ATTENTION: One software key protects one or more run time
parameter groups so that when the software key is set, it is
possible to modify the run time parameters of all groups.
The software protection will be automatically restored when the
instrument comes back to the "normal display mode" (by
"MENU" push-button pressure or by the time out).
The parameter monitoring and modification are subjected to a
time out (see “t.out” [C.I10] parameter) after that, the display
returns in “Normal display mode” and the eventual modification
of the last displayed parameter will be lost.
CONTROL PARAMETERS MODIFICATION
By “MENU” push-button it is possible to start the run time
parameter modification by selecting desired run time parameter
group.
During the run time parameter modification, the upper display
shows the selected parameter group, the lower display shows
the mnemonic code of the selected parameter while the central
display shows the value or status assigned to the selected
parameter.
CONTROL PARAMETERS
The run time parameters are common for programmer and for
controller mode (exception made for group P and group 9
available only when the instrument operates in programmer
mode).
CONTROL PARAMETERS PROTECTION
Moving from one run time parameter group to another, the
instrument will show, at first, the group number (on the upper
display), the mnemonic code (on the lower display) and the
security status (on the middle display) of the group.
The possible security status are:
Enb
= the parameters of this group are not protected and they
may be modified;
inh = the parameters of this group are ever protected and
they cannot be modified
KEY = the parameters of this group are software protected.
In this case, using “ s“ and “t” push-button set a value
equal to the security code programmed during the "Run
time security code " (see page 24) and then push
“FUNC”.
If the programmed value matches the security code, the
parameters of this group can be modified otherwise they
remain protected.
