Ref: REFLEX/SCANFLEX MANUAL
EDITION 1: JULY ’97 35
EXAMPLE 2
Reflex as a Single Point Level Instrument with Volume Conversion
Application is identical to Example 1 but tank contents when 18 metres deep is 8000 tons and
a temperature compensation probe is fitted.
Programme exactly as Example 1 with the following additions:-
Pr.37 = 2 Temperature sensor enable
Pr.40 = 1 Flat bottomed vessel and percentage of span
Pr.43 = 80 Display conversion = full capacity
+
100
Pr.72 = 0 No decimal places.
EXAMPLE 3
Reflex as a Multipoint Scanner
Application is the same as Example 1 but with seven 7 identical tanks to be monitored.
The system must include a Reflex Controller, a Multiplexor SM-10, an Analogue Module
SA-10 and a Relay Module SR-10.
After entering programme mode ensure that the display is showing 'POINT 01' before detail
programming starts.
Pr. 1 = 7 Multipoint application with 7 transducers
Pr. 2 = 1 RXM19 long range transducer
Pr. 3 = 2 Level measurement in metres for POINT 01
Pr. 4 = 20 Empty distance 20 metres for POINT 01
Pr. 5 = 18 Span 18 metres above empty level for POINT 01
Pr. 6 = 1.0 Blanking zone into which level must not rise for POINT 01
Pt. 7 = 10 Rate of Change for POINT 01
Pr. 8 = 1 This will designate Relay 1 on the SR-10 as level alarm for
all Points.
Pr. 9 = 17 Relay 1 set point for POINT 01
Pr.10 = 16.75 Relay 1 re-set for POINT 01
Pr.11 = 1 This will designated Relay 2 on the SR-10 as level alarm for
all Points.
Pr.12 = 2.0 Relay 2 set point for POINT 01
Pr.13 = 2.25 Relay 2 re-set for POINT 01
Pr.23 = 3 Designates that Relay 1 will failsafe Hold on all Points
Pr.24 = 3 Designates that Relay 2 will failsafe Hold on all Points
Pr.28 = 3 Designates that on all Points the Analogue Output will hold
last value on any Point which loses echo.
Pr.29 = 60 Designates that the LOE group alarm, Relay 3 in the Controller,
will operate after 60 seconds.
Pr.30 = 1 Designates that the Analogue Output for all Points will be
4-20ma
Pr.51 = 3 Defines that there are 3 modules attached to the Controller
i.e. SM-10, SA-10 and SR-10.
