Overview
As the power market has shifted from coal to gas plants, so have the power plant needs
changed from base load to peaker plant operations. This shift has caused a need for analyzers
to work from a continuous mode to an on-demand mode. Thermo Scientific identified this
requirement as an enhancement feature and has introduced this into the new Orion 2230 Silica
Analyzer.
The Orion 2230 is equipped with two modes of operations:
1- AUTO RESTART mode (default)
2- MANUAL mode
The mode of operation may be selected by the user by pressing the MENU key:
SET UP ➔ + (pg2) ➔ ANALYSIS PARAMETERS ➔ MODE
AUTO RESTART allows automatic restart of the sample measurement mode (same as
pressing the RUN key) after 30 minutes wait/idle time. The unit will resume running analyses
per the selected frequency (default 15 min).
In MANUAL mode, the system will wait for the operator command via keypad (RUN key) or
external control to start/resume analyses per the selected measurement frequency. If no
command is received, the system will switch to stand-by after 1 hour wait/idle time.
