How to fix Manitowoc E05 (Prohibited Length Range) during telescoping?

TR-512 · Troubleshooting
E05 error indicates boom length sensor malfunction or telescopic section positioned in prohibited range between preset limits.
The Manitowoc E05 error occurs when the boom length feedback system detects the telescopic section is positioned within a prohibited range or when length sensors malfunction. First, check the boom length sensor cables for damage, corrosion, or loose connections at the telescope cylinder and main control module. Clean sensor contacts and verify proper cable routing away from hydraulic lines.
