• Redundant safety feature
independent of microprocessor
indicating software may be
faulty
• Too long period of rest after
complete discharge (42 V
cutoff)and before start charge
• Too much frequent cycling
causing module temperature
to stabilize too high
• Too high ambient temperature
• Cell may be imbalanced or
balancing circuit may not be
working
• Too high cell self-discharge in
other cells
1. Correct fault condition.
2. Disconnect and remove
Evolion from operation.
3. Push front face reset button
or send a reset micro
command (ON/OFF button can
also reset the micro).
4. Continue operation without
fault.
5. If fault persists, contact your
local Saft representative.
