SECURITY FEATURES
The B 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.
