SAFETY INSTRUCTIONS 1
MFC 300
1.1 Scope of the document
These instructions are supplementary to the standard product documentation of the signal
converter. The details depicted therein, in particular the safety information are valid and should
be adhered to. The present supplementary instructions provide additional information for the
devices when being operated and connected to a Foundation Fieldbus.
INFORMATION!
The present supplementary instruction for the signal converter with Foundation Fieldbus
interface, plus the software with the DD and CCF files are included in our scope of supply, in
addition to those items delivered for the standard device.
1.2 Device description
The mass flowmeters are designed exclusively to directly measure mass flow rates, product
density and temperature as well to indirectly measure parameters such as the total volume and
concentration of dissolved substances as well as the volume flow rate.
Your measuring device is supplied ready for operation. The factory settings for the operating
data have been made in accordance with your order specifications.
The following versions are available:
• Compact version (the signal converter is mounted directly on the measuring sensor)
• Remote version (electrical connection to the measuring sensor via field current and signal
cable)

ELECTRICAL CONNECTIONS 3
MFC 300
3.1 Installation in hazardous area and bus cable
We recommend that a Foundation Fieldbus network in the hazardous area should be projected in
accordance with PTB's FISCO model. The FISCO model is based on the following conditions:
• All electrical components which should be connected to the bus must be approved according
to the FISCO model (even the termination).
• The maximum cable length should not exceed 1000 m / 3280.8 ft.
• The approved input values of the field devices (U0, I0, P0) comply to the output values of the
power supply (e.g. segment coupler) according to: U0 ≤ Ui; I0 ≤ Ii; P0 ≤ Pi.
• The values of the cable must be within the following ranges:
R' = 15…150 Ω/km; L' = 0.4…1 mH/km; C' = 45…200 nF/km
equivalent to
R' = 24…240 Ω/mile; L' = 0.65…1.6 mH/mile; C' = 72…320 nF/mile
Other limitations for the cable than the FISCO limitations are not existent. Nevertheless, a
twisted pair and shielded cable is strongly recommended.
Example: a good quality cable could have the following data: 44 Ω/km = 70.4 Ω/mile; <90 nF/km
= <144 nF/mile; attenuation at 39 kHz: <3 dB/km = <4.9 dB/mile; impedance 100 Ω at 31.25 kHz.
3.2 Foundation Fieldbus electrical connection
The output and input groups are electrically isolated from each other and from all other input
and output circuits.
DANGER!
The signal converter must be properly grounded to avoid personnel shock hazard. All directions,
operating data and connection diagrams do not apply to devices used in hazardous areas; in such
cases, read the special Ex instructions without fail!
3.3 Cable types
The cable types are specified according to IEC 61158-2. Shielded cables offer the advantage of
malfunction-free operation with adequate protection against electromagnetic influences, and
make it possible to employ the full performance of the Foundation Fieldbus system.

All bus segments must be fitted with a terminator at both ends.
3.4 Shielding and grounding
• For optimum electromagnetic compatibility of systems it is extremely important that the
system components, and particularly the bus cables connecting the components, are
shielded and that such shields - if possible - form an unbroken cover.
• Hence, it follows that, for use in non-hazardous duty systems, the cable shield should be
grounded as often as possible.
• In Ex systems an adequate equipotential bonding in the hazardous and non-hazardous
location along the entire Fieldbus installation is strongly recommended. Multiple grounding
of the shield is of advantage.
• In explosion-proof systems the shielding must at least be connected at one end of the cable.
• NAMUR NE 21 compliance is given, provided the above recommended cable types are used.
INFORMATION!
The use of twisted and shielded cables is strongly recommended, otherwise EMC protection of
the signal converter cannot be assured.

4.2 Description of the FF block system
The Foundation Fieldbus is a Local Area Network (LAN) for connecting field devices like sensors
and actuators. One of the main benefits of Foundation Fieldbus is line saving in comparison to
the traditional 4...20 mA technology.
The different device functions are implemented in a block-based scheme within a user
application. In this block scheme, a distinction is made between the Resource Block, Transducer
Block and Function Block.

INTEG_OPTS
R/W
Integration Options
Description and settings
Initial Value
INTEG_OPTS is to be used to specify several integration
options as type of input used in each input, flow direction to be
considered in the totalization, status to be considered in the
totalization and if the totalization residue shall be used in the
next batch after a reset.
Uninitialized
The following INTEG_OPTS are possible (see also
INTEG_TYPE):
• Input 1 accumulate: IN_1 is used as pulse (otherwise as rate)
• Input 2 accumulate: IN_2 is used as pulse (otherwise as rate)
• Flow forward: only positive net flow will be taken into
account for totalization
• Flow reverse: only negative net flow will be taken into
account for totalization
• Use Uncertain: IN_1 and IN_2 input will be taken into
account even if their states are "Uncertain" (otherwise the
value with the last "Good" status will be taken)
• Use BAD Input: IN_1 or IN_2 with "Bad" status will be
interpreted as "Good" (Note: only the status is interpreted as
"Good", the value isn't used for totalization, but the good one,
i.e. RTOTAL isn't affected with this setting.
• Carry: integration after a reset starts with the init value, but
with the residual after the trip value.
• Add zero if Bad: if one of the input (IN_1 or IN_2) statuses are
"Bad", not the last "Good" value is used for totalization, but
zero (0).
• Confirm reset: after a manual reset of totalization, the next
manual reset must be preceded by a reset confirmation by
the control system.
• Generate reset event: in case of reset (automatic or manual),
an event notification will be sent to the control system.
(This function is an option and not supported.)
