4-12 Setting Up and Using Laser Alignment Fixtures
After the “Discharge” cycle has completed the charger automatically begins
fast charging and the “Fast” indicator light turns on. To avoid the battery
memory concern, use the “Discharge” mode when you have more than 20
minutes to charge the sensor head batteries. The typical charge cycle is as
follows:
Note
After power has been applied to the charger and the sensor
head have been placed in it, if none of the LED's for that sensor
head are lit then the contact between the sensor head and
charger may not be sufficient enough to charge the batteries.
No LED's lit indicates a “no battery present” state. If this
occurs, remove the sensor head from the charger and try
reseating it back into the charger.
Note
After a charging cycle has begun, if that charging cycle is inter-
rupted (e.g. disconnecting the power to the charger or
removing the sensor head from the charger) the charging pro-
cess described above begins again from the beginning. There-
fore, if the charger cycle is interrupted while the “Fast” charge
mode is in progress then the charger will then automatically
begin trickle charging after “Pending.”
