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
