ASM 400 

 

3.8 Testing the signal and the displayed value 

After assembling the transmitter, you should in any case perform a test of the displayed value 
and the switching functions. Therefore, the device must be connected according to the specifi-
cations. In the next step, you should carry out the settings at the zero point (menu 3) and end 
point  (menu  4),  as  well  as  the  decimal  point  (menu  2).  The  displayed  value  of  the  ASM  400 
should correspond to the respective measuring value of the transmitter. 

3.9 Final inspection of the device 

For final inspection, it is essential to test the displayed value as well as the switching function 
again. The switching function may be externally tested by a  variety of procedures. The use of 
two  external  LEDs,  which  are  triggered  through  protective  resistors,  is  the  simplest  and  most 
suitable way. 

4. Operation 

4.1 Operating and display elements 

Fig. 3 Touchpad 

The device has a green LED for displaying the active contact of set point 1 and a yellow LED for 
displaying the active contact of set point 2. The LEDs will light up when the respective set point 
has been reached and the contact is active. 

The  display  of  the  measured  value  as  well  as  the  configuration  of  the  individual  parameters  
occur through a menu via a 4-digit seven-segment display. The individual functions can be set 
with the help of two miniature push buttons located in the front.

the menu items and set values 

   

When setting the values, you can increase the counting speed by pushing the respective
