Symptom
Unable to Scan with the "1.5T 8Ch TR Knee Array" due to "Multicoil Bias Fault Detected - Open Circuit" Always on Channel 6 See Long Description Unable to scan with the "1.5T 8Ch TR Knee Array" due to "Multicoil Bias Fault Detected - Open Circuit", always on Channel 6. (See below for a copy of the logged error from the site). This doesn't happen with any other coil, and it occurs with the coil plugged into either the "A" or "B" Excite HD LPCA coil ports.

An open circuit fault occurs when the actual value is less than the pre-defined limit. Check system cables, connectors, coils and configurations. Re-seat all coil connectors. The mask of all failed channels indicates additional channels with the same fault - convert the hex number to a bitmap to decipher the mask, with channel 1 indicated by the least significant bit and channel 16 indicated by the most significant bit. For example, a mask of 0x3c converts to 0011 1100, meaning channels 3, 4, 5, and 6 all experienced the same failure. The key at the bottom of the error message shows the MC driver bias channels provided by the Driver Module used with each mult
