Verify the firmware setup. Refer to Section III.D.
Calibration error:
Error Code 1:
Error Code 1 indicates a Platform calibration error. (A picture of the instrument platform is shown
in Section II, Figure C, page 9.)
• Verify that there are no obstructions in the slide channels, in the rear, or in front of the platform
that prevent it from moving back and foward freely.
• If in LEV mode, ensure the cartridges are seated completely in the LEV Cartridge Rack, and
that the rack is seated onto the platform properly. Refer to Figure 4B (page 21) for a diagram.
• Turn the instrument off, wait a few seconds, then turn the instrument back on. If the calibration
error persists, please contact Promega or your local Promega representative for service.
Calibration error:
Error Code 2:
Error code 2 indicates a Plunger Bar calibration error (A picture of the plunger bar is shown in
Section II, Figures A and B, page 9.)
• Verify that there are no solid particulates (e.g., bone, swab tips, large particulates, etc.) inside
Well #1 of the cartridge. Solid particulates which are not easily macerated, may obstruct the
plunger from moving freely to the bottom of Well #1 during processing.
• Verify that the plastic reagent cartridge is seated properly. Refer to Figure 4, Panels A and B
(page 21) for a diagram.
If in LEV mode
, ensure the cartridges are seated completely in the
LEV Cartridge Rack, and that the rack is properly seated on the platform.
If in SEV mode
,
ensure the cartridges are seated properly onto the platform.
• If the error occurs during plunger loading, ensure the hardware configuration matches the
firmware settings. Select “No” after the “Continue?” prompt on the LCD screen (see Section
IV.B, page 20).
• Verify that the shipping anchors have been adjusted properly. Refer to Section III.B.
• Turn the instrument off, wait a few seconds, then turn the instrument back on. If the
calibration error persists, please contact Promega or your local Promega representative for
service.
