Operating principle
In a 3-phase network, the FW simultaneously monitors phase sequencing, loss of phase with a
maximum regeneration rate of 70 % of the voltage displayed by a potentiometer on the front face,
and symmetrical voltage drop on the 3 phases of less than 20 % of the preset value.
When the 3 phases succeed on another, the output relay is activated and indicated via a yellow
LED.
The output relay de-energises (LED off) after a time delay T, adjustable between 0.2 and 10
seconds on the front face, if one of the following faults is present :
- reversed direction of phase rotation,
- absence of one or more phases,
- volgage drop.
Note :
Time delay T is not operational during loss of L1 and L2.
It operates during loss of L3, phase inversion or voltage drop. Its role is to prevent spurious
triggering of output relays during transient states, notably during motor starting.
