6 Troubleshooting and Diagnostics

Overview of the Module’s Indicators and Test Functions

Status Indicators

The module is provided with two status indicators which indicate the

operational state (prerun, run, and error states) of the module. The status

indicators provide a quick visual check of the operation of the module.

Error Messages

In the event of an electronic, mechanical or hydraulic failure, the module

generates an error message in the user interface. 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 chapter Error

Information).

Test Functions

A series of test functions are available for troubleshooting and operational

verification after exchanging internal components (see Tests and

Calibrations).

System Pressure Test

The System 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.
