CONFIGURATION LOCK-OUT
Lock-out menu
The following configuration access can be locked-out:
•
Setpoint 1 configuration (
SEt1
)
•
Setpoint 2 configuration (
SEt2
)
•
Input configuration (
InP
)
•
Display configuration (
dSP
)
In each case lock-out is activated by selecting “
yES
” option and
deactivated by selecting “
no
”.
Setpoints 1 and 2 configuration lock-out is available only when relay
output is installed.
If relay output option card is uninstalled, the instrument keeps
setpoints last configuration in memory, though it can not be visualized.
There will be no need to reconfigure setpoints lock-out when relay
output option is again installed if the same configuration is required.
Once the instrument programming is completed, if there are
parameters that are going to be frequently changed, a partial lock-out
is recommended. A total lock-out is recommended when configuration
parameters will be constant for a long time.
Changing default security code and keep new one in a safe place is
also strongly recommended.
In order to prevent accidental or undesirable modifications of instrument parameters, a selective or total
configuration lock-out is available. By default the unit is delivered unlocked, giving access to all programming
levels. Once in this menu, the first option will be to choose between lock-out level setting (“
LiSt
”) or security
access code changing (“
CHAn
”).
If “
LiSt
” option is selected, display will show momentarily
“
tLoc
”. Total configuration lock-out is activated by
selecting “
yES
” option before the unit goes back to
RUN
mode.
When total lock-out is set, no data can be
entered or modified
, although it will still be possible to
visualize all programmed parameters. Under these
conditions when entering main menu, initial indication will
be “
dAtA
” instead of “
Pro
”.
On the other hand, when “
no
” option is selected, routine
move on to next step to configure a partial lock-out.
When a partial lock-out is set, only non-locked data
can be entered or modified
. Under these conditions
when entering main menu, initial indication will be “
Pro
”.
