4.5 Start the PVRSS system
Turn on the power source of rapid shutdown controller. The rapid shutdown control system will start to work.
The status of lights is shown as below:

| On| Off
---|---|---
Power (Red)| Rapid shutdown controller is powered on and send signals to the
rapid shutdown devices in each string.| Rapid shutdown controller is powered off or stop sending signals to the rapid shutdown devices in each string.

Table 4.1 Light Status

Firefighters can push the button to cut off all the solar modules while in the emergency.
After the emergency, users can rotate the button and the solar module will work again.

System Test and Troubleshooting

5.1 System test
5.1.1 Function test
Please do the function test regularly.

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.
Rotate the button of rapid shutdown controller. The status of light will be on. The solar will start to work again.

5.1.2 Maintain test
When the TSOL-RSDM-CQ stops working, the TSOL-RSDM-DS will have a continuous 0.9 V output and the TSOL-RSDM-DD will have a continuous 1.75 V output.

Push the button and stop the TSOL-RSDM-CQ.
Separate the DC cable and rapid shutdown controller. Test the voltage of each DC cable.

System Voltage = 0.9 V Quantities of TSOL-RSDM-DS or
System Voltage = 1.75 V Quantities of TSOL-RSDM-DD| System Work
Normally
---|---
System Voltage < 0.9 V Quantities of TSOL-RSDM-DS or
System Voltage < 1.75 V Quantities of TSOL-RSDM-DD| System Work

5.2 Troubleshooting

Description	Troubleshooting
Status light is always off. PVRSS doesn’t work.	1) Check if the button of

controller is turned to off;
2) Check if the AC power supply is normal;
3) Check if the AC voltage is over the operating voltage rang;
4) Contact TSUN.
Status light is on.
DC voltage of inverter is 0V.
PVRSS doesn’t work.| 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.
3) Contact TSUN.
Status light is on. DC voltage of inverter is normal.
PVRSS doesn’t work.| 1) Replace a new rapid shutdown controller.
2) Contact TSUN.
Status light is on. PVRSS work well.
DC voltage of inverter is abnormal (§5.1.2).| 1) Test the output voltage of each rapid shutdown device. If the output voltage is not 0.9V or 1.8V. Replace the rapid shutdown device.
2) Contact TSUN.
