REFLEX/SCANFLEX
PROGRAMMABLE LEVEL CTROL SYSTEM
INTRODUCTION
The REFLEX/SCANFLEX Programmable Level Controller is capable of monitoring the level
of liquids, powders and solids in vessels up to 50 metres deep, depending on the type of
material they contain.
The instrument is programmed by the user, who can select either;
Single point monitoring (REFLEX mode) for one transducer or
Multipoint monitoring (SCANFLEX mode) for up to 10 transducers.
The REFLEX/SCANFLEX will operate with either short range transducer of the RXV15
family or long range transducer of the RXM19 family.
The principle of operation of the REFLEX/SCANFLEX system is to use ultrasonic pulses
which are transmitted directly, or via a Multiplexor, to the transducer mounted at each
measurement point. Echoes are reflected off the surface of the material being monitored, back
to the transducer.
The time period between transmission and reception of the echo is directly proportional to the
distance between the transducer and the surface being monitored. A microcontroller computes
this time period for all echoes received and analyses them to determine which is the correct
reflection from the material surface. It uses this data as the basis for giving control outputs and
displays in usable engineering units.
REFLEX/SCANFLEX is capable of the following functions:
Level Measurement
Volume Measurement
Distance Measurement
When used as a REFLEX single point instrument the controller is connected directly to the
transducer.
When used as a SCANFLEX in its multipoint mode the controller is connected to the
transducers via a Multiplexor. Additionally, relay and analogue output modules can be added
to the system and individually programmed for each point.

REFLEX - AS A SINGLE POINT INSTRUMENT
Transceiver Mounting
Undo the 6 quarter turn screws on the front panel and open the hinged door to expose the
mounting holes.
Mount the unit on a flat surface and secure it via the 4 mounting holes moulded in the
enclosure. 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.
Remove the required number of hexagon blanking plugs from the bottom of the enclosure and
replace them with appropriate conduit hubs or cable glands to maintain the I.P. rating.

INSTALLATION
REFLEX - AS A MULTIPOINT INSTRUMENT
System Configuration
The REFLEX controller can be used as the heart of a SCANFLEX System which will monitor
and control the level in 2 to 10 separate vessels. The transducer for each vessel is connected to
the controller via a 10 point Multiplexor SM-10. A full description of the Multiplexor and
PCB layout is shown on Page 58 to 61.
The Controller will output an analogue signal proportional to level or distance for each point as
it is scanned, but if a continuous mA signal is required for each point then an Analogue Output
Module SA-10, must be connected. A full description of the Analogue Output Card and PCB
layout is shown on Page 65 to 67
When used in the multipoint Scanflex mode the 5 relays in the Controller are pre-assigned as
Group Alarms and show the following:-
Relay 1 Indicates that Relay 1, on one of the points being monitored, has operated.
Relay 2 Indicates that Relay 2, on one of the points being monitored, has operated.
Relay 3 Indicates a loss of echo on one of the transducers.
Relay 4 Indicates that there is a fault in the communications with a module.
Relay 5 Indicates that the instrument is in Programme Mode.
To provide two separate alarm or control relays for each point a Relay Module SR-10 must be
connected.
A second Relay Module can be added, to provide 2 more alarms or relays for each point. A full
description of the Relay Module and PCB layout is shown on Pages 62 to 64.
Scanflex Configuration General
The modular approach to the design of the SCANFLEX system allows a choice of different
system configurations to be built. The individual modules required to build each system can be
mounted remote from each other. The controller is linked to the Multiplexor with RG62AU
cable and communication between the Controller and all modules is via a single RS485 cable.
Suitable cables include Belden 8451, Alpha 2461 or equivalents.
A little care in the selection of the location for the individual modules can considerably reduce
the cost of cabling.
i.e. The Multiplexor Module should be close to the transducer.
The Analogue Module should be close to where the outputs are required.
The Relay Module should be close to the alarms or controls it operates.
The maximum distance between the Controller, through the Multiplexor, to each individual
transducer, should not exceed 300m.
The Relay and Analogue Modules can be up to 2000m from the Controller, or greater if
repeater modules are used on the RS485 communications.

INSTRUMENT MOUNTING
To install the REFLEX/SCANFLEX Controller and the associated Scanflex SM-10
Multiplexor, SA-10 Analogue Module, and SR-10 Relay Module, if required, follow the
guidelines below.
Reflex/Scanflex Controller See Fig. 1
To install this follow the instructions for mounting the Reflex transceiver as shown on Page 2.
Modules SM-10, SA-10 and SR-10
These are all supplied in identical enclosures as shown on Page 59. Before mounting them
drill the enclosure and fit appropriate conduit hubs or cable glands.
Undo the 6 quarter turn screws on the front panel and remove it to expose the mounting holes.
Mount the unit on a flat surface and secure it via the 4 mounting holes moulded in the
enclosure. 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.
Scanflex Multiplexor SM-10
One of these modules must be fitted in all multipoint systems.
For economy of cabling put the Multiplexor as near the transducers as possible.
See Page 9 for ELECTRICAL CONNECTIONS.
Scanflex Analogue Module SA-10
This is an optional requirement.
The Analogue Module should be located close to where the analogue outputs are to be used or
displayed in order to reduce the wiring to a minimum.
See Page 10 for ELECTRICAL CONNECTIONS.
Scanflex Relay Module SR-10
This is an optional requirement.
The Relay Module should be located close to where the controls or alarms are located. If
relays are required to activate both controls and alarms, but they are located in different areas,
then a Relay Module should be mounted separately in each location as this will significantly
simplify and reduce cabling costs.
See Page 10 for ELECTRICAL CONNECTIONS.

Each Module (other than the Controller) must have an individual address number. This is set
on Switch (SW1) which is located on the upper left hand side of each Module.
The switch (SW1) on the Multiplexor must always be set to 1, with other Modules numbered
sequentially with no gaps in the sequence.
The total number of Modules connected to the Controller must be entered in Pr.51
NB - No two Module switches should be set to the same position.

Ref: REFLEX/SCANFLEX MANUAL
EDITION 1: JULY ’97 11
Transducer Installation
The positioning of the transducer and the mounting method used is important and varies with
the type of transducer, the application and the material, being monitored.
On liquid measurement applications it is important to ensure that the transducer is
perpendicular to the liquid surface and the circumstances shown on Page 49 should be avoided.
The transducer beam angle is 10 to 120included.
Transducers should be mounted in the isolation kits provided and for solids applications where
levels may not be flat due to the effects of fill or draw off points, then an aiming kit as shown
on Pages 53 or 54 should be used.
Transducers wired to the Multiplexor (SM-10) must to be connected to Point 1 first then
sequentially and without gaps. See Page 60 for terminal connections.
Each transducer is supplied with a length of integral cable, which can be extended up to 300
metres using a suitable junction box, and RG62A/U co-axial cable. The 300m is the maximum
distance from the Controller to the transducer via the Multiplexor. Transducer cable should
be separated from power cables and preferably installed in its own earthed steel conduit.
Transducer cables and temperature compensation cables can be run together.
For installation of the RXV15 series transducer in hazardous locations refer to the appropriate
National Standard.
SEE APPENDIX (1) FOR TRANSDUCER PERFORMANCE, POSITIONING AND
PHYSICAL RECOMMENDATIONS FOR STANDPIPE INSTALLATIONS.
Temperature Sensor See Page 55
If temperature compensation is required the sensor should be mounted where it will monitor
temperature changes of the air between the transducer and the material. This is usually
adjacent to the transducer, but should not be in direct sunlight.
The sensor is connected to the Multiplexor at TB2 using a 2 core screened cable connected to -
ve, +ve and SHLD for each point. The Multiplexor terminal TB3 connections SHLD, + and -,
are connected to Controller terminals 21 to 23 using the same type of cable. The total cable run
from sensor to Controller via the Multiplexor should not exceed 300m. The cable can be run
together with the transducer cable in the same conduit.
For installation of sensor type RTS-2B in hazardous locations refer to the appropriate
National Standard.

PROGRAMMING
REFLEX/SCANFLEX system needs to be programmed by the operator to produce the
required measurements and control. To do this the keypad on the Controller is used to access
parameters and enter values in each one to determine the controls required.
Principle of Programming
The REFLEX/SCANFLEX has two modes:-
a) RUN (Normal operating)
b) PROG (Programming)
In the 'RUN' mode, the instrument monitors the target, displaying values, and setting outputs
as programmed by the operator. If Scanflex multipoint operation (Pr.1 = 2 to 10) has been
selected then in "RUN" mode the instrument will automatically scan each point and update
the display in numerical sequence.
In the 'PROG' mode the operator uses the keypad in conjunction with the display to adjust the
settings for each point and to test that the unit is programmed correctly.
Security Code
The REFLEX/SCANFLEX program includes security code protection. Any operator who
knows the entry sequence can display the value of a parameter, but any attempt to enter a new
value or perform a test will result in the security code being requested.
The security code is requested by the prompt 'CODE'. If the code is not entered correctly,
then this prompt is re-displayed.
Once the code has been input correctly, it will not be required again whilst the system remains
in the 'PROG' mode.
The factory set value is 9753, but a new "customers" security code comprising 4 numerical
digits, can be entered via Pr.96 providing the operator is in program mode. The range of
acceptable values is 1000 to 9999. If an invalid code is entered the instrument will default to
a code number 1000.
The code number is scrambled immediately on entry and therefore cannot be read by an
unauthorised person.
If you forget your own new code number contact Hycontrol advising the scrambled code
number displayed at Pr.96

To Change Point No. in Multipoint Mode (i.e. Pr.1 is 2 or greater)
Select any parameter, which is a POINT parameter (not CONTROL) and press # key. POINT
No. will increase progressively until the maximum selected by Pr.01 and then return to
POINT 01.
Note that you will stay on the Point No. selected until you return to RUN mode, or press the #
key to change the Point No.
Return System to "RUN" Mode
When all parameters have been set to their required value press MODE and the instrument
will return to "RUN" i.e. normal running. (The unit will automatically return to RUN mode if
a key is not pressed within 6 mins).
USE THE KEYPAD AND WATCH THE DISPLAY UNTIL YOU FEEL COMFORTABLE
WITH ALL KEY PRESSES AND DISPLAYS.
We recommend that you now reset the system to its factory defaults as shown below, before
you begin programming the system for your application.
System Reset to Factory Defaults
1. Press MODE to display 'PROG'.
2. Press 1 to display programme sequence.
3. Change Pr. number to display Pr.99.
4. Press DSP to move cursor under '===='
5. Press 'CE' then 'ENT'.
6. Press 9753 when 'CODE' displayed. (Or your own new code number).
7. Press 'ENT'.
8. Display will show 'PRES' and 'TRES' and return to programme display.
9. Press DSP to move cursor under Pr.99
10. You can now begin programming by changing Pr.99 to the first parameter you wish to
change.
All parameters are now returned to their original factory default values as specified in this
manual.
i.e.RXM19 family and single point Reflex mode.
Before starting to programme your application we recommend that you list all parameter
numbers/values which you intend to change from their factory defaults.
For Reflex single point use Page 71.
For Scanflex multipoint use Page 72.

Manual Scanning
When used as a multipoint scanner this facility has been included mainly for commissioning
and fault finding purposes. It allows the system in the "RUN" mode to continually stay on
one point whilst checks are carried out. The normal scanning process is stopped.
When manual scan is in operation the system fault relay (Relay 4 on the Controller) will be in
alarm mode and the corresponding LED will be on.
Manual scan is enabled by programming Pr.53 = 1 and then re-entering "RUN" mode.
To select a specific point to be monitored press the relevant key 1-9 or 0, these correspond to
measuring points 1-10. To de-select manual scan set Pr.53 to 0 or power down then up
again.
NOTE:
1. When in manual scan, press "TEST" to display the gain value.
To return to normal display press the "CE" (Clear entry) key.
2. Module system status check does not operate during manual scan.
3. The unit will not automatically return to normal run mode. Reset Pr.53 to 0.

Keypad Definitions
The keypad consists of 20 keys which are used to programme the Controller. Some of these
keys also have secondary functions enabling the operator to view the results being obtained
by the instrument during its normal 'RUN' cycle.
Primary Key Functions
0 - 9 Numerical Values
w Decimal Point
— Negative value (also used to slow down simulation)
CE Clear Entry (also used to leave test functions Pr.75 to Pr.78.)
# In normal 'RUN' mode it displays unit status and in 'PROG'
mode it advances point number. (also speeds up simulation Pr.78)
MODEAlternates between 'RUN' and 'PROG' mode.
TEST In 'RUN' it displays gain and distance or shows LOE status.
'▲' Increase parameter number (also control of simulation direction).
'▼' Decrease parameter number (also control of simulation direction)
DSP Moves the cursor on the display between Pr. No. and its value.
(Changes can be made only to the data underlined by the cursor.)
ENT Enter a new value or initiate a system test under Pr.75 to Pr.78
Active Secondary Key Functions
During normal 'RUN' mode it is possible for an operator to obtain the data defined as
secondary function without interrupting normal operation, by pressing the appropriate
key, i.e.
Key 1 Relay 1. Hours energised and number of starts.
Key 2 Relay 2. Hours energised and number of starts.
Key 3 Relay 3. Hours energised and number of starts.
Key 4 Relay 4. Hours energised and number of starts.
Key 5 Relay 5. Hours energised and number of starts.
Test In 'PROG' it scrolls through parameter list and control
simulation.
DSP Displays point, mA output and temperature
To cancel secondary display press "CE"
