Safety Notice
The information in this safety notice is for the prevention of injury to personnel and
damage to the instrument.
The manufacturer assumes no liability for injury or damage caused by misuse of the
instrument or for modifications made to the instrument.
Qualified Personnel
The instrument must be installed, operated and serviced by persons who have been properly
trained and authorised. Personnel must read and understand this manual prior to installation and
operation of the instrument.
Static Hazard
The 500 series flow computer uses high speed CMOS circuitry which is sensitive to static
damage. The user should observe accepted safety practices for handling electronic devices,
especiallyduringservicing.Oncetheunitisinstalled,groundedandinterconnected,thechances
of static damage are greatly reduced.
Voltage Hazard
Before connecting power to the instrument, ensure that the supply voltage for the AC or DC
input is suitable. The AC voltage rating is as stated on the instrument rating plate. Personnel
should take all due care to avoid electric shock. For safe operation it is essential to connect a
mains safety earth to the A.C. power inlet. Do not operate at altitudes above 2000m.
Welding Hazard
Do not perform electric welding in close proximity to the instrument or its interconnecting
cables. If welding in these areas must be performed, disconnect all cables from the instrument.
Failure to do so may result in damage to the unit.
Moisture Hazard
To avoid electrical faults and corrosion of the instrument, do not allow moisture to remain in
contact with the instrument.
Disconnection Device
When powered from a mains supply this unit requires the provision of a suitable mains isolation
device to be accessible near to the installed instrument.

Overview
The 515 BR02 application is a batching flow controller for delivery of
preset quantities at preset flowrates using a volumetric analog input. Batch
control can operate in preset or on-off modes, while flow control can be set
to local (manual) or PI loop mode.
515 BR02 - 17 June 2017

Introduction
2 515 BR02 - 17 June 2017
This application provides the operator with clear local readout including
flowrate deviation and can be controlled via communications in more
automated systems. There is quick access to commonly used preset values
directly from the front panel if access has been authorized.
The PI control of the process flow is via a 4-20mA proportional valve or
pump controller. It has integral wind-up protection, a deadband, output hold
and ramp time that can be programmed to reduce wear on valves and
actuators and provide for bumpless operation.
Calculations
There are three types of control modes in which the process flow is
dependent on the main flow. These are RATIO, BLEND-1 and BLEND-2
modes where the relationship between the flows are as follows:
Ratio Control Mode.
The process flow is a ratio of the main flow (0 to 400% range).
Blend Control Modes.
These modes cater for blending points before and after the main flowmeter.
The process flow is a ratio of the net (combined) flow (0 to 80% range).
Displayed Information
The front panel display shows the current values of the input variables and
the results of the calculations.
The instrument can be supplied with a real-time clock for storage of up to
1000 transactions with time and date stamps.

Main Menu Variables
Refer to Available Units of Measurement on page 86 for the list of
available units.
Communications
There are two communication ports available as follows:
•RS-232 port
•RS-485 port (optional)
The ports are available for remote data reading, printouts and for initial
application loading of the instrument.
Isolated Outputs
The opto-isolated outputs can retransmit any main menu variable. The type
of output is determined by the nature of the assigned variable. Totals are
output as pulses and rates are output as 4-20mA signals. One output is
standard, a second output is available as an option.
Relay Outputs
The relay outputs 1 and 2 are used to control the flow of product for each
delivery. These contacts are normally open and can be used to drive external
relays, valves, pump circuits etc. The advanced option provides another two
relays that can be used as fully programmable alarms for any rate type
variable.

Software Configuration
The instrument can be further tailored to suit specific application needs
including units of measurement, custom tags, second language or access
levels. A distributor can configure these requirements before delivery.
Instrument parameters including units of measurement can be programmed
in the field, according to the user access levels assigned to parameters by the
distributor.
All set-up parameters, totals and logged data are stored in non-volatile
memory with at least 30 years retention.

FCC Declaration
This equipment has been tested and found to comply with the limits for a
Class A digital device, pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interference
when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy and, if
not installed and used in accordance with the instruction manual, might
cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference, in
which case the user will be required to correct the interference at his own
expense.
Properlyshieldedandgroundedcablesandconnectorsmust be used in order
to meet FCC emission limits. Contrec Ltd is not responsible for any radio or
television interference caused by using other than recommended cables and
connectors or by unauthorized changes or modifications to this equipment.
Unauthorized changes or modifications could void the user's authority to
operate the equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to
the following two conditions: (1) this device might not cause harmful
interference, and (2) this device must accept any interference received,
including interference that might cause undesired operation.

Installation
Panel Mounting
The instrument should be located in an area with a clean, dry atmosphere
that is also relatively free of shock and vibration.
The standard mounting procedure is panel mounting in a cutout that is
139mm wide by 67mm high. Two side clips secure the unit into the panel.
Figure 2 shows the panel mounting requirements for the 500 Series
Instrument.
