Basler Electric DGC-2020 - Manual (Page 345)

xxii. PF Setpoint - The set point for the kvar controller when it is in power factor control
mode and the PF Setpoint Source is set for User Setting. The DGC-2020 will
maintain this power factor when the generator is paralleled to the utility as indicated
by the parallel to mains (ParToMains) logic element in BESTlogicPlus Programmable
Logic. Note that a negative setting is used to specify leading PF and a positive setting
specifies lagging PF.
xxiii. PF Analog Max - This setting defines the value of PF that is requested when the PF
Setpoint Source is set to an analog input and the input is at its maximum. This
parameter cannot be configured when the PF Setpoint Source is set for User Setting.
Note that a negative setting is used to specify leading PF and a positive setting
specifies lagging PF.
xxiv. PF Analog Min - This setting defines the value of PF that is requested when the PF
Setpoint Source is set to an analog input and the input is at its maximum. This
parameter cannot be configured when the PF Setpoint Source is set for User Setting.
Note that a negative setting is used to specify leading PF and a positive setting
specifies lagging PF.
g. Configure Demand Start/Stop related parameters (if Demand Start/Stop is used)
i. Configure Demand Start/Stop parameters.
The Demand Start/Stop parameters are found in BESTCOMSPlus ® under
SETTINGS EXPLORER > DGC-2020 > MULTIGEN MANAGEMENT > DEMAND
START/STOP. See Figure 7-61.

There are two demand start levels and timeouts. This allows the user to set up a
lower system power level with a long timeout for normal generator starts, but if the
system power level exceeds a higher level for a shorter time (e.g. a machine has an
alarm shut down or some other abnormal system power phenomenon occurs)
machines can be brought on quickly.
Set up the individual parameters according to:
(1) Demand Start/Stop Enable - Select Enable to turn on the demand start/stop
functionality.
(2) Delayed Start Level 1 (PU) - This setting defines the level (in Per Unit) at
which the sequence for starting another machine should occur. Once the
Start Level 1 Timeout has expired, another machine will be started.
(3) Start Level 1 Timeout - Set setting defines the desired delay before starting a
machine when the system per unit power level has exceeded Delayed Start
Level 1.
