24 1100 Series Nano Pump Service Manual
2 Troubleshooting and Test Functions
Instrument Status Indicator
The instrument status indicator indicates one of four possible instrument
conditions:
• When the status indicator is OFF (and power switch light is on), the nano
pump is in a prerun condition, and is ready to begin an analysis.
• A green status indicator, indicates the nano pump is performing an analysis
( run mode).
• A yellow indicator indicates a not-ready condition. The nano pump is in a
not-ready state when it is waiting for a specific condition to be reached or
completed (for example, immediately after changing a setpoint), or while a
self-test procedure is running.
• An error condition is indicated when the status indicator is red . An error
condition indicates the nano pump has detected an internal problem which
affects correct operation of the instrument. Usually, an error condition
requires attention (for example, leak, defective internal components). An
error condition always interrupts the analysis.
• A flashing yellow status indicator indicates that the module is in its
resident mode . Call your local service provider for assistance upon
observing this error condition.
• A flashing red status indicator indicates a severe error during the startup
procedure of the module. Call your local service provider for assistance
upon observing this error condition.
Error Messages - Indication
Error messages are displayed in the user interface when an electronic,
mechanical, or hydraulic (flow path) failure occurs which requires attention
before the analysis can be continued (for example, repair, frit exchange or
exchange of consumables required). In the event of such a failure, the red
status indicator at the front of the module is switched on, and an entry is
written into the instrument logbook.
