Error Messages for HFO Systems Refer to Rear and Front of BRM, which doesn't exist for HFO systems.

Symptom

Error Messages for HFO Systems Refer to Rear and Front of BRM, which doesn't exist for HFO systems See Long Description An FE encountered the following Dynamic Disable Bias Faults while troubleshooting a HFO5 system: 2249159, 2249160, 2249161 (see below). Each of these errors refer to either "front of coil" or "rear of coil", and also " FRONT of BRM" and "BACK of BRM" . Evidently these are copies of the same errors from HD systems which use a cylindrical magnet and a BRM. Since the 0.7T Body coil has no "front" or "rear", and has no "BRM", the FE is at a loss as to where the system is pointing to in these errors. For HFO5 the errors need to specify top or bottom. These error messages, and there are undoubtedly others like them, must be rewritten to properly identify the problem area for HFO5. I suspect the same problem exists in previous incarnations of HFO as well, such as on HFO3 & HFO4. PQR 13090267 has been submitted. 2249159 lx-mr NSP SCP:../TrDriverMdsHWO.cpp 1683 Dynamic disable fault, Front of Coil short Dynamic Disable bias fault on front drivers. Possibly a short circuit load or a shorted diode in the dynamic disable switch boxes on FRONT of BRM . 2249160 lx-mr NSP SCP:../TrDriverMdsHWO.cpp 1691 Dynamic disable fault, Rear of Coil open Dynamic Disable bias fault on back drivers. Possibly a disconnected cable between the driver board and the dynamic disable switch boxes, or an open diode in dynamic disable switch boxes on BACK of BRM . 2249161 lx-mr NSP SCP:../TrDriverMdsHWO.cpp 1699 Dynamic disable fault, Rear of Coil short Dynamic Disable bias fault on back drivers. Possibly a short circuit load or a shorted diode in the dynamic disable switch boxes on BACK of BRM .
