Winco DGC-2020 - Manual (Page 97)

Exercise Timer
The exercise timer is used to start the genset at a predetermined time and run for the user-defined period.
The mode
A defines how often the genset will run. If monthly is selected, you must select the day of the
month B to start. If weekly is selected, you must select the day of the week C to start. Settings for Start
Hour D and Start Minutes E may also be defined. The Run Period Hours F and Minutes G define how long the
genset will run each time. If Run with Load H is enabled, the DGC-2020 will close its GEN breaker during
the RUN time.
Contact inputs and outputs can be assigned to the function. Refer to Section 5, BESTlogic+
Programmable Logic,
for more information.
BESTCOMSPlus exercise timer settings (DGC-2020, System Parameters, Exercise Timer) are illustrated
in Figure 4-24.
Figure 4-24. Exercise Timer Settings
A
Mode: Monthly, Weekly, or Daily.
B Start Day Of Month: Adjustable from 1 to 31 in 1 day increments.
C Start Day Of Week: Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, or Saturday.
D Start Hour: Adjustable from 0 to 23 in 1 hour increments.
E Start Minute: Adjustable from 0 to 59 in 1 minute increments.
F Run Period Hours: Adjustable from 0 to 23 in 1 hour increments.
G Run Period Minutes: Adjustable from 0 to 59 in 1 minute increments.
H Run with Load: Enable or Disable.
Sensing Transformers
Three sets of transformer settings configure the DGC-2020 for operation with a specific system. These
settings, along with the generator voltage, generator current, and bus voltage detected by the DGC-2020,
enable the DGC-2020 to accurately meter system values, offer generator protection, and synchronize the
generator with the bus (style number xxxxxxxAx only).
Generator PT Settings
The generator PT settings establish the nominal primary
A (generator side) and secondary B (DGC-2020
side) voltage levels at the generator voltage-sensing transformer.
Generator CT Setting
The generator CT setting
C establishes the nominal, primary (generator side) current level at the generator
current sensing transformer. The secondary value of the generator CT is dictated by the style number of
the controller. A DGC-2020 with a style number of 1xxxxxxxx uses a nominal CT secondary rating of 1
Aac. A DGC-2020 with a style number of 5xxxxxxxx uses a nominal CT secondary rating of 5 Aac.
