Operating Instructions
Remedial Action
The left valve did not reach the specified position within a certain
time. There may be no valve installed or the valve is not configured
properly.
Check and change the valve type in Chromeleon or on the oven
display (→ page 50 or page 106) if required and switch the valve
again. Contact Service if the message appears again.
The left valve did not reach the specified position. The valve may not
be configured correctly or may be blocked.
Check and change the valve type in Chromeleon or on the oven
display (→ page 50 or page 106) if required, verify that the valve is
not blocked, and switch the valve again.
Contact Service if the message appears again.
When being switched, the left valve recognized that the number of
ports configured for the valve does not match the actual number of
valve ports. Check and change the setting as necessary (→ page 79).
Drive initialization failed for the left equilibration piston of the NC
pump.
Turn the module off and on again by pressing the power switch on
the rear of the module. Contact Service if the message appears again.
Drive initialization failed for the left working piston of the NC pump.
Turn the module off and on again by pressing the power switch on
the rear of the module. Contact Service if the message appears again.
The motor current is too high when the loading pump is running.
The flow path before the transducer for the system pressure may be
blocked. Make sure that neither the capillary from the working
cylinder to the equilibration cylinder nor the capillary to the purge
unit is blocked. Replace the capillaries if necessary.
Verify that the check valve cartridges of the loading pump are
installed in the direction of flow (→ page 182).
Inspect the purge valve of the loading pump for indications of
blockage. Replace the purge valve screw if necessary (→ page 210).
The motor may be defective. Contact Service.
An attempt was made to perform an Abort command. However, no
action or command was being executed that can be aborted.
The drive of the NC pump could not be initialized within 30 seconds.
Turn the module off and on again by pressing the power switch on
the rear of the module.
The message is for information only, indicating that a ProFlow flow
meter has been installed.
