Troubleshooting the 1756-HYD02 Module
What This Chapter Contains This chapter describes how to troubleshoot the 1756-HYD02 module.
Using the Status Indicators The ControlLogix Hydraulic Servo module uses a single bi-colored LED to
indicate module OK status and bi-colored LED indicators to show individual
feedback (FDBK) and drive (DRIVE) status for both axes.
During power-up, the module completes an indicator test. The OK indicator
turns red for 1 second and then turns to flashing green if the module passes all
its self tests.
The module’s status indicators are shown below.
