Smart Electric Meter Error Codes and Causes

Nowadays, smart meters have been popularized in most places around the world, but when we use the meters, we sometimes encounter various problems, such as the alarm light is always on. What should we do? We have prepared smart meters. A complete list of electric meter error codes, I hope it can help you.

◆Err-01: Control loop error – when the remaining amount is 0 yuan, the meter relay is disconnected, triggering the control switch to cut off power. When there is an abnormality in the switch or the meter and the energy meter can still continue to use electricity, after decreasing by 1kWh, the LCD displays “ERR-01”; after the power is turned off, “ERR-01” disappears, and after continuing to run for 1kWh, the meter LCD displays “ERR-01”. ERR-01″, when the user purchases electricity, the overdraft electricity fee will be automatically deducted and “ERR-01” disappears.

◆Err-02: ESAM error – the security chip ESAM is faulty, and the ESAM or electric energy meter needs to be replaced for repair.

◆Err-03: Internal card initialization error

◆Err-04: The clock battery voltage is low – the battery voltage is low, and the LCD has a battery display symbol. If there is a power outage, the meter time will be lost, and the energy meter needs to be replaced.

◆Err-05: Internal program error

◆Err-06: Memory failure or damage

◆Err-08: Clock failure – time error, need to observe whether there is any problem with the meter time.

◆Err-10: Authentication error – no encryption successful or remote key update failed.

◆Err-11: ESAM verification failed

◆Err-12: Customer number does not match – User card or remote delivery parameters, if the user number is wrong, a prompt will be displayed.

◆Err-13: Wrong number of recharges – When the user card or remote distribution of parameters, the number of power purchases is wrong, a prompt will appear.

◆Err-14: Electricity purchase exceeds hoarding – Set “999999.99” as the maximum value, and the electricity purchase hoarding exceeds (when purchasing electricity, if: remaining amount + current purchase amount > hoarding amount limit, this prompt will appear. )

◆Err-15: The field parameter setting card has expired for this meter – if you insert a field parameter card into a meter multiple times, this prompt will appear the second time or you insert a field parameter setting card first with a larger version number. card, and then insert a card with a smaller version number than the last one, this prompt will appear or the number of on-site parameter cards has been exhausted. )

◆Err-16: Error in modifying the key – ESAM under the official key, inserting the modification under the test key, and key card will cause this error.

◆Err-17: The sealing key is not pressed – the programming key is not pressed during programming

◆Err-18: Card pulled out in advance – when inserting the card, the card was pulled out too fast

◆Err-19: The table number modification card is full (the card has no free table number allocation) – the number of table number cards is full.

◆Err-20: The number of key card modifications is 0 – the number of key modifications is 0 (the number of key card modifications has been exhausted)

◆Err-21: The meter has opened an account (insert the account opening card into the meter that has been opened and transferred) – (For the meter that has been opened and transferred, insert the newly prepared account opening card again.)

◆Err-22: The meter has not opened an account (the user card is inserted into a meter that has not yet opened an account) – (A used electricity purchase card is inserted into a meter that has not opened an account. The two meters must have the same meter number.)

◆Err-23: The card is damaged or the card type is unknown (such as inserting the card backwards, inserting the iron plate, etc.) – inserting the card backwards, inserting the iron plate, etc.

◆Err-24: The meter voltage is too low (operating the IC card at this time may cause the meter to reset or damage the IC card) – the meter voltage is too low, and this prompt will appear when inserting the card.

◆Err-25: The card file format is illegal (including frame header error, frame tail error, and validation error)

◆Err-26: Wrong card type – (If the user type of the user card or field parameter card is inconsistent with the user type of the parameter preset card, this prompt will appear when inserting the user card or field parameter card.)

◆Err-27: New account opening card that has been opened and transferred (there is data in the write-back area of the new account opening card) – New account opening card that has been opened and transferred (the account opening card that has been used is inserted into an unopened account, 2 tables are required The table numbers are consistent.)

◆Err-28: Other errors (wrong card selection file, wrong file reading, wrong file, etc.) – “ERR-28” will appear on account opening cards with wrong meter number, power purchase times other than 1, etc.

◆Err-51: Overload – When the user uses a load greater than 1.2 times the maximum current, the meter wheel displays “Err-51”

◆Err-52: The current is seriously unbalanced – meaningless for single-phase meters

◆Err-53: Overvoltage – the voltage is greater than 1.15 times Un

◆Err-54: Power factor exceeds the limit – the power factor of the user environment is less than 0.2, and the meter wheel displays “Err-54”

◆Err-55: Exceeding active power demand alarm event

◆Err-56: The direction of active electric energy changes (except for two-way metering) – if the incoming and outgoing lines are reversed, ‘Err-56’ will be prompted, and the LCD will flash “”
