There is an earthing screw on the mechanical adaptor which may be used as a

functional earth terminal. If no earth connection is available because of the

particular installation circumstances (e.g.: if the tank is plastic), the functional

earth must be connected. We recommend using a 16 AWG cable and as short

a line length as possible.

The level switch ENS 3000 must be installed as near to vertically as possible in

the tank. If the ENS 3000 is not mounted vertically, then the accuracy of the

ENS deteriorates with increasing angle of incline. (Additional inaccuracy if ENS

is at an angle of 5°: approx. ±0.5% ; additional inaccuracy if at an angle of 10°:

approx. ±1.5%).

3. Commissioning

Method of determining the offset value:

We suggest the following procedure for determining the value of the fluid

level offset (difficult when display is showing nTop or nMin):

Start by installing the ENS 3000 in the tank, then check if the ENS 3000 is

flashing or is showing a value greater than zero. If the display is flashing,

the level is outside the active measuring zone (level too high or too low). If

the level is too low, gradually increase the level – by adding fluid – until the

value 0 is displayed. Then remove the ENS 3000 from the tank and use a

measuring device to measure the depth of fluid inside the tank. Depending

on the model, this depth is entered at menu point

in “inch “ or “cm “.

If the display is not flashing, or if the level is too high, gradually reduce the level

– by draining the fluid – until the value 0 is shown in the display. After removing

the ENS 3000 from the tank follow the procedure described above.

Important:

Before commissioning select the type of fluid: oil or cooling lubricant. For the

procedure, please see Point 7.2.

Note:

After detecting a valid measurement, the ENS 3000 with 4 switching points

will check if faults are present in the active zone. If they are higher than the

measurement detected it corrects them. After approx. 15 minutes these

corrections are stored permanently, only

if the type of fluid is set as oil.

Menu point

is used to reset faulty corrections and the learning phase

re-starts (see Point 7.2 Summary of the basic settings).
