A water purification system may consist of the following modular equipment: · Media Filter(s) · Chemical Injection System · Clean-In-Place (CIP) System · Permeate Storage Tank Your system may or may not contain all of the modular equipment listed above. To accommodate the variations possible, the control system is designed to allow the user to operate with any of the components list above. 1.1 Hardware A SIEMENS S7-222 PLC, located in the control enclosure, controls the system. Operator interface is done with a SIEMENS TP070 OIT mounted on the enclosure door. A Hanna Instrument 983320 Conductivity Meter and a 981411 pH Meter provide display of operating conditions as well as alarm and control set points. Electrical enclosure door mounted lights and switches are as follows: POWER ON: A clear light which indicates that the control voltage is applied to the enclosure panel. E-STOP: A latching push-button switch that will interrupt power to the PLC outputs and inputs causing the system equipment to immediately shut down. In case of an emergency, using this push button will bypass the normal shutdown procedure required to safeguard the equipment. The E-STOP switch must be pulled out and the E-STOP RESET button and the alarm reset button on the OIT pushed to restore power to PLC inputs and outputs and restart the machine. The E-STOP is lit when it is engaged and the control relay is not powered. E-STOP RESET: A momentary push-button switch that will restore power after the ESTOP switch has been pushed (latched) and pulled out (unlatched). 1.2 Software The SIEMENS S7222 PLC is programmed with SIEMENS Step 7-Micro Programming Software. The SIEMENS TP070 OIT is programmed with SIEMENS STEP 7-Toolbox Programming Software. 1 1.3 Operator Interface Terminal (OIT) Screen The available screens for the PanelView are as listed: START-UP: Contact information for customer. OPERATION: Gives run options for machine, alarm, and status messages. ALARM HISTORY: Displays last five alarms conditions. STATUS: Displays last five operating conditions. UTILITIES: Adjusts contrast, screen center, and allows user to clean display. SET-UP: Allows user to clear alarm history, run time, and status. Allows user to download new program information. 2 2.0 START-UP The START-UP Screen is displayed upon start-up of the E-CE Series RO machine. This touch screen gives customer contact information. Figure 2.1 Start-Up Screen To get to the next screen, press anywhere on the screen or wait twenty (20) seconds. 3 2.1 Operation Screen The Operation Screen displays the control function for the E-CE Series RO machine.

The FILL button energizes the inlet solenoid valve allowing the RO machine to fill water. The machine will run for ten (10) minutes filling the machine. This needs to be done before the RO machine can operate. Once the machine has been filled the RO, CIP, and PURGE buttons will operate. The RO button controls the RO machine when it is in Run Mode. If the RO machine is not in Run Mode, the RO button switches the RO machine from its current condition to Run Mode. In the AUTO position the RO machine will shut down without going into Permeate Purge. The CIP button controls the RO machine when it is in CIP Mode. If the machine is not in CIP Mode, pressing this button (CIP) will switch the machine from its current mode to CIP Mode. See the Operation and Maintenance Manual (P/N 1161875) for details on running CIP. If the machine is in CIP Mode, pressing the button shuts the RO machine down. The PURGE Button controls the Permeate Purge Cycle of the RO machine. If the RO machine is not in Purge Mode, pressing this button will switch the RO machine to Permeate Purge for ten (10) minutes and then turn the machine OFF. If the RO machine is in Purge Mode, pressing this button will shut down the machine. The AUTO/HAND Button, located under the Purge Button, controls Permeate Purge operation. In the HAND position the RO machine will only go into Permeate Purge by manually pressing the Purge Button. In the AUTO position, the RO machine will go into Permeate Purge when the RO machine gets a signal from an external device, like a level switch. The ALARM Button takes the user to the ALARM HISTORY Screen, described later (Section 2.3). The INFORMATION Button takes the user to th...
