IS230SNCIH6A Gas turbine electrical module

To start up the IMFEC1
module: 1. Apply power to the module. 2. Place the controlling module (MFP/MFC) in execute mode. Communication between the FEC module and the controlling module begins automatically if there are no configuration errors and the controlling module is in the execute mode. Upon start-up, all channels are marked bad quality. The controller sends the FEC module the transmitter configurations and the FEC module begins checking each channel. If the module detects a channel that is set up for an analog input (function code 132 only) and there are no other errors, the module marks that channel good quality and begins checking the next channel.

When the IMFEC11 module 

detects a channel that is set up for a smart transmitter (a configuration containing function codes 132 and 133), it does a check of that channel. It reads the actual configuration of the smart transmitter and compares it to the configuration within the controlling module. If these configurations are identical and there are no other errors, the FEC module marks that channel good quality. If the module detects a difference in the two configurations, the channel remains bad quality and a configuration mismatch status error occurs. The FEC module proceeds until it checks all 15 channels.

The IMFEC11 module 

periodically checks each channel having a smart transmitter configuration by trying to communicate with the transmitter on that channel. If a transmitter fails to communicate, the module marks the channel bad quality and a transmitter not responding status error occurs. If the transmitter resumes communication, the module does a configuration check (like the one made at start-up) of the device on that channel. The module marks the channel as good or bad quality depending on the results of the check
