Similar Hi Alarms will occur for other voltage parameters will be displayed here. If no VT connection type is programmed for the S2 SYSTEM SETUP \ VOLTAGE SENSING \ VT CONNECTION TYPE setpoint, the following flash message will appear when an attempt is made to enter this group of messages. 5.3.4 SPEED If the Tachometer function is assigned to one of the digital inputs, the tachometer readout may be viewed here. If no digital input is configured as tachometer in S3 DIGITAL INPUTS \ ASSIGNABLE INPUT1/2/3/4, the following flash message will appear when an attempt is made to enter this group of messages. ?

Watthours and varhours can also be seen here. An induction motor by convention consumes Watts and vars (+Watts and +vars). A synchronous motor can generate vars (–vars) and feed them back to the power system. If the S2 SYSTEM SETUP \ VOLTAGE SENSING \ VOLTAGE TRANSFORMER RATIO setpoint is not programmed, the following flash message appears when an attempt is made to enter this group of messages. Real Power (hp) is converted directly from Real Power (kW). This display-only value is not used for protection functions. This message will not display more than 65535 hp regardless of the actual kW that are being metered. 5.3.6 TORQUE ALARM MESSAGE This message appears in the Alarm Status Event Record (if power (+Watts and +vars). reflects Analog Input Name as programmed ANALOG 3-4 0 Percent Range: –5100 to 4900% Message seen only if Analog In Diff 3-4 set to %Diff Message reflects Analog Input Name as programmed ANALOG 3-4 0 Units Range: –100000 to 100000 Message seen only if Analog In Diff 3-4 set to Abs Diff Message reflects Analog Input Name as programmed THIS FEATURE NOT PROGRAMMED ENTER ESCAPE e e MESSAGE ESCAPE MESSAGE ESCAPE MESSAGE ESCAPE MESSAGE ESCAPE MESSAGE ESCAPE MESSAGE ESCAPE MESSAGE ESCAPE GE Power Management 469 Motor Management Relay 5-15 5 ACTUAL VALUES 5.3 A2 METERING DATA 5 5.3.9 PHASORS To aid in wiring, the tables on the following page can be used to determine if VTs and CTs are on the correct phases and that their polarity is correct. Problems arising from incorrect wiring are extremely high unbalance levels (CTs) or erroneous power readings (CTs and VTs) or phase reversal trips (VTs). To correct wiring, simply start the motor and record the phasors. Using the tables below along with recorded phasors, system rotation, VT connection type, and motor power factor the correct phasors can be determined. Note that the phase angle for Va (Vab if delta) is always
