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
