6.3.13 CAN O-T
Meaning: CAN communication over time
Reason: CAN slave detect the communication interrupt timeout
Solution: 1. CAN communication wire is not reliable,exclusion it;
2. CAN network must have an 120
Ω
anti reflection resistance, every device has an
120
Ω
resistance, but the entire network can only have one device short connect to
this resistance,proposed short connect with the farest one from master.
3. The interference too much, CAN communication wire was recommended to use a
dual core shielded wire connection, shielding layer grounding, the worst also want to
use a twisted pair connection.
6.3.14 H-W LCK
Meaning: Hardware lock up
Reason: Drive circuit fault
Solution: Interior fault
6.3.15 OutLine
Meaning: Outline with eletric
Reason: The output wire is connected to the power supply.
Solution: 1. The output wire was connected to the device with AC power output,remove it.
2. The failure is only produced by the power of the detection, once the output is normal
will no longer be detected, can not be expected to be used to protect when the device
is working.
6.3.16 CHGR -C
Meaning: Solar charging over-current-1
Reason: Solar charging,battery current over current
Solution: PV panel configuration too large, reduce the configuration
6.3.17 PV -OC
Meaning: Solar charging over-current-2
Reason: Solar charging,PV panel current over current
Solution: PV panel configuration too large, reduce the configuration
6.3.18 PV -OV
Meaning: Solar panel over voltage
Reason: Solar panel voltage over voltage
Solution: Series PV panel too much, reduce it
6.3.19 BT Full
Meaning: Battery full charging
Reason: The battery is full, the fault is only a notice, will automatically reset
Solution:
6.3.20 Unknow
Meaning: Unknow
Reason: Extension,not defined
Solution:
