3Φ POS REAL ENERGY: This message displays the positive watthours (in kWh) since the TIME OF LAST RESET
date. Real power in the positive direction will add to this accumulated value, and real power in the negative
direction will add to the negative watthour value. The setpoint S1 PQM SETUP \ CLEAR DATA \ CLEAR ENERGY VAL-
UES is used to clear this value. The displayed value rolls over to 0 once the value 4294967295 (FFFFFFFFh)
has been reached.
3Φ NEG REAL ENERGY: This message displays the negative watthours (in kWh) since the TIME OF LAST
RESET date. Real power in the negative direction will add to this accumulated value, and real power in the pos-
itive direction will add to the positive watthour value. The setpoint S1 PQM SETUP \ CLEAR DATA \ CLEAR ENERGY
VALUES is used to clear this value. The displayed value will roll over to 0 once the value 4294967295
(FFFFFFFFh) has been reached.
3Φ POS REACT ENERGY: This message displays the positive varhours (in kvarh) since the TIME OF LAST
RESET date. Reactive power in the positive direction will add to this accumulated value, and reactive power in
the negative direction will add to the negative varhour value. The setpoint S1 PQM SETUP \ CLEAR DATA \ CLEAR
ENERGY VALUES is used to clear this value. The displayed value will roll over to 0 once the value 4294967295
(FFFFFFFFh) has been reached.
3Φ NEG REACT ENERGY: This message displays the negative varhours (in kvarh) since the TIME OF LAST
RESET date. Reactive power in the negative direction will add to this accumulated value, and reactive power in
the positive direction will add to the positive varhour value. The S1 PQM SETUP \ CLEAR DATA \ CLEAR ENERGY VAL-
UES setpoint clears this value. The displayed value will roll over to 0 once the value 4294967295 (FFFFFFFFh)
has been reached.
3Φ APPARENT ENERGY: This message displays the accumulated VAhours (in kVAh) since the TIME OF
LAST RESET date. The setpoint S1 PQM SETUP \ CLEAR DATA \ CLEAR ENERGY VALUES clears this value. The dis-
5
played value will roll over to 0 once the value 4294967295 (FFFFFFFFh) has been reached.
REAL ENERGY LAST 24h: This message displays the accumulated real energy (in kWh) over the last 24-
hour period. The 24-hour period used by the PQM is started when control power is applied. The PQM updates
this value every hour based on the previous 24-hour period. This information will be lost if control power to the
PQM is removed.
REAL ENERGY COST: This message displays the total cost for the real energy accumulated since the TIME OF
LAST RESET date. The setpoint S1 PQM SETUP \ CLEAR DATA \ CLEAR ENERGY VALUES clears this value.
REAL ENERGY COST PER DAY: This message displays the average cost of real energy per day from time of
last reset to the present day. The cost per kWh is entered in the S1 PQM SETUP \ CALCULATION PARAMETERS \
ENERGY COST PER KWH setpoint.
TARIFF PERIOD 1/2/3 COST: These messages display the cost accrued for the three user-definable tariff peri-
ods. The start time and cost per MWh for these tariff periods are entered with the S1 PQM SETUP \ CALCULATION
PARAMETERS \ TARIFF PERIOD 1/2/3 START TIME and the S1 PQM SETUP \ CALCULATION PARAMETERS \ TARIFF PERIOD
1/2/3 COST PER MWH setpoints, respectively.
TARIFF PERIOD 1/2/3 NET ENERGY: These messages display the net energy for the three user-definable
tariff periods. The start time and cost per MWh for these tariff periods are entered with the S1 PQM SETUP \ CAL-
CULATION PARAMETERS \ TARIFF PERIOD 1/2/3 START TIME and the S1 PQM SETUP \ CALCULATION PARAMETERS \ TAR-
IFF PERIOD 1/2/3 COST PER MWH setpoints, respectively.
TIME OF LAST RESET: This message displays the time and date when the energy parameters were last
cleared. The setpoint S1 PQM SETUP \ CLEAR DATA \ CLEAR ENERGY VALUES clears the energy values.
