Recorder Module, M-REC

INTRODUCTION This section provides information for maintenance and servicing of the Recorder Module, M-REC. The Recorder Module is a double width plug-in module designed for use with S/5 monitors. The Recorder Module provides real time printing of waveform and numerical data, and trend data. The S/5 Compact Monitos may include a built-in recorder. The built-in recorder is technically the same as the Recorder Module. NOTE: Printings on thermal paper may be destroyed when exposed to light, heat, alcohol etc. Take a photocopy for archive. NOTE: The Recorder Module, M-REC, cannot be used in the Extension Frame, F-EXT4.

FUNCTIONAL DESCRIPTION

2.1 Main components 2.1.1 Recorder board The function of the recorder board is to establish an interface between the recorder unit and main CPU board in the monitor. The three front panel keys are connected to the recorder unit via the recorder board. The recorder unit and the recorder board are connected together with a small connector board and 12-pin flex-strip cable.

External Communication Communication with the main CPU board is via a +5 V CMOS level RS232 serial interface, with an RS485 reset. Reset

The differential RS485 reset from the module bus generates a Recorder Unit reset signal on the Recorder Board. The Recorder Board also generates a power-up-reset, whose time constant is approximately 0.1 second. The Recorder Unit reset signal is therefore active when either the Module Bus RS485-reset or the power-up-reset is active.

+5 V priority

The recorder unit supply voltage, +15 VREC, is switched on after +5 V is present.

Front panel keys The recorder board can read the three front panel keys and pass their status on to the main CPU board. For protect the keypad signals from static discharges, zener diodes and series resistors are used. Separate pull-up resistors are not needed because pull-up resistors connecting the keypad input signals to +5 V are fitted inside the recorder. Recorder Board

SERVICE PROCEDURES

3.1 General service information Field service of the Recorder Module, M-REC, is limited to replacing faulty circuit boards or mechanical parts. Faulty circuit boards should be returned to Datex-Ohmeda for repair. Datex-Ohmeda is always available for service advice. Please provide the unit serial number, full type designation, and a detailed description of the fault.

CAUTION

Only trained personnel with appropriate equipment should perform the tests and repairs outlined in this section. Unauthorized service may void warranty of the unit.

3.2 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. The mark

? in the instructions means that the check form should be signed after performing

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.

•

Detach the module box by removing the two screws from the back of the module. Be careful with the loose latch and spring locking pin.

5 Document No. 800 1016-1

Datex-Ohmeda A/5 monitors 1.

Check internal parts: •

screws are tightened properly

•

cables are connected properly

•

EMC covers are attached properly (Rev. 02 ->)

•

there are no loose objects inside the module

? 2.

Check external parts: •

the front cover and the front panel sticker are intact

•

the module box, latch and the spring locking pin are intact

? •

3.

Reattach the module box and check that the latch moves properly.

Open the paper compartment hatch and take out the paper roll, if installed. Remove any paper chaff from the paper compartment. Clean the thermal printhead and the small glass window in front of the static brush with a cotton swab dipped in isopropyl alcohol. Avoid contact with the rubber paper roller. NOTE: Be careful to limit the application of alcohol to the thermal printhead and the window. Leave the paper compartment empty and close the hatch.

? •

Turn the monitor on and wait until the normal monitoring screen appears. Configure the monitor screen so that all required parameters are shown, for example:

Monitor Setup - Screen 1 Setup - Waveform Fields - Field 1 - ECG1 Field 2 - ECG2 Field 3 - P1 Field 4 - P2 Field 5 - PLETH Field 6 - OFF •

Insert the Hemodynamic Moduleinto a module slot. Connect a patient simulator to the module and check that all connected parameters are shown on the screen.

•

Preset recording settings:

Record/Print - Record Waveforms - Waveform 1 - ECG1 Waveform 2 - P1 Waveform 3 - P2 Delay - Off Paper Speed - 6.25 Mm/S 6 Document No. 800 1016-1

?

7.

Press the RECORD WAVE key again and check that the module starts recording the selected waveforms. Press the STOP key on the module front panel to stop recording. NOTE: If no recording appears, check that the paper roll is installed correctly - only one side of the paper is printable. Press the PRINT TRENDS key and check that the module starts recording graphical trends. Wait until the recording stops.

?

8.

Check that the quality of the recordings is acceptable.

9.

Press the RECORD WAVE key again and this time wait until the recording stops. Check that the length of the recorded waveform scale is 18.7 cm (±1.5 cm).

?

Change the paper speed setting to 1 mm/s:

Record/Print - Record Waveforms - Paper Speed - 1 mm/s Press the RECORD WAVE key and wait until the recording stops. Check that the length of the scale is now 3.0 cm (±0.5 cm).

3.3 Disassembly and reassembly Disassemble the Recorder Module, M-REC, in the following way. See figure 4. 1.

Remove the two screws from the back of the module.

2.

Pull the module box slowly rearward and detach it from main body. Be careful with the loose latch and spring pin.

3.

Open the recorder unit paper loading hatch. With a long blade screwdriver loosen the two screws at the bottom of the recorder unit housing.

4.

Disconnect the 50-pin connector from the back of the recorder unit and 5-pin ribbon keypad connector from the recorder board.

The recorder unit and front panel frame can now be pulled out of the main body. The front panel frame is pulled out of the recorder by pulling rearward. The recorder board is attached to the metal chassis with four screws.

CAUTION

The recorder board is fixed to the metal chassis at the factory in a definite position. The recorder board and chassis must therefore not be separated. To reassemble the module, reverse the order of the disassembly steps.
