7.1. RECHARGE
MANAGEMENT
Recharging the Polifemo batteries can only take place with the photocell off and is managed
'smartly' by the microprocessor in the photocell itself. The standard procedure is to discharge the
batteries and then to fully recharge them. Recharging starts after insertion of the power supply jack
with sufficient voltage (Vch>8V) and the photocell off.
The following steps are carried out by the program which manages recharging:

Switching on the photocell or lack of recharge voltage result in interruption of the recharge
procedure.
7.1.1. IMMEDIATE
RECHARGE
If immediate battery recharge is required without first discharging the batteries, put the switch (Fig.
1 n° 5) to ON for an instant and return rapidly to OFF. The recharge management program will not
first discharge the batteries (steps 3 and 4)
Only in exceptional circumstances should the batteries be recharged straightaway without being
first discharged as this shortens their life.
7.1.2. ANOMALIES
Any anomalies occurring during the recharge procedure are signalled by slow blinking of the red
LED and the sound signal BOOP-pause-BOOP. When an anomaly is detected, the recharge cycle is
interrupted.
