Product Description

Exciter Attenuator module IS200EXAMG1B is used extensively in the EX2100 series. This board is mounted within the auxiliary cabinet and will typically be used to render low-frequency signals that are emitted from the exciter field ground detector module, the signals will then be sent to the sense resistor of the EXAM module. This process will provide current voltages across the resistors which are then dispatched back to the field ground detector.

There are two distinct differences between the IS200EXAMG1A and IS200EXAMG1B systems. Alterrex applications will need to use two IS200EXAMG1B models along with two EROC-enabled simplex ground detectors. The redundant systems used with this model will result in a test signal originating from the M2 or M1 controllers, these are used with the C controller which controls the switch that is used to flip between the two M controls.

There are several manuals that can be used with the IS200EXAMG1B module, these manuals are GEI-100467 and the GEH-6632, the GEI-100467 is a product-specific manual, and the GEH-6632 manual has information on other modules that the EXAM is used with as well as different dirhams which shows the module in the auxiliary cabinet.

Frequently Asked Questions about IS200EXAMG1B

What boards do the IS200EXAMG1B models work in conjunction with?

The main board that the IS200EXAMG1B works with is the EGDM which helps detect ground voltages, but the IS200EXAMG1B board also works with the EROC board.

The EXAM boards can be used in Alterrex applications. How are the boards used in Alterrex applications?

When being used in Alterrex applications two EXAM boards must be used. One of the board is used for generator field circuits, and the other is used for exciter field circuits.

Are there differences when the IS200EXAMG1B board detects more than one ground in the field?

Yes! If the IS200EXAMG1B model detects the existence of one ground damage to the rotor is likely not to occur, but if two or more grounds in the field are detected the winding path causes thermal and magnetic imbalances which will damage the rotor and other metallic parts.

What is the wiring board type for the IS200EXAMG1B model?

The wiring board type for the IS200EXAMG1B model as stated in the GEH-6632G EX2100 Excitation Control User's Guide is a Bridge and Protection Board/Module.

Reviews For IS200EXAMG1B

Internal Review

(5.0)

The IS200EXAMG1B has a low rate of failure in EX2100 and EX2100e Excitation Control Systems and is easily repairable when needed. Because Alterrex applications may use two of these in the system it is important to keep multiple spares on hand in case of defect or failure. - AX Control Tech Team
