If the electronic switch opens due to a major alarm, in most cases the major alarm will reset automatically, after the fault condition is
corrected, and the electronic switch will in turn close to continue normal operation. If the 60 Amp replaceable fuse ever opens, it must
be replaced in order to make the Evolion operable. See Evolion installation and operation instruction for details.
Important note: If the redundant 75 Amp fuse ever opens (tertiary protection), the unit must be replaced.
Important note: If an Evolion module is exposed to 130 Amps or more of discharge load or re-charge current, even for a short time, the
mosfets on the BMST power board may be damaged if the 60 Amp replaceable fuse doesn’t act. In that case the module must be replaced.
4.8 Safety limits during operation
Each Evolion measures and controls its own state. It operates independently regardless of the number of modules that are connected
in parallel and without the need of an external master BMS. Safety limits are defined and are controlled based on the measured state
of the module or cell.
There are two types of alarms.
Type LED indication Operation mode when active
Major alarm steady Safe mode (stops module operation)
Warning alarm
steady
Nominal mode (continues module operation)
When either alarm occurs, the LED’s indicate which. Additionally, a dry contact signal can be actuated (pins 7 and 8 on the RJ45) anytime a
major or warning alarm is activated. The alarm outputs are set by the user and are configurable using the Evolion Toolbox software.
Additionally, the alarm signal is communicated on the RS485 transmission bus. The Modbus communication protocol can be used to
communicate the alarm states to the application. See more details in the Evolion communication user manual.
Most major and warning alarms will automatically reset when the limit value is no longer exceeded (hysteresis included). In some
cases, the alarm will not reset or can only be reset by either cycling ON and OFF the charger/rectifier output or providing a BMST reset.
A summary of the main operational safety limits are given in the Figure 5.
