Over current in
charge
Measured charge
battery current >
MAX(1.1 x IMR ; 0)
during 1 s
• Regulated charge mode active
(normal mode of operation)
• Transient or continuous
charge current available from
the rectifier output exceeds
maximum allowed charge
current with margin factor
• Voltage between parallel
connected modules too high
• Refer to technical manual
sections for control of
maximum output charge
current control as a function
of IMR_C or IMR factorized
(in function of the module
temperature).
• Every 1 minute the fast charge
mode will be temporarily
active.
1. If Modbus/RS485 is used,
check communication cable
between modules and SMPS
controller is correct.
2. If no Modbus/RS485 is used,
correct the maximum current
output settings of the SMPS.
3. If the total re-charge current
available exceeds 130 A,
regardless of the number of
parallel connected Evolion,
the output current should be
regulated to not operate with
charge regulated mode active.
4. Contact your local Saft
representative for further
details.

Over current in
discharge
Measured discharge
battery current >
MAX(1,1 x IMD ; 0)
during 1 s
• Transient or continuous
discharge current exceeds
maximum allowed discharge
current with margin factor
• Voltage between parallel
connected modules too high
1. Check and re-size as
necessary the number of
Evolion necessary for the
discharge load. Consult with
your local Saft representative
as necessary.
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.

1. Contact your local Saft
representative if it persists.

Charger overvoltage
Battery voltage > 57 V
during 2 s or Reverse
polarity
• Self-test on startup feature
• Too high voltage setting on
charge
• Evolion connected with reverse
polarity to output power and
powered ON with ON/OFF
• Forbidden charge mode is
active.
1. Correct fault condition by
setting output voltage to the
recommended level.
2. Evolion auto resets (must
be in forbidden charge or
regulated charge mode) after
correction of cause and fault
condition.
3. Continue operation without
fault.
4. If fault persists, contact your
local Saft representative.
