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,
especially during servicing. Once the unit is installed, grounded and interconnected, the chances
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 BC01 application is a dual stage batch controller for reliable
measurement of preset quantities using a volumetric frequency or analog
input. Used as a single or dual stage controller it is suitable for fast batch
applications.
It provides the operator with clear local readout 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. Overrun compensation caters for system delays such as
valve closure for precise quantities.

Introduction
2 515 BC01 - 23 August 2019
The instrument is compatible with a wide range of flowmeter outputs,
including millivolt signals, reed switches, pulse, Namur proximity switches
and analog signals. Inputs can be scaled, filtered and have non-linear
correction applied. Square law and cutoff points can also be applied to the
analog input.
Calculations
If using the frequency input, the total and flowrate are derived from
accurately measured frequency and the number of received pulses.
volume = pulses / k-factor
volume flow = frequency / k-factor
If using the analog input, to derive the flow rate the input is normalised to a
value (A) between 0 and 1.
volumeflow = (Vf max-Vf min)A+Vfmin
Automatic overrun compensation calculates the new valve closure point to
ensure correct delivery by averaging the overrun amount from the last three
complete batches.
The overrun compensation value is valid for a new preset value provided the
stored overrun is less than 20% of the new preset.
Analog Input Scaling
The analog inputs in this instrument are scaled by the following general
formula:
where:
Correction Type
•LINEAR: when the instrument is not required to apply
correction
•NON-LINEAR: when the instrument applies correction from
the points in the correction table
•SQUARE when the transmitter does not have square
root extraction and it must be applied by the instrument.

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 84 for the list of
available units.
Communications
There are two communication ports available as follows:
•COM-1 RS-232 port
•COM-2 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 4-20 mA 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 programmed to suit the particular application needs
and the flexible I/O can be assigned as required. Program settings can be
changed either via the front panel (depending on assigned access levels) or
via the 500 Series Program Manager (500-PM software).
The 500-PM software is a free comprehensive configuration tool and
resource centre that can be used to further tailored an instrument to suit
specific application needs including units of measurement, custom tags and
text, access levels and more.
The software is a Windows based program that is freely available from the
download section of the Contrec website. The program can be used to create
a custom version of an existing application to be saved for backup purposes
and/or to generate a PDF of configuration report for record keeping.
The instrument stores all set-up parameters, totals and logged data in non-
volatile memory with at least 30 years retention.

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
139 mm wide by 67 mm high. Two side clips secure the unit into the panel.
shows the panel mounting requirements for the 500 Series Instrument.
