Analyzer Operation
Thermo Scientific Orion 2117HL High Level Chloride Analyzer User Guide
ALRM
Set up to three alarms – high, low and an error signaling contact:
• Relays 1 and 2 (rLY1, rLY2) are normally open dry contacts used to set
high and low alarms for measurement values
• rLY1 and rLY2 options – OFF, HI, LO
• Relay 3 (rLY3) is normally a closed contact that can be dedicated to
errors (will close if power to analyzer is lost), this alarm is influenced by
calibration, errors and offline or hold status
• rLY3 options – OFF, CAL, HOLD, Err
• Default setting for all alarms – OFF
mAMP
Set the two analog current outputs (SOUt and tOUt):
• Scroll between 4-20 mA or 0-20 mA current signals
• The outputs share a common return, but are isolated from the main
circuitry of the analyzer
• Default output current – 4-20 mA
• Scroll between logarithmic (LOg) and linear (LIn) scale for SOUt
• Set the low and high limits for the sensor output (SOUt)
• Default – 1.0 ppb (low) and 100 ppb (high)
• Set the low and high limits for the temperature output (tOUt)
• Default – 5.0 °C (low) and 45.0 °C (high)
mADJ Set the mA offset adjustment value for the sensor (SOUt) and temperature
(tOUt) outputs:
• Select the sensor (SOUt) or temperature (tOUt) output
• Scroll the numeric offset value and positive or negative offset value
• Default mA offset – 00.0 mA
