1.0 OVERVIEW

The GE Osmonics E4H-CE and E8-CE water treatment systems consist of modular equipment that
is designed to work together with the reverse osmosis (RO) machine at the heart of the system.
The Programmable Logic Controller (PLC) and Operator Interface Terminal (OIT) are pro­grammed to control a complete, integrated system. 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-ST

OP: 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-ST

OP RESET: A momentary push-button switch that will restore power after the E-

STOP 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.

The RO machine is controlled using the Operation Screen. 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 the MACHINE STATUS Screen, described
later (Section 2.4).

The UTILITIES Button takes the user to the UTILITIES Screen, described later
(Section 2.5).

The ALARM RESET Button is used to clear any alarm conditions, such as low inlet pres­sure, high permeate pressure, or motor overload. This button needs to be pressed before
the RO machine will operate. The ALARM RESET Button on the Control Enclosure may
need to be pressed as well.

The SYSTEM message, located under the Control Buttons, shows the user the current sta­tus of the machine. During shutdown, this message will display reason for shutdown.
