RESETTING VALUES

CHAPTER 5: OVERVIEW

5.6Resetting Values

Use the reset function if a new value is desired. It is available in two different modes.

1.UNPROTECTED MODE: Allows quick and easy resetting of max/min values.

2.PROTECTED MODE: Prevents unauthorized resetting the max/min and totaled power functions.

Even if the unprotected mode is selected during programming, the KWH and negative

KWH are always in protected mode. The following examples are for the max/min.

Step 1:

a. If not already in the Amps category press AMPS, then PHASE/NEXT until desired phase is indicated.

Step 2:

a. Press MAX/MIN/LIMITS twice to access the min value for Amps A.

Step 3:

a. While the min value is displayed, press PHASE/NEXT to reset it.

The display blanks; a checkmark appears confirming reset.

Repeat this procedure for each value you wish to reset.
