A cell is going under
voltage
Cell voltage < 2,55 V
during 2 s
• Too long period of rest after
complete discharge (42 V
cutoff) and before start charge
• ON/OFF button left ON in long
storage
• Too high cell self-discharge
• Too high cell dispersion at end
of complete discharge
• Refer to alarm 60
• At 2.5 V, IMD_C will be zero
and as a result the electronic
switch will open in safe mode.
• Refer to alarm 24
• At 3.0 V, the module will go into
sleep mode automatically after
1 hour.
1. This alarm is active normally
in storage or when not
connected in operation or at
the end of discharge.
2. Begin refreshing charge
procedure immediately
3. Evolion auto resets after
correction of cause and fault
condition.
4. Continue operation without
fault.
5. If fault persists, contact your
local Saft representative.

A cell is under
voltage
Cell voltage < 2,15 V
during 2 s
• Redundant safety feature in
microprocessor
• Refer to alarm 12
1. This alarm is active normally
in storage or when not
connected in operation.
2. Begin refreshing charge
procedure immediately
3. Reset the module.
a. For single connected module,
turn output power from
rectifier OFF and then ON and
after the fault should reset.
b. For parallel connected
modules, BMST reset or
Evolion OFF/ON is necessary
4. Continue operation without
fault.
5. If fault persists, contact your
local Saft representative.

damaged
• Refer to alarm 10, 11, 12 and
13
• Refer to alarm 1
1. Contact your local Saft
representative if it persists.

• Sensor failure short circuit or
open
• BMST busbar board may be
damaged
• Refer to alarm 6, 7, 8 or 9
• Refer to alarm 1
1. Contact your local Saft
representative if it persists.
