Leader Tilt Angle X-Axis Signal Fault
Diagnosis & fix steps
LOGIC: Dual-Axis Leader Inclinometer Channel X CAN Bus Dropped.
ACTION: Check 24V supply and CAN bus termination resistors (~120Ω per node) at mast junction box +4V. Inspect twisted-pair signal wiring inside flexible mast umbilical loop.
Red Seal field insights
Verticality Control: High-precision piling requires active X/Y inclination feedback to regulate mast alignment; missing CAN telemetry freezes automatic mast vertical positioning.
