About the
Ultra 5
Ultra 5 is a brand-new concept in ultrasonic level measurement. Within its
memory are all the functions and settings of three different and completely
separate ultrasonic devices.
The Ultra 5 does not offer a multiple range of functions blended together
which lead to complicated calibration and a compromise to the specification,
Ultra 5 is the first ever system to offer the ability to dedicate the
functionality of the unit to any of four specific duties i.e. level or volume
measurement, pump control, differential level or flow measurement.
The benefits are many but most importantly the unit provides:
1. A most versatile system which is quickly configurable to offer anyone
four separate functions within seconds. Ideal for simplicity of purchase
and off the shelf spares.
2. A totally dedicated device with the ability to perform all aspects of the
task required i.e. no compromise in specification.
3. Easy to set up using the unique “Quick Set Up” Menu. To calibrate, first
set the Ultra Wizard for the desired task, and then refer to the relevant
chapter in this manual that relates to your application:
Chapter 5 for Level or Volume,
Chapter 6 for Pump Control or Differential Level
Chapter 7 for Flow
Page 3
Functional Description
Ultra 5 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 Ultra 5. The time taken to receive the echo is measured and the
distance from the transducer face to the surface being monitored is
calculated.
Ultra 5 can measure from zero to 40m from the face of the transducer to the
surface being monitored, dependent on the application chosen and
transducer used.
The relays can be programmed to activate alarms, pump starters, or other
control equipment. There is an isolated 4-20 mA output that can be
connected to a recorder or PLC, to monitor, depending on application
chosen, level space or distance, OCM head, OCM flow or volume,
independently from that shown on the display. There is an RS232 port, so
that the Ultra 5 can be operated remotely by a PC or other equipment.
Ultra 5 can be programmed either by the built-in keypad (standard on all
wall and fascia units), or by PC via the RS 232 Serial Interface (optional).
The optional rack and panel mounted units are programmed with the
“Remote Communicator”, and one Communicator can program many Pulsar
Ultra 5 units. All parameters are stored in non-volatile memory, so are
retained in the event of power interruption. A second backup copy of all
parameters can also be retained in the Ultra 5 memory, in case an alternative
set of parameters needs to be stored.
Five user definable control relays with individual setpoints and intelligent
performance logging software features ensure maximum control versatility.
The system utilises the unique DATEM software (Digital Adaptive
Tracking of Echo Movement). This is a proven digital mapping technique
developed especially for the Pulsar Ultra range, which gives the system
unequalled ability when identifying the “true target level” in the face of
competing echoes from pipes, pumps or other obstructions. Coupled with
the powerful, long-range abilities of the ‘all new’ dB transducer range, the
Ultra 5 lives up to its reputation as the most reliable ultrasonic level
measurement system available.
The Pulsar Ultra 5 ultrasonic level controller has been designed to provide
maintenance-free fit and forget performance.

Chapter 2 Installation
Power Supply Requirements
Ultra 5 can operate from AC supply or from a DC battery. The AC is either
105-120V 50/60Hz or 170-240V 50/60Hz, depending on the position of the
selector switch. The DC is 18-36V. In all cases the Ultra 5 will typically
consume 6W of power, with a maximum of 10W.
Location
All electronic products are susceptible to electrostatic
shock, so follow proper grounding procedures during
installation.
Ultra 5 must be mounted in a non-hazardous (safe) area, and the transducer
fitted in the hazardous area.
Page 12
When choosing a location to mount the enclosure, bear in mind the
following:
• Ensure that the Ultra 5 is installed in a “Safe”, non-hazardous, area.
• For a clear view of the LCD display it is recommended that it is
mounted at eye level.
• The mounting surface is vibration-free.
• The ambient temperature is between -20ºC and 50ºC.
• There should be no high voltage cables or inverters close by.
Dimensions
Wall mount
The dimensions of the wall fixing holes are as shown below.
Ultra 5 should be mounted by drilling three holes suitable for size 8 screws
(length to suit your application), and fixing the top screw in place. Hang the
unit on this and fix the two remaining screws by removing the terminals
access cover to access the pre-drilled holes.
Page 13
The full dimensions of the enclosure are as shown below.
Page 14
Cable Entry
There are 6 cable gland knockouts on the base of the Ultra 5 (5 x M20,
1 x M16) and 4 on the rear (4 x 18mm dia (PG11)). Select which ones you
wish to take out, and remove them by using a circular cutter, such as a tank
cutter. Take care not to damage the circuit board inside whilst undertaking
this. Do not use a hammer, as this may cause damage to the enclosure.
It is recommended that you use suitable cable glands to ensure that the
ingress rating is maintained.
Fascia Mount
The Fascia mount Ultra 5 should be installed by cutting a hole in the panel
as detailed below.
Page 15
The full dimensions of the Fascia mount enclosure are as shown below.
Page 16
Rack ad Panel
The Ultra 5 rack mount unit is a standard 10HP plug in unit, for a standard
84HP (19”), 160 mm sub rack unit.
The backplane that is supplied with the rack unit should first be fitted to the
back of the sub rack, so that when the rack unit is inserted into the rack it
connects correctly.
To install the unit into the sub rack, slide the Ultra 5 into the rack and secure
by tightening the four captivated screws that are in the faceplate.
The panel mount unit should be installed by cutting a hole of size DIN 68
+0.7
x 138
+1.0
mm in the panel, then insert the Ultra 5 enclosure through the hole,
and tighten the fixing screws from the rear. Make sure you leave sufficient
room for the cables behind the enclosure (a depth of at least 225 mm behind
the panel should suffice).
All electronic products are susceptible to electrostatic
shock, so follow proper grounding procedures during
installation.

For Zone 1 applications a transducer certified to Sira 02ATEX5104X is
used, and must be supplied via a 4000A breaking fuse, which is fitted as
standard to the Ultra 5.
For Zone 0 a transducer certified to Sira 02ATEX2103X is used, which
must be connected to the Ultra 5 controller via an external Zener barrier.
See transducer label for certification details.
Single Transducer mode is used to measure space, level, distance, volume
or flow and the transducer should be connected to Transducer 1 input
terminals.
Dual Transducer mode is used to measure Differential and Average. For
Differential, the upstream transducer should be connected to Transducer
1 input terminal and the downstream transducer to Transducer 2 input
terminal. In cases where the Ultra 5 is required to measure Average, then
transducers can be connected to either one.
Relay Outputs
The five relays can be programmed for a variety of alarms, pump control, or
other process functions. The relay contacts are all rated at 5A at 240V AC.
All connections should be such that the short circuit capacity of the circuits
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 (floating) mA output (to 150 V), of 4 - 20mA or 0 20mA, and the load should not exceed 500 .
Current Input (Optional)
This feature is available as an option only. Please consult Pulsar for further
details. The current input is an isolated (floating) mA input (to 150 V), 4 20mA or 0 -20mA.
Temperature Input (Optional)
The external temperature sensor allows more localised compensation of the
measured distance due to changes in temperature.
There are two models, Type A and Type B as follows:
Type A
-25ºC to 50ºC
Type B
-25ºC to 125ºC
