3.0 REQUIREMENTS.

The following Materials and Services are required to upgrade Government-owned Schenck Balancing Machines (Models H30BU & HM30BU) in Building 797 with modern Computer Aided Balancing (CAB) Instrumentation. The specified system is the CAB 925 instrumentation.

3.1 The vendor shall provide and install, on-site, the required components to upgrade the existing Government-owned Schenck Balancing Machine to modern CAB instrumentation.

3.1.1 The CAB upgrade package shall include all electronics, computer(s) and balancing software required to operate the balancing machine.

The CAB software shall include Society of Automotive Engineers (SAE) Test Software for the specific machine class, Index Balancing for any set-up incorporating balancing tooling, Single Compensation to nullify residual dynamic imbalance, Key Compensation to electronically compensate for imbalances caused by missing keys, and Averaging Over- Time Features.

3.1.2 The CAB upgrade package shall include two (2) replacement programmable drive controllers. Controllers shall be the modern equivalent of the existing General Electric DV-300 and currently supported by the Original Equipment Manufacturer.

3.1.3 The CAB upgrade package shall simultaneously display vector meters (polar coordinates) and digital readouts for assessment of the test object's unbalance measurement.

3.1.4 The CAB upgrade package shall include automatic sensitivity selection so that the proper balancing sensitivity is selected by the CAB unit without additional input of balancing parameters by the operator.

3.1.5 The CAB operator interface provided by this upgrade shall use three screens for operation of the balancing machine.

Set-up screen for entry of test parameters and test object specifications.

Tolerance screen to determine when the test object is within the desired tolerance parameters.

A readout screen to compare the results of the current balancing run with the previous balancing run.

3.1.6 The windows shall automatically upload when turning on the system. They shall be programmed and auto arranged o allow users to easily see each screen on the computer.

3.1.7 The CAB upgrade package shall include an electronic protractor feature, which signals to the operator that the angle of unbalance on the test object is located at top dead center, or a pre-established reference angle set by the operator.

3.1.8 The CAB upgrade package shall include a printer documentation system capable of printing test graphics, rotor set-up data, and the amount of unbalance and angles of unbalance for both correction planes during a balancing test.

LaserJet, duty cycle of 1000 pages or similar printer.

3.1.9 The CAB upgrade package shall include an ISO tolerance feature, which automatically calculates test tolerance requirements based on ISO 1940/1 quality grades, test object weight, service speed, and location of the test object's center of gravity.

3.1.10 The CAB upgrade package shall accommodate balancing tests at rotational speeds of 100-

5000 RPM.

3.1.11 All electrical components including motors, starters, relays, switches, and wiring shall conform to and be located in accordance with the applicable NFPA, NEMA, and ANSI standards for the intended application.

3.2 Additional On-Site Services

3.2.1 For each CAB 925, after commissioning, the vendor shall provide up to two (2) working days of instrumentation and operator training.

Commissioning services shall consist of the following: inspection of the instrumentation installation to ensure that the system has been installed properly, ensuring proper power connection, check for compliance of OSHA safety requirements, and a confidence test of the balancing machine and CAB instrumentation functionality with suitable work pieces provided by the Government.

The training shall be for four (4) operators. Training shall be performed at the Government facility and shall not be less than two (2) consecutive eight (8) hour workdays, between 7:00 am and 3:30 pm excluding weekends and federal holidays.

The course shall utilize the manuals provided under this contract, and shall include both classroom (if required) and hands on portions. All printed training aids shall be supplied for the course, be in the English language, and become the property of the Government. Additionally, the training shall consist of the following:

• overview of instrumentation set-up.

• overview of CAB instrumentation and related software features

Operations & Maintenance training shall consist of the following: overview of the operator manual, overview of instrumentation set-up, overview of CAB instrumentation and related software features, and recommended preventative maintenance practices.

3.2.2 The vendor shall complete all work required within fourteen (14) working days from start for the installation of the programmable drive controllers.

3.3 The contractor shall provide two (2) hard copy and one (1) electronic (PDF) copy of the Operations & Maintenance manual for each unit of upgraded equipment (CDRL A001).

3.4 Quality assurance shall consist of the industry best practices for commissioning of a balancing machine, including but not limited to all actions defined in 3.2.1.1.

3.5 Uninstall and removal of existing system

3.5.1 Uninstall the CAB 690H platform and General Electric DV-300 Programmable Drive controller.

3.5.2 The contractor shall be responsible to disconnect and disassemble the equipment and place them outside of the building with protective covering. The Government shall dispose of the equipment removed.

3.6 Installation

3.6.1 Installation shall include any attachments or new infrastructure required to integrate new CAB system with existing hardware.

Attachments include all electrical and mechanical additions/modifications needed for the new CAB operations

4.0 PERIOD OF PERFORMANCE
