Fuse blown
Voltage between
cells and network
is different by ± 2 V
during more than 10
minutes.
• Charge or discharge current
exceeded the maximum
time = f(current) curve for
replaceable fuse.
• Evolion connected to output of
rectifier and turned ON when
AC power is OFF.
• Voltage between parallel
connected modules too high
1. Disconnect Evolion and turn
OFF.
2. Check replaceable fuse
(replace if necessary).
3. Turn ON Evolion. The alarm is
auto reset after the good fuse
is detected in place.
4. Connect and continue
operation without fault.
5. If fault persists, contact your
local Saft representative.

Low SOC – 1st level
SOCmin ≤ 20 %
during 3 s
• The SOC of the Evolion is
below 20 % in storage or in
normal operation.
• Long storage without
refreshing charge.
• Long discharge consuming
80 % of the full charged
capacity.
• Too short time re-charge after
a full discharge.
1. Re-charge above 20 %.
2. Evolion auto resets after
correction (5 % hysteresis) of
cause and fault condition.
3. Continue operation without
fault.
4. If fault persists, contact your
local Saft representative.

Low SOC – 2nd level
SOCmin ≤ 10 %
during 3 s
• The SOC of the Evolion is
below 10 % in storage or in
normal operation.
• Long storage without
refreshing charge.
• Long discharge consuming
90 % of the full charged
capacity.
• Too short time re-charge after
a full discharge.
1. Re-charge above 10 %.
2. Evolion auto resets after
correction (5 % hysteresis) of
cause and fault condition.
3. Continue operation without
fault.
4. If fault persists, contact your
local Saft representative.

Battery voltage above
limit
Battery voltage > 57 V
during 2 s
• Forbidden charge mode active
• Too high voltage setting on
charge
1. Correct fault condition
setting output voltage at
recommended level.
2. Evolion auto resets after
correction (must be in
discharge mode to decrease
cell voltage) of cause and fault
condition.
3. Continue operation without
fault.
4. If fault persists, contact your
local Saft representative.

25
Battery voltage below
limit
Battery voltage < 42 V
during 2 s
• Low voltage disconnect in
normal operation for complete
discharge
1. Begin re-charge within 14
days of reaching this limit.
2. 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
3. Continue operation without
fault.
4. If fault persists, contact your
local Saft representative.
