SECURITY FEATURES
The C series controller has two built in security lock settings to prevent
unauthorized personnel from changing parameter settings. These
parameters are set in the Operation Mode.
The LoC1 setting affects all parameters in the controller. If LoC1 setting is
enabled, the operator will have to unlock the controller to make any changes
to the controller’s parameters.
The LoC2 setting affects all parameters except the set point. If LoC2 setting
is enabled, the only parameter that the operator will be able to change is the
set point. In order to change any other parameters, the operator will have to
unlock the control before making a change.
In order to unlock the control, the operator must depress the ENTER and
INDEX key simultaneously.
