Figure 2: OBE Function Diagram
Under DCM control, the process is:
●
●
●
The DCM provides a signal, which increments or decrements the OBE
output. Output signal is +12, 0, or -12 VDC.
A manually controlled Auto/Manual switch can disable the DCM
control of the OBE output. The status of this switch is reported back
to the DCM.
Two pushbuttons (+ and -) provide manual increment and decrement
control. These pushbuttons are functional in Auto and Manual modes.
This unit will operate in Manual mode without the DCM present. Power
supply must be present.
