Error message

2252301 Multicoil Bias Fault Detected - Open Circuit. Try re-seating all coil connectors. MCDx Channel x of y, counting from 1 Value x mA Limit y mA See Long Description for Extended Error 2252301 MRI_GB_OW0 NSP SCP:DCB 816 Multicoil Bias Fault Detected - Open Circuit. Try re-seating all coil connectors. MCD1 (or MCD2) Channel 1 of 16, counting from 1 Value: 2 mA Limit: 298 mA Mask of failed channels: 0x1 Ch 1-8 : Legacy MC Conn Ch 17-24 : Conn A Ch 25-32 : Conn B-> Extended Error: This fault was detected by the Driver Module. 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
