Do I need to repair the counter if the indicators are off?
At the cottage, the specialist sealed the Neva 303 counter with subsequent connection to the network. As a result, I concluded that the meter is malfunctioning, since the indicator lights on it do not light (there is an output voltage). There is no load at all, because there is no output to the house yet. Says - repair. Is he right?
Loading...
There are three indicators on this counter - voltage indicators for each of the phases A, B, C. If there is a voltage at the output, but they do not light up, then the meter is faulty - they all told you correctly. The load is indicated by the fourth LED on the right - it flashes with a frequency depending on the magnitude of the load.
2.13 The meter has an LED indicator of functioning, to which light pulses are issued, proportional to the amount of energy consumed.
Counter constant (number of pulses corresponding to one kilowatt hour)
it is applied on a guard next to the LED indicator.
CE-303 meters have indicators of the functioning of the measuring elements of each
out of phases. The indicators flash at a rate proportional to power consumption,
but significantly higher than the flashing frequency of the operation indicator
counter. Visually, blinking is discernible only at low power consumption,
at a load power of 2% of the maximum and above, the indicators light constantly.
Counters NEVA 301 have indicators of the presence of phase voltages. On the left of
indicators on the shield marked "U". In the presence of phase voltage
LEDs light up. In the absence of one of the phase voltages, the LED
the corresponding phase will not light.
indeed, apparently I found another instruction. Error. Then they should not burn or blink. Bred to install a new counter
Your electrician is a kettle. phase indicators are lit not from the presence of phases, but from the presence of a load.
The same counter, used for nine years, and glucan. From 30,658 kilowatts, he immediately threw it to 32968. (he took his first testimony on August 17 of this year, the second testimony on September 20). Wound up 2310 sq.h. (more than 9t.r.) And now what to do? How to be? Of course I’ll go write an application for an examination of the device’s performance, and change it to a liquid crystal display. Who will advise what? Thank.
What LCD that mechanics is one and the same. Brains are the same
