Electrical and mechanical checks
Supply, command, travel and valve linkage require verification together.
System component / actuators
A SIGNAL MUST BECOME MOVEMENT.
Actuators connect electronic control decisions to hydraulic valve position.

HIU TECH / TECHNICAL SCOPE01—03
Symptom overlap
An actuator symptom can also arise from sensors, controller outputs, valve resistance or unavailable network conditions.
Attendance required
Conclusive diagnosis requires an engineer on site to measure temperatures, pressures, flow, electrical supply and control response under operating conditions.
