5.1.4 Self monitoring
The self-monitoring monitors the following parts of the hardware:
- Micro-wavedevice (VCO)
- Mixers
- Analogic format channel
- Analogic/digital converter
- Micro-processor oscillator
- Code running
When a failure is detected, the relays are permanently actuated and the LEDs flashing shows an error code (see further, title
6.2, p. 5).
The radar is reset after 1 hour.
5.1.5 RF channel
This parameter allows to shift the radar’s frequency. If two units face each other, they must be put on different channels, so
they cannot trigger each other.
6 LED indicator
6.1 IN NORMAL OPERATION
• The red LED shows the state of the relay 2.
• The green LED shows the state of the relay 1.
6.2 WHEN THE SELF-MONITORING DETECTS AN ERROR
The two leds blink quickly (2 or 4 quick flashes followed by a 1 sec break, according to the detected error.
