M-5 Operation And Maintenance Manual ▪ Signal Range is the assignment of the 4 to 20 mA signal. Default assignment of 4 mA is zero concentration. The default setting for 20 mA varies with the gas type. The Signal range is fully adjustable within the limits imposed by the Display Range. Both the 4 mA level and the 20 mA level can be reassigned through the menu system. -

- Page 12 M-5 Operation And Maintenance Manual This feature allows adjustment of the 20 milliamp point to different gas concentrations. The display will always read as low as the maximum for that gas but the concentration corresponding to 20 milliamps changes. Note that the display maximum is not affected by this adjustment.

M-5 Operation And Maintenance Manual removing the old sensor. Sensor location is shown below. There are 2 locations based upon the sensor type. 1. CO Sensor Replacement The CO sensor is plugged into a female socket, and a drop of glue applied to the sensor to make sure the sensor does not fall out during shipping. - Page 18 M-5 Operation And Maintenance Manual The unit will automatically restart and continue normal operation if the fault occurred due to a temporary intrusion (e.g.: Radio frequency interference or water condensation formed due to fast temperature change). A fault shown repeatedly indicates malfunction of the unit. In such cases the fault code should be recorded and the unit returned for repair.
