Chapter 4—System Configuration and Commissioning58 Power Xpert C445 Global Motor Management Relay MN042003EN—October 2016 www.eaton.comParameter Lock FeaturesThe C445 supports various protection feature options for writing to its parameters,including:1. Administrator password Lock2. USB lockout password3. Running Lock optionNote: The Administrator password and Running Lock option also applies to theWeb Pages if an Ethernet Card is installed. The Web Pages also allow fora separate password to be set to prevent access to the parameters from theWeb Pages.Administrator Password LockThe Admin password protection prevents anyone who has not logged into the system withthe proper password from modifying any configuration parameters. All parameters may beread, but not written.Out-of-box, there is no active Administrator password protection.The Administrator password is a 32-bit value that can be set as a Hex, ASCII or decimalvalue that fits in 32-bits. Whatever format is used to set the password will need to be usedwhen entering the password as well, to be sure it is correct. For example, if the passwordis set by writing an ASCII value of 1234 and later someone tries to unlock it with a decimalor hexadecimal value of 1234, it will not work.The Modbus register addresses that store the 32-bit Administrator password are 5000/5001. The Modbus register addresses that must be written to when logging in to a systemwith an Administrator password set are 5002/5003.Reading the value at register 5010 will indicate if an Administrator password is set in thedevice or not. If a value of 1 is read, this indicates that an Administrator password is active.A value of 0 indicates that an Administrator password is not currently active.When 5000 and 5001 each contain hexadecimal zeros (0x0000), this means no passwordis set. This is also what must be written to these registers to clear a password. The onlyway to write to these registers if there is a password set is to first log in. Then once loggedin, hexadecimal 0s can be written to these register to clear the password. A “Reset toFactory Defaults” also clears/resets the password. Since this can be accomplished usingthe button on the Base Control Module, a C445 with an unknown password can berecovered in this manner, but will need to be reconfigured. All parameters will have beenset to factory defaults, not just the Admin password.The Admin password can also be set using the Power Xpert inControl Software Tool,under the Security category. Parameters that are locked in Admin mode are indicated inAppendix D Modbus Register Map
