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.
