Troubleshooting and Test

Functions

This chapter describes the instrument’s built in troubleshooting and test functions.

Status Indicators

The quaternary pump is provided with two status indicators which indicate the operational state (prerun, run, and error states) of the quaternary pump. The status indicators provide a quick visual check of the operation of the quaternary pump (see “Status Indicators” on page 45).

Error Messages

In the event of an electronic, mechanical or hydraulic failure, the quaternary pump generates an error message in the user interface. The following pages describe the meaning of the error messages. For each message, a short description of the failure, a list of probable causes of the problem, and a list of suggested actions to fix the problem are provided (see “Error Messages” on page 47).

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 “Pressure Test” on page 82).

Leak Test

The leak test is a diagnostic test designed to determine the pressure tightness of the quaternary pump. When a problem with the quaternary pump is suspected, use this test to help troubleshoot the quaternary pump and its pumping performance. The following sections describe these functions in detail (see “Leak Test” on page 88).
