option module. It must be af xed
to the indicating unit after the
option module is installed. A

2 Design and principle of oper-
ation
The option module with a 4to20mA
current loop can be added to the Media5
Differential Pressure and Flow Meter. It
allows the measured value to be
electronically processed for measuring and
control tasks. The loop current is proportional
to the pressure and is measured from the
pointer position of the Media5 device
without any contact or interference.
The option module is installed in the Media5
device. When ordered together with the
Media5 device, it is installed already in the
delivered state. In all other cases, it can be
retro tted by the customer.

Notes on explosion protection
The option module is available in two differ-
ent versions:
The following applies to the version with
explosion protection (100049064):
1. When working on explosion-protected
versions of the option module, personnel
must undergo special training or instruc-
tions or be authorized to work on explo-
sion-protected devices in hazardous ar-
eas.
2. The current loop must be supplied only
by a supply unit which has a equivalent
or higher explosion protection approval.
Its electrical connection data must be
lower or identical to those in the explo-
sion protection certi cate of the
Type5005-3 device.
3. Permission to operate the option module
in hazardous areas becomes void after
the following events:
–Oneofthepermissibleelectrical
values listed in the explosion-
protectioncerticateisexceeded,
evenwhenonlybriefly.To continue
operation of the option module in
hazardous areas in such cases,
SAMSON or a person with the
corresponding quali cations must
provide eviden that all safety/
protection features within the device
or module are fully effective.
–Thespecicationsdescribedin2.for
thesupplyunitarenotobserved.
Operation of the option module must
not be continued in such cases. The
option module must be replaced.

The option module consists of an actively
controlled current loop with a 4 to 20mA
loop current. This current depends on the
position of the pointer on the Media5
device:
−Pointer position 0 to 270° corresponds
with the 4to20mA loop current.
The measuring signal and supply voltage of
the option module are transmitted by the
same pair of wires. It is connected to the ter-
minal board over two spring-cage terminals.
Fig.10:Connecting the measuring signal lines
on the terminal board
The Media5 Differential Pressure and Flow
Meter supplies a 4 to 20mA current regard-
less of the supply voltage.
Risk of the supply voltage falling lower
than the required level due to the use of a
shunt.
ÎTo maintain the functioning of the option
module when a shunt is used, apply the
following formula to take the loop volt-
age into account: ULoop-min = 12V +
(Rshunt x 21mA)

issued at Δp=0bar corresponding to the
pointer's zero point.

between approx. –5° and 135° (see

The measuring span can be calibrated con-
tinuously without affecting zero or the mea-
suring accuracy (see Fig.12). The pointer
position corresponds to the end point with
20mA output signal.
As a result, the end points can easily be
adapted to the measured medium, especially
when attachable or multiple dial plates are
used.

4 Servicing explosion-protected
devices
ÎObserve the following for servicing
equipment in a section relevant for ex-
plosion protection:
– It must not be put back into operation
until a qualied inspector has
assessed the equipment according to
explosion protection requirements,
has issued an inspection certicate or
given the device a mark of
conformity. Inspection by a qualied
inspector is not required if the
manufacturer performed a routine
test on the device before putting it
back into operation. Document the
passing of the routine test by
attaching a mark of conformity to the
device.
– Replace explosion-protected
components only with original,
routine-tested components by the
manufacturer.
– Devices that have already been used
outside hazardous areas and are
intended for future use inside
hazardous areas must comply with
the safety requirements placed on
serviced devices. They must be
subjected to testing according to the
specications in EN60079-19.
– EN60079-19 applies to servicing
explosion-protected devices.
– Use the protective cable designed by
SAMSON when interconnecting non-
intrinsically safe set point calibrators
with intrinsically safe equipment for
repair, calibration etc. to ensure that
components relevant to explosion
protection are not damaged.
