1) Test the voltage of DC cable. If the voltage of DC cable is zero,
check the connection of DC cable.
2) If the voltage of DC cable is normal as described in §5.1.2,
there is something wrong in the DC input of inverter. Contact
the supplier of inverter.

Description
Troubleshooting
Table 5.1 System test
Please do the function test regularly.
1) Push the button of rapid shutdown controller. The status of light will be off. Check the solar inverter. The DC current will
be cut off and the DC voltage will be lower than 30V in 30 seconds.
2) Rotate the button of rapid shutdown controller. The status of light will be on. The solar will start to work again.
When the PEFS-PLC-CN stops working, the PEFS-PL80P-11 will have a continuous 0.9 V output and the PEFS-PL80P-21
will have a continuous 1.75 V output.
1) Push the button and stop the PEFS-PLC-CN.
2) Separate the DC cable and rapid shutdown controller. Test the voltage of each DC cable.
