How to convert the Float 32 Format to decimal.

End User needs to convert a Float 32 register value into a decimal number

ION and Powerlogic Meters

Arithmetic Conversion

Some registers are stored as Float 32 values. In order to make sense of that value we have to convert that number to a decimal value.

Float 32 values will take 2 registers, if you check in the Register List. 
  1. So, to start with convert the values separately in both the registers to Hexadecimal. 
  2. Now, use the below link and use the value in the registers in ascending next to each ​​​​​​

Below is an example of the process:

For Registers,
3000 - 5EF3
3001 - 4323

Input the hexadecimal box of the link as 0X5EF34323 to get the exact decimal values. 8.7644463E18

Video: How to set up and test ground fault alarm in Micrologic P and H trip units for PowerPact P and R and Masterpact NT and NW breakers

Configuring & Testing Ground Fault Alarm on Micrologic P & H Trip Units

Product Line:
P and H trip units for PowerPact P, R and Masterpact NT, NW
FFTK (S33595)
M2CTEST adapter

Mainly intended for 5.0P and 5.0H trip units, no Ground Fault trip function, Ground Fault alarm only.
However, this procedure will also work for 6.0P and 6.0H trip units that also have Ground Fault trip feature.
Programmable contacts (M2C or M6C) must also be installed.
No other trip unit types are included in this article.

The trip unit instruction by itself may not be clear on the exact sequence to program ground fault alarm.
Also a procedure is needed to test ground fault alarm without doing primary injection.

Setting up the ground fault alarm on a Micrologic 5.0P or 5.0H trip unit is a 3 step process. First, you turn on the ground fault alarm and set the pickup/drop out levels. Then you assign the ground fault alarm to an M2C or M6C contact. Finally you set up the alarm mode to a non-latching contact. For more deatiled instructions, reference Micrologic 5.0P instruction bulletin 48049-137-05 or see the video below.

Ground Fault Alarm test without using primary injection, using the full function test kit S33595 and the M2CTEST special tool adapter for the full function test kit:
Use the attached EAV34309 instructions for this testing procedure, general information, precautions, and proper connection.

Why choose Type B RCD for 3 Phase Variable Speed Drives?

For the 3 Phase Variable Speed Drives, the RCD type B or type B-Si is particularly suitable.
It protects against fault currents with DC offset, which is true for three-phase power converters. In addition, it has enhanced immunity against nuisance tripping caused by:

  • EMC common mode filters connected upstream VSD.
    Type B has a tripping delay allowing the inrush current to flow on power up.

  • The permanent switching leakage currents existing in power converters (ex: 25kHz).
    Type B include a "low pass" filter to ensure a trigger threshold which increases with frequency while complying with the personal protection curve (fibrillation).

Please note: if the required sensitivity is 300mA, Selective type RCD should be proposed ensuring a non-triggering time of 50ms. 

More information can be found on the Earth Fault Protection guide: https://download.schneider-electric.com/files?p_enDocType=Catalog&p_File_Name=CA908066E+%28web%29.pdf&p_Doc_Ref=CA908066E

With regards to installation of these RCDs, they are mounted upstream of the Variable Speed Drives.

See below example


Schneider Electric offers Acti9 iID range of 4 Pole RCDs type B available in 30 mA sensitivity and type B-Si available in 30 and 300 mA sensitivity (Selective type is available)
