BATTERY DISCHARGE INDICATOR (HOBBS)
This indicator monitors :
 the residual capacity of batteries;
 operating hours;
 status of service down counter.
The residual capacity of the battery is monitored via an 8-LED bar display. When the left red LED
lights, the batteries must be charged to avoid damage. The LED display starts flashing as a pre-warning
signal. The lower voltage limit is adjustable via potentiometer “M” on the rear.

In order to activate a new adjustment, the unit has to be reset :
 2.35V/cell reset voltage with battery remaining in vehicle;
 2,09V/cell reset voltage after battery has been disconnected.
To maintain a good battery performance, it is recommended to limit the discharging to 80% of the
battery capacity. The recommended setting for 6V batteries is F and the recommended setting for an
industrial battery is K.
An internal relay can prevent overdischarging and damaging the batteries. The relay can be wired to
cut off the reverse direction, or energize an N.C. relay and alarm.
Turning off and on the vehicle will override the protection for 30 sec.
The current status (remaining operating hours before maintenance) of the service down counter is
indicated for a period of 5 seconds after the key switch is turned on. When it is down to 0, the display
flashes. After the maintenance, reset the counter: depress the button “R” on the rear. The service
counter is factory programmable only.
