Product Family: LIFEPAK 20

Subject: Technical Bulletin for the LP20 Family

PURPOSE

The purpose of this technical bulletin is to provide additional troubleshooting, part information, and repair clarification to support the service and maintenance of the LP20 family of products.

SCOPE

The scope is limited to the LIFEPAK 20 family of products and does not replace the validated repair process contained in the service manual. This technical bulletin is to be used in conjunction with validated repair processes to provide additional clarity in support of servicing activity.

TROUBLESHOOTING

This section is intended to provide additional troubleshooting information to aid the technician in the identification and diagnosis of possible root cause of a device failure. Use the repair process contained in the service manual to perform any component and sub-assembly replacements.









Section Situation/Scenario Information/Repair Action

Therapy (S/W version below 3202609-030) The LP20 takes over 16 seconds to charge to 360J.

Update device with the latest version of software as outlined in PC000226

Display (S/W version below 3202609-020) The LP20 display is completely blank, with a green tint


Power (S/W version below 3202609-016) If the battery in a LP20 is substantially depleted, and the device is unable to recharge the battery. Service code 5112 may also be logged


The LP20 may lock-up when attempting to power-up on DC power within two seconds after removing AC power. Issue found in S/W version 3202609-028, -30, -032, -038


(S/W version 3202609-038) The LP20 will not report low battery message


1.LP20 will not power ON using battery power. 2.LP20 powers On/Off by itself. 3.LP20 is reported to not turn ON when connected to AC or Battery power

See section 3.1 LP20/20e Power Module Troubleshooting below

Error Code (S/W version below

3202609-016) Code 300B, 5032, 503B, 5004, 9021 appears in the Service Log


(S/W version below

3202609-022) Code 9C1E appears in the Service

Log.

1. Update device with the latest version of software.

2.Perform TCP – Defibrillator Calibration. Clear Service Log.

3.If S/W didn't correct the problem, replace Therapy PCB

Error code 5106 – Power supply out of tolerance

1.If power supply voltage is >14 Vdc, replace the Power module

2.If <14 Vdc clear error and perform PIP

3.1 LP20/20e Power Module Troubleshooting

3.1.1 Scenario

The LIFEPAK 20/20e, when operating from Battery Power, is unable to turn ON. The device will power ON when connected to AC.

The LIFEPAK 20/20e powers ON/OFF by itself.

The LIFEPAK 20/20e is reported to not power ON either on AC or DC Power.

3.1.2 Action

When notified of any of the above reported symptoms, request Customer to leave the LIFEPAK 20/20e connected to AC Mains power with the Unit powered OFF until you can arrive. Note: It can take up to 48 hours to show this particular failure mode. Before opening up the LIFEPAK 20 device, attempt to duplicate the reported symptom. If the LIFEPAK 20/20e is able to power ON when connected to AC Mains power, connect the unit to a service laptop and open the combined loader application. Check the Diagnostic Log for a “5109” and “5043” Error code. Replace A03 Power Module if codes are present. If diagnostic codes aren’t displayed, perform A03 Power Module voltage check. Remove the Top Case as outlined in Section 9-22 of the LIFEPAK 20/20e Service Manual, with the following exception: do not disconnect the defibrillator from AC Power as indicated in step 1. To measure voltages on the Power Module, temporarily reposition the A13 Energy Capacitor by removing two 4-40 x .312 screws from the rear of the capacitor brackets. Lift the A13 Energy Capacitor out of the Capacitor Brackets and rest on the Printer Shroud as shown in picture below.









Pin 2 Pin 3

Reconnect the A07 Battery (A07 Battery was disconnected during Top Case removal).

Once the A07 Battery has been re-installed, wait 5 minutes to allow FL4 voltages to reach equilibrium.

Using a Digital Multi-meter, measure the voltage on Pin 2 and Pin 3 of FL4 as shown in the picture

below (attach the meter ground lead to the Ground Lug of the Power Module Heat Sink).









The Voltage measured on Pin 2 of FL4 should be greater than 4.7Volts. The Voltage measured on Pin 3 should be less than 0.05Volts. If either of the Voltages measured at Pins 2 or 3 of FL4 exceed the specified voltage limit then remove and replace the A03 Power Module.

PARTS

This section provides clarity on repair part numbers that may have changed or been revised since the last release of the service manual. Refer to the service manual for detailed part replacement procedures.

4.1 LP20/20e Redux Replacement Parts

Check the device’s Redux configuration to determine whether it is Pre, Redux or Post-Redux by checking the device software via Combined Loader or in the Device Data screen in the Service menu. See PC000226 for software/hardware compatibilities. Use the flow chart below as a guide to help the Service Representative determine which part is required for Pre Redux, Redux, and Post Redux devices.

CMM Software Note: When replacing the UI board and installing CMM software on a Post-Redux device, you MUST install the non-CMM software first. After the non-CMM software is installed, you can proceed to updating the device to CMM software. Installing CMM software first will cause a display anomaly on the LP20/20e device. LP20: Load Non-CMM software 3202609-167 or newer first, then load 3202609-169 or newer. LP20e: Load Non-CMM software 3202609-168 or newer first, then load 3202609-170 or newer.
