Annual test– If selected in the Setting Routine, the battery will be tested
annually for 60 minutes each time, and will indicate this in the display. The point
of departure for the test is that the battery should be fully charged. The test cannot
be performed if there has been a power outage <20 hours before testing time. In
this case, the test is moved by 24 hours.
Once the test has been performed, the unit will return to normal mode. If the test
was approved, it will be stored in the clock (RTC) for checking. It will be indicated
as ”last annual test”. The under voltage protection low battery (22,0 V) is active
and will finish the test if necessary and indicate an error message as Battery error
and Annual test error. <Accept> will also be displayed to enable acknowledgment
of the alarm. The test will not be stored in the clock as an approved test. The test
can be interrupted (after 1 minute), by pressing both buttons simultaneously.
Nothing will be stored in the clock.
Battery disconnect function – The battery power is
checked constantly, and the entire battery circuit is checked every 65 minutes. An
error message will be initiated in case of an interruption.
Overload monitoring – This function works in two ways.
During mains power. The entire load is checked. If it exceeds 150 VA or 120 W
per size (e.g. EPS600=600 VA or 480 W) for over 5 seconds, overload will be
displayed and the alarm will sound. To return to normal operations, reduce the
load and press <Accept>.
In case of a load short circuit, the output port fuse shall fail 5 A/FF (breaks at 11
A on 0.4 sec (2530 VA / W). Check that all output ports are working after fixing.
During battery power. If the battery watt value exceeds 158 W per size +150 W
(e.g. EBS 750 = 5x158+158= 940 Watt) for more than 5 seconds, the out voltage
will be reduced until the load is the maximum allowed, or until the out voltage
reaches 150 V, at which point the inverter will be shut down. The alarm
”overload” will sound and remain until the load has been reduced and the
<Accept> button has been pressed.
Note that the value to the right of the <Accept> button is the VA value that
existed just before the alarm was triggered. When the <Accept> button has been
pressed, all the unit’s parameters can be accessed and pressed. Note that if the
overload remains, the AC voltage will be lower than the nominal to enable only
the maximum power the unit can deliver, either VA or W. While ”overload” is on,
the alarm relay ”load” will be on.
