MINIMAL VOLTAGE CONTROL
AMPEREMETER
DRINK WATER TANK REFILLING
ELECTRONIC TANKPROBE
An electronic device switches all the 12V mains off, when the leisure battery reaches the minimal
voltage level of 10V. It is possible to switch on again all the mains for about 1 minute by switching
off and then on again the main switch.
They are also automatically switched on again when the voltage is > 12V.
The fridge, the electrical step and the mains powered directly from B2 are excluded from this
device.
The amperemeter is inside the DS-520AN module.
- It measures the current of the leisure battery, users’ consumption and recharge through battery
charger, engine alternator and solar panels.
- Measure range is: -40A ÷ +40A.
- Measure is carried out as difference between charging and discharging currents: a positive value
indicates a charging current, a negative value indicates a discharging current.
To measure the charging of a sole source (battery charger, alternator or solar panels), turn off all
users and other recharging sources.
To measure the consumption of a sole user, disconnect all recharging sources and all
uninterested users.
This function is used during the drink water tank refilling and it shows the level reached by the
water.
You switch on this function by visualizing the drink water tank and by keeping pushed the tank
switch for more than 3 seconds.
When this function is on, you see getting lightened, in sequence, the horizontal segments of the
number ref. 18 and the panel emits sounds in order to warn that the tank is getting filled:
1 short sound at 75%, 2 short sounds at 85% and 1 long sound at 95%.
The electronic tankprobe mod. “SPE” is a capacitive tankprobe. It is powered with 5V and a back-
signal from 0 to 2,5V.
Each 8 seconds the microprocessor gives power to the tankprobe; it is also powered each time you
pust the tank-test button. This was studied in order to avoid useless consumption.
The tank probe has been already programmed by CBE, but it is still possible to check the correct
working of the tankprobe and its setting by following these instructions:
- activate the function
- in this way the tankprobe gets a continue power supply of 5V, so that you can control with a
voltmeter the back-signal of 2,5V and you can also adjust, by using the tankprobe’s trimmer,
possible small variations. (e.g.: value “0 V” = 0 %, value “2,5 V” = 100 %).
- switch the main switch off and then on again.
“DRINK WATER TANK REFILLING”
For this test the tank must be full.
