Jpdg - GE Mark VIeS System Manual

10.2.8 Configuration
The PPDA I/O pack uses configuration values for operation with desired PDM boards. The ToolboxST application provides
the correct options for the version of PDM hardware in use in a given system. A brief summary of the types of configurations
encountered are as follows:
•

JPDG:

− P28 feedback and diagnostics can be turned on/off. Keeping them on is recommended.
− The 24/48 V bus magnitude and centering tolerance can be configured, and the diagnostic associated with switched
branch circuit fuse status can be turned on or off.
• JPDE: The 24 V bus magnitude and centering tolerance can be configured, and the diagnostic associated with switched
branch circuit fuse status can be turned on or off.
• JPDS: The PPDA needs to know if P28R, S, and T can be present in a system. If it is indicated that one is not present, the
low voltage diagnostics for that power bus can be turned off.
• PPDA: The I/O pack needs to know what PDM boards are in the diagnostic daisy chain.
Note If two JPDS boards are present, it is recommended that one of the boards' inputs be disabled.
