Same with the indicators for the various doors associated with Coudé Rotator.
Coudé indicators
Coudé Emergency Stop
This indicates the status of the Emergency Stop devices associated with the Coudé Axis. The indicator also functions as a GOTO button that will open the Coudé E-Stop Display.
Cabinet Environmental
This indicates if there is an issue with cooling in any of the drive or electronic cabinets that are part of the Coudé Motion Control System.
Cable Wrap Alignment
This indicates if there is a mis-alignment between the Coudé Rotator and cable chain.
Azimuth Hard Stops
The hard stops are part of the final limit function of the Coudé Azimuth rotation. During most of the range of motion of the Coudé Azimuth the hard stops are in the undeployed ‘down’ state. As the axis nears the end of travel the hard stops will deploy (pop up) to stop the axis from exceeding the mechanical limits of the system.
The final limits should activate prior to the mechanical limit being reached but the hard stops function as a mechanical backup.
The hard stops are monitored in three zones. The non-deploy zone where the hard stops must be in the non-deployed (down) state. Then there are the two deploy zones, lower end and upper end, in which the hard stops must be deployed (up).
The safety function monitors this and will stop the Coudé Rotator if the hard stops are not in the correct position.
Azimuth Final Limits
The Coudé Azimuth final limits monitor the position of the Coudé Rotator to ensure it does not exceed mechanical limits.
If the Coudé Azimuth has exceed the allowable final limits the Rotator must be manually moved out of the final limit. Connect an HHD and manually drive the rotator out of the limit while visually monitoring the motion.
Azimuth Speed Limit
The Coudé Azimuth rotation speed is monitored for three conditions:
below maximum speed
below safely limited speed
Safe Stop deceleration curve monitoring
If any of the limits are exceeded the Coudé Rotator will stop.
Reset requires that the associated Kuebler encoder be reset.
Azimuth Stop Ramp
Cabinet Doors Closed
The various cabinets on the Coudé Rotator are monitored to ensure they are closed during Coudé Rotator movement.
