DS215DMCBG1AZZ03A is a Drive Board and is part of the GE Speedtronic Mark V gas turbine control system. 

There are five vertical cable connectors on this densely packed board (four male and one female).

There are also three vertical header connectors, three stab-on connectors, and over twenty jumper switches.

In the upper left quadrant, there is a reset switch that allows you to reset the board without turning it off first.

The LED indicators tell the operator of the board's status during operation.

Enable Input

The Enable discrete input allows the host controller to enable or disable the power output

stage of the controller and reset faults. The Enable input must be active to run the servo

motor. This Enable hardware input works in tandem with a logical (software) enable register

called the Power Output Stage Enable (POE) register. The POE register will allow current to

flow into the motor only when set true and no faults are present on the controller. Since a

Lost Enable (LE) fault is generated when this hardware enable input is false, ensure that

POE=1. the hardware enable input is true, and all faults have been cleared (RSF register) to

activate the power stage of the controller.

The current state of the Enable input can be queried using the Fault Code (FC) register in

the terminal window. The Enable input should be connected as shown in the connection

diagrams in Section 3.6.10. The internal schematic for the enable input circuit is shown below.
