5.2 ELEVATION MOVEMENT RELATED ERRORS

5.2.1 E1 – ELEVATION REVERSED ERROR
OVERVIEW
When elevation movement is commanded (e.g. elevation up) the elevation position feedback is expected to change
in the correct direction (e.g. increase in pot value for an elevation up command). If the elevation position feedback
changes in the opposite of the expected direction (e.g. elevation command up and elevation feedback decreases) a
reverse elevation error (E1) is flagged.
PROBLEM IDENTIFICATION
The movement can be directly controlled and the elevation position feedback can be directly read in the hardware
test. To observe the elevation error, enter the hardware screen (see HARDWARE TEST SCREEN section in this document).
Use the elevation up/down keys to directly control the elevation movement (within the travel limits of the elevation
mechanism). Observe the elevation position feedback displayed in the elevation window. Use the below guide to
identify the problem.
CORRECTIVE ACTION
Elevation Moving In Wrong Direction (perform actions in the order displayed, perform next action if previous did not work)
• Ensure correct signal is being sent to Motor Controller board by pressing
observing elevation LED's correctly corresponding to correct elevation keys pressed. If failure occurs for this step
check ribbon cable and then the Motor Controller board.
• Check system with a known good ribbon cable.
• Check elevation motor for proper operation (plug into known good system and ensure elevation is moving in
correct direction). Wiring of elevation motor may be incorrect.
• Check failed elevation motor, Motor Controller board, ribbon cable with a known good console.
Elevation Feedback Reversed
• Reverse the elevation direction in the firmware setup screens (see Manual Calibration screen in this document).
• Calibrate Elevation
• Calibrate the elevation as outlined in the System Calibration Procedure in this document.
