• 2 Red LEDs give
LED SIGNAL
• the corresponding loop detection state in normal situation
• the value of the oscillation frequency measurement or an error message on power ON
In normal situation the red LED stays ON as long as the loop detects any metallic object.
On power ON the sensor measures the oscillation frequency of each loop. The result of this measurement is
displayed using the corresponding red LED. The amount of blinking indicates the tens value of the frequency.
For example 4 short flashes correspond to a frequency between 40 kHz and 49 kHz. After this message the
LED goes back to normal display. If the loop oscillation frequency falls outside the limits set between 20 kHz
and 130 kHz the red LED displays an error message and the sensor activates the corresponding relay. The
blinking frequency shows the type of error according to the next table. The sensor will stay in this state until
the problem is cleared and the frequency goes to the right range.
Remark : The sensor launches automatically a learning process if the oscillation frequency changes more than
10% in comparison with the measurement value.
