CHAPTER 5: SETPOINTS PQMII POWER QUALITY METER – INSTRUCTION MANUAL5–25 When the Analog Output parameter is set to “Serial Control”, the analog output(s) reflect a value in proportion to the serial value written to a specif ic register within the PQMII memory map. The locations are as described in the table below. 5.3.3 Analog Input PATH: SETPOINTS S2 SYSTEM SETUP ANALOG INPUT Analog Output Modbus Register Register Analog Output 1 Analog Output 1 Serial Value 1067 Analog Output 2 Analog Output 2...

If this setpoint is “Off ”, the MAIN analog input setpoints will be used unless a switch input assigned to SELECT ANALOG INPUT is activated. For more information on multiplexing two analog inputs using one of the PQMII output relays, refer to 2.2.8 Switch Inputs (Optional). •ANALOG IN MAIN/ALT NAME:...

They are positive kWh, negative kWh, positive kvarh, negative kvarh, and kVAh. Enter the desired relay to which each parameter is assigned. Select “Off ” if a particular output parameter is not required. •KWh / kvarh / kVAh PULSE OUTPUT...

If a character is entered incorrectly, press the ENTER key repeatedly until the cursor returns to the incorrect position and re-enter the character. •PULSE INPUT 1(4) VALUE: Enter a value in this setpoint that will be equivalent to 1 pulse input on the switch input assigned to Pulse Input 1(4); i.e., 1 pulse = 100 kWh. The accumulated value is...

CHAPTER 5: SETPOINTS PQMII POWER QUALITY METER – INSTRUCTION MANUAL5–31 disturbance are calculated. To end a Swell condition the level must decrease to pickup minus 10% of nominal of the SWELL LEVEL setting. This hysteresis is implemented to avoid nuisance alarms due to voltage fluctuations. If the duration logged was less then or equal to 1 minute an event with a swell type will be logged. If the duration was greater then 1 minute an event with an overvoltage type will be logged when this feature...

5–32PQMII POWER QUALITY METER – INSTRUCTION MANUAL CHAPTER 5: SETPOINTS 5.4 S3 Output Relays 5.4.1 Description Output relay operation in the PQMII occurs in either ‘failsafe’ or ‘non-failsafe’ modes, as def ined below: •Non-failsafe: The relay coil is not energized in its non-active state. Loss of control power will cause the relay to remain in the non-active state. That is, a non-failsafe alarm relay will not cause an alarm on loss of control power. Contact conf iguration in the Wiring Diagrams is...

CHAPTER 5: SETPOINTS PQMII POWER QUALITY METER – INSTRUCTION MANUAL5–33 •AUXILIARY 1(3) OPERATION: If an output is required when the PQMII is not operational due to a loss of control power, select failsafe auxiliary operation, otherwise, choose non-failsafe. •AUXILIARY 1(3) ACTIVATION: If an auxiliary relay output is only required while the selected conditions are present , select “Unlatched”. Once the selected condition disappears, the auxiliary relay returns to the non-active state. To ensure all...
