Error Handling (continued)
Incident Corrective Action
Y-Movement: 1. Check visually the elastic sheet metal holding
the Y-Motor Drive. The Y-Nut Bore must be
rectangular to the Channel (no signs of
bending). A bent sheet metal indicates too much
friction between Y-Spindle and nut which may
lead to steps lost.
2. The Y-Motor metal plate nose must fit into the
groove. If not, too much friction between Y-
Spindle and Nut which may lead to step lost.
3. Check if the Belt is still in place.
4. Check all the cable connections of the channel,
focussing on y-motor cable.
5. Perform an Auto-adjustment and check visually
the linearity of all Channels.
Turning the Y-Motor by hand, no hardware-
based friction is recognized e.g. signs of
damaged bearing, broken parts inside etc.
(except the electromechanical resistant).
If no improvement, check Y-Spindle for possible
damage and replace Channel. Decide if Y-
Spindle should be replaced as well
Pipetting Head loss of seal 1. Ensure Stop Disk has no scratches - the
smallest scratches may lead to an loss of seal. If
there are scratches, replace Stop Disk.
2. Check CO-RE O-Ring for signs of wear and
tear. Black abrasions may be found around O-
Ring and Stop disk - if so replace O-Ring.
