VOAC Hydraulics ICM435-0191 Joystick Controller

The VOAC Hydraulics ICM435‑0191 is a rugged industrial joystick controller used to transmit operator input to hydraulic or electrohydraulic systems. Common failure points for this class of equipment include worn potentiometer tracks, degraded mechanical linkages, power supply voltage drops, and insulation breakdown in the signal wiring harness. Begin troubleshooting by verifying that the unit receives its rated input voltage (24 V DC or 120 VAC as specified), checking all connector pins for continuity and proper polarity, and inspecting the joystick mechanism for physical wear or binding; then review any diagnostic error codes displayed on the controller’s panel or communicated via its communication interface.[oss-gpt-20b]
