Functioning Of The Connector Pins 2 And 4 - IFM efector500 PP70 Série Notice Utilisateur

Functioning of the connector pins 2 and 4

The functions of the connector pins 2 and 4 are variable and can
be set by means of a programming unit.
• Pin 2 = Teach input or switching output (can be set by menu com-
mand OU2; → page 28).
• Pin 4 = switching output or communication interface (can be set by
menu command OU1 → page 28).
Setting
OU2 = tch
(when delivered)
OU2 = Hno, Hnc, Fno
or Fnc
Setting
OU1 = EPS*
OU1 = Hno, Hnc, Fno
or Fnc
(Hno when delivered)
* This setting should be selected when the programming/display unit is
permanently connected to the sensor.
Pin 2
Pin 2 is Teach input.
A Teach signal at pin 2 defines the current
measured value as switching threshold and
sets pin 4 as switching output.
Pin 2 is switching output.
Switch-on and switch-off points are programmed.
The Teach function is deactivated.
Pin 4
Pin 4 is communication interface.
The sensor expects an EPS protocol of a
programming / display unit. The switching
function is not active.
Pin 4 automatically becomes the switching output
when the sensor receives a valid Teach signal.
Pin 4 is switching output.
Switch-on and switch-off points are programmed.
When the sensor is connected to a
programming/display unit pin 4 becomes
communication interface (transfers measurement
and evaluation signals, receives programming
When the programming/display unit is
disconnected, pin 4 automatically becomes
the switching output again.
