Honeywell VRX180 Manual De Usuario

Data Entry lets you enter or revise data online.  Choices available depend on installed options and 
enabled features (see “Enable Features” in Section 4.19). 

Select this item to display a list of alarms and their setpoints.  If the setpoint is a numeric value, it can be 
changed on this display using the Up Arrow, Down Arrow and Left Arrow buttons.  If it is programmed as 
a parameter, it cannot be changed here. 

Select this item to display or change a list of all constants in the instrument.  To change a value, use the 
Up Arrow, Down Arrow and Left Arrow buttons. 

Select either of these items to display or force the status of any discrete. 

The STATE indicates ON or OFF.  FORCE/RELEASE indicates if the discrete is forced or released 
(unforced).  To force a discrete, select FORCE ON or FORCE OFF.  To release a forced discrete, select 
RELEASE.  Adjust with Up Arrow and Down Arrow.  Press Enter  to enter the changes.  Press Menu to 
leave the menu. 

If the AI point has been configured with a pyrometer range, the Input Adjust is applied as a multiplier 
(equal to the newly entered value divided by the actual measured valued at the time that the adjustment 
is entered).  In this case, the Value Adjust is referred to as an “emissivity” adjustment.  If the AI point 
has been configured with any other range, the value adjust is applied as a bias (equal to the newly 
entered value minus the actual measured value at the time that the adjustment is entered). 

All points on the display which are currently adjusted will have a Value Adjust Indicator (*) beside the 
value. 

To adjust a value, select the desired AI and press Enter. Press Enter to highlight the value then use the 
Up Arrow, Down Arrow and Enter buttons to change the value on the display.  The value can be 
changed to any value within the programmed limits of the AI. 

To remove the value adjustment, set the value to OFF.  The AI will display its current value and the 
indicator (*) will be removed. 

This menu item will appear if the optional analog outputs are installed.  It lets you adjust various analog 
output parameters. 

Two output types are available: current output (CAT) and time proportion/duration adjusting (DAT). 

Enter a value of 0 to 100% or an analog parameter for the initial output.  This is the initial output on “cold 
start”.  If the failsafe value is set to off, the output will go to 0. 

For DAT outputs, use the Up Arrow, Down Arrow and Enter buttons to adjust the impulse time.  Impulse 
time must be 

≥

 1 second.  Impulse time is the cycle time for on and off cycling of the output.  For 

example, an impulse time of 150 seconds will cause the output to be on for 75 seconds and off for 75 
seconds when the input source is at 50.
