MGS-550 Fixed Gas DetectorP/N: 1100-1000 Version 1 294.4 Parameters4.4.1 Sensor 1 Settings (S1-xx) and Sensor 2 Settings (S2-xx) if ConnectedS1 & S2 Param Name (n=1 or 2) Description (n=1 or 2)S1-01 S2-01 Sensor n Gas Name Abbreviated Gas NameS1-02 S2-02 Sensor n UID Unique 5-digit sensor ID (serial number)S1-03 S2-03 Sensor n Low Alarmppb/ppm/%LEL/Vol%Value above which a low alarm condition occurs.Low alarm value must be less than the medium andhigh alarm values (Sn-03 < Sn-04 < Sn-05). (Seeoxygen sensor notice below.)This parameter has a fixed minimum limit that issensor–specific and not editable.S1-04 S2-04 Sensor n Medium Alarmppb/ppm/%LEL/Vol%Value above which a medium alarm conditionoccurs. Medium alarm value must be between lowand high alarm values (Sn-03 < Sn-04 < Sn-05).(See oxygen sensor notice below.)S1-05 S2-05 Sensor n High Alarmppb/ppm/%LEL/Vol%Value above which a high alarm condition occurs.High alarm value must be greater than low andmedium alarm values (Sn-03 < Sn-04 < Sn-05).(See oxygen sensor notice below.)S1-06 S2-06 Sensor n Low AlarmBehavior0 = Disabled1 = Non-latching, not acknowledgeable2 = Non-latching, acknowledgeable3 = Latching, not acknowledgeable4 = Latching, acknowledgeableS1-07 S2-07 Sensor n Medium AlarmBehaviorS1-08 S2-08 Sensor n High AlarmBehaviorS1-09 S2-09 Sensor n Type Code 4-digit sensor code (read-only)S1-10 S2-10 Sensor n Units Read-Only.

Sensor n full-scale units: ppb or ppmor Vol% or %LEL.S1-12 S2-12 Sensor n Test Flag When set to 1, this flag indicates that a calibration isrecommended. This flag can be reset to 00 byeither successfully completing a span adjustment(see section 5.2.4: Span Adjustment on page 38) orby changing the value manually.0 = Sensor OK1 = Sensor in operation for >6 months withoutcalibration. Recalibration recommended.The following parameters are sensor dependent.• Low alarm limit (S1-03 and S2-03)• High alarm limit (S1-05 and S2-05)• Unit of measurement (S1-10 and S2-10)• Factory default values for the alarm thresholdswww. .com information@itm.com1.800.561.8187
