305.2.7 Replacing ComponentsReplacing the Turbidity Meter1) Turn off the inlet and outlet water to the flow cell and the power to the analyzer.2) Open the door of the control module.3) Remove the 5 wires from the bottom of the Turbidity input module4) Remove the meter from the flow cell by unscrewing the cap and pulling gently5) Install the new meter in the flow cell6) Route the wires back to the turbidity module and reconnect the 5 wires following the color coding onthe module.7) Restart the flow and turn the power on8) Confirm that proper operation has been restoredReplacing Turbidity Input ModuleDisconnect the power supply to the unit before opening the control unit.1) Disconnect the flat cable plug from the card.2) Disconnect all terminal blocks3) Unscrew the four (4) mounting screws.4) Put in the new card and tighten the 4 mounting screws.5) Connect the flat cable plug to the card6) Reconnect the terminal blocks5.3 Conductivity Measurements5.3.1 InstallationIf the WaterGuard system was ordered with the Conductivity pre-installed some of these steps will havebeen completed in the factory.Supplied Components• Conductivity 4-20 input Module (electronics card)• 150mm Flat Cable (ribbon cable)• Conductivity meter• Conductivity flow cellCaution: Prior to opening the analyzer or installing any electrical components, turn off all power suppliesto the analyzer1) Attach the module to the inside of the control panel door below the control panel module using the 4supplied screws.2) Attach the ribbon cable from the conductivity module to any open connector on the I/O module.3) Mount the conductivity flow cell and meter on a solid wall or surface using appropriate hardware (notsupplied). Make sure that the distance is less than 15m (45 feet) from the WaterGuard analyzer.4) Connect a water supply of no greater than 2 bar (30 psi) to the inlet fitting using 6mm tubing. It maybe a new separate water supply or a line tapped from the main analyzer water supply before the pre-filter. Larger tubing may be used if the fitting is replaced to accept the new tubing.5) Connect a 6mm water outline line to the outlet fitting and connect to:a. The main water system at least 5 psi (0.3 bar) lower than the inlet water supply orb. The pre-filter of the WaterGuard analyzer. |
