Every time the Analyzer/Controller is powered up the unit performs a “warm reset”. During a warm reset, alarms are not cleared, and outputs are maintained at their last value prior to the loss of power or initiation of the warm reset. A warm reset has no effect on configuration or calibration values.

In addition to this warm reset, a “cold reset” function is available to return ALL configuration values to the factory settings shown in Table 5-10. During a cold reset some I/O setup values will also be changed. In addition, the cal factor will be set to match the default cell constant, and the calibration trim or TDS ( total dissolved solids) conversion factor will be removed, eliminating any changes made using the calibration menu (see Section 8). All alarms will be cleared. Analog outputs will go to zero momentarily, then go to the factory default values. A cold reset can be initiated using a maintenance menu function as described in Section 10. It will also be initiated during I/O setup if the measurement type, relay activation, display resolution, cell constant, or an analog or discrete I/O assignment is changed.
