Brake Coach Gauge
If the charge/discharge display, the brake event data, or the regen event level data message is missing for less than 5 seconds, the IPC defaults the brake coach gauge to the last indication state, based upon the last message received.
If the charge/discharge display, the brake event data, or the regen event level data message is missing for 5 seconds or longer, the IPC defaults the regeneration (circular) arrows off in the regenerative braking active display or the brake event feedback display off in brake coach gauge.
