MICROPROCESSOR RESET PROCEDURE

The LINK 2000 uses a microprocessor to perform all of its calculations and functions. We have worked very hard to ensure a stable, trouble-free product. However, like all computer products, the unit is sometimes susceptible to power supply dips or surges that can cause erratic behavior or memory errors. If you detect a problem, please use the following procedure to reset the microprocessor—you may also need to reset the memory to the factory defaults as described on the next page. If you reset to factory defaults be sure and set up appropriate values for battery capacity, battery type, ambient temperature, and Peukert's exponent as previously described. Please read the entire instruction set before beginning the procedure.

TO RESET FROM A LOCKUP, ERRATIC DISPLAY, OR ERRATIC BEHAVIOR

1)Disconnect from shorepower.

2)De-power the meter by removing the fuse from the red wire. If the red wire isjumperedtotheblueorvioletwires,removethefusesintheappropriatewire to remove power to the unit. If your meter is an alternator regulator model you can de-power the meter by removing the gray ribbon cable from the monitor terminal board and reconnecting it.

3)Wait at least 30 seconds before reconnecting the fuse (or the ribbon cable). When the fuse is reconnected use a continuous motion. If the meter is intermittently powered and de-powered several times in a short period, the microprocessor may lock up.

4)Press the INVERT and CHARGE buttons so that their LEDs are illuminated.

5)Restore shorepower. After a few seconds you should see the AC STATUS light illuminate and the charge status lights come on indicating the CHARGE mode. (If the battery is full the CHARGE light will only be on for a short time before the Accept LED comes on.)

6)Check to see that your battery capacity, battery type, ambient temperature, Peukert's exponent, charged voltage parameter, and any other values you mighthavepreviouslysetuparestillcorrect.Iftheyare,endhere;ifnot,change them to the appropriate values or follow the procedure on the next page for resetting to factory values.
