OPERATION:
Power activated from control panel:
The outputs for internal lights (lights_1 and lights_2), external light and pump are activated directly
by the relevant keys on the control panel.
-If the service battery voltage remains under 10,5V for over three minutes, the NE185 shunt
automatically turns off all the power for lights and pump. To recharge press the relevant keys on
the control panel. If the battery is still under 10,5V, it will be deactivated again after three
minutes. In this case is advisable to disconnect all loads with the battery main switch and
recharge the battery services within 2 days.
Car battery recharge:
If there is the main supply 230V, the shunt charges the car battery with a current of about 2A. The
charge is activated automatically when the battery voltage exceeds the services of the car battery.
Side marker signal:
The side-marker output can be activated with a negative control (negative) on the JP13 block pin 5,
or with a positive control (+12V) on the JP13 block pin 4.
Services activated by D+:
The coupler relay and fridge relay are enabled immediately in one of these two conditions:
(1)
or
The coupler relay recharges the service battery with the alternator when the engine is running.
(1)
The fridge relay powers the three purpose fridge at 12V when the engine is running.
With the engine running the external light automatically turns itself off.
(1)
If there is a connection between J14 and J15 the coupler relay is not enabled.
(presence of external DC / DC converter)
ATTENTION: DC / DC converter:
If you use the DC / DC converter to charge the services battery, make the
connection between J14 and J15.
In this mode the coupler relay (RE1) is not enabled when
the engine is running.
If the vehicle not in use and the connection 230V is not present disconnect the battery service with
the battery main switch.
