5. LED indicators
The following indicators show the status of the controller:

REL1-REL2 (green) – these LEDs are illuminated whenever the corresponding relay is
activated (the NO contact is closed and the NC contact is open);

SIG (red) – this LED is used to indicate the GSM network signal level;

STA (yellow) – indicates the working state of TCG120 controller and system messages.
The controller states and system messages are shown in Appendix A .
