P08.21 - P08.22
- These define the ON and OFF time of the pulse controls for increasing or decreasing the voltage or frequency, respectively. These times influence
the programmed outputs with the increase voltage, decrease voltage, increase frequency and decrease frequency functions. The signals are intended to
be sent to a genset control unit with the purpose of reaching synchronisation conditions.

Note: This menu is divided into 3 sections for Source Line Controls SLC1..3.
P09.n.01, P09.n.02, P09.n.03
- The first two parameters define the minimum voltage threshold and the respective reset hysteresis. P09.n.02 cannot be set to a
value lower than P09.n.01. P09.n.03 this defines the tripping delay time of this protection.
P09.n.04, P09.n.05, P09.n.06
- The first two parameters define the maximum voltage threshold and the respective reset hysteresis. P09.n.05 cannot be set to a
value higher than P09.n.04. By setting P09.n.04 to OFF, the maximum voltage control is disabled. P09.n.06 defines the maximum voltage tripping delay.
P09.n.07
- Delay time for SRCx to return within the limits, used when an alternative threshold is not available. Normally shorter than P09.n.08, because the load is
not powered and supplying voltage is urgent.
P09.n.08
-
Delay time for SRCx to return within the limits, used when the load cannot be connected to an alternative line. Normally longer than P09.n.07, because
the load is covered and it is possible to wait for longer before conditions that voltage is stably re-established.
P09.n.09, P09.n.10
- Voltage threshold under which lowering is rapid because of a missing phase. Delay time for the missing phase is specified in P09.n.10.
P09.n.11, P09.n.12
- P09.n.11 These define the maximum imbalance threshold between the phases referred to rated voltage and P09.n.12 is the respective tripping
delay. This control may be disabled by setting P09.n.11 to OFF.
P09.n.13
- Maximum frequency tripping threshold; may be deactivated.
P09.n.14
- Maximum frequency tripping delay.
P09.n.15
-
Minimum frequency tripping threshold; may be deactivated.
P09.n.16
- Minimum frequency tripping delay.
P09.n.17
-
OFF
= voltage control SLCn in OFF mode is deactivated.
ON
= voltage control in OFF mode is active.
OFF+GLOB
= voltage control in OFF mode is
deactivated but the relay programmed with the global alarm function may intervene or not according to whether the mains are absent or present,
respectively.
ON+GLOB
= voltage control in OFF mode is activated but the relay programmed with the global alarm function may intervene or not
according to whether the mains are absent or present, respectively.
P09.n.18
- See P09.n.17 but referred to MANUAL mode.
P09.n.19, P09.n.20
- Conditional enable of the source line.
OFF
= The source line is normally available.
(Any other setting)
= The source line can be used only if
the set variable is active.
