Loc
Parameter lock
If parameter Loc is set to other values than 808, then only field parameters in the
range of 0 to 8 and parameter Loc itself can be set. When parameter Loc is set to
808, user can set all parameters. Parameter Loc provides several operation
privileges. When user has completed setting some important parameters such as
input and output, parameter Loc can be set to other values than 808 in order to avoid
field operators’ accidental modification of some important operation parameters. See
the following:
1.
for AI-518 series instrument
Loc=0,
allowed to modify field parameters and setpoint.
Loc=1,
allowed to view field parameters, and to set setpoint. But the modification
of field parameters (except parameter Loc itself) is not allowed.
Loc=2,
allowed to display and view field parameters, but the modification of field
parameters and setpoint (except parameter Loc itself) is not allowed.
Loc=808,
configuration of all parameters and setpoint is allowed.
2.
For AI-518P series instrument
Loc=0,
allowed to modify field parameters, program value (time and temperature
value) and program segment number StEP.
Loc=1,
allowed to modify field parameters and StEP value, but the modification
of program is not allowed.
Loc=2,
allowed to modify field parameters, but not allowed to modify StEP value
and program.
Loc=3,
only allowed to modify parameter Loc itself, all other parameters,
program and StEP value can not be modified.
Loc=808,
allowed to set all parameters, program and StEP value.
Note:
that 808 is the password of all AI series instrument. In application the
instrument should be set to other values to protect from modifications of parameters.
Meanwhile the management of production should be enforced to avoid arbitrary
