|
Update 2024-09-12: C. Fisher confirms this is actually normal behaviour. The Y-axis motion is inhibited when X and Z
are in a certain configuration, which was true when the manipulator was mounted on the wall in storage position. Non-issue. A note about this has been
made in the operator manual. |

On Friday, September 6, 2024 Model 'N' remote arm #9352 was removed from the NHC right side installed position to investigate an ongoing issue
with the tong motion circuit (no motion on the remote side when handle on operator side operated).

Model N remote arm serial #9342 tong cable has been un-jammed from between pulley 3D (see picture) and casting (this is an ongoing issue with #9342 and
9352) and cable restrung and exercised to check motion. Tong system is now functional but exhibits excessive slack. Next step will be to check tension
of the elevation/twist cables and adjust the pulley block if required (this pulley block houses both the elevation twist cable pulleys and the tong cable |

On March 27 remote end 9342 was installed on the west position (right hand as viewed by operator) and arm 9764 removed and moved to anteroom.
Previous to this installation, arm 9342 received tensioning of the elevation twist pulley block and tightening of the tong cable opening via the
tong cable drum. Tong opening was reduced to roughly 2" to achieve tension in the tong cable such that slack upon release of the system was reduced |

Tong cable on remote arm 9**4 has be relocated onto its pulleys and tong opening adjusted at the tong cable drum by changing the position of the tong
cable screws by two positions (tightened/closed) such that the air tool will fit in the tong and some of the slack in the tong system has been taking up.
An attempt was made to also adjust the elevation twist pulley block which would also aid in taking up slack in the tong system however, the elevation |

Remote end 9352 replaced with end 9764 due to signs of an issue with the tong cable (tong opening excessively large and slack in cable on one side).
Upon replacement tong opening on 9764 also opened larger then the remote end was set to. Everything is operational but this phenomenon indicates the handle
cable system on operator side must be where the excess is coming for. This is further indicted but the position of the locking screw on the handle cable |
