  • Page 25 Cycle time (The time the SPI-P170 will ‘wait’ between 2 measurements in seconds. Setting this at 300, means that the SPI will wait 5 minutes, before the next measurement starts. If the color valve time is set at 0, the automatic peroxide reagent dosing is activated. This means that the dosing of a shot of peroxide color will be adapted to the use of the reagent.
  • Page 26 More time means fewer measurements, but it saves more peroxide color. The SPI-P170 will temporary stop measuring and controlling as long as this menu is opened. The pumps will remain pumping at the same level as before this menu was opened.

  • Page 42 The temporarily turning off of the SPI-P170 with data preservation, is called the hot start As the unit is commissioned for a longer period of time, the battery ages. This is causing the SPI no longer retaining the clock settings. As soon as this seems to be the fact, we advise you to take steps to replace the battery.

Software (the current version of the SPI-P170 Hydrogen Peroxide software) 2. System ID (Your custom system ID of this SPI model) You can use this information if the supplier asks for this for technical assistance.
  • Page 54 Because of the discoloration, the water will get more dark, and absorb more light. When this happens, less light will fall on the receiver, resulting in less voltage. The SPI will measure this change. A measurement without peroxide color should give an internal value of around 1000. A good measurement with peroxide color added will be much lower.
  • Page 55 SPI – P 170 P E R O X I D E 16.3.2 Calibrating zero value When the zero value starts to differ a lot from the normal value of 1000, it is important to check if the cell is clean. If the cell is clean, the cell might need to be calibrated. Calibrating implies that the zero value must be set back to its default value of 1000.
