Charge Ready Beep, Digital Power Regulation 7

Charge Ready Beep (6)

This touche button activates the BEEP acoustic signal. When the LED is illuminated, 1 x Beep signal indicates that the unit is ready for operation.

3 x Beep signals indicate overheating (or defect in the charge circuit), the display (6) willshow "ER"

4 x Beep signals indicate that the unit is shutting down.

Digital Power Regulation (7 and 8)

To select the desired power (in 1/10 f-stops), use the touche buttons. Minimum power is 1.5 (approx 17 Ws) and maximum power is 7.5 (approx 1100 Ws). Pressing continuously, the quick mode is activated for fast power changing.

One second later, the electronics will start to charge or discharge the unit.

The Auto Dump Function (ADF) discharges the unit to precisely the displayed power. Frequent auto dumping may cause overheating and activate the charge “cut-off”. This risk may be limited or avoided by “open flash” reduction but please note that the consequent re-charging will reduce the total number of “available” flashes

N.B. Power indicator (6) “flashes” during charging and discharging.

Digital Power Display (9)

The actual flash power is shown in an f-stop compatible format, from 1.5 (17 Ws) to 7.5 (1100 Ws). The power range is 7 f stops.

During charging or discharging the display “flashes”. In the case of overheating or malfunction the display shows "ER".

Open flash (10)

When the green LED is illuminated the flash may be released manually.

The release blocks during charging, but not during discharging.

Battery Status Indicator (13)

Approx 10 % power is still available when the last green LED goes off (at red) about 10 flashes at max. power.

In emergency, switching off the unit and waiting for some minutes will permit a few extra flashes (at slow charge).

The “intelligent” electronics saves the battery from over discharging. An "Auto Battery Save" system switches off the Ranger RX pack immediately after 4 Beep signals.
