1.0OVERVIEW

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 pro- grammed 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.

1.1Hardware

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 oper- ating 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 E-

 

STOP switch has been pushed (latched) and pulled out (unlatched).

1.2Software

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.

E8-CE, E4H-CE specifications

The GE E4H-CE and E8-CE represent the latest advancements in electric locomotives, showcasing GE's commitment to innovation and efficiency in rail transport. These models are designed specifically for freight applications, delivering a powerful combination of performance, reliability, and environmental sustainability.

One of the standout features of the E4H-CE is its robust traction system, which is engineered for maximum efficiency. The locomotive boasts a high horsepower rating, allowing it to handle heavy loads with relative ease. Its lightweight design contributes to reduced power consumption, making it an economical choice for rail operators. The E8-CE takes this a notch higher, incorporating advanced traction technologies that enable optimal torque distribution across all wheels, enhancing overall traction and stability under various load conditions.

Both models are equipped with GE's state-of-the-art digital control systems, which foster seamless communication between various locomotive systems. This integration allows for improved diagnostic capabilities, ensuring that operators can monitor equipment health in real-time, leading to reduced downtime and increased efficiency. The user-friendly interface provides essential data at a glance, empowering engineers to make informed operational decisions swiftly.

In terms of design, the E4H-CE and E8-CE feature aerodynamically optimized shapes that minimize drag. This not only enhances fuel efficiency but also contributes to reduced noise pollution, making them compliant with stringent environmental regulations. The trains are built with durable materials designed to withstand the rigors of freight transport, ensuring longevity and lower maintenance costs.

Additionally, both locomotive models offer various options for upgradable technology, including hybrid systems that combine traditional electric propulsion with battery assistance. This hybrid technology is part of GE's broader initiative toward sustainable transport solutions. Furthermore, the E8-CE is equipped with regenerative braking systems that recover energy during braking, reintroducing it back into the grid or using it for auxiliary systems, thereby enhancing overall energy efficiency.

In conclusion, the GE E4H-CE and E8-CE locomotives exemplify cutting-edge technology with an emphasis on performance, efficiency, and environmental stewardship. Their advanced features make them suitable for modern freight operations, promising cost-effectiveness and reliability while paving the way for a more sustainable future in rail transport.
