Connecting the electronic insert FEI58 (NAMUR)
The two-wire connection for a separate switching unit in accordance with NAMUR specifications
(IEC 60947-5-6), e.g. FXN421, FXN422, FTL325N, FTL375N from Hauser.
Change in output signal from high to low current in event of limit detection.
(H-L edge)
Additional function:
Test key on the electronic insert.
Pressing the key breaks the connection to the isolating amplifier.
!
Note!
In the case of Ex-d operation, the additional function can only be used if the housing is not exposed
to an explosive atmosphere.
When connecting to Multiplexer: set 3 s as the cycle time at least.
Power supply
Power consumption: < 6 mW at I < 1 mA; < 38 mW at I = 2.2 to 4 mA
Interface connection data: IEC 60947-5-6
Signal on alarm
Output signal in the event of damage to the sensor: < 1.0 mA
Connectable load
• See the technical data of the connected isolating amplifier as per IEC 60947-5-6 (NAMUR)
• Connection also to isolating amplifiers which have special safety circuits (I > 3.0 mA)
Connect the FEI58 (NAMUR) as follows:
1.
Make the connection as shown in the graphic.
2.
Turn the cable gland until tight.
!
Note!
Do not switch on the supply voltage until you have
familiarized yourself with the device functions as
described on Page 49 "Operation". This will ensure
that you do not accidentally trigger any processes by
switching on the supply voltage.
3.
Switch on the supply voltage.
