provides an uninterruptible power supply for loads operating at sinusoidal AC, generated

from direct current power sources.

The inverter module provides galvanic isolation between the output and the battery. The

presence of galvanic isolation guarantees the highest protection level for the load from

external impacts.

Each inverter module has an indicator that digitally displays the following values listed

below:

Indication regimes Error codes

Output current to the loads AAC 002 Low battery voltage

Output voltage VAC 008 Short circuit

Battery voltage VDC 016 Low output voltage

Routine information ----- 020 Overload

032 Unsynchronization

048 No input voltage

The different available display indication regimes can be switched by pressing the „MODE”

button (Fig. 2.12, marked with red circle). The mode`s corresponding LED lights up.

8. Charging system

The charge controllers are with compact dimensions, a height of 1U, and with exceptionally

high power density coefficient per unit volume. The easy operation, the suitability for fast

scheduled maintenance and excellent maintainability in combination with their high

reliability are a guarantee for saving time, costs, resources and extremely valuable time.

Each charge controller has a highly reliable fail-safe structure and is constructed based on

multiple fault-tolerant solutions. Hot Plug and Hot Swap technology is integrated.

Each controller can be started after it is carefully slid in its slot (the plates must be out

during sliding in) and the two connecting plates located on both sides of the front panel are

pushed in. The left plate on each charge controller is an electronic switch.

Auto diagnostics procedure will follow immediately after the charge controller has been

started. After the necessary start-up tests are finished the first two LED diodes on the front

panel will light up.

SETTINGS button for longer than 5 seconds, until the main menu shows back on the

LCD display.

If the MCU behaves unexpectedly, restart the MCU by plugging it out and back in, or by turning off the complete DC power system by switching the circuit breakers to off.

After entering a submenu the only way to go back to the main menu is to complete the started settings cycle explained.

10. How does the charging mode work

10.1 Automatic mode In an automatic mode the system determines the battery charging mode by itself.

This depends only on the pre-set parameters by you. The criteria for switching from Float to Boost is the battery`s charging current limit (Ibsw F2B) which you can pre-set through Menu №11. If this limit is crossed, the system will automatically switch to Boost mode. The criteria for switching from Boost to Float is the battery`s charging current limit (Ibsw F2B) which you can pre-set through Menu №11. If the system crosses this limit, additional timer (ADD TIMER) will be turned on. Its aim is to ensure full charge of the battery while the system keeps being in Boost mode simultaneously. A timer that counts the amount of time for which the system has been in Boost mode has been added (TMR BST MAX). Its aim is to prevent a long stay of the battery under high charging voltage. When one of the timers runs out, the system will automatically switch back to Float regime.

10.2 Manual mode

In manual mode, you have to choose the battery’s charging mode by yourself. The first option is Float mode.

In this regime the battery charging current limit will be the decisive point for switching between Float and Boost.

Another option is Boost mode. In this mode the battery charging current limit will be the maximum charging battery current (Ibch Max) that has been pre-set. However for safety reasons a timer will be automatically started here as well (TMR BST MAX). Its purpose is to count the time in a Boost mode. After it runs out the system will automatically switch back to Float mode.
