Genie error code 0x2233 — Encoder Limited Operating Strategy (LOS)
Message on the display: Encoder Limited Operating Strategy (LOS)
Code 0x2233 occurs in machines: Genie S-85 XC FE, S-85 XC E, Z-60 DC, S-60 DC.
warning / function limited
Flash pattern 9-3 (flash code 0x93).
Description from the Genie service manual, in the original wording.
Effect on the machine: LOS Mode. Fault Action: None, unless a fault action is programmed in VCL.
Possible causes
- Limited Operating Strategy (LOS) control mode has been activated as a result of either an Encoder Fault (flash code 3-6) or a Stall Detected fault (flash code 7- 3).
- Motor encoder failure.
- Bad crimps or faulty wiring.
- Vehicle has stalled.
What you can do
Switch the machine off with the emergency stop and switch it on again. If the code comes back, do not use the machine and call service.
Solution from the manual
Set: Either the Encoder Fault (flash code 3-6) or Stall Detected (flash code 7-3) was detected. If the parameter LOS Upon Encoder Fault = On and the Interlock has been cycled, then the Encoder LOS (flash code 9-3) control mode is activated, allowing limited motor control (limp home mode). Clear: Cycle KSI or, if LOS Mode was activated by the Stall Detected fault, clear by ensuring the encoder senses the proper operation, Motor RPM = 0, and Throttle Command = 0.
