4 Installation
4.1 GENERAL INSTALLATION NOTES
The electronic level switch ENS 3000 should be fastened at the metal collar of the adaptor
using a mounting device which grips as much of the metal collar as possible. Any device
large enough to hold a metal collar of 0.866 inch diameter can be used.
The electrical connection must be carried out by a qualified electrician according to the
relevant regulations of the country concerned (VDE 0100 in Germany). The level switch
housing must be earthed correctly at the same time. If mounted inside a tank, the housing
must be earthed separately (i.e. screened cables or connection of functional earth to the
ground screw at the hexagonal nut).
For simple and reliable installation, we recommend using the mounting accessory from
HYDAC ELECTRONIC (see Section 16.2 Accessories, Mechanical Connection).
To ensure safe operation of the ENS 3000 the following conditions must be met:
•The active range of the probe
must extend down into the tank
and must be clear of the tank
walls.
•When installing in small plastic
tanks, the unit must be installed
as near as possible to the
centre of the tank.
•When installing in metallic rising
pipes (e.g. mounted on the side
of the tank) the sensor must be
mounted in the centre of the
tube. We recommend that the
internal diameter of the tube is
≥2.36 inch
•Any metallic objects (e.g.
metallic pipes or baffles) inside
the tank must be at least 2.36
inch away from the active zone
of the sensor. Otherwise they will be recognised as mounting devices and the
measurements will be distorted.
•When mounting in tanks, the distance between the sensor and the walls of the tank
must be at least 0.79 inch.
•In order to prevent the material of the tank cover from affecting the measurement
results, the active zone must be a minimum distance below the tank cover.
The required minimum distances are dependent on the probe length.
The necessary minimum distances are given in Section 4.2 (Installation using
HYDAC Accessories).

4.3 IMPORTANT SAFETY NOTES
Additional installation suggestions which, from experience, reduce the effect of
electromagnetic interference:
•Make line connections as short as possible
•Use shielded lines
•The cable shielding must be fitted by qualified personnel, subject to the ambient
conditions and with the aim of suppressing interference.
•Keep the unit well away from the electrical supply lines of power equipment, as well as
from any electrical or electronic equipment causing interference.
•Always connect the earthing screw of the ENS 3000 to the earthing rail (e.g. in the
control cabinet). We recommend using a 16 AWG cable and as short a line length as
possible.
The level switch ENS 3000 must be installed in the tank as near to vertically as possible. 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%).
CAUTION:
The electronic level switch ENS 3000 must not be used at positive pressure. Short-
term pressure of up to 40 psi for no longer than 1 minute is possible without
causing damage.

5 Starting up
CAUTION:
Before commissioning select the type of fluid to be measured (default setting: Oil),
procedure see chap. 9.2.
NOTE:
After recognizing a valid measurement value, the ENS 3000 (version with 4 switch
points), checks for diversion points within the active zone beyond the recognized
measuring value. These will be corrected immediately. After approx. 15 minutes,
the corrections will be stored permantently, but only if the set fluid to be measured
is oil.
Menu point is used to reset faulty corrections and the learning phase re-starts
(see Chapter 9.2 Summary of the basic settings).
Method of determining the offset value:
We suggest the following procedure for determining the value of the fluid level offset:
¾Installation resp. mounting of ENS 3000 inside the tank
¾Check: is the display flashing or does it show a value greater than zero.
¾If the display flashes, the level lies outside the active measuring zone (level too
high, resp. level too low).
If the system reports low level, the fluid level will gradually be filled up by until 0 is
displayed. Then, the ENS 3000 is removed from the tank and the fluid level inside
the tank is determined by a measuring unit. Depending on the model, this value is
displayed in the menu in " inch " or " cm " after having been determined.
¾If the display shows value 0 or if high level is reported, the level is gradually
reduced by draining the fluid until the value 0 appears in the display. After removing
the ENS 3000 from the tank the process is as described above.

8 Output function
8.1 SWITCHING OUTPUTS
The EDS 3000 has either 1, 2 or 4 switching outputs.
The following output signals can be set in the basic settings:
8.1.1 Switch point setting (SP)
One switchpoint and one hysteresis can be set for every switching output. The particular
output will switch when the set switch point is reached and switch back when the
measurements drop below the switch-back point. The switch-back point is always
determined by the set hysteresis.
(switching point minus switching hysteresis = switch-back point)
Abbreviations: "S.P.1", "S.P.2", "S.P.3" , "S.P.4" = switching point 1 to 4
"HyS.1", "HyS.2", "HyS.3" , "HyS.4" = hysteresis 1 to 4
8.1.2 Window mode (WIN)
Operating in window mode allows the unit to monitor a range. An upper and a lower
switching point which defines the range can be assigned to each switching output.
The particular output is switched when the level or temperature enters this range.
The output switches back when leaving the range. The lower switch-back value is
just below the lower switching value (lower switching value minus 1% FS, see section
8.4). The upper switch-back value is just above the upper switching value (upper
switching value plus 1% FS, see section 8.4). The range between the switch value
and the switch-back value forms a safety margin which prevents unwanted switching
operations from being triggered.
Example for switching output 1 (normally open):
Abbreviations: "HI 1" to "HI 4" = High level 1 to 4 = upper switching point 1 to 4
"Lo 1" to "Lo 4" = Low level 1 to 4= lower switching point 1 to 4
FS (full scale) = relative to the complete measuring range
NOTE:
The window function will only operate properly (switch on and off), if all switching
values (including the safety zone) are greater than 0 inch or –9.4 °F (model with
temperature sensor), and are within the unit's nominal measuring range.

8.2 ANALOGUE OUTPUT
The versions with 1 or 2 switching points can have an analogue output as an option.
The output can be switched to either 4 .. 20 mA or 0 .. 10 V (corresponding to measuring
range) via the basic menu and can be assigned to fluid level or to temperature (optional).
The versions with 4 switching points have two 0 .. 10 V analogue outputs.
In this case fluid level and temperature are permanently assigned to an output.
