Honeywell VRX180 Manuale Utente

Selects one of 48 inputs based on the action and outputs it as CVn OV. 

Table 4-18 describes the Signal Select prompts.  See Table 4-2 for additional prompts. 

OUTPUT LOW LIMIT 

OUTPUT HIGH LIMIT 

OFF or number 

Displayed output value will be clamped and will flash when 
these limits are exceeded. 

INPUT #1 - INPUT #48 

OFF, analog parameter, 
number 

Up to 48 input sources to be selected from according to the 
ACTION. 

ACTION 

HIGH 

Selects the highest value input. 

 

LOW 

Selects the lowest value input. 

 

AVG 

Averages the input values. 

 

MIDDLE 

Selects the middle (median) input value. If the number of 
inputs is even, selects the sum of the middle two input values 
divided by 2. 

 

F-GOOD 

(First Good) If inputs fail, selects the first good input to the 

function block.  For example, if inputs 1 and 2 fail, then input 
3 is selected. 

 

ANA-SW 

(Analog Switch) Selects an input equal to the value of the 
ANALOG SELECT parameter. 

 

DIS-SW 

(Discrete Switch) Selects Input #1 or #2 according to state of 
DISCRETE SELECT. 

ANALOG SELECT 

OFF, analog parameter, 
number 

Example: if ASEL=3, then Input #3 is selected. If ANALOG 
SELECT < 1, Input #1 is selected. The value of ANALOG 
SELECT is truncated to a whole number.  For example, if 
ANALOG SELECT is 3.55, the value is truncated to 3 and 
Input #3 is selected. 

DISCRETE SELECT 

OFF, discrete parameter, 
0, 1 

Selects Input #1 when DISCRETE SELECT is off (0); selects 
Input #2 when DISCRETE SELECT is ON (1).  Inputs 3-48 
are unused.
