L1 - 04 IGBT error (Master: Inverter
PCB)
The inverter PCB may be faulty
or a PCB other than the specified
one is mounted. Refer to the “L1”
flow chart of each manual and
make a diagnosis of the relevant
unit based on the Error code
shown to the left.
L1 - 07 Instantaneous overcurrent
(Slave 1: Inverter PCB)
The inverter PCB may be faulty.
Refer to the “L1” flow chart of
each manual and make a
diagnosis of the relevant unit
based on the Error code shown
to the left.
L1 - 08 Current sensor error (Slave
1: Inverter PCB)
L1 - 09 Current offset error (Slave 1:
Inverter PCB)
L1 - 10 IGBT error (Slave 1: Inverter
PCB)
The inverter PCB may be faulty
or a PCB other than the specified
one is mounted.
Refer to the “L1” flow chart of
each manual and make a
diagnosis of the relevant unit
based on the Error code shown
to the left.
L1 - 12 Instantaneous overcurrent
(Slave 2: Inverter PCB)
The inverter PCB may be faulty.
Refer to the “L1” flow chart of
each manual and make a
diagnosis of the relevant unit
based on the Error code shown
to the left.
L1 - 13 Current sensor error (Slave
2: Inverter PCB)
L1 - 14 Current offset error (Slave 2:
Inverter PCB)
L1 - 15 IGBT error (Slave 2: Inverter
PCB)
The inverter PCB may be faulty
or a PCB other than the specified
one is mounted.
Refer to the “L1” flow chart of
each manual and make a
diagnosis of the relevant unit
based on the Error code shown
to the left.
L4 - 01 Radiation fin temperature
rise (Master: Inverter PCB)
Refer to the “L4” flow chart of
each manual and make a
diagnosis of the relevant unit
based on the Error code shown
to the left.
L4 - 02 Radiation fin temperature
rise (Slave 1: Inverter PCB)
L4 - 03 Radiation fin temperature
rise (Slave 2: Inverter PCB)
L5 - 03 Current offset error (Master) Refer to the “L5” flow chart of each
manual and make a diagnosis of
the relevant unit based on the
Error code shown to the left.
