1. Crank Disconnect Limit - This parameter defines the engine rpm threshold in percentage of rated rpm
at which engine cranking should cease.
2. Pre-Crank Delay - This setting specifies the amount of time for pre-cranking to occur. The PRE relay
is closed during this time. This setting is typically used for engine preheating and/or pre-lubrication.
3. Prestart Contact Config - Select whether the PRE relay should remain closed after the engine starts,
or if it should open.
4. Prestart Rest Configuration - There may be situations where it is desired to have the PRE relay
closed during engine cranking but open for all or part of a crank resting cycle. Configure this
accordingly. Refer to the appropriate paragraphs in Section 4, BESTCOMSPlus
® Software, for
additional information.
5. Oil Pressure Crank Disconnect - This setting provides an alternate method of determining conditions
under which crank disconnect should occur. If the machine has no magnetic pick up (MPU) for rpm
detection or a failed, MPU, and the DGC-2020 cannot read generator frequency to obtain rpm
information, it will use oil pressure as criterion for crank disconnect. This will prevent long starter
engagement if the engine starts but the DGC-2020 cannot determine engine speed for crank
disconnect purposes.
6. Cranking Style - Select Cycle Cranking or Continuous Cranking.
a. Cycle
i. Number of Crank Cycles - This parameter defines the number of crank cycles if
Cycle is selected as the crank style. Note if NFPA level 1 or 2 has been selected
under SYSTEM PARAMETERS > NFPA LEVEL, this cannot be programmed; it is
set to a fixed value to satisfy the NFPA compliance.
ii. Crank Cycle Time: This parameter defines the length of the crank cycle if Cycle is
selected as the crank style. Note if NFPA level 1 or 2 has been selected under
SYSTEM PARAMETERS > FPA LEVEL, this cannot be programmed; it is set to a
fixed value to satisfy the NFPA compliance.
iii. Rest Time: This parameter defines the duration of the rest time if Cycle is selected
as the crank style. Note if NFPA level 1 or 2 has been selected under SYSTEM
PARAMETERS
NFPA LEVEL, this cannot be programmed; it is set to a fixed
value to satisfy the NFPA compliance.
b. Continuous
i. Continuous Crank Time - This parameter defines the length of the crank cycle if
Continuous Cranking is selected as the crank style.
7. Off Mode Cooldown Enable - When this setting is disabled, pushing the OFF button stops the unit
immediately. When enabled, pushing the OFF button once will start a cool down cycle and the RUN
LED will flash. The unit will complete the cool down cycle and stop in OFF mode. If the OFF button is
pushed a second time, the unit stops immediately.
8. Restart Delay - This setting specifies the amount of time to delay restarting an engine after a normal
shutdown. This setting is used to prevent stress from attempting to start while the engine is still
spinning down.
