Product overview PROGNOSYS (Prognosis System) is a software package used to monitor and show the reliability of measurement values and to identify pending maintenance tasks. This software is available for sc sensors. The sc1000 controller operates and configures the software. The controller display will show horizontal bars as a measurement value indicator and as a service indicator for the remaining time until the next maintenance task.
Figure 1 Keypad description 1 Enter: Saves the setting and exits the current screen to the CONFIGURE menu 4 Delete: Removes a sensor from the selection 2 Cancel: Exits the current screen to the CONFIGURE menu without saving the setting 5 UP and DOWN arrows: Moves the sensors up or down the list 3 Add: Adds a new sensor to the selection Startup Add a sensor Note: PROGNOSYS is not available for all sensors. Only newer sensor models can use the PROGNOSYS function.
Figure 2 Add sensors 1 Select sensor 4 Add 2 Accept 5 Select additional sensor 3 Sensor list Sort the sensors (RTC modules only) The sensor sequence is programmed in the RTC module for the measurement values. To sort the sensors in the order specified for the RTC module, move the selected sensor with the UP and DOWN arrows. Refer to Figure 3.
Figure 3 Sort the sensors 1 Select sensor 2 UP and DOWN arrows Delete a sensor from the list To delete a selected sensor from the list, push Delete. Refer to Figure 4. Figure 4 Delete a sensor 1 Select sensor 3 Delete the sensor 2 Go back without changes Operation PROGNOSYS indicator bars If PROGNOSYS is installed, two additional horizontal bars show in the top right-hand corner of the measurement screen. The top bar is the measurement value indicator. The bottom bar is the service indicator.
Table 1 Color definitions Color Definition Green The sensor is in operation with no warnings, errors or reminders. Yellow The sensor is in operation with active warnings or reminders. The measurement indicator (top bar) shows a possible measurement value deviation, but the value is still within the permitted tolerance. The service indicator (bottom bar) shows an upcoming maintenance task which includes a countdown period. Set the countdown period between 7 and 14 days.
Figure 6 Display overview for four sensors 1 Sensor 1 3 Sensor 3 2 Sensor 2 4 Sensor 4 Measurement value indicator If the sensor condition changes, the measurement value indicator changes. A deterioration of the measurement value indicator level in the top bar can change the color in the bottom service bar. Pending maintenance tasks do not have an immediate effect on the measurement value indicator (e.g., to replace the reagents).
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.
Configure the sensor Use the PROGNOSYS menu to monitor specific settings or to change the blink mode. 1. Push MAIN MENU>RTC MODULES/PROGNOSYS>PROGNOSYS. 2. Select the applicable sensor. 3. Select an option. Option Description MEAS. INDICATOR Shows the measurement indicator bar in %. DETAILS Shows the message list for the measurement indicator. Example: R
Message Possible cause Pump piston replacement If 0 day is shown, the time for the pump piston is expired. Air filters clean The maintenance for the air filter is necessary. Reagent days Shows the days that remain to replace the reagent. clean Solu days Shows the days that remain to replace the cleaning solution. Standards days (AMTAX sc only) Shows the days that remain to replace the calibration standard.
NITRATAX plus sc Message Sensor, Application check R
Message1 Possible cause Solution RFID-Data not valid The RFID calibration data for the cartridge could not be read. Enter the sensor code for the temporary sensor operation manually, then replace the cartridge. Reference potential uncertain The data supplied by the reference system for the cartridge is not reliable. Examine the measurement values and if necessary, replace the cartridge.
Message1 Possible cause Solution NH4 electrode damaged The NH4 electrode is damaged. NO3 electrode damaged The NO3 electrode is damaged. K+ electrode damaged The K+ electrode is damaged. CL- electrode damaged The Cl- electrode is damaged. NH4 MX2: high Temp. diff. P1 P2 The temperature difference between the two correction points of a matrix correction (MX2) or value correction (VC2) for NH4 is more than 7.5 °C (45.5 °F).
Message Check wiper function Wiper position unknown Possible cause The wiper is mechanically blocked. The measurement window is not clean anymore. No sample is pulled in the instrument. The wiper is possibly in front of the window. Solution • Examine and clean the measurement window fully. • Complete a wiper test and do a stop position test. • Contact technical support. Replace wiper motor The counter for wiper motor is expired. Contact technical support to replace the wiper motor.
Message Possible cause Solution Red amplitude low The sensor cap surface is damaged or worn. The reflection is not correct. Examine the sensor cap for damage or wear. Replace the sensor cap. Red amplitude high The sensor cap surface is damaged or worn. The sensor is received too much ambient light. Blue amplitude low The sensor cap surface is damaged or worn. The reflection is not correct. Blue amplitude high The sensor cap surface is damaged or worn.
