Extension Frame, F-EXT4 and Extension Module, M-EXT

INTRODUCTION The Extension Frame, F-EXT4 is designed for use with S/5 monitors and provides four additional module slots, and enables taking the measuring modules near to the patient. The extension frame, F-EXT4 is connected to the monitor with the extension module, M-EXT, which reserves one module slot. NOTES: •

Only one F-EXT4 can be connected to the monitor at a time.

•

The following modules cannot be used in the F-EXT4 −

Recorder Module, M-REC

−

Memory Module, M-MEM

−

Interface Module, M-INT

−

Compact Airway Modules, M-Cxxxxx

•

Do not use identical modules simultaneously in the extension frame and in the host monitor.

•

When the extension frame is used with the S/5 Anaesthesia Monitor the F-CU8 must be of rev. 03 or later.

Figure 1

F-EXT electronics unit block diagram

The Extension Frame, F-EXT4, contains the module mother board, power supply board, and space for four single-width or two double-width modules. The electronic unit receives +32 V from the monitor frame and generates from it necessary operational voltages for the inserted modules. The received +32 V is passed through fuse (F1) and filtered and led to power supply components. There is overvoltage and undervoltage protection for input voltage, the input voltage is set so that it can vary between +18.5 V and +36.0 V.

3 Document No. 8001007-1

Datex-Ohmeda S/5 monitors The purpose of the soft start is to raise input voltage +32 V slowly (about 1 second) to the maximum value so that capacitors in power supply components' circuits have time to get charged. This enables extension frame to be connected to monitor frame during operation. There is also overvoltage protection for outgoing supply voltages. The overvoltage limits are +5.95 V (+5 V) and +17.50 V (+15 Vd). Signal Routes There are two connectors which are used for data communications ( RS485), for supply voltages (+32 V, +15 Vd, +15 Va, and +5 V), for grounds connections (GNDD, GND&SHIELD) between the power supply board and module mother board.

3.1 Service check These instructions include complete procedures for a service check. The service check is recommended to be performed after any service repair. However, the service check procedures can also be used for determining possible failures. The procedures should be performed in ascending order. The instructions include a check form (Appendix A) which should be filled in when performing the procedures.

?

in the instructions means that the check form should be signed after performing The mark the procedure. The procedures are designed for monitors with S/5 monitor software of revision 01. However, most of the procedures also apply to monitors, which contain some other monitor software type/revision.
