    2) For power connections use No 16 AWG

    or larger wires rated for at last 75 °C.

    3) Use cupper conductors only.

    4) Don’t run input wires with power cables.

    All relay contacts are protected by varistor against

    inductive load with inductive component up to 0.5 A.

    The following recommendations avoid serious

    problems which may occur, when relay outputs

    are used with inductive loads.

    High voltage transients may occur switching

    inductive loads.

    Through the internal contacts these transients

    may introduce disturbances which can affect the

    performance of the instrument.

    For all the outputs, the internal protection

    (varistor) assures a correct protection up to 0.5 A

    of inductive component.

    The same problem may occurs when a switch is

    used in series with the internal contacts as shown

    in Fig. 9.

    Fig. 9 EXTERNAL SWITCH IN SERIES WITH

    THE INTERNAL CONTACT

    In this case it is recommended to install an

    additional RC network across the external contact

    as show in Fig. 9

    The value of capacitor (C) and resistor (R) are

    shown in the following table.

    The cable involved in relay output wiring must be

    as far away as possible from input or communica-

    tion cables.

    When fuse is damaged, it is advisable to verify

    the power supply circuit, so that it is necessary to

    send back the instrument to your supplier.

    7) Safety requirements for permanently

    connected equipment:

    - Include a switch or circuit-breaker in the

    installation.

    - Place the switch in close proximity to the

    equipment and within easy reach of the

    operator.

    - Mark the switch as the disconnecting

    device for the equipment.

    NOTE:

    A single switch or circuit-breaker can

    drive more than one instrument.

    8) When the NEUTRAL line is present, connect it

    to terminal 4.

    9) To avoid shock and possible instrument

    damage, connect power last.

    Notes about limiter function

    The relay of the output 1 operates in fail-safe mode

    (relay de-energized during shutdown condition) and

    latching mode.

    The OUT 1 turns OFF when:

    - C1 = Hi and the measured value is greater than

    limiter threshold [“Su” parameter (see Operative

    parameters”)] or

    - C1 = LO and the measured value is less than

    limiter threshold [“Su” parameter (see Operative

    parameters”)] or

    - C1 = HiLO and the measured value is greater

    than “Su” parameter (see Operative parameters”)

    or less than “S1” parameter (see Operative

    parameters”).

    The Out 1 remains OFF until the condition which

    generated the shutdown, no longer exists and the

    acknowledge action has been performed.

    The upper display flashes during a shutdown and

    returns to a steady display when the shutdown

    condition no longer exists.

    When C2 = 0 and OUT 1 is OFF, the RESET LED is

    ON.

    When C2 = 1 one of the following condition may

    occur:

    - if no acknowledgement has been made, OUT 1 is

    OFF and the RESET LED is flashing;

    - if the acknowledgement has been made but the

    condition which generated the shutdown status

    still exists, OUT 1 is OFF and the RESET LED is

    steady ON.

    The shutdown condition can be stored in

    permanent memory (see C4).

    Acknowledgment can be performed by pressing

    the RESET key, by momentarily closing the

    external dry contact or by a command from the

    serial link.

    The length of the shutdown condition and max/min

    measured values are stored in memory and

    available for viewing until the next shutdown

    condition occurs.

    These informations are lost at power down.

    During a shutdown condition the max/min

    measured values are continuously updated and

    can be monitored.

    On powerup the device starts in the "Normal Display

    Mode."

    By pressing the or key, it is possible to change

    the displayed information; therefore, one of the following

    display modes can be selected:

    1) The upper display shows the measured value

    while the lower display shows the "Pu" (Process

    variable).

    If this display was active at power down, it will

    be active at powerup.

    2) The upper display shows the limiter threshold

    while the lower display shows "Su." If this

    display was active at power down, it will be

    active at powerup.

    3) The upper display shows the second limiter

    threshold while the lower display shows "S1."

    This information is available only if C1 = Hi.Lo.

    If this display was active at power down, it will

    be active at powerup.

    4) The upper display shows the total time (hh.mm)

    of the last shutdown condition while the lower

    displays shows “t.” If no shutdown condition

    was detected, the upper display will show “- - -

    -”. The information is lost at power down and

    at powerup the device will display the process

    variable.

    5) The upper display shows the maximum

    measured value detected during the last

    shutdown condition while the lower display

    shows "Ph.". If no shutdown condition was

    detected, the upper display will show “- - - -”.

    This information is not available if C1 = HI.Lo.

    The information is lost at power down and at

    powerup the device will display the process

    variable.

    NOTE: When the shutdown condition was

    generated by an input fault condition, the upper

    display will indicate “m.Err”

    6) The upper display shows the minimum mesured

    value detected during the last shutdown

    condition while the lower display shows "PL.” If

    no shutdown condition was detected, the upper

    display will show “- - - -”. This information is

    not available if C1 = Hi. The information is lost

    at power down and at powerup the device will

    display the process variable.

    NOTE: When the shutdown condition was

    generated by an input fault condition, the upper

    display will indicate “m.Err”

    If, at power off, the device was in shutdown

    condition and shutdown memoy function is

    selected (C4 = 0), and/or it was programmed for

    manual reset at startup (C3 = 1), then at the next

    power up the lower display will be flashing.

    Limiter functionLimiter function

    Limiter function

    The relay of the output 1 operates in fail-safe mode

    (relay de-energized during shutdown condition) and

    latching mode.

    The OUT 1 turns OFF when:

    - The instrument is configured as a high limiter

    (C1 = Hi) and the measured value is greater than

    limiter threshold [“Su” parameter (see Operative

    parameters”)] or

    - The instrument is configured as a low limiter (C1

    = LO) and the measured value is less than

    limiter threshold [“Su” parameter (see Operative

    parameters”)] or

    - The instrument is configured as a high/low

    limiter (C1 = HiLO) and the measured value is

    greater than “Su” parameter (see Operative

    parameters”) or less than “S1” parameter (see

    Operative parameters”).

    The Out 1 remains OFF until the condition which

    generated the shutdown, no longer exists and the

    acknowledge action has been performed.

    The upper display flashes during a shutdown and

    returns to a steady display when the shutdown

    condition no longer exists.

    When the OUT 1 is OFF the RESET LED is ON [if the

    selected rearming mode is equal to 0 (C2 = 0)] or flashes

    [if the selected rearming mode is equal to 1 (C2 = 1)].

    When the selected rearming mode is equal to 1

    (C2 = 1) the RESET LED is steady ON when OUT 1

    is OFF and acknowledged.

    The shutdown condition can be stored in permanent

    memory (see C4).

    Acknowledgment can be performed by pressing the

    RESET key, by momentarily closing the external dry

    contact or by a command from the serial link.

    The length of the shutdown condition and max/min

    measured values are stored in memory and available

    for viewing (see “Normal Display Mode”) until the next

    shutdown condition occurs.

    These informations are lost at power down.

    During a shutdown condition the max/min measured

    values are continuously updated and can be monitored.

    Example 1 - C1 = Hi and C2 = O

    Example 2 - C1 = Hi and C2 = 1

    Alarm functionsAlarm functions

    Alarm functions

    (Skipped if option is not available or P1 = none)

    The alarm can be programmed as:

    - process alarm

    - band alarm

    - deviation alarm.

    Band and deviation alarms are referred to the

    limiter threshold and are possible only if an high

    limiter or a low limiter function has been selected.

    For all the alarm types, it is possible to select

    automatic or manual reset or the “Silence”

    function.

    The "Silence" function is a typical function of the

    alarm annunciators (see ISA “Alarm annunciator

    operational sequence”) and it is usually applied to

    audible alarm indications (horn). This function

    allows the manual reset of the alarm even if the

    alarm condition is still in progress.

    It is also possible to assign to the alarm a stand by

    (mask) function.

    If the alarm is programmed as band or deviation

    alarm, this function masks the alarm condition after

    a safety threshold change or at the instrument

    start-up until process variable reaches the alarm

    threshold plus or minus hysteresis. If the alarm is

    programmed as a process alarm, this function

    masks the alarm condition at instrument start-up

    until process variable reaches the alarm threshold

    plus or minus hysteresis.

    Graphic example of the alarm behaviour are shown

    at pages 12 and 13.

    Serial LInk (optional)

    The device can be connected to a host computer via

    serial link.

    The host can put the device in LOCAL (parameters are

    controlled via keyboard) or in REMOTE (functions and

    parameters are controlled via serial link).

    REMOTE is shown by the decimal point to the left

    of "REM" which is on the right side of the numerical

    display.

    Via serial link it is possible to read and/or to modify all

    the operative and configuration parameters.

    The following conditions must apply to implement this

    function:

    1) Configure parameters L1 through L4 with the

    front keyboard.

    2) The device must be in the Operating mode.

    For other details require ENG 816-E document.
