1. Input Select
It is sometimes desirable to change the input of the DNGP from standard 4-20 mA to user defined digital
inputs, or Modbus Control. This can be accomplished through the INPUT CONFIGURATION MENU using
the INPUT SELECT option. The diagram below, and on the following pages, show the actual process
needed to configure the inputs of the DNGP when already operating from the TOP LEVEL SETUP SCREEN

2. Split Control
In some applications, split range control is needed instead of the standard 4-20 mA range. The DNGP can be
accomplish this feat through the INPUT CONFIGURATION MENU using the SPLIT CONTROL option. The DNGP
has the option to enable or disable the split control feature or set the upper and lower split limits with 4 mA
minimum range in 1 mA increments.
