Recharging Batteries - Microgate Racetime 2 User Manual

Racetime 2 - OptoJump Program

7 Recharging batteries

The recharging of Racetime2's internal batteries is managed entirely by the microprocessor which
controls all of the chronometer's functions. Consequently, it has been possible to implement a
recharge control which guarantees maximum battery efficiency at all times, at the same time
prolonging the chronometer's operating life.
To recharge the batteries, connect the Racetime 2 battery recharger to the corresponding socket on
the back of the device.
If the chronometer is off, information on the current status of the battery recharge management
function will be immediately shown on the display.
Specifically, the following messages will appear on the first line of the display:
7.1.1.1 Status/message Function description
Maintenance
Discharge
Recharge
If you see the letters 'Vext. Ins' blinking on the first line of the display, this means that the voltage
supplied at the recharge/supply input is insufficient. Attention: when external power is insufficient,
recharging is interrupted and so cannot be completed correctly and within the time anticipated.

at the beginning of a recharge cycle, the

recharge in progress. On the first line of
the display, the time still to go until
the end of recharge is shown.

If the chronometer is in 'Maintenance', press F1 (A:
Rep.charge/disch.) to begin a new charge cycle. This will start
the running down of the batteries. The duration of this
discharge phase is variable and depends on how fully the
menu
batteries are charged. (The time needed to discharge can last
up to four hours).

After discharging the batteries, Racetime2 will automatically
begin to recharge; this takes seven hours. After recharging,
the words 'Charging over - OK' indicate that the process has
been correctly completed. If, however, battery malfunction
has caused premature interruption of charging, the messages
'Err. Batteries (LV)' (insufficient battery voltage) or 'Err.
menu
Batteries (HV)' (battery voltage too high) will appear.
