Note: This menu is divided into 24 sections, which refer to 24 possible digital outputs OUT01…OUT24 that can be managed by DCRG8F, of which OUT01..OUT08 on the basic device and OUT09…OUT24 on any
expansion modules.
P04.n.01
– Choice of the function for the selected output (see programmable output function table on page 14).
P04.n.02
– Channel number associated with the function programmed in the previous parameter. Example: If the output function is set to Alarm Axx and you want this output to be energised for alarm A31, then set
the value to 31.
P04.n.03
– Sets the state of the output when P04.n.01 is inactive (OFF):
NOR
= Output de-energised;
REV
= Output energised.
M03 – STEPS (STPn, n=1…32) UoM Default Range

P02.21
– Rated voltage of the system. Value used for the full scale of the bar graphs and setting the voltage thresholds, expressed as a percentage.
If set to Aut, then the value of P02.08 (rated voltage of capacitors) is used.
P02.22
– Type of system voltage. Depending on the setting of this parameter, the appropriate wiring diagrams must be used. See at the end of the manual.
P02.23 ... P02.27
– Data of VTs eventually used in the wiring diagrams.
P02.28
– Selection of step connection mode
Standard
= Normal operation with free selection of the steps.
Linear
= The steps are connected in progression from left towards right only, following the step number and according to the LIFO (Last In First Out) logic. When the system steps are of different ratings,
the controller will not connect a step if the set-point value would be exceeded.
Fast
= Fast switching for use with static/thyristor modules and parameter P03.n.02 set to Static.
P02.29
– After having closed one step output, the measurement acquisition is suspended for the number of periods (cycles) specified by this parameter, in order to allow the external static module to connect the
capacitors. This function avoids regulation oscillations. Set this value according to the technical characteristics (closing time) declared by the manufacturer of the static module.
P02.30
– Enables the setting of the setpoint as Tangent of displacement phase angle (Tanphi) instead of Cosine (Cosphi). Used as a reference by the energy providers of some European countries.
P02.31
– Value of the Tanphi setpoint. Negative Tanphi values correspond to capacitive Cosphi.
P02.32
– Sensitivity mode selection:
Proportional
= The sensitivity delay time is inversely proportional to the reactive power required.
Fixed
= The sensitivity delay time is fixed irrespective of the reactive power required.
P02.33
– Tan
setpoint used when the system is granting active power to the supplier (greater precision around the setpoint but greater number of operations).
P02.34
– Angular setpoint for compensating for the phase variation introduced by a transformer between the voltages on the primary winding and those on the secondary winding.
P02.35
– Delay time between the switching of an output and the next one for traditional steps (not valid for static steps).
Note: This menu is divided into 32 sections that refer to 32 possible logic steps STP1…STP32 which can be managed by the DCRG8F.
P03.n.01
– Weight of step n, referred to the value of the smallest step. The number that indicates the multiple of the power of the current step with reference to the smallest set at P02.07. If set to OFF, the step is
disabled and will not be used.
P03.n.02
– Type of device referred to the switching of the step.
Contactor
= Electromechanical switching by contactor. For this step, the reconnection time is used.
Static
= Electronic switching by thyristor module. For this step, the reconnection time is not considered. Used for Fast power factor correction.
Fixed
= Step always connected. The reactive power for this step is not considered mathematically in the calculation of the power factor correction electrical parameters. This function is typically used to
correct the secondary winding of the medium transformer if present.
Static-485
= as Static type, but the steps are commanded through RS485 communication port (EXP1012 optional module). This function is available only for the command of thyristor modules DCTL
series. For details see chapter COMMAND OF DCTL SERIES THYRISTOR MODULES VIA RS485 BUS.
P03.n.03
– Defines whether the steps are three-phase or single-phase type and what phase the steps are connected to.
