NOVUS AUTOMATION 

6/7 

A(all

 

Minimum weight automatic calibration

  –  This 

parameter defines the value to be displayed when the 

minimum reference weight is applied. See the section 

Performing Auto Calibration.  

A(alk

 

Maximum weight automatic calibration 

 

This 

parameter defines the value to be displayed when the 

maximum reference weight is applied. See the section 

Performing Auto Calibration. 

Table 5

 shows the sequence of levels and parameters presented in the indicator display. There are parameters that must be defined for each alarm 

available.

PROBLEMS WITH THE INDICATOR 

Connection errors or improper configuration will result in 

malfunctioning of the indicator. A final review can avoid wasting time 

and losses. 
The indicator  some error messages will help the user identify 

possible problems. 

MESSAGE 

PROBLEM DESCRIPTION 

VVVVV 

Measured value is above the value allowed for the 

selected sensor or signal limit.  

nnnnn 

Measured value is below the value allowed for the 

selected sensor or signal limit. 

----- 

Open input. No signal. 

Other error messages shown by the indicator must be reported to the 

manufacturer. Inform the serial number if this should occur. The serial 

number can be viewed at the display by pressing the 

 

key for 

about 3 seconds. 
The software version of the instrument can be viewed at the time the 

unit is powered. 
When not properly configured, the instrument may show false error 

messages, particularly those related to the type of input selected. 

SPECIAL RECOMMENDATIONS 

Should the indicator be repaired, some special handling care should 

be taken. The device must be withdrawn from  the case and 

immediately placed in an anti-static wrap; protected from excessive 

heat and humidity. 

INPUT CALIBRATION 

An appropriate framework should be available for calibration of 

equipment capable of providing the electrical signals needed with the 

required accuracy. 
When recalibration of some type of input is required, proceed as 

described below. 

a)

  Set the indicator for the input type to be calibrated, see 

Table 1

b)

  Program the desired upper and lower display limits (

in.lol

 and 

in.kil

) with limits on the type of configured input, see 

Table 1

c)

  Access the parameter “

inLo(

” and applied to input a signal 

corresponding to a known value and slightly above of the lower 

limit. 

d)

  Set the indicated value using the keys 

 and 

 to adjust 

the expected value for the applied signal. 

e)

  Access the parameter “

inki(

” and applied to input a signal 

corresponding to a known value and slightly below of the upper 

limit. 

f)

  Set the indicated value using the keys 

 and 

 to adjust 

the expected value for the applied signal. 

g)

  Exit the calibration cycle and verify that the calibration became 

adequate. Repeat c to f until no new adjustment is necessary. 

AUTOMATIC CALIBRATION 

To perform automatic calibration, the system must already be 

installed and configured with the input  type and range already 

defined. 

a)

  Access the Auto Calibration cycle and the parameter 

A(all”

b)

  Put on the load cell the minimum reference weight and wait to 

stabilize. 

c)

  Adjust the parameter 

A(all”

 to display the desired value. 

d)

  Press the 

P

  button to save this value and advance to the 

parameter 

A(alk

e)

  Put on the load cell the maximum reference weight and wait to 

stabilize. 

f)

  Adjust the parameter 

A(alk

 to display the desired value. 

g) 

Press 

P

 to save this value and terminate the procedure. At this 

time the indicator will show the weight on the load cell.
