Normal operation mode.
The duration of the awake state is 2 minutes. The voltage converter powering the sensor is started. The sensor value is taken and the battery voltage is measured.
If the ALARM is not present, the button can enter the test mode, in which the LEDs flash in the manner 1 and the relay is activated.
To exit the test mode, press the button again. In the test mode, we do not check the sensor satus. Each press of the button extends the normal operating time to 2 minutes.
If it is found that the battery is discharged, the relay is turned on and the LEDs flash in the manner 1.
If a short-circuit alarm is detected, the relay is turned on and the LEDs flash in the manner 2.
If an open-circuit alarm is detected, the relay is turned on and the LEDs flash in the manner 2.
If an alarm is detected, the relay is turned on and the LEDs flash in the manner 3.
If the alarms stop, the relay is disconnected and the LEDs do not flash. After 2 minutes, the device goes into sleep mode.
In alarm states, the LEDs flash until the next measurement of the state of the probes (1h), i.e. until the device is woken up.
After 2 minutes, the system goes into sleep mode.
Duration of the Sleep Mode is 60 minutes. In this mode, the current consumption is negligible and amounts few microampers, the LEDs will blink a single flash every 20 seconds to inform you of the system’s operation.
If the button is pressed for up to 5 seconds, it will wake up the system and switch to the normal operation mode.
