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 communica­tion cables.

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

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

(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.
