USER MANUAL
INTRODUCTION
Miniflex LR is a programmable multi-purpose level measurement and flow control
instrument. It consists of two elements, a wall mounted transceiver, which has a display and
an integral keypad for programming, and a transducer, which must be mounted directly above
the surface to be monitored.
Ultrasonic pulses are transmitted by the transducer to the surface of the material to be
monitored and are reflected back to the transducer. The time period between transmission and
reception of the sound pulses is directly proportional to the distance between the transducer
and the material.
Since speed of sound through air is affected by changes in temperature, a separate or
integrated temperature sensor may be fitted to improve accuracy.
Miniflex LR is capable of the following functions:-
a) Distance Measurement (distance from a datum)
b) Level Measurement (height above datum)
c) Volume Measurement
d) Pump Control
e) Open Channel Flow Measurement (O.C.M.)
f) Differential Level Measurement

INSTALLATION
Transceiver For ATEX hazardous areas refer to Appendix 3.
Enclosure mounting
Secure one of the three fixing screws provided with the instrument 30mm below the centre of
where the top of the instrument is to be located. This fixing screw will need to be left 4mm
proud of the surface allowing the instrument to be hung from this point. The instrument is
then secured in place by 2 more screws using the two mounting slots exposed when the
terminal cover is removed. DO NOT use excessive force when tightening the fixings and
avoid any distortion of the enclosure.
Ensure that the mounting surface is not subject to vibration and is not in close proximity to
high voltage cables, contactors or drive controls. The unit should not be mounted in a
confined space where temperatures may exceed the normal working temperature. If the unit
is mounted outside, it must be protected from direct sunlight or severe weather conditions.
Select appropriate knockouts in the base of the enclosure and fit appropriate cable glands to
maintain the IP65 rating.

Figure 4: Transducer mounting diagram
An isolation kit is provided with each transducer to minimise any ringing transmitted through
the mounting structure.
The transducer must be mounted perpendicular to the monitored surface and, ideally, at least
0.5 metres above it.
The transducer has a 12° inclusive conical beam angle at -3dB and must be mounted with a
clear unobstructed sight of the liquid to be measured over the complete measurement range.
The transducer is provided with integral cable which can be extended up to 300 metres using
a suitable junction box and RG62AU cable. The temperature compensated transducer
requires an additional single core screen extension, or twin-ax cable.
Refer to Page 8 for full details.
Transducer cables and temperature compensation cables can be run together but
should be separated from power cables by at least 150mm and preferably installed in
their own earthed steel conduit.

Standpipe Installations
In many applications access to a vessel must be made via a standpipe. However, it is
necessary to observe some basic rules when fitting transducers into standpipes.
BLANKING: Parameter 4.0 should always be set at least 150mm longer than the
length of the standpipe.
STANDPIPE should be in accordance with the following table
DIMENSIONS:
Flange size and minimum
bore of Standpipe
of Standpipe
Maximum length
3" ( 80mm) 300mm
4" (100mm) 300mm
e.g. Using a 4" flanged transducer would require the standpipe length to be no more than
300mm and Pr.4.0 set at 450mm minimum.
The inside of the pipe and joint with vessel top must be clean and free of any
obstructions, seams or welds.

EASY START FOR MINIFLEX LR
The Miniflex LR system requires programming by the operator to obtain the required
measurements and control. To create a basic working system, only the application type and
parameters 2.0 to 5.0 need be programmed. To become familiar with the use of the system, it
is suggested that the following QUICK START guide is used before the instrument is
installed.
Quick Start Guide
1. Connect power and transducer cables as defined on the instrument.

Transducer ac Power Supply
Terminal Nos: [1 ] [2] [ 6 ] [ 7 ] [8 ] [ 23 ] [ 24 ] [ 25]
+ve -ve Shield Blue Black E N L
2. Close the front cover and secure in position before switching on the power.
The instrument is supplied factory set to work in distance measurement
up to 10 metres from the transducer.
3. Hold the transducer approximately 1.5 metres from a flat surface and switch on.
After a short period, the display will show the distance (e.g. 1.50) between the
transducer and the surface.
If the transducer is now moved slowly towards the surface, the reading should
decrease. This shows that the unit is correctly wired and is operating as expected in
response to the reduction in distance.
If the reading increases as the transducer is moved towards the surface, it indicates
that the unit has been previously programmed to read level not distance.
Principle of Programming
The Miniflex LR has two modes:-
a) RUN (Normal operating)
In the 'RUN' mode, the instrument is monitoring the target, displaying values, and setting
outputs as programmed by the operator.
b) Program Mode (Programming)
In the 'Program Mode' the operator uses the keypad in conjunction with the display to adjust
the settings and to test that the unit is programmed correctly.
Keypad Definitions
The keypad consists of 5 keys, which are used to programme the operation of the transceiver. These
keys also have secondary functions enabling the operator to view the results being obtained by the
instrument during its normal 'RUN' cycle.
Ref: MINIFLEX LR MANUAL Rev. 0 10
SECTION 2
Primary Key Functions
M = Mode Key - to go from "RUN" to "Program Mode”

Alternative Key Functions
The 4 peripheral keys have secondary functions which can be viewed without interrupting the
instrument's operation. In the normal "RUN" mode:-
Press = Display will show head and flow values when in OCM mode.
Press = Display will show the echo distance in metres and "GAIN" with a value
from 0.2 to 100, which represents strength of echo. Low numbers mean
strong echo.

Relays
The 3 relays can be assigned to various functions depending on the application, as shown
below:
Hysteresis is fully adjustable, so for most functions it is necessary to enter both "set" and
"reset" values.
The relay state under normal operating conditions is defined as:-
Normally energised. De-energise when "set" value is reached.
Normally de-energised. Energise when "set" value is reached.
"Failsafe" functions are detailed in Pr.10.1 – 10.5.
The relays can be programmed to give both high and low alarm or control levels.
e.g. High alarm
Set: 2.0m Low Alarm Reset: 0.5m
Reset 1.8m Set 0.2m
The system will automatically configure itself as high or low alarm depending on which of
the set and reset entries has the higher value.
Note that in distance measurement mode set by Pr 1.0, the highest value is furthest from the
transducer.
The relays are controlled using parameter section 8.0 as follows: -

2. Do not include alarm
function relays in duty/standby routines.
Duty assist
pumps. Duty standby
is where pumps are switched on by set point, and kept on to assist earlier
is where only one of the pumps specified for duty can be on at a
time, i.e. when the set point for the second pump is reached and it switches on, the
first pump will switch off.

Description
The turn-off points for the pumps can all be the same, or they can be different
depending on the chosen "Set" and "Reset" values for each relay – unless using
alternating sequence at Pr.9.1.
SECTION 3
9.7 Run On Time
(0000)
Ref: MINIFLEX LR MANUAL Rev. 0 27
Pr.9.3 Exerciser (D = 0000)
To use this facility, first select alternating duty options 9.1.2 or 9.1.3 in Pr.9.1,
depending on the number of pumps installed.
Enter the number of starts assigned to Pump 1 before the sequence switches to allow
the other pumps to be exercised in turn.
Pr.9.4
Tolerance (D = No Tolerance)
In applications where a greasy topped liquid is being pumped, problems may occur
due to build-up of grease at the levels where pumping starts. It is usually necessary
for this to be cleared manually. To avoid this, varying the "turn on" point for the
pumps by ± 10% of the set point value causes the build-up to occur over a larger area,
significantly reducing the maintenance problem.
Select the tolerance setting from the following list.
Options displayed
9.4.1 No Tolerance No tolerance applied to pumps
9.4.2 Tolerance On Toleran ce applied to all pumps
Description
NOTE: The programmed pump “reset” points must be outside the 10% tolerance
zone and outside the blanking distance Pr.4.0.
Pr.9.5
Maintenance (D = All pumps in)
SECTION 3
The removal of one pump for maintenance can necessitate a great deal of
readjustment to ensure correct control. Pr.9.5 simplifys this by allowing one pump to
be removed without affecting the control levels. Pumps are re-assigned downwards
so that the highest level is not used, therefore, normal control levels are maintained
for lower level settings.
Select the pump maintenance sequence from the following list.
Options displayed
9.5.1 All pumps in All pumps in
9.5.2 Drop out pump 1 Drop out pump 1
9.5.3 Drop out pump 2 Drop out pump 2
9.5.4 Drop out pump 3 Drop out pump 3
Description
NOTE: a. The system assumes that the lower numbered pumps turn on first.
b. CAUTION - A PUMP NOT INCLUDED IN AN ALTERNATING
SEQUENCE BUT PROGRAMMED INTO THE FIXED PART OF
THE SEQUENCE WILL BE SUBSTITUTED INTO THE
ALTERNATING SEQUENCE TO REPLACE A PUMP DROPPED
OUT.
c. This feature should not be used if the relays are being used for a
mixture of pump control and alarm functions.
Ref: MINIFLEX LR MANUAL Rev. 0 28
SECTION 3
Pr.9.6 RunOnIntervl Pump Run-on Interval (D = 0.00)
When submersible pumps are used, it may be necessary to pump down occasionally to
clear the sludge from the bottom of the well. This feature is controlled by Pr.9.6 and
Pr.9.7. Once in every interval defined by Pr.9.6, the pump will run-on for the time
period defined by Pr.9.7.
Enter the time interval in hours between each run-on cycle.
Pr.9.7
Pump Run-on Time (D = 0)
Enter the pump running time in seconds. Maximum 120 seconds.
Only one run-on cycle occurs per interval as set by Pr.9.6.
NOTE: a. Caution is required when choosing a value for pump run-on time,
as extended pump run-on can lead to cavitation, causing air locks or
pump damage.
b. As overflow can occur, do not use pump run-on for pump up
operation, set Pr.9.6 and Pr.9.7 to zero.
c. Care should be taken if pump sequence and pump run-on are defined
together, as pump run-on will be assigned to the last pump to turn
off, which could be any of those in the sequence.

COMMISSIONING FAULT FINDING
WARNING! FAULT FINDING SHOULD BE UNDERTAKEN
ONLY BY SUITABLY TRAINED PERSONNEL.
Basic Hardware
A) The display is blank or frozen, the leds are unlit and the neon does not fire:-
1. Ensure that power is being supplied to the board, and that it is correctly wired.
Refer to figure 3, on Page 3.
2. Check fuses F3 (ac) and F4 (dc)
3. Check that the supply voltage is within specified levels (See Section 1 Page 3).
A large voltage drop can cause the unit to lock and show last distance or level
reading.
B) The fuse blows continuously:-
1. Power down and fit a new fuse – refer to Page 3
Remove all connection blocks except AC power TB6 or DC power TB1.
If fuse does not blow on power up insert each terminal block until fault
reappears.
Check wiring of this terminal block.
2. Check that the power supply is within specified limits -refer to Page 3.
3. Check the enclosure for metal debris which may be under the lower PCB.
C) The system powers up, but displays garbage:-
1. Power down then check that an EPROM is fitted at U2 and that it is firmly in
place.
D) The display is blank:-
1. Power down then check that a jumper link is fitted on 3 pin link LK1 at the
side of the display on the top PCB going between the centre pin and pin W.
E) The display appears faded or too dark:-
1. Adjust contrast pot P1.
Ref: MINIFLEX LR MANUAL Rev. 0 43
SECTION 5
F) The display shows 'LOSS OF ECHO':-
1. Check the transducer wiring and connections to the instrument. Note that
different connections are used if a temperature compensated transducer is
connected. See Figure 3, Page 3.
If the transducer cable has been extended as per Page 8, disconnect and
remove the transducer and connect it direct to the Miniflex LR. If the unit now
operates, recheck the extension cable connections and routing, avoiding power
cables. Re-install the transducer checking that its aim is perpendicular to the
target surface.
2. Check whether the neon light on the bottom PCB nearest terminal 1 is
flashing. If it is proceed to number 3, if it is not then:-
a: Disconnect the transducer: If the neon now lights then there is a short
circuit in the cabling.
b: If the neon does not light the transmission fuse may have blown.
Check F1 T80mA fuse on the bottom PCB.
c: If the unit still shows 'LOSS OF ECHO' check that you can hear the
transducer "clicking" when close to the ear.
d: If the transducer does not click proceed to 5.
3. Is there a target within the empty distance specified in Pr.2.0? This is
particularly important if temperature variations are experienced and no
compensation is applied.
4. Is the vessel empty with a conical, parabolic, sloping or spherical bottom?
This commonly causes loss of echo if the transducer cannot be mounted
over the centre of the vessel. When the vessel becomes empty the pulse from
the transducer hits the sloping sides of the bottom section and the signal is not
reflected back to the transducer. Under this condition the display will indicate
'LOSS OF ECHO' but the failsafe designation will operate until product
returns and the system will automatically recover and track level. If the
transducer cannot be mounted centrally, the problem may be overcome by the
installation of a target plate.
5. Connect a known good transducer to the instrument and check the operation.
If the known transducer gives a good signal check the instrument’s gain by
pressing the ' ' key. The number displayed ranges from 0.1 – 100, the lower
the number the greater the signal strength.
If the gain figure is 50 - 100 check the surface level for foam or other
materials which may float in and out of the beam and cause poor echoes.
Ref: MINIFLEX LR MANUAL Rev. 0 44
G) The keypad fails to respond:-
1. Check for correct alignment of connection from keypad to main board.
2. Check that key press sequence is valid; refer to Page 11.
3. Power down unit and wait 5 seconds. Power up and immediately press 'M'.
This should result in 'Program Mode' being displayed. It is now advisable to
reset to your original default program, Page 15.
H) Analogue output is unstable:-
1. Connect a test meter in series with your external wiring.
Can the fault be seen on the test meter? If YES, then use Pr.11.3 to set a stable
value into the current loop.
If the output is still unstable disconnect external wiring and connect a meter
across terminals 12 and 13 and repeat Pr.11.3 test.
If the output is now stable check wiring and meters
I) Analogue has no output:-
1. Check programme value at Pr.11.1
2. Insert a test meter in series with the output. Under Pr.11.3 select a fixed
output. If still no output, connect a test meter directly across terminals 12 and
13, repeat test under Pr.11.3. If no value is read at terminals 12 to 13 contact
Hycontrol.
J) Analogue output is less than 20 at maximum display reading:-
1. The load attached to the output may be too high. To check this disconnect all
the external wiring and see if it now reads 20. The output is capable of driving
20mA into 750 Ohms.
K) Analogue output does not correspond to application:-
1. Check that the correct options (Pr.11.1, 11.2 and 11.4 ) have been selected.
2. Check that the correct span (Pr.3.0) has been input, this is the value over which
the analogue will be spanned unless a separate entry has been made at Pr.11.4.1
and 11.4.2.
SECTION 5
Ref: MINIFLEX LR MANUAL Rev. 0 45
L) Reading on display and outputs stay high:-
* This is usually caused by return echoes from close-in obstructions.
1. Check for obstructions. If the transducer is mounted on a standpipe, check for
rough edges at the connection with the vessel, refer to figure 6 Page 7.
2. If there are no close-in obstructions ensure that the iso lation kit is fitted on the
transducer and that the transducer is mounted correctly. The isolation kit
should enable the transducer to move slightly, it should not be solid. (Not
applicable to flanged transducers.)
3. Check the entry at Pr.4.0, Blanking distance, and return it to 0.5m if reduced
from factory setting
4. May be caused by rate of change, Pr.5.0 being too small.
M) Reading is lower than expected:-
1. Check that Pr.2.0 and Pr.3.0 are correct for the application
2. It can be caused when the level rises into the blanking zone. The system can
then lock on to a multiple echo, and may continue tracking the multiple when
the level decreases. Using check search Pr.12.8 should rectify this situation, but
preventing the level entering the blanking zone is the preferred solution.
3. It can also be caused by the level moving at a much faster rate than is allowed
for by the defined rate of change (Pr.5.0). To solve the problem the rate of
change value should be increased to more closely match the real rate.
N) Reading changes in steps:-
* This is usually caused by the rate of change value (Pr.5.0) being too
small to keep up with the process.
1. To rectify, increase the value of Pr.5.0 to match the rate of change of level.
O) The display is inaccurate:-
1. The empty distance (Pr.3.0) of the vessel may be incorrectly set.
2. The dimensions of the vessel or flume may be incorrect, as may the values of
maximum flow, volume or mass conversion.
3. The system m ay require temperature compensation.
4. The application may include vapours that significantly change the speed of
sound.
SECTION 5
Ref: MINIFLEX LR MANUAL Rev. 0 46
P) Temperature compensation error:-
1. The position of the transducer/temperature sensor is important to prevent
heating by sunlight and convection currents. Also the sensor should be in a
free-air vented position if possible to prevent hot-spots.
NOTE: The sensor compensates only for temperature variance, it is not expected to
accurately measure the actual temperature.
Q) Temperature reads 20ºC all the time:-
1. Check the transducer wiring and connections to the instrument. Note that
different connections are used if a temperature compensated transducer is
connected. See Figure 3, Page 3.
2. Check fuse F2 T80mA.
R) The boards hums loudly:-
* Usually vibration from the transformer.
1. Check the mounting screws for tightness.
S) Relays not switching:-
1. Check the programmed relay designations and settings at Pr.8.1 - Pr.8.3
Functions can be tested under simulation using Pr.12.5 (Not differential).
2. Check contact continuity at the terminals 14 - 22.
WARNING: It is recommended that all external controls, alarms etc. are
disconnected before performing the above tests.

APPENDIX 1
LINEARISATION
VESSELS OR FLUMES
This feature allows volume conversion to be applied to irregular shaped vessels and flow
measurements to be made on open channels, providing that level/volume/flow relationships
are known.
The system allows the entry of a volume or flow profile with up to 24 points of level or head
to be entered into memory, that is then used to produce the required flow or volume values
when in 'RUN' mode.
Before proceeding it is useful to write down a table of the point numbers and 'Level / Head in
Metres' with the corresponding ‘%Volume / % Flow’ values, to facilitate programming.
VOLUME
The custom volume table is selected in Pr.6.1.8. The profile is level in metres, against
percentage of the total volume. See example on page 50.
FLOW
The custom flow table is selected in Pr.7.1.8. The profile is stored as head in metres, against
percentage of the total flow. See example on page 52.
PROCEDURE
The procedure uses a 24 point curve to map the profile, but all 24 points do not have to be
used.
Head or Level (m)
% Flow or Volume
The profile data is input into Pr.6.1.8 for volume and Pr.7.1.8 for flow. The values can be
displayed and changed as required.

Custom table - Inputting Values
When inputting a value for the first time or after a reset the initial value will be displayed as
_ . _ _ _ or _ _ _ . _.
Selecting either the ‘ ’or ‘ ’ will display 0.000 allowing you then to enter the head or
level in metres. The decimal position is fixed and cannot be changed.
For volume, both Level (Metres) and Volume (%) figures should be entered up to the
required number of points you wish to map.
For flow, both Head (Metres) and Flow (%) figures should be entered up to the required
number of points you wish to map.
After entering each value, press the ENT key to accept the value and display the next point to
be entered.
To finish entering the data points press the M key.

PARSHALL FLUMES
The OCM flow exponent (Pr.7.1) has been expanded to include 10 Parshall flume profiles.
The data for the selected flume is loaded into the flume mapping system (Appendix 1) from
tables held in memory.
Maximum head is entered in Pr.3.0 and the associated maximum flow in Pr.7.3. If one of the
values is known, the other can be found in the flume tables or by calculation from :
Flume Size -

WIRING DIAGRAM FOR SYNCHRONISATION OF INSTRUMENTS
If two or more instruments are situated close together or the transducers beam profile
overlaps there is a possibility they can interfere with each other.
Instruments located
in close proximity
MASTER
SLAVE
Potential problem application with two instruments located close together.
To solve this problem, connect the sync and shield terminals of each of the units in close
proximity to each other as shown below.
To program one instrument as master give it the ID number 1 (Pr 12.6 = 1) then set each of
the attached instruments as slaves (Pr. 12.7 = Slave) with consecutive ID numbers, up to a
maximum of 5.
