Hardware Tips and Specifications

The GE Contactor Driver Board DS200CDBAG1 opens and closes the contactors in its larger Mark V Series Autodrive assembly. Before touching the board for installation, be sure to disconnect power to the drive and test the board to ensure that there is no power in the board. Also, do not remove the board while the drive is powered. Static electricity can damage the board. Use a grounding strap to work on the board and store the board in a static protection bag. the DS200CDBAG1 has a jumper. jp1 is a 3-pin jumper for factory test purposes only. Keep pins 1 and 2 covered for normal operation. When pins 2 and 3 are covered, it is for factory use only. The DS200CDBAG1 also has a potentiometer to control the amount of current applied to the contactor coil. This is set at the factory and it is best practice not to change it. Voltage limiting in the assembly of this DS200CDBAG1 Mark V Turbine Control System series product is handled in the same manner as most General Electric Speedtronic products; accepting a variety of voltage-limiting hardware components including capacitors, rectifiers, diodes, and integrated circuits through its internal assembly. In addition to this, the base board and components of this DS200CDBAG1 product receive the normal level of protection from daily wear and tear and insulation due to its normal style of PCB protective coating, which wraps and protects the individual DS200CDBAG1 board hardware components according to their functional priority.

The DS200CDBAG1 also features test points that can be used to test board operation. One test point is a common reference point for the board. One test point is a 15 VDC test point referenced to the common reference point. One test point is for contactor driver reference voltage. connector 1TB on the DS200CDBAG1 board consists of four sections (1TBA, 1TBB, 1TBC, and 1TBD). Carefully note the location of the connector on the board and use a screwdriver to pry the sections apart. The connectors on the replacement board may be in different locations, so care must be taken to plug the sections into the correct connectors. There is also a fuse available for this DS200CDBAG1 Mark V series assembly; this fuse is designated in the original instruction manual material as a 4 amp, 125 V, 2AG slow blow fuse and can be replaced if it continues to blow (this is usually applicable to any DS200CDBAG1 board assembly).
