SD, RS, and BM Pumps
Operating Instructions Page 109
Error Message Remedial Action
The pump drive is still in
maintenance position. An attempt was made to start the pump while the pump is still in
maintenance position, for example, during piston replacement or
piston seal replacement. Return the pistons into the position for
normal operation (

page 138) and retry.
If the message appears during the internal maintenance procedure
(

page 99), perform an additional purge cycle (

page 54).
The rear seal leak sensor
detects drops constantly. Verify that the seal washing liquid can run properly to the waste.
Inspect the detector of the rear seal wash system for indications of
contamination. Clean the detector if necessary (

page 127).
Heavy leakage is observed on the piston seals. Inspect the piston
seals for leakage (

page 134) and replace the seals if necessary
(

page 135).
The rear seal wash system
has run out of wash solution Rear seal washing is enabled and the peristaltic pump is running, but
no liquid reaches the seal-washing detector.
Make sure the liquid reservoir contains sufficient liquid.
Initiate another Wash cycle manually. To do so, set
RearSealWashPump to Active (

page 83).
Inspect the rear seal wash tubing for indications of leakage
(

page 125 ).
Verify that the rear seal tubing is connected properly (

Fig. 4,
page 21).
The peristaltic tubing may be blocked or draws air. Replace the
tubing if necessary.
Check the tubing for permeability.
Clean the detector of the rear seal wash system (

page 127).
Make sure that the seal washing liquid is sufficiently conductive
(

page 84).
Undock err., open purge
valve (Usually, also the pump block status LED flashes red.)
The pistons are not in the appropriate position for normal operation
(for example, after piston (seal) replacement) or an error occurred
during internal maintenance (

page 99).
Open the purge valve (with an ISO-3100BM, observing the
precautions on page 90), perform the Dock Pistons command, and
close the purge valve.
Upper pressure limit
exceeded Check whether the flow path after the purge unit is blocked. Open the
purge valve. If you are operating an ISO-3100BM, observe the
precautions on page 90.
If the flow path is blocked
- The column may be contaminated. Rinse or replace the column. If
the problem occurs due to column ageing, it may be sufficient to
increase the setting for the upper pressure limit.
- The autosampler may be blocked. Find and eliminate the source for
the blockage.
