Detailed list of error codes and possible resolutions

SkyStopper Home

This page is primarily to show the different error announcements that SkyStopper can send. In general you will not need to use this, because the error either means try again or don't try again, however, some error codes need to be corrected, and will be repeated until corrected. One of these is code 9, platform jammed or overloaded. Another code is F which means IR input received garbled. That means you are not pointing the remote at the pick-up. Some other useful description of some terms and concepts is on the features page.

Code 0: not used

Code 1: factory use only

Code 2: factory use only

Code 3: middle tone is very high. Display shows '3'. This error occurs when a command to seek center or end is given before the platform has been initialized. Use a short press on OK to get the platform to find the limit switch. After that, seek commands will work.

Code 4: middle tone is very high. Display shows '4'. The platform attempted to sense the limit switch but it was already at the limit. The platform could not advance forward to get clear of the limit switch, within the timeout period.

Code 5: not used

Code 6: not used

Code 7: middle tone is very high. The platform failed to end up at its destination within the required timeout. Ensure the wiring is secure or contact the factory for service.

Code 8: not used

Code 9: middle tone is very high. This indicates that a command to seek start, middle, or end was issued but the platform has not been initialized yet. Ensure the platform is not obstructed, and that the linkage is properly installed, then press a short tap on OK to start the initialization process.

Code 10: middle tone is high. Display shows 'A'. This indicates that the limit switch is still detected after the motor has moved far enough to be clear of it. Try to seek initialization one more time (very long press on OK). If this fails, inspect to see if the platform is over-rewound or the cables are connected properly, and that nothing is jammed in the limit sensor.

Code 11: middle tone is high. Display shows 'b'. An unsuccessful UNDO command was attempted. This indicates that UNDO is not possible, based on the current state and position of the platform.

Code 12: middle tone is high. Display shows 'c'. Undo is not supported for certain situations. This was a request to undo the initialization.

Code 13: not used

Code 14: not used - factory test mode only

Code 15: not used

Code 16: not used

Code 17: not used

Code 18: middle tone is medium. Display shows '2' with decimal point on. This indicates garbled infra-red input was received. Reposition the remote and try the press again.

Code 19: middle tone is medium, Display shows '3' with decimal point on. The Infra-Red remote sends a special code for each different button. When the button is held, it sends a 'same button again' repeat code 10 times per second. The same repeat code is used for all of the buttons. Therefore the system needs to know what button is being repeated by sensing that at the beginning. This erorr indicates you are holding down the remote button, but the control does not know which button because the initial part of the IR sequence when the button was pressed was never received by the control unit.

Code 20: middle tone is medium, same as code 21, display shows '4' with decimal point on. See code 21 description.

Code 21: middle tone is medium. Display shows '5' with decimal point on. This is a triple-axis error only. It indicates that an attempt to control the guide actuator was initiated but the guide has not been centered since power-up and was not left in a centered position when powered off. Press and hold '1' to release the lock, then while viewing the guide's motion, center it, and hold '1' again to lock in the correct center position.

Code 22: middle tone is medium, same as code 21, display shows '6' with decimal point on. See code 21 description.

Code 23: middle tone is medium, same as code 21, display shows '7' with decimal point on. See code 21 description.

Code 24: middle tone is medium. Display shows a '8' with decimal point on. The triangle+ or triangle- button was used with a previously entered numeric argument. An attempt was made to slew the platform position beyond the range of permitted travel. The command was ignored.

Code 25: middle tone is medium. see code 24. Display shows a '9' with the decimal point on.

Code 26: not used

Code 27: not used

Code 28: middle tone is medium. Display shows 'c' with the decimal point on. like code 24, but the request was made to adjust the declination via the guide actuator and was out of range.

Code 29: middle tone is medium. Display shows 'd' with the decimal point on. like code 28.

Code 30: middle tone is medium. Display shows 'e' with the decimal point on. An attempt to reprogram the IR remote codes was received but the protocol has not been followed. The attempt is ignored. This is an advanced function for use only when the original remote control has been lost. Contact factory for details of the process if the remote is lost, to get another or to reprogram the SkyStopper control to accept codes from a new remote you already have.

Code 31: middle tone is medium. Display shows 'F' with the decimal point on. An IR input was sensed which cannot be found in the table. Likely the input was garbled. Reposition the receiver or your hand holding the remote, so that the signal can be reliably received.

Code 32: middle tone is low, Display shows '0'. The green button was pressed (for fine tuning of the tracking rate) while the SkyStopper is not tracking. It cannot tune the rate unless tracking.

Code 33: not used

Code 34: not used

Code 35: middle tone is low, display shows '3'. internal software error detected while accessing stored settings. Should never happen.

Code 36: middle tone is low, Display shows '4'. See code 35.

Code 37: middle tone is low, Display shows '5'. See code 35.

Code 38: not used

Code 39: not used

Code 40: not used

Code 41: Display shows 9, intermediate tone lower than first tone. This code indicates that the platform has detected an overload or a jam. The motor is not responding to the controller command to move. The controller removes all power from the motor for 2 seconds and then tries again. This is to prevent possible overheating of the motor which might happen if the power is not removed. Determine the cause of the jam and correct it. If the platform has rewound past 0 and missed the limit switch sensor, it will jam and produce this code. That can only happen if the platform is operated without sufficient weight on it and it came off the bearings while rewinding. Remove the linkage, manually spin the carriage several turns to get it back in range, and connect the linkage, put some weight on the platform and rewind it again. If this error persists, check the cables and call for service if damaged.

Code 42: middle tone is lower than the first tone, display shows 'A'. The software has detected that the programmed settings for the tracking tables are corrupt. Contact factory to resolve. This should never happen.

Code 43: middle tone is very low, display shows 'b'. The guide actuator was not left in a known state at power-off. See error code 21 for details to resolve this.

Code 44: not used

Code 45: middle tone very low, display shows 'd'. An attempt to adjust the platform was made, while the limit switch is sensed. The attempt was ignored. See code 10 to resolve.

Code 46: not used

Code 47: middle tone matches last tone, display shows 'F'. This indicates a software error which should never happen.
