Thresholds for current sensor discharge detection
The direction of current flow indicates whether the batteries are charging or discharging. In principle, you need to differ between three
charging or discharging states:
1. Discharging
The batteries discharge while granting emergency power.
2. Charging
If batteries drop below a certain voltage level, they must be charged. This battery state can be reached via a natural discharge
process over time or in case of emergency power usage. The charging process is always initiated and terminated by the UPS
/ Charger. By "Equalizing", BACS distributes the existing charging current and voltages - Each battery charge is considered
individually to ensure the optimal charging.
3. Trickle charging
Batteries tend to self-discharge over time. This process can not be prevented, but slowed down by proper storage. The trickle
charge hereby serves to maintain the current state of charge. Normally, a trickle charging will not be displayed.
Depending on the charging behavior of a UPS, certain currents always flow within a system. Due to this fact, it cannot generally be
assumed that a current flow is automatically a charge / discharge cycle. Since only two of the possible states are important for the
current sensor to detect a charge or discharge cycle, it is necessary to define a fixed point at the current intensity for a charge/discharge
cicle.
With the "Thresholds", the values can be adapted to the environment that a clear charge or discharge cycle can be assumed.
The negative sign defines the discharge cicle and the positive sign the charge cicle.
How to configure the BACS modules
Addressing BACS modules: The BACS programmer
The BACS modules can be configured by using the WINDOWS program BACS PROGRAMMER or via the web interface in the CS141 /
BACS WEBMANAGER.
To use the BACS programmer in the web interface, navigate to the following menu:
To install, configure, or remove new BACS modules, the BACS system must be put into standby for this time window. First set the
Programmer Input Capability to "On":
