SECTION 4
MINIFLEX LR DEFAULT PROGRAMS
For each application type in the Miniflex LR there is a default program, which is
automatically loaded on first selecting a new application at Pr.1.0. Resetting the instrument
(Page 13) will load the factory default program for a typical distance measurement
application. The default settings for all 6 application types are detailed on the following
pages.
DISTANCE – Distance Measurement Mode Default Program
Changing the application to Distance Measurement or resetting the instrument, loads this
distance measurement default program into memory.
Pr.4.0 Blanking 0.500m
Pr.3.0 Operational
Span
10.00m
Pr.2.0 Empty Distance
10.00m
TARGET
This default program is created to do the following:-
To measure and display the distance between the face of the transducer and the target
in metres.
Maximum distance of 10.00m.
Rate of change of 10.0 metre/min.
No alarms.
4-20mA output proportional to distance.
This program can be easily modified to suit the required application. You should delete from
this program any unwanted entries (e.g. 8.3.4 Relay 3 L.O.E.).
Parameter Default Description
number Setting
2.0 Empty Distance = 10.00 Maximum measurable distance from transducer.
3.0 Operational Span = 10.00 The span, based on zero level.
4.0 Blanking = 0.500 Blanking zone into which target should not rise.
5.0 RateOfChange = 10.00 The maximum rate of change of target distance in
metres/minute.
8.1 Rly1 Options = 8.1.5 Relay 1 Off Relay 1 Off
8.2 Rly2 Options = 8.2.5 Relay 2 Off Relay 2 Off
8.3 Rly3 Options = 8.3.4 Relay 3 L.O.E. Relay 3 (L.O.E. Alarm – de-energises relay)
10.4 Fail Time = 600 Failsafe time in seconds
10.5 mA Fail = 10.5.3 Analogue Hold Analogue output holds on failsafe.
11.1 Analog O/P = 11.1.1 Output 4–20mA 4-20mA output fixed to span (Pr.3.0).
To simulate the program go to 12.5.2 yes then press ENT again.
