6.5 SETTING THE SECURITY CODES

The security code setting is accessible by setting an internal dip switch (see Figure 12 below). There

are three Security levels. When each level has been assigned a code access to the parameters will be

available as follows:

• Level A: Allows access to parameters in Group 1 Only

• Level B: Allows access to parameters in Groups 1 and 2 Only

• Level C: Allows access to parameters to all Groups 1 - 5
