Issue:
 
Will NSX breaker trip if acknowledge Isd Alarm on Micrologic trip unit when the breaker is ON (Service)
 
Product Line:
 
ComPacT NSX new generation
 
Environment:
 
NSX
 
Resolution:
 
Yes, reset the fault or acknowledge Alarm will not cause a C/B tripping.

However, customer should follow the Responding to a Trip and maintenance recommended for different trip condition mentioned in NSX User guide, page 191/216 on the NSX User guide as on this FAQ published date.
 

Potential issues caused by having >2A limit are:

Damage to the C-Bus cat-5 cable if a dead short were to occur
Impedance causing unstable communications
Potential stressing of power supply units

The C-Bus Cat-5 (cable) must not carry current in excess of 2 A (this is the Maximum C-Bus Current per Network).

Either reduce the number of C-Bus power supply or split the network by using a network bridge(5500NB) in this case.

Issue:
Why is the display blank on the trip unit?

Product Line:
Powerpact P frame, Powerpact R Frame, Masterpact NT, Masterpact NW

Resolution:
The LCD display on a Micrologic P or H trip unit will be blank unless the trip unit is energized.  Energization requires one of the following sets of conditions:

1. The trip unit is energized by an external 24 Vdc applied to terminals F1-F2 (F1 negative-F2 positive).  See attachment for location of terminals.
2. The trip unit is energized by an FFTK or HHTK test kit
3. There is at least 100 V between two phases, AND the load reaches approximately 20% of the breaker's rated current.

• Note that the display will not power up with primary injection testing unless one of the conditions in bullet 1 above is met.
• Note that Ammeter trip units do not require external power and the display will come on with sufficient current flow alone.

See the following bulletins for more information on these trip units.

BCPM Modbus Register List
https://www.se.com/ww/en/faqs/FA212184/

Please see below details given in the BCPM User Guide.




Based on this depending on where your CT strips are connected, you need to read the Modbus registers.

For example, if the DIP switch is set up as above to reflect address 40. Then you read the data for the 42 channels connected to Panel 1 using the Modbus address 40 and the given registers in the Modbus register map.

Then for the other channels connected to Panel 2, you need to use Modbus address 40+1=41.

For example, if you read register 1336 with address 40, that means it gives the current value of channel 1 in the Panel 1.

Then if you read the same register 1336 with address 41, that means it gives the current values of channel 1 in the Panel 2 and so on.

This means if the CTs from 43-63 are connected to Panel 2, if you need the current reading for CT 43, you will need to use +1 Modbus address to read it and use 1336 register and so on.



This is what is explained in the below section in the Modbus map.

Issue:
Maximum motor distance for an Altivar 212.

Product Line:
ATV212

Environment:
All serial numbers for ATV212

Cause:
N/A

Resolution:
The maximum motor cable length is 50m (164ft).  This maximum can be increased with the use of a motor choke.
