GREEN LED shows when the module is powered.
RED LED gives:
• The corresponding loop detection state in normal situation;
• The value of the oscillation frequency measurement or an error message on power ON.
Normally, the RED LED stays ON as long as the loop is in a state of detection.
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 number of flashes 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 (20 kHz to 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 error mode until the error is cleared and the
frequency goes to the right range.
Remark: The sensor launches automatically a learning process if the oscillation frequency varies more than 10% in comparison with the
measurement value.
LOOP FREQUENCY ERROR LED DISPLAY
Oscillation frequency too LOW or loop opened LED blinking at 1Hz
Oscillation frequency too HIGH LED blinking faster at 2 Hz
Loop shorted or no oscillation LED blinking slower at 0.5 Hz
