9  Parameter setting

During the parameter setting process the unit remains in the operating mode� 

It continues its monitoring function with the existing parameters until parameter 

setting has been terminated�

9.1  Parameter setting general

Each parameter setting requires 3 steps:

1

Parameter selection

 

► Press [Mode/Enter] until the  

requested parameter is displayed�

 

2

Setting of the parameter value

 

► Press [Set] and keep it pressed�

 

> Current setting value of the parame-

ter flashes for 5 s� 

 

> After 5 s: The setting value is chan-

ged: incremental by pressing briefly 

or scrolling by holding pressed�

 

The numerical values are incremented continuously� If the value is to be reduced: Let 

the display move to the maximum setting value� Then the cycle starts again at the 

minimum setting value�

3

Acknowledgement of the parameter 

value

 

► Press [Mode/Enter] briefly�

 

> The parameter is displayed again� 

The new setting value is stored�

 

Setting of other parameters:

 

► Start again with step 1�

Finishing the parameter setting:

 

► Press [Mode/Enter] several times until the current measured value is displayed or wait 

for 15 s� 

 

> The unit returns to the operating mode�

•  If [SLoc] is displayed when attempting a modification of a parameter value, the 

sensor is locked via software� This locking can only be removed via a parame-

ter setting software�

•  In case of parameter setting with the user interface of the ifm Container pro-

gram, the values can be directly entered in the specified fields�

•  Changing from menu level 1 to menu level 2:
