3noF – when the value of the measured quantity at any phase is lower than the "Lower
value of condition” - the condition is met. The condition is disabled when the value of
the measured quantity at all phases is higher than the "Upper value of condition."
3_on – when the value of the measured quantity at any phase will be between
"The lower value of condition," and "Upper value of condition" - the condition is met.
The condition will be disabled if the value of the measured quantity is below the "Lower
value of condition" or above the "Upper value of the condition” at all phases.
3_oF – when the value of the measured quantity will be below the "Lower value of
condition" or above the "Upper value of condition” at any phase - the condition is met.
The condition will be disabled if the value of the measured quantity is between the
"Lower value of condition" and the "Upper value of the condition” at all phases.
In the 3rd series of alarms the alarm value must come from the following ranges: 01-09,
10-18 i 19-27 (acc. to table 8). They work with the same Hysteresis thresholds of the
"Lower values of condition" and "Upper value of condition" for each phase. Alarms
signaling maintaining is switched off after pressing
