Introduction to the Quaternary Pump
Early Maintenance Feedback (EMF)
Using the EMF Counters
The user-settable EMF limits for the EMF counters enable the early
maintenance feedback to be adapted to specific user requirements. The wear
of pump components is dependent on the analytical conditions, therefore,
the definition of the maximum limits need to be determined based on the
specific operating conditions of the instrument.
Setting the EMF Limits
The setting of the EMF limits must be optimized over one or two
maintenance cycles. Initially, no EMF limit should be set. When performance
indicates maintenance is necessary, take note of the values displayed by
pump liquimeter and seal wear counters. Enter these values (or values
slightly less than the displayed values) as EMF limits, and then reset the EMF
counters to zero. The next time the EMF counters exceed the new EMF
limits, the EMF flag will be displayed, providing a reminder that maintenance
needs to be scheduled.
