eicos FC34B02-M12 Manual

Operation

• Liquids with solid particles and/or fouling require prior testing. Use
filter before the Sensor to prevent the internal piston from locking. Not
recommended for industrial water waste.
• Liquids with ferrous and/or magnetic particles require technical
analysis: the Sensor contains magnetic components inside. Use a
magnetic filter before the Sensor to avoid deposition/settling that will
prejudice its operation.

Typical Connection to Contactor

K8 for AC
Snubber
KD for DC
Installing the snubber filter extends the
lifespan of the sensor's electrical contact.
The sensors work in all voltage and current ranges displayed in the table bellow:
Operating Voltage Max. Switching Power
110Vac 20VA
220Vac 20VA
5Vdc 2,5W
12Vdc 5W
24Vdc 10W
24Vac: NOT recommended
Term of Warranty
For installations according to this guide:
Incorrect installation cancels the warranty.
02 (two) years warranty.
All Sensors have been tested and approved during the manufacture process.

Electrical Contact of Sensors - Attention to Install

Reed Switch 20W/VA: Protect the Electrical Contact of your Sensor
Reed Switches are hermetically sealed contacts
actuated by a magnetic field.
The life expectancy of a reed switch refers to a
kind of load to be used. Reed Switches of the highest reliability are applied in
our sensors, and their life expectancy can reach above two million operations.
However, when they are switching lamps, inductive or capacitive loads, this
number may decrease.
Switching Power
It is important to consider that the power specified by an electrical load is
often referred to the permanent working state.
For higher power, use an auxiliary relay or contactor as recommended below,
or similar.
Siemens 3RT1015 Contactor
Initial: 31.7VA
Rated: 5.1VA
Note: Reed Switches have reached over one million operations in tests with

! Never connect the
sensor directly to a motor,
pump, lamp or any other
load over 20W.
Always use a contactor
or relay.

? Risk of failure (welding of the Reed Switch Contact) due to CAPACITANCE, which
can occur depending on the distance and cable used in the connection to the contactor.
• Connecting the sensor to a contactor in long distances, use resistor:
Important: For distances greater than 40m, use 24Vdc voltage.
• Connecting the sensor to an electronic equipment:
Important: For installation with relay coupler, use 4K7 10W resistor.
