INSTALLATION INSTRUCTIONS

13

1

Low Battery Voltage

EngineRPM > 500 AND Vbatt <

This alert activates when there is low battery voltage

9.0 for 5 seconds

with engine RPM. Make sure the 7730/77303 is properly

connected to battery voltage.

2

High Battery Voltage

Vbatt > 18.0

This alert activates when there is high battery voltage.

Make sure the 7730/77303 is properly connected to battery voltage

3

Crank Sensor

This alert activates due to weak crank sensor signal. Make sure

the crank sensor is properly located according to the installation

instructions.

5

No CAM Sync

Engine RPM > 300 AND

This alert activates when individual cylinder timing has been

configured and no optical CAM sync signal is detected. Make

sure the optical CAM sync cable is properly connected to the

7730/77303.

6

12V Output

Current > 3A for 10 ms

This alert activates when there is too much load on

Shutdown

the 12V bus that is used to power accessory modules. Make sure

there are no short circuits and the 12V bus is not overloaded.

13

Low SDcard Storage

This alert activiates when an SDCard is present and there is

less than 100 MB of storage available on the card. Remove

some data from the SDCard to remove this alert.

14

SDcard Initialization

This alert activates when the 7730/77303 cannot initialize the

SDCard. Make sure you are using the MSD factory supplied

SDCard.

15

SDcard Write Error

This alert activates when the 7730/77303 is unable to write to

the SDCard. Make sure you are using the MSD factory supplied

SDCard.

16

SDcard Read Error

This alert activates when the 7730/77303 is unable to read the

SDCard. Make sure you are using the MSD factory supplied

SDCard.

17

SDcard Missing

SDcard not presentAND data acquisition enabledAND Engine

is running.

18

Data Acquisition

DAQ memory buffer overflow

This alert activates if the interal data acquisition memory buffer

overflows. This will cause a recording to end prematurely. Try

deactivating some data acquisition channels. Make sure you

are using the MSD factory supplied SDCard.

19

12V Output Overcurrent Current > 2A for 10 ms

This alert occurs when there is too much load on the 12V bus

that is used to power accessory modules. Make sure the 12V

bus is not overloaded.

20

EEPROM CRC Error

This alert occurs if the 7730/77303 is unable to recover

configuration data from its internal EEPROM memory. The

7730/77303 will attempt to recover a back-up stored in its

internal Flash memory. Verify your configuration settings are

correct. If this error occurs frequently, contact MSD tech support

for an RMA.

EEPROM Write Error

This alert occurs if the 7730/77303 is unable to write

data to its internal EEPROM memory. If this error occurs

frequently, contact MSD tech support.

22

Data Acquisition

This alert activates if the internal data acquisition memory

buffer reaches a critical limit. This will cause some data

acquisition channels to be automatically disabled. Try

deactivating some data acquisition channels. Make sure

you are using the MSD factory supplied SDCard.
