Indicator |
Status |
Meaning |
|
---|---|---|---|
Power indicator |
Steady green |
The PID module is powered on. |
|
Green off |
The PID module is powered off. |
||
Run indicator |
Steady green |
The PID module works in normal mode and Running status is Starting or Running. |
|
Blinking green at short intervals (on for 0.5s and then off for 0.5s) |
The PID module works in commissioning mode and Running status is Commission: running. |
||
Green off |
Running status is not Starting, Running or Commission: running. |
||
Communication
indicator |
Blinking green at short intervals (on for 0.5s and then off for 0.5s) |
The PID module is receiving data over RS485. |
|
Green off |
The PID module has not received data over RS485 for 10 seconds. |
||
Fault/Maintenance
indicator |
Fault state |
Steady red |
The PID module is faulty. |
Local maintenance state |
Blinking green at long intervals (on for 1s and then off for 1s) |
Local maintenance is in progress. |
|
Blinking green at short intervals (on for 0.125s and then off for 0.125s) |
Local maintenance fails. |
||
Green steady on |
Local maintenance succeeds. |
||
Green off |
The PID module is not under maintenance. |
- Local maintenance refers to operations performed after a USB flash drive, Bluetooth module, or USB data cable is inserted into the USB port of the PID module. For example, local maintenance includes data import and export using a USB flash drive and connecting to the SUN2000 app over a Bluetooth module or USB data cable.
- If a fault occurs during maintenance, the alarm/maintenance indicator shows the maintenance state first. After the USB flash drive, Bluetooth module, or USB data cable is removed, the indicator shows the fault state.
