Overview of the Pump’s Indicators and Test Functions
This chapter describes the instrument’s built in troubleshooting and test
functions.
Status Indicators
The preparative pump is provided with two status indicators which indicate
the operational state (prerun, run, and error states) of the preparative pump.
The lower left indicates the power supply status, the upper right indicates the
preparative pump status.The status indicators provide a quick visual check of
the operation of the preparative pump (see “Status Indicators” on page 72).
Error Messages
In the event of an electronic, mechanical or hydraulic failure, the preparative
pump generates an error message in the user interface. For details on error
messages and error handling, please refer to the Agilent Lab Monitor &
Diagnostic Software.
Pressure Test
The pressure test is a quick test designed to determine the pressure tightness
of the system. After exchanging flow path components (e.g., pump seals or
injection seal), use this test to verify the system is pressure tight up to 400 bar
(see “Prep Pump Pressure Test Description” on page 94).
Leak Test
The leak test is a diagnostic test designed to determine the pressure tightness
of the preparative pump. When a problem with the preparative pump is
suspected, use this test to help troubleshoot the preparative pump and its
pumping performance (see “Prep Pump Leak Test Description” on page 98).
