Service Information Letter SIL- 3201-A
Parameter Update — Controls
Units Affected: Certain AH model units built from December 2020 to February 2025. Verify your unit
is affected by reviewing the attached list or accessing Altec Connect.
Background: Altec has learned the single axis joystick controls on affected units may experience nuisance system error lights and parameter faults. This could lead to reduced functionality of interlocks.
These joysticks are at the upper controls on AH75B/85B/100B units and at both the Upper and Ground
controls on AH125A-S units.
Customer Action: Contact Altec to schedule an update within 180 days of receipt of this notice or at
the next scheduled service interval. Completing this work will improve the functionality of the controls.
Warranty for this repair expires July 25, 2027.
Subsequent damage due to failure to perform the required action(s) in the time period allowed will not be
covered by warranty.
Ask your service provider to check for any outstanding notices at your next appointment.
Requirements: The repair is estimated to take 3 hours and 1 person to complete. This update must be
completed by Altec using an AXIS Service Tool.
Altec Service technicians will need the below kit and individual part(s), by model, prior to going out to the
unit. The individual controller quantities listed are recommended to have on-hand before inspecting the
unit. It may not be required after the parameter update and unused parts can be returned.
