
driver.parameter.port: auto
driver.parameter.productid: 5161
^^^^
driver.parameter.vendorid: 0665
^^^^
This values are really forced in the ups.conf file.
driver.version: 2.2.2
driver.version.internal: 1.5.14
input.frequency: 59.9
input.frequency.nominal: 60.0
input.voltage: 114.4
input.voltage.fault: 114.4
input.voltage.maximum: 115.5
input.voltage.minimum: 114.4
input.voltage.nominal: 120.0
output.voltage: 114.6
ups.beeper.status: enabled
ups.delay.shutdown: 0
ups.delay.start: 2
ups.load: 27.0
ups.mfr: Forza
ups.model: SL-1001
ups.serial: unknown
ups.status: OL
ups.temperature: 25.0
ups.type: standby
^^^^^^^
According with this, this UPS is standby type, so it's incorrect (check
http://www.forzaups.com/product_detail.aspx?PrdId=27#technical)
* And the third and last: if I send a upscmd ups-parallax test.battery.start,
the upsd loss communications with the megatec_usb driver, and only restore
communication when the battery test ends. Why?
Thanks in advance.
