– Each anomaly has an independent delay time. The anomaly must last uninterruptedly more than the time specified to invalidate the voltage presence signal.
– When all the line parameters are restored within the specified limits, before the line may be used, the line presence delay time must elapse. The duration of
this time is specified by two independent parameters, one defining the delay time when the alternate line is available, and a second one, normally shorter, that
defines the delay in case of the alternate line is not available.
– All controls, except minimum voltage, may be excluded independently, by setting the relevant parameters to OFF.
– The limits of minimum and maximum voltage are specified by setting two thresholds each, one defining the point beyond which voltage is considered no
longer acceptable (e.g. P3.01, drop-out) and the other, closer to the rated voltage, defining the point when it is compatible again (e.g. P3.02, pick-up). The
distance between these two thresholds defines hysteresis. For instance, it can be stated that below 80% of the rated value, voltage can no longer be used and
that, it must rise above 85%, to be deemed satisfactory, thus defining a 5% hysteresis (dead-band). The same principle is applied to maximum voltage.
– At power up or resetting of the device, each line is considered all satisfactory when voltage is within pickup limits, unless the relative circuit breaker is
already closed.
– As concerns frequency thresholds, there is a fixed hysteresis equal to 1% of rated frequency.
– For phase loss, the pick-up threshold is the same one for minimum voltage.

PARAMETERS SET-UP

– With the unit in OFF-RESET mode, press the H and A keys together for five consecutive seconds.
– The LINE 1 display will show the code of the first parameter. The first digit of the code is the menu number which flashes alternating with a P, while the two
following digits indicate the number of the parameter within the menu. The first parameter is P1.01, i.e. menu P1,
parameter 01.
– Press keys A and C to scroll the parameters of the same menu.
– Press keys E and F to browse the different menus.
– The digit identifying the parameter is shown on LINE 1 display, while the current setting is shown on LINE 2 display.
– Press keys B and D to change the setting of the selected parameter.
– By moving to another parameter or quitting the menu, the setting will be stored automatically.
– Press key H to quit parameters set-up.
– If no keys are pressed for more than
2 minutes, the unit exits set-up automatically without storing the changes.

P1.01 - Rated voltage used for threshold calculation; thresholds are expressed as Ue percentage. In case of two or three-phase systems, set the phase-to-phase
voltage.
P1.03 - Defines the system wiring configuration used. The setting between
3-phase and 3-phase + neutral influences the viewing only.
P1.04 - Specifies if the voltage controls are applied to L-L voltages, to L-N voltages or to both voltages.
P1.05 - Rated frequency used as reference for frequency threshold calculation.
P1.06 - Used for alarms on battery voltage.
