Analog  inputs  1,  2,  3,  8  and  9  has  separate  set  points  for  two  levels  alarm  setting  and  delay  for 
activation of alarm.  
Analog input 4, 5, 6 and 7 has special „window“ protection. It is possible to adjust Low and High level 
with alarm setting Wrn and Sd for each of level. Two delay setpoints are adjustable for Low and High 
level. (See Practical example below)  
Window protection is necessary to adjust in Modify->Alarm properties->Direction. 
Analog input alarm levels and delay adjust in Engine protect group of Setpoints. 
 
HINT 
In Alarm list and History is displayed only Wrn and Sd for matching analog input. There isnt visible 
direction of protection Low or High. 
 
Practical example of - Class C - Window protection : 
Pressure  sensor  is  configured  on  the  analog  input  7  and  is  placed  on  the  intake  pipe.  There  are 
needed  two  level protection.  Low level protection  against  suction  from  the  tank without  liquid,  that 
could destroy  pump. High level protection against high liquid pressure in pipe, which could destroy 
filters against impurity installed between tank and pump. 
 
AIN7 LowWrn  = 2bar 
AIN7 LowSd    = 1bar 
AIN7 LowDel = 5s 
AIN7 HighWrn = 4bar 
AIN7 HighSd = 5bar 
AIN7 HighDel = 2s 
 
HINT 
Class C protection is working and LowWrn, LowSd, LowDel, HiWrn, HiSd, HiDel  setpoints are visible 
only when corresponding AIN is configured in Modify->Alarm properties-> Direction-> Window prot.
