Planned Maintenance (PM) schedule overview

Planned Maintenance (PM) tasks are developed from design requirement and operations/use assumptions to provide for the minimum required maintenance that maintains specified equipment design performance, high image quality, and safety. GE Healthcare (GEHC) advanced service methods are developed to maximize efficiency and use system access time as productively as possible, as described in the lifecycle maintenance statement.

The advanced service methods in this service manual introduce three important concepts tied to design output operation and use assessment of equipment:
  1. The Warranty IB PM Schedule Concept: The Warranty PM Service requirement is different from the lifecycle Out of Warranty (IBOW) PM Service requirement due to manufacturing tests/checks, and installation PM checks, done during the install process, and the newness of the equipment and parts during the first 12 months after install.
  2. The Remote (Digital) PM Schedule Option: The use of remote, digital performance monitoring in place of on-site performance monitoring in PM tasks and schedules. If the performance tasks are observed digitally, and passed remotely with an approved digital method, then the on-site performance checks are not required for those tasks. Refer to the Digital Remote Check Procedure in Appendix A
  3. Equipment Operation Check (EOC): EOCs are not PMs, but rather operational checks required by both customer operators and engineers to make sure of safety or equipment performance. EOCs are typically Customer Operator procedures or finalization procedures that an engineer completes if they are present on-site and have performed maintenance. In the case of MR and these products, the Magnet Rundown Unit (MRU) check that is required approximately weekly when the customer or the engineer enters the magnet room will no longer be a PM, but will become an EOC.

PM overview

GE Healthcare equipment is designed and manufactured to be of the highest quality. Likewise, the maintenance requirements in the Customer Operations Manual/User Guides and the Customer Service Manuals are designed to help maintain safe, high quality performance of your equipment for its expected life.

GE Healthcare Customer Operations Manual/User Guides and Service Manuals are designed with the intent that customers or service providers can use them when doing standard maintenance on the equipment (such as planned maintenance, which is typically time-based) without proprietary service tools or methods.
Note: Alternative original equipment manufacturer planned maintenance schedules may be used, and other routine maintenance efficiencies may be attained, based on GE Healthcare’s (or its approved partners’) use of proprietary service tools and methods, including data analysis and back office capacity. These GE Healthcare proprietary service tools and methods accomplish the prescribed and necessary routine maintenance activities identified in the Customer Operations Manual/User Guides or Customer Service Manuals.

Maintenance and repair work shall be carried out by qualified personnel, trained in maintenance and repair of this medical device in accordance with the manufacturer’s standards within the manufacturing enterprise. Customers should contact their local GE Healthcare Service Sales if they desire to have GE Healthcare complete the PMs with the Advanced (Proprietary) Service Methods and OEM trained service team.

In addition, GEHC systems have required customer, equipment operational checks that the customer should do on a periodic basis to ensure correct system operation or image quality before scanning. The details can be found in the Customer Operator Manuals.
