Honeywell VRX180 Manual De Usuario

Counts the number of OFF(0)-to-ON(1) transitions of the input.  This number is output as CVn 
OV.  When this number reaches the Preset value, a discrete output parameter CVn OS goes 
ON(1) until Reset occurs. 

Table 4-21 describes the Counter prompts. See Table 4-2 for additional prompts. 

RANGE LOW 

RANGE HIGH 

OFF or number 

Enter the output's trend display limits. Output is not clamped 
or flashed when it exceeds these limits. 

INPUT

1 

Input source. 

RESET 

OFF, discrete parameter, 0, 
1 

When Reset is level high, output state (OS) is ON and the 
counter resets to zero if counting up or to the Preset value if 
counting down from it.  When Reset is level low, counter 
resumes counting. 

PRESET 

OFF, analog parameter, 
number 

The number of input transitions after which the CVn OS 
output will go ON(1).  To count forever, set to OFF.  If OFF, 
CVn OS will not be triggered. 

COUNT DOWN 

YES or NO 

Select NO to count up from zero to the Preset value; YES to 
count down from the Preset value to zero.  If Preset is OFF, 
Count Down must be NO.
