GENERAL INFORMATION

ABOUT THIS MANUAL

It is essential that this manual be referred to for proper installation and operation
of your MiniRanger Plus. As MiniRanger Plus requires an STH or Echomax ultrasonic
transducer to make a working system, refer to the associated transducer manual
as well.

ABOUT MINIRANGER PLUS

GENERAL INFO.

MiniRanger Plus is a versatile material level monitoring instrument. Material level
measurement is achieved using advanced sonic echo ranging techniques. The unit is
complete with an integral multifunction liquid crystal display, a four button keypad and
an integral junction box.

Remotely coupled to an appropriate transducer, MiniRanger Plus is well suited for
short to medium range measurements of liquids or solids, in open or closed vessels.
MiniRanger Plus is at home in a wide variety of industries: food, pharmaceutical,
chemical, water, waste water - to name a few.

The MiniRanger Plus emits a series of ultrasonic pulses from the associated
transducer. Each pulse is reflected as an echo from the material and sensed by the
transducer. The echo is processed by the MiniRanger using Milltronics’ proven ‘Sonic
Intelligence’ techniques. Filtering is applied to help discriminate between the true echo
from the material, and false echoes from acoustical and electrical noise and agitator
blades in motion. The time for the pulse to travel to the material and back is
temperature compensated and then converted into distance for display, mA output
and relay actuation.

MiniRanger Plus is equipped with a two-way infrared link for compatibility with
Milltronics Dolphin communication system.

MiniRanger Plus features:

✓ multi-field LCD for: parameter, reading and bar graph display, and relay

and fail-safe status.

✓ two alarm / pump control relays
✓ quick connect wiring terminals
✓ high level switch operation
✓ lead / lag pump operation
✓ Dolphin compatibility
✓ isolated mA output
✓ sonic intelligence
✓ integral keypad

INSTALLATION

SYNCHRONIZATION

In applications where more than one MiniRanger Plus, to a maximum of 8, are going
to be used or where their transducers are sharing a common conduit, synchronization
is required. When synchronized, no device transmits within 180 ms of the prior one(s).

To synchronize, interconnect the SYNC terminals of all devices and ensure that there
is a common electrical ground interconnecting all units.

To synchronize MiniRanger Plus with other Milltronics products, consult Milltronics or
your distributor.

START UP

GENERAL

The MiniRanger Plus has two modes of operation:
is powered, after installation procedures have been completed, it is programmed to
start up in the run mode, to detect the distance from the transducer face to the target
in meters.

The unit can be placed into the program mode at any time; to alter a number of
program parameters in order to better suit the application or user’s preferences.
Programming can be carried out via the local keypad or the optional Dolphin
infrared interface.

The first step when programming is to reset all parameters to their factory setting by
using the master reset P-999. This must be done via the local keypad.

For a Quick Start, P001 to P007 are the key parameters requiring entry.
They set: - mode of measurement

- process material

- transducer type

- measurement response

- units

- empty distance

There are a number of other program parameters, especially relay and mA output,
that can be changed subsequently or during another programming session. Refer to
Parameter List for a description of the parameters available.

When programming has been completed, the MiniRanger Plus can be put into normal
operation by pressing .
