How to covert from a legacy CUB4V unit to the current CUB5V

PLEASE NOTE:

When converting from the legacy CUB4V unit to the current CUB5V there is a input signal range jumper under the rear cover that will need to be set for your application's   Vdc input level.  See page 3 of CUB5V product manual. Display scaling is also done via the front keypad not with scale potentiometers.

IN THIS ARTICLE

• Wiring conversion from CUB4V to CUB5V panel meter.
• Optional program lockout function.
• Example unit scaling procedure. 
• Style applied input scaling method. 

To complete the conversion of the legacy CUB4V unit to current CUB5V units proceed as below.

1. First if this application was using an input signal less than 20Vdc. Remove the rear cover of the CUB5V unit and set the input range jumper to the 2 Vdc position. Reference CUB5V product manual document page 3 for details.
2. Connect the signal + wire to the input terminal of the CUB5V unit.
3. Connect the signal – wire to the common terminal of the CUB5V unit.
4. Connect your power supply V+ wire to the +9-28 Vdc terminal of the CUB5V unit.

Optional program lockout function 

There is a program disable mode available in the CUB5V unit. This can be programmed by entering menu 1-INP, under parameter USR IN, and set as PLOC function. Then add a jumper across rear terminals USR COM and USR to activate. This is optional if a program disable feature is desired.

Example unit input scaling procedure

End user has a transducer with a 0-10 Vdc output and wants the display scale to read PSI.  Pressure range of the transducer is 0-1000 PSI. 

Unlike the legacy CUB4V unit the CUB5V scales the input via firmware settings. Please see Page 7 of the CUB5V product manual.  Menu 1-INP 

Given the above example you would prog ram as follows. 

• RANGE 20 U 
• DECPT  0
• OFSET  0
• FILTR    1
• BAND  10
• STYLE  KEY
• INP1   0.00
• DSP1   0
• INP2   20.00
• DSP2   1000

The above example was scaled using the STYLE KEY method. The end user knows the input signal type as well as the transducer range.  If the signal type is known but not the range of the transducer.  The CUB5V can be scaled using the active input signal level and then scaled to a known reference value using the STYLE APLY method. Please see page 7 of the CUB5V product manual.
