11 Training This chapter provides a complete, flexible training program that addresses the needs of technical personnel who service the monitor at all levels of involvement.
Introduction Introduction The training itself is self-paced. This chapter guides you through the entire service training program. All of the information you require is in this chapter, or referred to in this chapter.
Training Materials Training Materials Essential Materials The essential materials to complete this training are the following: • The C3 Service Guide (989803129451) For Philips Service Personnel, a Training Completion Form must be signed and returned to your supervisor referencing the course number "MWPMD-C3SUPP".
Support Strategies Support Strategies This section provides a summary of how the monitor was designed to be supported and how Philips provides that support. There are two main methods of repairing the monitor: • Unit exchange • Bench repair Unit Exchange The primary repair method used by Philips service personnel is unit exchange. The current design of the monitor requires testing if the case is opened. Bench Repair The secondary repair method is bench repair.
Theory of Operation and System Architecture Theory of Operation and System Architecture This section contains a high level overview of the theory of operation of the major functional modules of the monitor. Philips service providers perform Bench Repair at the assembly level. For this purpose, they should review this high level information. Please be aware that Philips only stocks assembly level parts. System Overview The monitor is a full function monitor for use on adult and pediatric patients.
Theory of Operation and System Architecture Figure 11-1 System Block Diagram 11-6 Training
Theory of Operation and System Architecture Isolated Front End The Isolated Front End section includes all of the circuitry to convert ECG, SpO2, and Temperature measurements to digital format; and to connect this information to the processor. The Respiration detection is obtained from two of the three electrodes of the ECG connections. NBP Front End The NBP section contains the pumps, valves, pressure measurement circuitry, and control circuitry for the non-invasive blood pressure measurement.
Theory of Operation and System Architecture The Contrast button operates in conjunction with the navigation wheel to determine the apparent contrast setting in the display. Changing the contrast is a change in the viewing angle. Outputs of the button and wheel are connected to the processor. Momentarily pressing the button sets the contrast to mid-range, factory-default value.
Theory of Operation and System Architecture Recorder The optional recorder module is installed in the right panel of the monitor. Refer to the C3 Instructions for Use guide for printing procedures. It provides users with the capability to obtain hard-copy records of selected vital sign information. Basic control of the recorder is implemented by two push-button controls on the recorder’s front panel.
Theory of Operation and System Architecture NBP Processing The NBP processing uses an oscillometric technique to provide needed measurements at selected intervals. This technique uses an inflatable sphygmomanometer cuff similar to those used by clinicians in routine measurements. A motorized pump inflates the cuff to approximately 180 mmHg initially, at which point the pressure effectively stops the flow of blood.
Troubleshooting Troubleshooting Service personnel concerned with troubleshooting should review the following topics in this manual: • Error Codes (see “Error Codes” on 6-3) • Boot Sequence (see “Performance Assurance Test” on 4-11) • Performance Verification (see “Performance Procedures” on 4-22) This is intended to be a practical, hands-on part of the training program. If possible, therefore, use a monitor to help you learn about troubleshooting the monitor.
