    •ANALOG IN MAIN/ALT SELECT RELAY: Select the output relay that is to be used to 
    multiplex two analog input signals to the PQMII. 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: This message allows the user to input a user def ined 20 
    character alphanumeric name for the 
    MAIN and ALT analog inputs. To enter the names, 
    perform the following steps:
    Allow access to setpoints by enabling setpoint access.
    Select the Analog Input name message display under the 
    S2 SYSTEM SETUP 
     ANALOG INPUT setpoints group.
    Use the 
    VA L U E keys to change the blinking character over the cursor. A 
    space is selected like a character.
    Press the 
    ENTER key to store the character and advance the cursor to the 
    next position. To skip over a character press the 
    ENTER key.
    Continue entering characters and spaces until the desired message is 
    displayed. If a character is entered incorrectly, press the 
    ENTER key 
    repeatedly until the cursor returns to the incorrect position and re-enter 
    the character.
    •ANALOG IN MAIN/ALT UNITS: This message allows the user to input a user def ined 10 
    character alphanumeric name for the 
    MAIN and ALT units. To enter the units, perform 
    the same steps as shown for analog input name.
    •MAIN/ALT 4 mA VALUE: This message appears for each analog input and allows the 
    user to assign a numeric value which corresponds to the 4 mA end of the 4 to 20 mA 
    signal range.
    •MAIN/ALT 20 mA VALUE: This message appears for each analog input and allows the 
    user to assign a numeric value which corresponds to the 20 mA end of the 4 to 20 mA 
    signal range.
    •ANALOG IN MAIN/ALT RELAY: Analog input 
    MAIN and ALT detection can either be 
    disabled, used as an alarm or as a process control. Set this setpoint to OFF if the 
    feature is not required. Selecting “Alarm” causes the alarm relay to activate and 
    displays an alarm message whenever a 
    MAIN or ALT analog input condition exists. 
    Selecting an auxiliary relay causes the selected auxiliary relay to activate with no 
    message displayed. This is intended for process control.
    •ANALOG IN MAIN/ALT LEVEL: When the measured 
    MAIN or ALT analog input meets or 
    exceeds the level set by this setpoint , a 
    MAIN or ALT analog input condition will occur.
    •ANALOG IN MAIN/ALT DELAY: If the 
    MAIN or ALT analog input meets or exceeds the 
    ANALOG IN MAIN/ALT LEVEL setpoint value and remains this way for the time delay 
    programmed in this setpoint , an analog input condition will occur. If the 
    ANALOG IN 
    MAIN/ALT RELAY
     setpoint is set to “Alarm”, the alarm relay will activate and the ANALOG 
    IN MAIN/ALT ALARM
     message will be displayed. If the setpoint ANALOG IN MAIN/ALT RELAY 
    is set to “Aux1”, “Aux2”, or “Aux3”, the respective auxiliary relay will activate and no 
    message will be displayed after the delay expires.

    The data logger operation is only conf igurable using the EnerVista PQMII Setup Software. 
    On occasions it may be necessary to stop the data loggers using the PQMII keypad and 
    then a computer to extract the logged information. The 
    STOP DATA LOG 1(2) setpoints allow 
    the user to stop the respective data log. These setpoints also display the current status of 
    the respective data logger. Refer to 7.6 Data Logger Implementation for a detailed 
    implementation description.

    •SAG LEVEL: When the voltage on any phase drops below this level a Sag condition 
    occurs. During this condition, the average voltage and duration of the disturbance are 
    calculated. The condition ends when the level increases to at least 10% of nominal 
    plus pickup of the 
    SAG 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 sag type will be logged. If the duration was greater then 1 
    minute an event with an undervoltage type will be logged when this feature is

    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

    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 shown with relays programmed non-failsafe and control 
    power not applied.
    •Failsafe: The relay coil is energized in its non-active state. Loss of control power will 
    cause the relay to go into its active state. That is, a failsafe alarm relay will cause an 
    alarm on loss of control power. Contact conf iguration is opposite to that shown in the 
    Wiring Diagrams for relays programmed as failsafe when control power is applied.
    5.4.2 Alarm Relay
    PATH: SETPOINTS  S3 OUTPUT RELAYS  ALARM RELAY
    •ALARM OPERATION: The terms ‘failsafe’ and ‘non-failsafe’ are def ined above as 
    implemented in the PQMII. If an alarm is required when the PQMII is not operational 
    due to a loss of control power, select failsafe operation. Otherwise, choose non-
    failsafe.
    •ALARM ACTIVATION: If an alarm indication is required only while an alarm is present , 
    select unlatched. Once the alarm condition disappears, the alarm and associated 
    message automatically clear. To ensure all alarms are acknowledged, select latched. 
    Even if an alarm condition is no longer present , the alarm relay and message can only 
    be cleared by pressing the key or by sending the reset command via the computer.
    5.4.3 Auxiliary Relays
    PATH: SETPOINTS  S3 OUTPUT RELAYS  AUXILIARY RELAY 1(3)
    The PQMII contains three (3) auxiliary relays, denoted as Aux1 through Aux3. The terms 
    ‘failsafe’ and ‘non-failsafe’ are def ined in the previous section.

    							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 conditions 
    are acknowledged, select “Latched”. If the condition is no longer present , the auxiliary 
    relay can be reset by pressing the key or by sending the reset command via the 
    computer.
    NoteThe PQMII uses a priority system to determine which function will control the relays if they 
    happen to be assigned to more than one function.
    The Pulse Output function has the highest activation priority, followed by the Analog Input 
    Main/Alt Select functions. The alarm functions have the lowest priority. For example, if a 
    relay is assigned to an alarm function and also assigned to one of the pulse output 
    parameters, it only responds to the pulse output function.
