Warnings and Cautions
Warning! Agency approval for hazardous location installations varies between flow meter models. Consult the flow meter
nameplate for specific flow meter approvals before any hazardous location installation.
Warning! Hot tapping must be performed by a trained professional. U.S. regulations often require a hot tap permit. The
manufacturer of the hot tap equipment and/or the contractor performing the hot tap is responsible for providing proof of such a
permit.
Warning! All wiring procedures must be performed with the power off.
Warning! To avoid potential electric shock, follow National Electric Code safety practices or your local code when wiring this unit
to a power source and to peripheral devices. Failure to do so could result in injury or death. All AC power connections must be in
accordance with published CE directives.
Warning! Do not power the flow meter with the sensor remote (if applicable) wires disconnected. This could cause over-heating of the
sensors and/or damage to the electronics.
Warning! Before attempting any flow meter repair, verify that the line is de-pressurized.
Warning! Always remove main power before disassembling any part of the mass flow meter.
Caution! Before making adjustments to the device, verify the flow meter is not actively monitoring or reporting to any master
control system. Adjustments to the electronics will cause direct changes to flow control settings.
Caution! All flow meter connections, isolation valves and fittings for hot tapping must have the same or higher pressure rating
as the main pipeline.
Caution! Changing the length of cables or interchanging sensors or sensor wiring will affect the accuracy of the flow meter.
You cannot add or subtract wire length without returning the meter to the factory for re-calibration.
Caution! When using toxic or corrosive gases, purge the line with inert gas for a minimum of four hours at full gas flow
before installing the meter.
Caution! The AC wire insulation temperature rating must meet or exceed 80°C (176°F).
Caution! Printed circuit boards are sensitive to electrostatic discharge. To avoid damaging the board, follow these
precautions to minimize the risk of damage:
before handling the assembly, discharge your body by touching a grounded, metal object
handle all cards by their edges unless otherwise required
when possible, use grounded electrostatic discharge wrist straps when handling sensitive components

Chapter 2: Field bus installation
All fieldbus connection for your Smart Meter is made on the right side:
Fieldbus Connector
The Profibus DP network is connected to the chassis female M12 connector (B-coded). The connector
has the following pin configuration:
(Front view)
The Profibus DP network can be connected with a special terminal block connection. This must be
requested at the time of ordering. The down side of this is the PB-5V and PB-GND will not be
available to power a terminator. You should also pull 2 Profibus cables to maintain the daisy chain
topography, to avoid spur lines.

Cable
Profibus cables are shielded twisted-pair copper cables which differ from each other in the type of
wire (fixed/flexible) and/or sheath. The two inner cores of a Profibus cable have green and red
insulation. The specifications in this chapter are primarily intended to provide a general introduction
and describe the cable properties to be considered (see also IEC 61784-5-3). A good cabling guide can
be found online at: http://verwertraining.com/wp-content/uploads/InstallationGuideV9_2.pdf .
The cable must conform to the following specifications:
Impedance: 150 Ohm (nominal) at frequencies from 3 to 20 MHz.
Cable capacitance: < 30 pF per meter.
Core diameter: > 0,34 mm², corresponds to AWG 22.
Cable type: twisted pair cable. 1x2 or 2x2 or 1x4 lines.
Resistance: < 110 Ohm per km.
Signal attenuation: max. 9 dB over total length of line section.
Shielding: CU shielding braid or shielding braid and shielding foil.
Max. Bus length: 200 m at 1500 Kbit/s, up to 1,2 km at 93,75 Kbit/s.

Termination
The Profibus physical layer is based on RS-485, and therefore termination resistors are needed at both
ends of the network. The image below shows how to connect the terminators:
Ready-made terminators are available for easy installation.
Status Leds
The interface has two multi-color LED’s mounted inside the enclosure to indicate the status. To access
the LED’s, remove the front cap.
The left LED shows the status of the interface, the right LED shows the network status.

Slave Address
Once the interface is installed, the slave address of the interface can be set. Default instruments will be
delivered with slave address 126. This address has been agreed by the Profibus organization to be free
for installing new devices to the bus. Changing the station address is done in two ways, either through
a dip switch or through the master.
Dip Switch
The dip switches are located inside the meter. Remove the display cover to expose the switches:
The dip switch is binary encoded with the LSB (lowest bit) on the left side. The switch is only read
during power-up.
The switch becomes active when the slider is moved upwards. Here some examples of some addresses
(1 = on/up, 0 = off/down):
LSB

125
1|0|1|1||1|1|1|0
Note: An address set with the dip switch has the highest priority and the slave address will use this
address when powering up!
Server Assigned Address
It is possible to change the address of the unit through the server. Perform the following steps to
change the address:
1. Assign a new address from the server
2. Set the dip switch to 128 (pin 8 on) or higher.
The assigned address will be used each time that the unit is powered.
Set Address (126)
It is possible to force the address of the unit to 126. Set the dip switch to zero and power cycle the unit.
The address is set to 126. The address can be changed by the server if needed. Do keep in mind that if
the dip switch remains set to zero, the address will be set to 126 at each power-up.

Syscon Software
Sycon is a tool for the configuration of a Fieldbus network using a Hilscher CIF50-PB master. You
may be using different configuration software and hardware Master. However you will need to
accomplish the same functions. No specific slave DTMs of the equipment are available, which are
generated from the device description files, called generic slave DTMs.
Online diagnostic indicators and auto-scan function for the reading of network participants assist in the
commissioning of the network.
This guide will explain step by step how to configure the system to support various fieldbus slaves on
a Hilscher CIF50-PB master.
Before starting make sure that the necessary device description files (GSD & bit maps) are available in
your device catalog. These are available on our web site.
Import Device Description Files
In order to use a fieldbus device its properties need to be added to the server. This is done by
importing the device description files into Sycon.
Start Sycon and create a new document (File -> New)
A dialog window appears asking to select a fieldbus. For this example select Profibus:
The main window is loaded. Go to the file menu and select “Copy GSD”:

15
Locate the desired GSD file and load it. The GSD data is added to the Sycon library but it isn’t
available yet. Quit the program and restart it to make it available.
Configure A Slave
Create A New Document And Insert A Master:
Place the master at the top of the line. A dialog window appears where a master needs to be selected
from a list. The list shows every type of master supported by Sycon. Select the Profibus master which
has been installed on the PC:
