A&D Technology Inc.

Plan Overview

Routine preventive maintenance provides extended life and operation for your equipment, and helps to guard against system downtime.  With this plan, a comprehensive inspection will be performed, and a detailed report will be presented to address the major and non-critical issues, and solutions will be presented to fix any situation as quickly as possible.

Features

  • Motor mechanical inspection and check out  (More Info)
  • Drive electrical inspection and check out (More Info)
  • Detailed report with inspection results
  • Five (5) hours of Help Desk support
  • Unlimited email support
  • Discounts on software, spare parts, on-site labor and training courses


Plan Details

Standard preventive maintenance services as described below will be performed during a mutually-agreed-upon time by experienced, factory-trained A&D employees in order to minimize your cell downtime.  If any additional work is needed once inspections are complete, all on-site service work on the dynamometers will be billed at 10% off the standard labor rates as defined in this plan.

Spare Parts

A 10% discount will be applied to any parts required to maintain your dynamometer system.  A&D will make recommendations on parts or additional repairs needed during the maintenance visit.

Discount Services

 This support plan includes a 10% discount on software, in-house training at A&D, spare parts and on-site labor rates.

Coverage
Hours

 Support and Help Desk services will be provided from 8:00 am to 5:00 pm Monday through Friday, excluding A&D-observed holidays.

Travel Expenses

 Travel and living expenses will be invoiced at cost.


Optional Services

Vibration
  • Take vibration readings from several bearing points (front, back and center bearing block if applicable) on dynamometer motor to determine bearing wear, motor concerns and possible alignment issues
  • Provide detailed reports of vibration data from bearing points at different speeds
  • Provide recommendations for any corrective actions deemed necessary

Harmonics
  • Take harmonic readings from several potential sources in dynamometer test cell to determine potential sources of noise

Shaft Alignment
  • Check the dynamometer shaft alignment with the test components to determine potential problem areas
  • Take appropriate actions to correct any areas of concern

Software Tune Up
  • Have a trained technician go through the data acquisition and control system for the entire test cell
  • Provide recommendations for any corrective actions deemed necessary, such as tuning loops of calibration
  • Take appropriate action to correct any areas of concern

Documentation Updates
  •  Have a trained technician go through the documentation for the data acquisition and control system for the entire test cell and verify that the wire terminations and labels are in place and reflected in the print set
