Crank Settings
The DGC-2020 can be programmed for either cycle or continuous engine cranking

A

. Cycle cranking

provides multiple engine starting attempts

B

. Each starting attempt consists of a fixed interval of engine

cranking

C

followed by a rest interval of the same duration. Continuous cranking

D

provides a single,

extended engine-starting attempt.
The DGC-2020 uses the engine speed signal (supplied by a magnetic pickup (MPU) or the generator
frequency) and the Crank Disconnect Limit setting

E

to detect engine startup (and determine when engine

cranking can be stopped). The Crank Disconnect Limit setting is expressed as a percentage of the
nominal engine speed.
If desired, cycle or continuous cranking can be delayed after initiating engine startup. During this delay

F

,

the Pre-Start output closes to energize the engine glow plugs or pre-start lubrication pump. The Pre-Start
output can be configured to open upon the conclusion of engine cranking or remain closed as long as the
engine is running

G

.

The Pre-Start can be configured

H

during the resting state. If Preheat Before Crank is selected, the Pre-

Start output will be closed for a time equal to the Pre-crank delay time prior to re-entering the cranking
state. If the Pre-crank delay setting is longer than the rest interval, the Pre-Start output will be closed for
the entire rest time.
Under normal operation, engine rpm is used to determine crank disconnect. The Oil Pressure Crank
Disconnect

I

provides a secondary indication that the engine is running so that the starter will be

disconnected even if no engine rpm sources are functioning. When enabled, oil pressure is used as a
check of whether the engine is running. If the engine oil pressure is above the threshold

J

, the starter will

be disconnected from the engine.
BESTCOMSPlus engine cranking settings (DGC-2020, System Parameters, Crank Settings) are
illustrated in Figure 4-22.
