Engine Sender Inputs
The DGC-2020ES has sender inputs dedicated to monitoring the engine fuel level, oil pressure, and
coolant temperature. These inputs are programmable to give the user flexibility in selecting the sender to
be used in an application. Information about programming sender inputs is provided later in this chapter.
Connections
Oil pressure sender connections are made at terminals 52 and 2 (sender common). Fuel level sender
connections are made at terminals 1 and 2. Coolant temperature sender connections are made at
terminals 53 and 2.
Compatible Senders
Oil pressure senders that are compatible with the DGC-2020ES include Datcon model 02505-00, Isspro
model R8919, Stewart-Warner models 279BF, 279C, 411K and 411M, and VDO models 360025 and
360811. Compatible Fuel Level senders include the Isspro model R8925. Compatible Coolant
Temperature senders include Datcon model 02019-00, Faria model TS4042, Isspro model, R8959, and
Stewart-Warner model 334P. Other senders may also be used.
Operation
A current is provided to each sender. The developed voltage is measured and scaled for use by the
internal circuitry. An open circuit or short circuit across the sender terminals will cause the DGC-2020ES
to indicate a failed sender.
Sender Programmability
BESTCOMSPlus ® software allows for the programming of sender characteristics. See Sender
Characteristic Curves, below, for more information.
Sender Characteristic Curves
The sender inputs of the DGC-2020ES can be customized to obtain maximum accuracy from the coolant
temperature, oil pressure, and fuel level senders.
The characteristic curve of each sender input can be configured with up to 11 points. Each point can be
assigned a resistance input value and a corresponding temperature (coolant temperature sender),
pressure (oil pressure sender), or percentage (fuel level sender) value. A sender slope setting
automatically orders the values in the resistance column according to whether the sender requires a
negative or positive slope. Sender curve points are automatically plotted on a curve in BESTCOMSPlus,
which can be printed.
Sender curve points configured in BESTCOMSPlus can be saved in the configuration file. The data for all
three senders is automatically saved with the DGC-2020ES configuration file.
Any changes made in BESTCOMSPlus to the sender points, can be reverted to the factory-default
values. A new settings file can also be created.
Curve Configuration
If the DGC-2020ES receives engine information from an ECU, the programmable sender parameters for
coolant temperature and oil pressure do not require configuration because they have no effect.
Configuration of sender parameters is appropriate for resistive senders only.
