MAINTENANCE AND CLEANING

Preventive Maintenance

Preventive maintenance is recommended to be performed on the ELI 350 cardiograph once every
12 months.

A preventive maintenance report to document the maintenance activity performed is located at the end of
this section of the manual.

WARNING: Preventive maintenance is to be performed by Mortara authorized service

personnel only.

Maintenance Procedure

 Turn on the cardiograph and print the unit configuration information from the “System Settings”

page.

 Remove the upper housing per section 3 of this manual.
 Remove the four (4) screws from the writer assembly, without disconnecting the cables, to

perform the complete visual inspection below.

 Perform a visual inspection of the following items:

o Enclosure/Housing – Look for damage or cracks in the external housing or enclosure that

could possibly expose the device to the introduction of foreign objects or fluids. Attention
should also be paid to areas that could expose an operator or patient to internal circuitry
of the device.

o Contamination – Look for any contamination that may have occurred over time that could

not be seen with the housing in place.

 Fluid damage (perhaps caused during device cleaning)
 Debris on or behind display shield
 Battery leakage (lithium and main battery)

o Internal Cabling – Look for cracked, pinched or partially disconnected cable connections.
o Fuse Ratings – Verify the battery and AC line fuses match the device labeling.
o Markings and Labeling – Verify all labels and device markings are clearly visible and

legible to the device user and have not been worn off or rendered unreadable through
the use of harsh cleaning agents.

3

SECTION 2

o Integrity of Mechanical Parts – Verify the following items are properly secured to the

device and have not become loose or damaged through usage over time.

 AC Inlet
 Patient Input Connector
 Communication ports and antenna
 Writer mechanics/latching mechanism
 LCD Assembly

Power Testing

Note battery age (if possible). This information can be found on the “date code” sticker on the battery
(use the earliest date crossed out on the label); or on a sticker located on the bottom of the unit.

Based upon customer usage, and the age of the main battery, replace as needed and place a sticker on
the bottom of the unit to identify when the battery was replaced.

If the internal lithium battery is older than 5 years it should be replaced and a sticker should be placed on
the bottom of the unit to identify when the lithium battery was replaced.

Ensure the battery is fully charged before performing the battery tests; the test limits are based on a fully
charged battery.

Disconnect the AC power cord to begin this section of tests.
With the upper housing off of the unit, disconnect the battery cable from the positive terminal.

o Battery Open Circuit – Measure the open circuit battery voltage using a volt meter across

the battery terminals, the meter should read greater than 12.5vdc.

o Battery w/Load – Measure the battery voltage using a volt meter with a power resistor

load (10ohm, 20watt) across the battery terminals. After loading the battery for
approximately 5 seconds, the meter should read greater than 11.7vdc.

o Off Current – Connect a current meter in line with the positive battery terminal to the

motherboard. With the unit in the “off” state the meter should read less than 450 micro
amps.

o On Current – Set the current meter to a setting greater than 5 amps, and turn the unit on.

Once the unit powers up to the main menu, the current should read less than 2.7 amps.

o AC Charging Current – Insert the AC power cord and verify that the current draw from the

battery reverses polarity (starts to charge the battery) and the value starts decreasing in
magnitude as time increases.

o Battery Charger Output Voltage – Disconnect the current meter and measure the battery

charger output voltage between the disconnected positive battery cable and the negative
battery terminal. It should read between 13.0 and 14.0vdc.

Reconnect the battery cable to the positive terminal and verify all other internal cables are properly
connected. Install the writer assembly screws and the upper housing on the cardiograph.

Functional Testing

 AC/DC LED

o Connect a power source to the AC inlet of the UUT. Verify the AC LED on the

keyboard illuminates continuous. With the display in the upright position, turn the unit
on. The BATTERY LED will illuminate continuously if the battery is charging, it will
turn off when the battery is fully charged or when the display is completely lowered.

 LCD/Tilt Switch

o Verify the LCD backlight is on and there are no flickering or missing lines/pixels.
o Slowly lower the LCD, verify the backlight turns off before or it is completely lowered.

Raise the LCD and verify the backlight turns back on.

 Writer

o Open and close the writer drawer. Verify smooth operation of the drawer. Verify that

the drawer unlatches without sticking. Verify that the drawer latches completely.

o From the main screen, click on SETTINGS, enter PASSWORD “Print test” and then

press the Enter key. Verify that a test page is printed and the writer stops on the cue
mark. The perforation on the paper should line up with the tear edge on the UUT.
Assure there are no gaps in the print and darkness is uniform across the entire page.
Verify no gear skipping and proper paper tracking as the writer prints (you might
need to print 3 or more pages to verify this).

 ECG & Keyboard Matrix

o Using a Mortara 10-lead patient cable, connect an ECG simulator to the UUT. Set

the simulator to an appropriate heart rate and amplitude to enable visual confirmation
of the correctness of the ECG printout (comparison to a sample printout from a
“known good” device is recommended). Press the AUTO key to capture an ECG.
Enter Last Name “PARCFL8”, click on OK to continue and then print the ECG.

NOTE: “PARCFL8” ensures the keyboard matrix is fully tested. Verify there is an
audible beep with each key press.

o Verify that 12 ECG traces print with the correct heart rate, amplitude and

morphology, then assess the overall print out quality (ensure there is uniform
darkness across entire printout).

 ECG Noise Test

o Connect a Shorting Block (TF-0063) or equivalent to the UUT and set the ECG gain

to 20mm/mV. Print a Rhythm strip (approx. 1 page). Verify that no channels have
more than 0.5mm of baseline noise.

 Communication options

TROUBLESHOOTING AND CONFORMANCE TESTING

Introduction

Since repair of the ELI 350 is limited to replacement of subassemblies the troubleshooting guide does not
extend to the component level

NOTE: Remove the battery fuse and AC power during any disassembly necessary for servicing.

Troubleshooting

AC power connected to unit, back-light is on, nothing on display.

1) Check AC fuses.

2) Does unit power up on battery?
A) If yes, there is an AC power supply problem. Replace the motherboard.
B) If no, power supply or battery problem. Replace motherboard and check battery for possible
replacement.

3) Check Keyboard/LCD cable going to the keyboard and the motherboard for breaks or punctures in the

wire and that the connectors are not pulling out of the wires. If disconnected reconnect and test again.

4) Replace the Keyboard/LCD cable.

With AC power on nothing displayed on LCD.

1) Press any key on the keyboard. If speaker tone is heard there is a possible LCD problem. Replace

LCD.

Unit works on AC power but not on battery.

1) Check battery fuse.

2) Open unit and check battery connections.

3) Check the voltages and currents found in the Conformance Testing section.

4) Replace the battery if charging circuit is within tolerance.

Unit does not dim display in a darkened room.

1) Go to the settings screen and verify the Brightness AC and Brightness Battery settings are set to Auto.

2) If not set them to Auto.

3) Save the settings.

4) Back at the main screen, cover the light sensor on the top left corner of the screen housing, and the

screen should begin to dim in 1 second intervals.

5) Uncover the sensor, and the screen should brighten again.

Unit turns on, no waveform is displayed on the LCD.

Press any key on the keyboard, if no response there is a possible communications problem between front
end board and motherboard.

1) Replace cable between front end and motherboard.

2) Replace front end board

3) Replace motherboard

79

SECTION 4

No keyboard functions and LCD is frozen.

1) Remove AC power.

2) Remove battery fuse from unit and leave out for 10 seconds.

3) Install battery fuse.

RS-232 Transmit/Receive Problems.

Make sure that the baud rate set in the configuration matches that of the system that is being transmitted
to or received from. If the baud rate is set correct there is a problem with either the transmission cable or
the RS232 portion of the motherboard and the motherboard should be replaced.

Optional Modem Transmit/Receive Problems.

If the unit does not transmit via the modem the first item to check is the configuration. Make sure that a
telephone number is entered and that the number is correct. The next item to check is the modem
initialization string (please see the configuration section of this manual or the operator manual).

Unit does not go into standby mode.

If the unit does not go into “Stand-by” mode when the LCD is lowered, check the cable connections from
the Tilt-switch assembly to the motherboard. If this connection is OK, inspect the cable for damage or
loose connections.

Unit appears to be “Locked-up.”

The ELI-350 unit is equipped with a software reset function that can be used to remove the unit from an
unresponsive state. This can be done by holding the ON/OFF button down for 8 seconds, and then
releasing the button. Wait 5 seconds and press the power button one time.

Conformance Testing

Conformance testing is to be performed by Authorized Mortara Service Representatives to verify the
device is functioning correctly after repair operations have been performed. Testing results should be
documented on the test data record at the end of this section of the manual.

Power Testing

Note battery age (if possible). This information can be found on the “date code” sticker on the battery
(use the earliest date crossed out on the label); or on a sticker located on the bottom of the unit.

Based upon customer usage, and the age of the main battery, replace as needed and place a sticker on
the bottom of the unit to identify when the battery was replaced.

If the internal lithium battery is older than 5 years it should be replaced and a sticker should be placed on
the bottom of the unit to identify when the lithium battery was replaced. [Refer to ELI350 Lithium Battery
Replacement TU _1-5-11_.pdf document available from Technical Support]

Ensure the battery is fully charged before performing the battery tests; the test limits are based on a fully
charged battery.

80

SECTION 4

Disconnect the AC power cord to begin this section of tests.
With the upper housing off of the unit, disconnect the battery cable from the positive terminal.

o Battery Open Circuit – Measure the open circuit battery voltage using a volt meter across the

battery terminals, the meter should read greater than 12.5vdc.

o Battery w/Load – Measure the battery voltage using a volt meter with a power resistor load

(10ohm, 20watt) across the battery terminals. After loading the battery for approximately 5
seconds, the meter should read greater than 11.7vdc.

o Off Current – Connect a current meter in line with the positive battery terminal to the

motherboard. With the unit in the “off” state the meter should read less than 450 micro amps.

o On Current – Set the current meter to a setting greater than 5 amps, and turn the unit on. Once

the unit powers up to the main menu, the current should read less than 2.7 amps.

o AC Charging Current – Insert the AC power cord and verify that the current draw from the battery

reverses polarity (starts to charge the battery) and the value starts decreasing in magnitude as
time increases.

o Battery Charger Output Voltage – Disconnect the current meter and measure the battery charger

output voltage between the disconnected positive battery cable and the negative battery terminal.
It should read between 13.0 and 14.0vdc.

Reconnect the battery cable to the positive terminal and verify all other internal cables are properly
connected. Install the writer assembly screws and the upper housing on the cardiograph.

AC/DC LED

Connect a power source to the AC inlet of the UUT. Verify the AC LED on the keyboard illuminates
continuous. With the display in the upright position, turn the unit on. The BATTERY LED will illuminate
continuously if the battery is charging, it will turn off when the battery is fully charged or when the display
is completely lowered.

LCD/Tilt Switch Test

1.) Verify the LCD backlight is on and there are no flickering or missing lines/pixels.

2.) Slowly lower the LCD, verify the backlight turns off before or it is completely lowered. Raise the LCD

and verify the backlight turns back on.
(For Software Version 1.4.4.1 the On / Off button must be pressed.)

3.) Change the “Battery Timeout” to “5 Min” or “10 Min” depending on the version of software.

4.) Change “Brightness Battery” to “Auto” and “Brightness AC” to “Auto”.

5.) Holding your finger over the light sensor located on the top of the LCD Display, verify the backlight

intensity decreases slowly.

6.) Remove your finger from blocking the light sensor and verify the backlight quickly returns to full

brightness.

81

SECTION 4

Speaker Test

1.) Turn the unit on.

2.) Turn the click knob or press keys on the keyboard.

3.) Verify volume control functions.

Date/Time Test

1.) Turn the unit on.

2.) Go to the settings menu and change the date and time.

3.) Verify new date and time saved.

Keyboard Test

1.) Turn Unit on.

2.) Use the click knob to select the ID field.

3.) Start pressing the alpha keys on the keyboard and verify that they are displayed on the screen. When

the characters reach the end of the line, press the enter key and continue entering characters in the
next data field.

4.) If all characters are present the test has passed. If any of the characters are not displayed there is a

possible keyboard problem.

Cue Sensor Calibration

NOTE: This test should be performed with the AC power turned on.

1) Install paper into the unit with the cue mark approx. 1 – 2 inches away from the tear bar. Make sure

that the cue sensor is seeing white and not any markings on the paper.

2) Use a DMM to measure the DC voltage at test point P15 on the motherboard with respect to ground

(GND5). Adjust R270 on the motherboard to between 1.95 V-DC and 2.05 V-DC at test point P15.
Set this as close to 2.0 V-DC as possible.

3) Perform either the Writer test or print a test ECG. The paper should cue to the next sheet of paper,

print and then advance to the beginning of the next sheet of paper.

4) If the Writer test is performed the results should be compared with the test printout in this manual.

Writer Tests

1.) Turn the unit on.

2.) Take an ECG using the method described in the operator manual.

NOTE: This test should be performed with the AC power connected to the unit.

Description of printout: The ECG that is printed should be clean, without missing segments. When

printing an ECG at different paper speeds the calibration pulse printed at the beginning of each trace can
be used to check the paper speed. Check the calibration pulse by measuring the width and amplitude of
the pulse at the beginning of each line of ECG tracing. Use the following table for the correct
measurements.

82

SECTION 4

NOTE: The measurements should be made using a ruler and not the grid on the paper.

Paper Speed

5mm/sec 1mm
10mm/sec 2mm
25mm/sec 5mm
50mm/sec 10mm

Gain Setting

5mm/mV 5mm
10mm/mV 10mm
20mm/mV 20mm

3.) Open and close the writer drawer. Verify smooth operation of the drawer. Verify that the drawer

unlatches without sticking. Verify that the drawer latches completely.

4.) From the main screen, click on SETTINGS, enter PASSWORD “Print test” and then press the Enter

key. Verify that a test page is printed and the writer stops on the cue mark. The perforation on the
paper should line up with the tear edge on the UUT. Assure there are no gaps in the print and
darkness is uniform across the entire page. Verify no gear skipping and proper paper tracking as the
writer prints (you might need to print 3 or more pages to verify this).

ECG Test

1.) Connect a simulator to the patient cable and connect the patient cable to the unit.

2.) Turn the unit on.

3.) Enter the ID screen and enter a test patient name.

4.) Press the Auto key. The unit will acquire the ECG and depending on the units’ configuration, will print

the ECG.

5.) Verify that the printed ECG is correct for the simulated input to the unit.

6.) For units with the optional 15 lead configuration, acquire a 15 lead ECG sample using the Settings

sub menu ECG SETTINGS to preset the ELI 350 for:

• 15 & 12 lead (V3R,V4R,V7)

• 15 & 12 lead (V7,V8,V9)

• 15 & 12 lead (E1,E2,E3)
