BATTERY TEST:
The EPS-120-5192 and EPS-200-5193 chargers have a battery test (for which parameters can be set) in which
the available capacity of the battery is measured. This test is carried out periodically (it can also be set to be
carried out by default every 16 weeks).
During this test, the battery is discharged by the load that is connected to the device output.
The process for performing this test is described in more detail below:
-
First of all, before starting the test, the charger must make sure that:
o
The battery is connected to the output.
There is voltage at the device AC power supply input.
o
The batteries are in floating mode and have been in this mode long enough to ensure that
o
they are fully charged (for which parameters can be set).
o
There is no alarm indicating that the test should not be performed (e.g. rectifier failure).
-
Then, the rectifier is disconnected to guarantee that all the energy requested by the loads is
provided by the batteries alone.
-
At that stage, the battery current measurement is started at any time. By integrating this value
over time, the remaining capacity of the battery (Ah supplied) is obtained.
-
This operating condition is maintained until:
o
The configured minimum capacity (for which parameters can be set) is reached, meaning
that:
o
The maximum time defined for each attempt (for which parameters can be set) is reached,
in which case:
The battery voltage level limit for the test to be considered failed (for which parameters
o
can be set) is reached, in which case:
If the battery test is unsuccessful, a "Battery Failure" alarm will be generated and no further tests will be
performed. The "Battery Failure" alarm is grouped within the "Urgent Failure " digital output.

CHANGING THE BATTERY:
With the EPS-120-5192 and EPS-200-5193 chargers, the battery may need to be changed because an "Urgent
Failure" alarm has been generated, which in turn is caused by the "Battery Failure" alarm. In this situation,
the periodic execution of the battery test is blocked.
For this reason, after the battery is changed, it is necessary to acknowledge the "Battery failure" alarm and
reactivate the periodic running of the test. This can be done in 3 ways:
-
Through the device's web page. This method does not interrupt the power supply to the load.
-
Switching the device off and on completely (after replacing the damaged battery with the new one
and waiting for the device to completely shut down). This method does interrupt the power supply
to the load for a few seconds.
-
Pressing the device's push button. This method does not interrupt the power supply to the load.

Powering Your Challenge
The test is considered passed and is regarded as completed.
The time at which the next test should be performed is calculated.
The test is considered passed and is regarded as completed.
The time at which the next test should be performed is calculated.
This attempt will be deemed to have failed:
•
If all the planned retries have been performed:
o
The current test will be terminated.
o
The test will be deemed to have failed.
The "Battery Failure" alarm will be generated.
o
o
The periodic execution of the battery test will be blocked.
o
The rectifier will be restarted and will enter constant voltage
charging mode.
If all of the scheduled retries have not been performed, a new retry will be
•
started:
The rectifier will be restarted and will enter constant voltage
o
charging mode (quick charge).
o
It will wait for the charging mode to switch to floating mode.
o
It will wait until the device is continuously in float charging mode.
This ensures that the battery is fully charged (for which
parameters can be set).
It will wait until there is no alarm indicating that the test should
o
not be performed (e.g. due to a charger failure)
o
Once all of the above conditions are met, the battery test starts.
