5.2 A1 DATA 5.2.1 DESCRIPTION

This page contains the real-time data as measured by the MM2. Actual Values Page 1 is divided into

three sections, MOTOR DATA, PROCESS DATA, and PROGRAMMABLE MESSAGE.

5.2.2 MOTOR DATA

PATH: ACTUAL VALUES

A1: DATA

MOTOR DATA

MOTOR

STATUS:

This message indicates the name and status of the motor. The top line

of the display (20 characters) can be programmed to a user defined

alphanumeric name. The second line indicates motor status. The fol-

lowing list shows the possible motor status indications:

•

Unavailable

: There is at least one condition present that is prevent-

ing start commands from operating. Possible conditions are: a trip is

present, the STOP key is being pressed, the Stop Switch input is

open, one of the Process Interlock switches is open, an undervolt-

age delayed restart is in progress, an Autotransformer Start Inhibit

is in progress, or the STARTER TYPE setpoint is OFF.

•

Available-Auto

: Start commands from the serial port or the Auto

Start A / Auto Start B interlock switch inputs will be performed. Start

commands from the Start A / Start B switch inputs and the START

A/ START B keys will be ignored.

•

Available-Manual

: Start commands from the Start A / Start B switch

inputs and/or the START A/ START B keys will be performed. Start

commands from the serial port and Auto Start A / Auto Start B

switch inputs will be ignored.

•

Running

: At least one contactor output relay is closed.

A= 74 B= 74

C= 74 AMPS

This message displays the actual RMS current in each phase in amps.

Format: 10.0 at CT Primary

≤

50 A; 100 at CT Primary

50 A.

GROUND CURRENT =

2.4 AMPS

This message displays the ground fault leakage current flowing from

any phase to ground in amps.

MOTOR LOAD =

74% FULL LOAD

This message displays the motor load as a percentage of full load cur-

rent (FLC). The motor load is calculated as the average of the three

motor phase currents. When the value exceeds 100%, an overload con-

dition exists. The MM2 eventually trips if the current is not reduced

below 100% of FLC

SERVICE FACTOR.
