Hach-Lange PROGNOSYS - Manual (Page 12)

Example: A probe has 10 possible indicators. Three parameters show indicators of 75%, 90% and
90%. The hidden indicators have a value of 100%. The worst incident is changed to a decimal
number: 0.75. The average of the other incidents is 0.98. The overall indicator is 0.75 × 0.98 = 0.73.
The overall indicator for the example is 73%. Refer to
Table 2 .
The message list specifies the type of the maintenance task with the number of days left until the
maintenance must be completed. The example shows to replace the cleaning solution today. The
reagents should be used up in six days. Refer to
Table 3 .

Configure the general settings
Configure service messages to send emails to the manufacturer telemetry service and to a maximum
of four freely-configured email address(es). This email gives information about important changes in
the measurement indicator and about pending maintenance tasks.
In addition, the length of the "YELLOW PHASE" of the service indicator can be configured. The
yellow phase setting applies to all sensors connected to the controller that are monitored by
PROGNOSYS. The setting specifies the duration of the yellow maintenance countdown phase in
days. For maintenance tasks that are not often necessary, the user can extend the yellow phase to
operate on a self-sufficient basis.
1. Push MAIN MENU>SERVICE>PROGNOSYS.
2. Select an option.
