Icos FA14B02-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
Snubber
Filter
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 Max. Switching Current
110Vac 20VA
220Vac 20VA
5Vdc 2.5W
12Vdc 5W
24Vdc 10W
24Vac: NOT recommended
Term of Warranty
For installations according to this guide:
02 (two) years warranty. Incorrect installation cancels the 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 contactor and K8
*On accessories.icos.us check models and prices of Filters and Mini Contactor
! Never connect the sensor
directly to a motor, pump,
lamp or any other load
over 20W.
Always use a contactor or
relay.

Follow the instructions below to protect and extend the shelf life of the sensor:
AUXILIARY CONTACTOR (mini contactor) mind the distance:
•
Direct connection
to the sensor
SOLENOID VALVE or POWER CONTACTOR:
•
Use mini contactor or auxiliary relay.
ELECTRONIC EQUIPMENT:
•
›
Interface relay/relay coupler: Use 4K7 10W resistor.
›
Timing relay and frequency inverter: Use 220R 5W
AC Current: Use K8 Filter
DC Current: Use KD Filter

? 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:
22R 5W
This resistor dampens the peak voltage caused by the
capacitance of cables and electronic equipment input.
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.
