In the Powersave mode the measurement takes place in dependence of the supply voltage:
Above 13V the Powersave mode is switched off automatically. Below 11,5V automatically switched on.
If the supply-voltage is between 11,5 - 13 V a measuring cycle takes place every 30 minutes;
if the supply voltage is below 11,5V a measuring cycle takes place every 2 hours.
A measuring cycle lasts 5 minutes, thereby the sensors are scanned each 5 s.
A new measuring cycle is started each time when a button is pressed. During the cycle-interval the display
shows the latest measured values.
In 24V- operation double values are applying.
ADJUSTMENT TO THE GEOMETRY OF THE TANK / COMPENSATION (TANK 1-4):
Tank1...4 : Adjustment of tank geometry
With non rectangular tanks the level height is not proportional to the content of
liquid in the tank. By means of the compensation value this can be considered
in the display. The compensation value changes the tank characteristic in such
a way that the indicated level is approximated to geometry of the tank.
The value to be entered is value the tank display should indicate with the half
level height of the tank is. The following examples shows which values the
compensation value with different geometry will be:
If tank geometry is strongly deviating from the examples, then the correction
value can be determined.
The correction value is computes by capacity of level iof half height divided by
the capacity of entire level in the tank multiplyied by 100.
Capacity of half level height
Correction value K = ------------------------------------ x 100
Level of fuel in the tank entirely
Example: The tank has a total volume of 150 l with a maximum filling height
(tank height) of 50 cm.
In order to determine the correction value, the tank is filled up only up to the
half filling height (= 25 cm). Computationally or by filling up a value of 65 l
results.
Inserted into the formula results for the correction value a value of:
K = 65 l/150 l x 100 = 43
This is deposited accordingly now in the Setup.
