Basic System Troubleshooting
This chapter describes the pump's built in troubleshooting and test functions:
Status Indicators
The nano pump is provided with two status indicators which indicate the
operational state (prerun, run, and error states) of the nano pump. The status
indicators provide a quick visual check of the operation of the nano pump
("Status Indicators"
Error Messages
In the event of an electronic, mechanical or hydraulic failure, the nano 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
Micro Pressure Test
This is a fast test to verify the tightness of a micro system, where the pump is
operating in the micro mode and no manual purge valve is installed. The pump
is operating in the pressure control mode at 380 bar for several minutes. The
remaining flow in the column flow path between the EMPV and the blank nut
is measured. ("Testing your Nano Pump"
