FUNCTIONAL DESCRIPTION:

IS200ESELH2AAA is an Exciter Selector Board manufactured and designed by General Electric as part of the EX2100 Series used in GE Excitation Turbine Control Systems. The IS200ESEL Exciter Selector Board (ESEL) mounts in the control rack and receives six logic level gate pulse signals from its corresponding master I/O (EMIO) board. It then uses the pulse signals to drive six sets of cables which are distributed to the exciter gate pulse amplifier (EGPA) boards. The EGPA boards are mounted in the Power Conversion Cabinet. Three groups of ESEL boards are available to support increasing redundancy levels:

• ESELH1 contains a single bridge driver controlling one PCM
• ESELH2 contains three bridge drivers controlling three PCMs
• ESELH3 contains six bridge drivers controlling six PCMs

For simplex systems, only one ESEL is necessary, but if redundancy control or online repair is required, then two ESELs are supplied. Either ESEL 1 or ESEL 2 can be active depending on which controller, M1 or M2, is active as determined by controller C. Refer to the figure below. ESEL 1 is always driven by M1, and ESEL 2 by M2. Controller M1 is the default.

APPLICATION DATA:

There are no jumpers or test points on the board. Connectors P1 and P2 connect to the VME backplane and are not defined in this document since these individual pin signals are not normally checked during troubleshooting.  Three green LEDs at the top of the front panel provide status information as follows:

• Power is on the board.
• Board is active (enabled by the signal from control C).
• The board is gating (driven by gate inputs from EMIO).
