4)Monitor Battery Calibration progress

5)Program EEPROM

6)Enter TTY mode communicating with UPS

7)Quit

Select function number:

You might want to run option 1) just to ensure that apctest is properly talking to your UPS. It will produce quite about 70 lines of output.

To program the EEPROM, select option 5), and you will get the EEPROM menu as follows:

This is the EEPROM programming section of apctest.

Please select the function you want to perform.

1)Print EEPROM values

2)Change Battery date

3)Change UPS name

4)Change sensitivity

5)Change alarm delay

6)Change low battery warning delay

7)Change wakeup delay

8)Change shutdown delay

9)Change low transfer voltage

10)Change high transfer voltage

11)Change battery return threshold percent

12)Change output voltage when on batteries

13)Change the self test interval

14)Set EEPROM with conf file values

15)Quit

Select function number:

If you wish to use the old pre-3.10.x method of EEPROM programming with values specified in the apcupsd.conf file, select option 14). However, we recommend that you start with item 1) to see what EEPROM values apctest finds. This command can take a few minutes to run, so be patient. The values printed should be the same as what you got using apcaccess, but in addition, the EEPROM battery date and UPS Name should be displayed. For example:

UPS control system specifications

APC UPS (Uninterruptible Power Supply) control systems are vital components for ensuring uninterrupted power supply and protecting critical equipment from power interruptions, surges, or fluctuations. Designed by Schneider Electric, APC UPS systems are renowned for their high quality and reliability. They utilize advanced technologies and features to suit diverse applications, from home offices to large industrial settings.

One of the main features of APC UPS systems is the ability to provide backup power during outages. This is achieved through a battery system that activates immediately when the mains power fails. This seamless transition minimizes downtime and ensures that electronic devices continue to operate, protecting data integrity and equipment lifespan.

Another significant characteristic of APC UPS systems is their intelligent management capabilities. Most models come with PowerChute software, which provides users with real-time monitoring of power conditions and the status of the UPS. This software allows for graceful shutdowns of connected devices during extended outages, thereby preventing data loss and damage to devices.

APC UPS systems also incorporate advanced technologies such as Automatic Voltage Regulation (AVR). AVR technology ensures that the output voltage remains stable by correcting minor fluctuations without switching to battery mode. This not only prolongs the battery life but also provides a consistent power supply to the connected equipment.

Thermal management is another critical aspect of APC UPS control systems. The design often includes efficient cooling systems that prevent overheating, ensuring optimal performance and longevity of the unit. Some models feature EcoMode, which reduces energy consumption and lowers operational costs by working at high efficiency only when battery backup is not required.

APC UPS systems are designed with scalability in mind. Users can easily add more batteries or connect additional UPS units to accommodate growing power needs. Features such as hot-swappable batteries and modular design facilitate easy upgrades and servicing without interrupting power supply.

In terms of connectivity, APC UPS products often feature multiple options including USB, RS-232, and network management capabilities. This enables users to connect remote management tools and integrate the UPS with existing IT infrastructure.

In summary, APC UPS control systems deliver reliability, efficiency, and advanced technology features that cater to a wide array of power protection needs, making them a trusted choice for individuals and businesses alike.
