12.0 OEM ENGINE CONTROL
12.1 OEM ENGINE CONTROL can be used as an engine start-up in applications
where the DE-3000+ is used to signal instructions to a controller, rather than
directly turning on and off fuel and ignition as is done in AUTO START. To use
the OEM ENGINE CONTROL option, select and configure it in the PC terminal
program under the Program Global Variables screen. The four output modules
on the power supply board should be configured as follows for OEM ENGINE
CONTROL: Out 1 for Driven Equipment Ready (DER), Out 2 for Start/Run
Signal, Out 3 Auxiliary if necessary, Out 4 for Pre/Post Lube. OEM ENGINE
CONTROL begins its sequence when an auto start command is sent to the DE-
3000+. The various programmable timers for each module on the power supply
board output are shown below.

12.2 The OEM ENGINE CONTROL sequence must begin from an engine stopped
condition. When a DE has been configured for OEM ENGINE CONTROL and an
auto start is signaled by grounding the ‘R’ terminal on the terminal board (or
a command from the HMI), Lube turns ON, the Crank/Multi-Start disconnect
timer starts, and the ‘Delay before ON’ timers for the Start/Run Signal and the
Auxiliary output begin counting down. DER remains ON from the time the auto
start signal is sent to the DE-3000+ until a manual stop or fault occurs. All class
A setpoints are monitored and class B and C timers begin once the auto start
signal is received.
12.3 Once the engine speed has surpassed a specified RPM, the Lube will turn OFF.
This Pre Lube Disconnect must occur before the Pre Lube time expires. If it
does not, a PRELUBE FAULT will occur and all four outputs will turn OFF and
the sequence will terminate.
