5.3.2  Limit Monitoring  

 
One alarm output for excess and one alarm output for insufficient temperature have been pre-configured. They 
were  set at 

±  1  [°C]

  from  the  currently  set desired  value  (

SP1

).  In  order  to prevent malfunctions  from  broken 

cables,  a  permanent  signal  is  transferred  to the  superordinate  control  unit.  If  the  preset value  at the WTR  is 
exceeded or fallen short by 1°C, the individual alarm output drops as a signal for the superordinate control unit 
(Signal at LOW). The alarm signal is turned off (Signal at HIGH) once the set value range has been reached 
again. If the currently measured, actual temperature is within the preset tolerance range of ± 1 [°C], HIGH will 
be indicated for both alarm outputs.  
The hysteresis (HySt) for error signal is factory-set at ±1 [°C] symmetrically to the limit value of the insufficient 
temperature (UT) or excess temperature (OT). If the temperature rises or falls back into these limits, the respec-
tive signal will be given. Please refer to 

Figure 5

 for the signal curves of the two alarm outlets of the WTR-x. 

 

Signal at alarm output 1 

 
Used  for  issuing  an  error  signal 
for insufficient temperature (devi-
ation AL -1°C to set value SP1) 

 

Signal at alarm output 2 

 
Used  for  issuing  an  error  signal 
for excess temperature (deviation 
AL +1°C to set value SP1)
