About the blackbox range
The Pulsar blackbox is a non-contact Level Control System. It has been
designed to provide a new concept in low cost maintenance-free fit and forget
level measurement without any compromise on performance.
The blackbox is ideally suited to applications where level monitoring,
reporting, control or logging is required, with or without the need for a local
display.
The blackbox level system is available in a variety of different versions
offering a wide choice of output options.
The blackbox is very easy to use and may be calibrated quickly and simply
via a laptop, using the software supplied with the unit, or alternatively by
using the optional hand held calibrator, which connects to the unit via the
RS232 interface, and provides an on-board LCD display. Certain models are
also available with an optional LCD display and integral keypad fitted.
All models of the blackbox range can be used with any of the extensive range
of Pulsar dB transducers for distances up to 131ft (40m).
The blackbox range is designed to provide you with highly reliable
measurement in a robust and functional package that is easy to use and low in
cost.
Page 3
Functional Description
The blackbox ultrasonic Level System sends a transmit pulse to the
transducer, which emits an ultrasonic pulse perpendicular to the transducer
face, and the returned echo is sent back to the blackbox. The time taken to
receive the echo is measured and the distance from the transducer face to the
surface being monitored is calculated.
The blackbox utilises the unique DATEM software (Digital Adaptive
Tracking of Echo Movement). This is a unique digital mapping technique
developed especially for Pulsar’s range of ultrasonic level and control
systems. It gives the system edge when identifying the “true target level” in
the face of competing echoes from pipes, pumps or other obstructions.
The blackbox can measure from 0.41ft (0.125m) to 131 feet (40m) from the
transducer to the surface being monitored, dependent on the application and
transducer used.
The blackbox can measure level, space or distance and provide a
representative output. When fitted with the optional display and keyboard
it can also measure and provide an output representative of volume. There are
two user definable relays, with individual setpoints, which can be
programmed to activate alarms or control functions, a mA output that can be
used for remote indication purposes and a RS232 port, so that the blackbox
can be programmed or monitored remotely by a PC or other equipment.
The blackbox can be programmed either by PC, via the RS 232 Serial
Interface, using the supplied software (standard) or by hand held calibrator
(optional) which is connected to the blackbox via the RS 232 interface.
Those units fitted with the optional on board display can be programmed via
the integral keyboard.
All the parameters are stored in non-volatile memory, so are retained in the
event of power interruption.

Chapter 2 Installation
Power Supply Requirements
The blackbox can operate from AC supply or from a DC battery and is
designed for use in temperatures between -4oF to +140oF (-20oC to +50oC).
The AC is 115V +5%/-10%. The DC is 10-28V. In all cases the blackbox
will typically consume 5W of power, with a maximum of 10W. If the
blackbox has both an AC and DC supply available then the AC supply source
will be automatically sensed and used, should the AC supply be removed for
any reason then the DC supply will take over.
The AC and DC wiring should be completed using either 16 – 14AWG (1.5–
2.5mm2) stranded or 16 – 14AWG (1.5–4mm2) solid wire, with all terminals
being tightened to 4.5in. lbs. (0.5Nm).
An external supply isolator/circuit breaker (AC or DC) must be fitted and
labelled to identify the instrument to which it refers.

For EEx ia (Zone 0) a transducer certified to Sira 02ATEX2103X is used,
which must be connected to the blackbox via an external Zener barrier.
See transducer label for certification details.
Important Information
Please note that if the output of the ultrasonic transducers used with
blackbox are capable of emitting sound pressure levels in excess of
85dBA (above a reference sound pressure level of 20µPA), then the
blackbox must be located remote from the transducer such that a sound
pressure level of 85dBA is not exceeded when standing at the blackbox
in the operator’s position.
Page 17
Relay Outputs
The two relays can be programmed to a variety of alarm and control functions.
The relay contacts are all rated at 2A at 115V AC. Wiring should be
completed by using suitable cable, to meet the specified 115V AC 2A contact
rating, up to maximum size of 14AWG. All connections should be such that
the short circuit capacity of the circuit to which they are connected, is limited
by fuses rated so that they do not exceed the relay rating.
Current Output
This is an isolated mA output of 4 - 20mA or 0 - 20mA, and the load should
not exceed 1K.
RS232 Serial Interface
The serial interface is used to programme the blackbox either via a PC
(standard) using the software supplied or alternatively using the hand-held
calibrator (optional).
Fuse Location
The mains fuse is located, on the bottom board, to the left of the mains
terminals, as illustrated below.
Page 18
Important Information
Before applying AC power (mains), make sure the supply is 115 VAC
+5% / -10%
Never operate the blackbox with terminal access exposed.
An external switch or circuit breaker should be installed near to the
blackbox to allow the supply to be removed during installation and
maintenance. In addition, the relay contacts should also have a means
of isolating them from the blackbox.
Interconnecting cables must be adequately insulated in accordance
with local regulations. Strip back 30 mm of the outer insulation of the
cable. Strip 5 mm of insulation from the end of each conductor. Twist
all exposed strands of the conductor together. Insert the stripped
conductor into the terminal block as far as it will go and tighten the
terminal block screw. Ensure that all strands are firmly clamped in the
terminal block and that there is no excess bare conductor showing,
and no stray strands.
Important Information
If the equipment is installed or used in a manner not specified in this
manual, then the protection provided by the equipment may be
impaired.
Preparation for Operation
Before switching on, check the following:
✓ The blackbox is mounted correctly and is in a ‘safe’ area.
✓ The power supply is correctly installed.
✓ The relays are connected correctly.
Page 19
Maintenance
There are no user serviceable parts inside your blackbox, except the mains
power fuse. If you experience any problems with the equipment, then please
contact Pulsar Process Measurement for advice.
Important Information
Please note that the on-board Lithium battery, mounted to the
processor PCB, is not user serviceable.
To clean the equipment, wipe with a damp cloth. Do not use any solvents on
the enclosure or transducer.
Important Information
The unique DATEM software comes into operation as soon as
power is applied, and is designed to monitor a moving level or
target with the transducer in a fixed position.
If, after any period of use, it should become necessary to move the
transducer, for any reason, from its original operating position,
switch off the blackbox, before proceeding, to prevent any
undesirable updates to the DATEM trace. If after moving the
transducer the reading is not as expected, please refer to Chapter 6
Troubleshooting.

Chapter 3 How To Use Your blackbox Level System
In order to view or change parameter values one of the following methods
must be used:
PC Handheld Programmer (Standard)
Your blackbox 130 comes complete with the PC Handheld Programmer
software, contained on CD. Insert the CD into the CD drive of the PC intended
to be used to carry out the programming of the blackbox and install the
software, following the on-screen instructions. Once the software is installed
connect the computer via its serial port to the blackbox RS232 serial interface
RJ11 connector, located on the terminal connector strip, inside the blackbox
enclosure. Double click the ‘Handheld Programmer’ icon, installed on your
desktop and the PC will automatically connect to the blackbox. Once
connected you will briefly see the message illustrated on the display below
which, after connecting successfully, will then change to display the current
measurement, dependent on mode and measurement unit's chosen. When
using the PC Handheld Programmer software, keypad input can be achieved
by using a ‘mouse’ or similar device to place the cursor over the relevant key
followed by a ‘left’ click, alternatively numeric detail can be entered directly
from the PC keyboard as can ‘ENTER’ and ‘CANCEL’ (Esc. Key).
Page 21
Communication Port Configuration
If the PC Handheld Programmer fails to connect to the blackbox unit you
may need to change the communications port that is being used, to do this
‘right click’ on the PC Handheld Programmer keypad and a ‘pop up’ menu
will appear allowing you to select the appropriate communications port.
Handheld Communicator (Optional)
The optional Handheld communicator can be used to programme any number
of blackbox units and works in a similar way to the PC Software. Connect the
Handheld Communicator, with the cable supplied, to the RS232 interface via
the RJ11 connector located on the terminal connector, inside the blackbox
enclosure. Once connected you will briefly see a message, similar to that as
seen when using the PC Software which, after connecting successfully, will
then change to display the current measurement, dependent on mode and
measurement unit's chosen.
