Error message
2252303 Multicoil Bias Fault Detected, Short Circuit. Channel X of Y See Long Description Error: 2252303 Host: lx-mr Process: NSP File: SCP:DCB Line: 1030 Multicoil Bias Fault Detected - Short Circuit. Try re-seating all coil connectors. MCD1 Channel 3 of 16, counting from 1 Value: -310 mA Limit: -301 mA Mask of failed channels: 0x3c 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. A short circuit fault occurs when the actual value is more negative than the pre-defined limit. This could be caused by a shorted diode in the coil or a short elsewhere in the system. Check coil, system cables, connectors and configurations. 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 multicoil
