10.2.2
DEVICE FULLY SWITCHED OFF:
When the charger is switched off and the batteries are connected, a small residual current flows
through the charger due to the measuring channels and the leakage current of the internal solid
state relay. By optimising the charger, it has been possible to minimise this current, obtaining a
value of less than 150µA (normally lower than the self-discharge current of the batteries used).
In this way, the battery discharge effect caused by the charger can be considered negligible.
10.2.3
DEVICE SWITCHED ON, WITH NO MAINS INPUT:
As soon as there is no mains power, the charger switches to use the batteries as a power source.
This energy will be used to power the charger control and the loads that are connected to its
output. In this situation, the power consumption of the control is less than 5% of the rated power
for EPS-120-5192 and less than 3% for EPS-200-5193 (intended to maintain the functionality of
the charger's state machine, digital outputs, indicator lights and Ethernet communications).
When the battery voltage drops below a set minimum level, the device opens the solid state relay
that connects the output to the battery (to prevent deep discharge and damage to the battery)
and stops it.

CONFIGURATION:
The charger parameters can be configured using an XML configuration file and/or a WEB browser. However,
the parameters can only be modified within the range established for each of them, for safety reasons.

POWER-UP:
The "Power-up" process is defined as the starting of the charger device and the loads connected to its output,
after sending power to its input.
During this process, the output of the device will go from 0Vdc to the minimum value possible in less than 1
second (as long as the batteries and loads are not damaged).
The following defines the behaviour of the device during the Power-up process in different situations:
-If the battery is not connected:
-The charger starts and begins to power the output. If it starts up with loads that generate
current transients, the device will limit its output current to protect itself.
-If, during this process, the power required at the output is higher than the maximum power
that the device can supply, it will regulate the output current and voltage in order to avoid
exceeding the limits of the charger.
-If, after a period of time, normal operating conditions are not reached, the device enters the
overload recovery process (which will be covered below).
- If the battery is connected to the device, it will be connected to the output as fast as possible (via
the solid state relay), to help the rectifier in the starting process.
The rectifier goes into overload when it is kept in current limitation and/or power limitation for an excessive
period of time, but the output is able to reach a sufficient voltage value. If this situation occurs, the device
goes into overload:
-
it disconnects the battery and cuts the output voltage, stopping the rectifier.
It waits for sufficient time before attempting to start. In this way, the load will not have any power
-
remaining and it can start from 0V.
-
The device restarts, carrying out the Power-up sequence again.
-
If the overload situation persists, the device performs a limited number of restart attempts. Once
this number of restarts has been attempted, the device stops the output completely, keeping its
state machine, digital signals, light signals and Ethernet communications functions on.
To restart the device after an overload situation (where the retry limit has been reached) it is necessary to:
-
Disconnect the device completely (AC input and batteries) and wait until the device is completely
shut down. The input voltage is then sent again.
-
