Page 9: Important Safety Notes
(earthing screw M3 and toothed washer M3 included) 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. -
Page 10: Starting Up
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 "... -

Page 13: Output Function
ENS 3000 Page13 Output function 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. -
Page 14: Analogue Output
ENS 3000 Page14 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). -
