GENERAL INFORMATION
IMPORTANT
First and foremost it is essential that this manual be read and understood before
installation and start up of the MultiRanger Plus.
"Applications" provides a general description of the common applications found in
industry and illustrates them with examples. It is suggested that you refer to the
sub-section which most suits your application. The programming of the MultiRanger
Plus can be optimized by referring to Parameter Description or Appendices \
Alphabetical Parameter Listing.
THE MULTIRANGER PLUS
The MultiRanger Plus is a multi-purpose level monitoring system consisting
of a MultiRanger Plus in a CSA type 4 enclosure, a programmer and an
ultrasonic transducer.
The MultiRanger Plus emits an ultrasonic pulse via the transducer. The echo is
reflected from the material and received by the transducer. The echo is processed by
the MultiRanger Plus and the time at which the ultrasonic pulse hits the level or target
is extracted and compared to the time at which it was sent. The time differential is
then converted into distance, material level, volume, flow or differential level as a
basis for display, relay control, analog output and totalling.
As well as simple level measurement, the MultiRanger Plus was designed to handle
specific applications such as: pumped volume totalling, differential level and open
channel flow measurement.

INSTALLATION
MULTIRANGER PLUS
The MultiRanger Plus should be mounted in an area that is within the unit’s ambient
temperature range, and is suitable for CSA type 4 enclosures and polycarbonate
material. The front cover should be accessible for programming and viewing.
It is advisable to keep the MultiRanger Plus away from high voltage or current runs,
contactors and SCR control drives.
Do not mount the multiranger plus in direct sunlight
without the use of a sun shield.

CURRENT OUTPUT ISOLATOR
If the isolator has not been factory installed, mount it on the upper left hand corner of
the motherboard using the two long machine screws provided. The input terminals of
the isolator are then connected to the motherboard output terminals,TB-1, using
twisted pair maximum 16 gauge wire.
Proper shielding and grounding are required in order to minimize noise levels that
could otherwise affect weak receiver signals by introducing false echoes.
The isolator enclosure is grounded by the mounting bolts to the motherboard. This
can be checked with an ohmmeter if a poor connection is suspected.
The isolator output wiring must be a shielded twisted pair. The shield must be
intact up to the isolator and the shield grounded at the isolator mounting screw
only. Do not ground shield at any other point as this will void isolation.

SYNCHRONIZATION
In applications where more than one MultiRanger Plus, up to a maximum of 8, are
going to be used or where their transducers will be sharing a common conduit,
synchronization is required. When synchronized, no MultiRanger Plus(s) will transmit
within 180 msec of the prior one(s).
To synchronize MultiRanger Plus’s, interconnect the SYNC terminals TB1-4 of all
motherboards and ensure that there is a common hydro ground interconnecting
all units.
To synchronize MultiRanger Plus’s and MultiRangers, interconnect the SYNC terminal
TB1-4 of the MultiRanger Plus to the SYNC terminal TB1-9 of the MultiRanger.
To synchronize more than 8 MultiRangers or MultiRangers with other Milltronics
ultrasonic level detection models (e.g. MicroRanger, AirRanger, etc...) consult
Milltronics or your distributor.
All units to be synchronized must be
interconnected by a common hydro ground.

PROGRAMMER
In order to program the MultiRanger Plus, a programmer ( which has a magnetic back
plate ) must be placed into the front cover recess on the MultiRanger Plus. Be sure to
keep it away from objects such as floppy disks that are susceptible to damage from
magnetic fields.
A programmer need not be ordered with each unit.
Check your order if you think that the programmer is missing.

START UP
GENERAL
The MultiRanger Plus has two modes of operation: Run and Program (Cal). When
the unit is powered up, after installation procedures have been completed, it is factory
set to start up in the run mode, to detect the distance from the transducer face to the
target in meters. This is the normal mode of operation, which can be programmed to
display level, volume, totals or flow readings and yield corresponding mA output and
relay closures for alarms, pump controls, etc.
The program mode is selected by pressing the
Run/Cal key. This mode will enable
the user to program the MultiRanger Plus to suit his preference and to the particular
application to which the MultiRanger Plus is being applied.
The first step when programming is to reset all parameters to their
factory setting by using the master reset P-99
After having entered all required parameters, the MultiRanger Plus can be made to
simulate its operation within the particular application giving display, relay operation
and analog output. Refer to parameters P-76 through P-78.
When programming has been completed, the MultiRanger Plus can be put into normal
operation by pressing the
Run/Cal key.
