As I explained in another reply in this thread, my NUT version is
OK, it is 2.4.1.

I tested the shutdown both by forcing it ('upsmon -c fsd') and also
by turning off the AC power. It works OK.

But I noticed one big problem during coldstart. As soon as the
megatech driver is loaded, UPS just turns off the load. Of course
the syslogs are corrupted, so cannot understand what is happening.


As you recommended below, I will test the blazer_ser driver.

I switch to the blazer_driver

[Numeric]
        driver = blazer_ser
        port = /dev/upslink
        desc = "Numeric 2000 LI"
        default.battery.voltage.high = 41.0
        default.battery.voltage.low = 30.4
        default.battery.lowbatt = 25



# upsc Numeric
battery.charge: 100
battery.lowbatt: 25
battery.voltage: 41.00
battery.voltage.high: 41.0
battery.voltage.low: 30.4
battery.voltage.nominal: 36.0
beeper.status: enabled
driver.name: blazer_ser
driver.parameter.pollinterval: 2
driver.parameter.port: /dev/upslink

input.current.nominal: 8.7
input.frequency: 49.5
input.frequency.nominal: 50
input.voltage: 225.1
input.voltage.fault: 225.1
input.voltage.nominal: 230
output.voltage: 224.0
ups.delay.shutdown: 30
ups.delay.start: 180
ups.firmware: VER 40643N

ups.type: offline / line interactive


This does not have the coldstart problem. >>Big Relief<<
Shutdowns are also OK.

Next I tried to setup the 'runtime' calculation. As the batteries in the
UPS are old (I think they need to be replaced), I do not want to
use the rated runtime. I have two data points now,
at 12% load, the runtime is about 10 minutes and at 70% load it
is two minutes.

So added the following line to upsc.conf

        runtimecal = 60,72,600,12


But now, both battery.charge and battery.runtime are wrong.

tej nut-monitor-1.1 # upsc Numeric
battery.charge: nan    <===============
battery.lowbatt: 25
battery.runtime: 0
battery.voltage: 40.80
battery.voltage.high: 41.0
battery.voltage.low: 30.4
battery.voltage.nominal: 36.0
beeper.status: enabled
driver.name: blazer_ser
driver.parameter.pollinterval: 2
driver.parameter.port: /dev/upslink
driver.parameter.runtimecal: 60,72,600,12
driver.version: 2.4.1
driver.version.internal: 1.51
input.current.nominal: 8.7
input.frequency: 49.5
input.frequency.nominal: 50
input.voltage: 225.1
input.voltage.fault: 225.1
input.voltage.nominal: 230
output.voltage: 224.0
ups.delay.shutdown: 30
ups.delay.start: 180
ups.firmware: VER 40643N
ups.load: 14
ups.mfg: NUMERIC
ups.model: 2000 Plus
ups.status: OL
ups.temperature: 46.0
ups.type: offline / line interactive


Any hints as to what could be wrong ?

Thanks !
