Charge status bar. Gives a rough indication of the charging progress, see below :
LED 3a : 100% full (ready)
LED 3b : 80% full
LED 3c : 50% full
LED 3d : empty

4.2.1. Error indications
When the so called mode indicator LEDs are blinking red, an error has been detected. Each
mode indicator LED can either blink red individually, or combined along with one or more
other mode indicator LEDs. There are five different error indications, each with their own
blinking pattern :
One flash in a row : Battery related error (too low or too high battery voltage, too
low or too high battery temperature, too high battery ripple
voltage, battery defect)
Two flashes in a row : AC overload error (AC load requires too much power from the
inverter, AC output short circuit)
Three flashes in a row : High temperature error (Powersine Combi shuts down on high
temperature)
Four flashes in a row : Device error (an error has occurred inside the Powersine
Combi. Please return for service)
Five flashes in a row : Charge program error (only for ‘charger on’ indicator LED).
Charge program selection set to Custom, while custom made
charge program contains an error or time-out.
The Powersine Combi will mostly recover from an error mode automatically when the cause
of the error has been resolved. However, when an error has occurred due to a high battery
ripple voltage or an AC transfer switch overcurrent, a manual reset of the Powersine Combi
will be necessary. The Powersine Combi also needs to be reset manually, when too many
battery or overload errors have occurred within a short period of time.
4.3 Alarm relay
The Powersine Combi is equipped with a potential free alarm relay. Standard, this relay will
be activated when the unit shuts down and jumps to an error mode. The alarm relay de-
activates again when the error has been resolved and the Powersine Combi is running
in normal operating mode again.
Using TBS Dashboard, it is also possible to configure the alarm relay to perform a different
task, like starting a generator when the battery voltage has reached a certain low voltage
level (not available yet in firmware version 1.0.x).
