No fibre optic communications and Beam Control Unit has no power on the AutoSpec - WKB48735

SYMPTOMS

• MassLynx very slow to boot. - Several minutes.
• Error message shown when MassLynx has eventually started.
• Error processing file C:\MassLynx\AutospecVXWORKS\ASPECVAC.INI/error reading line 0x0 /rioPropertyGetInstanceID:Null handle/ 
  • 
• No Instrument control.

ENVIRONMENT

• AutoSpec Premier (P)
• AutoSpec Ultima (M)
• MassLynx

CAUSE

Fault in instrument internal Fibre Optic Loop communications.  Beam Control Unit off with no power.

FIX or WORKAROUND

1. Close MassLynx.
2. Lock the system into "Standby" using the front panel Instrument Status Switch.
3. Reboot the EPC and monitor boot progress by typing " PING EPC -t" into the Start/Run box.
   • A command Box will open and show ping responses during the boot.
   • 
4. Wait up to 2 minutes until many responses show less than 1ms to reply. - Indicates boot sequence has completed.
5. Close the Ping window.
6. Run rioMainMenu to check the status of the instrument internal loop communications:
   • Enter "TELNET EPC" into the Start/Run box.
   • Telnet will open with a "->" prompt.
   • Enter "rmm" followed by return into the Telnet window. - All characters should be entered in lower case.
   • The following will be displayed:

   •  The above list of 3 "Subsystems" confirms a failure in the internal loop communications path.
   • Enter "999" two or three times until the "->" is displayed.
   • Close the Telnet Window 

7. Remove the panel to expose the Beam Control Unit.  This is located at the front of the instrument underneath the Magnet. - See the location diagram in additional information.

8. Check that the "Standby" power switch on the front of the Beam Control Unit is illuminated.
9. If no illumination is seen check FS1.
   • Power off the Beam Control Unit "Standby" Power switch.  Set it to position "0".
   • Power off the "Bench" Circuit Breaker located on the Mains Distribution Unit located at the front of the instrument underneath the GC
     • See the location diagram in additional information.
   • Remove FS1 with the aid of a small coin or large slotted screwdriver.
   • Check the fuse for visible burning or with the aid of a Digital Volt Meter.
     • Open Circuit, infinite or very high resistance, would indicate a failed fuse. 
   • Replace the fuse with the identical item. PN 1340141-S FUSE GLASS 1.25A 20MM A/S (10/PACK)
   • Power on the "Bench" Circuit Breaker
   • Set the Beam Control Unit "Standby" Switch to the On, "1" position.
   • Check for illumination in the "Standby" switch. 
     • Note the "Operate" Switch will not show any illumination
     • Check power cable for 240V AC. If no power check the power strip located underneath Magnet that 240 V AC is being supplied to it
     • If Yes check fuse within strip
     • If No check FS3 in AC Distribution unit.
10. Restart the EPC and as above monitor the boot progress via "PIN EPC -t" closing the window when complete.
11. Run rioMainMenu to recheck the status of the instrument internal loop communications:
    • Enter "TELNET EPC" into the Start/Run box.
    • Telnet will open with a "->" prompt.
    • Enter "rmm" followed by return into the Telnet window. - All characters should be entered in lower case.
    • The following will be displayed:

    • Enter "999" two or three times until the "->" is displayed.
    • Close the Telnet Window
12. Start MassLynx which will boot normally.
13. Refit any removed instrument panels.
14. Check in the tuning window the Solenoid Slit Settings if applicable. - These may have set to default values.  Re-enter the values from a saved copy.
15. Restart the Magnet.
16. The system will now be fully operational.  The Instrument Status switch may be set to Operate to allow the instrument to be set into operate.
