How to change the power sign on 5.2E, 6.2E, 5.3E,6.3E trip units for Powerpact H, J and L frame breaker?

Issue:
How to change the power sign on 5.2E, 6.2E, 5.3E,6.3E trip units for Powerpact H, J and L frame breaker?

Product Line:
Powerpact H, J and L

Environment:
5.2E, 6.2E, 5.3E,6.3E Micrologic trip units

Cause:
Power values reading negative.



Resolution:
The power sign can be changed through Modbus register, or with RSU software and UTA test kit STRV00910.

RSU:
Modify the Power sign using the RSU software and UTA Tester STRV00910, see link for free RSU download.

By default, the Micrologic E trip unit signs as positive the powers running through the circuit breaker supplied from the top with loads connected from the underside. Circuit breakers powered from the underside must have the powers signed as negative. 

In the Metering setup/Power sign window, select the power sign:
• + The power running through the circuit breaker from top to bottom is
counted positively.
• - The power running through the circuit breaker from bottom to top is
counted negatively.
The default value of the powersign is +.


MODBUS:
Power Flow
Sign 3316 3315 RW — — UINT 0–1 E
Power flow sign
0 = the active power flows from upstream (top) to downstream (bottom) (default).
1 = the active power flows from downstream (bottom) to upstream (top).
The power flow sign command (command code = 47240) configures the content of the power flow sign register.
