Dimension 22.5 x 75 x 100 mm
Housing IP40, mounting DIN rail 35x7.5 mm (EN50022); Option: IP55 wall-mount cabinet 88x150x130mm
Cable min. Wire cross-section 0.5mm², shielded cable
Electrical connections IP20, screw terminals, cable cross-section max 2.5 mm²
Signalling 1x LED: ''Operating''
1x LED: ''Status of relay''
EC Conformity: The instrument meets the legal requirements of the current European Directives.
OPERATING RANGE
The capacitive resistance of long cables reduces the sensitivity of the detection.
A standard 3-wire PVC cable has a capacitance of 100 pF/m
The range therefore depends on the liquid resistance and on the cable length between the electrode and the relay ES2001.
This results in an operating range according to the diagram below:

RECOMMENDATIONS FOR THE CABLE
- Use a multi-core cable of 0.5 mm².
- This cable must be separated from other cables.
- Above 25 m length, it is necessary to use a shielded cable.
SETTINGS
The transparent front panel can be removed by levering it out, gently, with a screwdriver.
Sensitivity Potentiometer P1 and DIP S2
To adaptat the sensitivity to the liquid conductivity.
Note The poorer the liquid conductivity and greater the distance between electrodes, the higher the response
sensitivity must be set.
Caution An excessive sensitivity leads to faulty triggering.
Open / Closed current loop DIP S1
Delay Potentiometer P2: To prevent multiple switching with waves on the liquid surface.
Potentiometer Anticlockwise Right stop
P1 Sensitivity Minimum Maximum
P2 Delay approx. 0.5 seconds approx. 3 seconds
DIP switch ON OFF
1 Current in the loop No current
2 High sensitivity 5 to 150 kΩ Low sensitivity 1 to 70 kΩ

Overflow alarm (0-signal):
Alarm signalling relay K1 drops off when MAX electrode immerses or in the case of malfunction/voltage failure of the electrode control system
Overflow alarm (1-signal):
Alarm signalling relay K1 activates when MAX electrode immerses or in case of malfunction/voltage failure of the electrode control
---> Connect relay K1 to terminal 12
TESTING THE RELAY:
- Disconnect the electrodes from the relay ES2001
- Short circuit E0 and E2 → the relay is activated (alarm function)
- Short circuit in the order E0, E2 and E1 → Enable E2 then E1 (control function)
