4.9 Module self test during startup
On startup, a self-test is performed anytime the Evolion is awakened from the sleep mode by either,
•
pressing the ON/OFF
•
applying the rectifier output to the power terminals (minimum 36 Vdc)
•
applying a 12 Vdc signal to pin 4 of the RJ45
The functions that are checked on start up include,
•
Charger overvoltage (Alarm 27)
•
Charger reverse polarity (Safe mode and Alarm 27 & 47)
•
Mosfets or Fuse Blown (Safe mode and Alarm 47), tested if no charger is present
•
Safety redundant channel (Safe mode and Alarm 47)
•
Current not in the deadzone (Safe mode and Alarm 47)
•
Software and Parameters CRC invalid (Safe mode and Alarm 47)
•
Memory check invalid (Safe mode and Alarm 47)
The duration of the self-test takes less than 3 seconds. Each parallel module in an Evolion battery bank may not start and finish the
self-test at the same time. In that case, a “soft start” or “ramp in” feature on the rectifier output is useful. This feature helps to prevent
one Evolion (the first to complete its self test) from bearing all the output charge current.The battery will not operate until the self-test
is complete.
During discharge mode, the following function is self-tested.
•
Heater (Alarm 44)
During float charge mode, the following function is self-tested.
•
Fuse (Alarm 29)
During normal or safe mode operation, the following functions are self-tested.
•
Safety redundant channel (Safe mode and alarm 47)
•
Software and Parameters CRC invalid (Safe mode and Alarm 47)
•
Memory check invalid (Safe mode Alarm 47)
