Troubleshooting and Test Functions

Power Supply Indicator

Power Supply Indicator
The power supply indicator is integrated into the main power switch. When
the indicator is illuminated (green) the power is ON.
When the indicator is off, the module is turned OFF. Otherwhise check power
connections, availability of power or check functioning of the power supply.

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 binary
pump is in a prerun condition, and is ready to begin an analysis.
• A green status indicator, indicates the binary pump is performing an
analysis (run mode).
• A yellow indicator indicates a not-ready condition. The binary 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 binary 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.
