8 Commissioning
This chapter briefly describes the most important aspects of commissioning an EnCal 3000.
8.1 Parameter Protection against Unauthorized Access
The functionality of the EnCal 3000 Controller can be completely configured via a parameter data record. Unauthorized
persons must therefore be prevented from changing these parameters. In order to guarantee this protection, the EnCal
3000 Controller is provided with a two-level security system consisting of the Calibration lock (official safeguarding) and
the Locks (user locks, password protection).
8.1.1 Calibration Lock
The calibration lock physically consists of a sealable rotary switch on the front of the device. Open the calibration switch
by turning it anticlockwise as far as it will go. For additional safeguarding, the device generates hint H800: Calibration
lock open when the calibration switch is open.
Opening the calibration lock enables the operator to access all device parameters.
8.1.2 User Lock
The user lock consists of one (numerical) lock for each of the two contract parties and is implemented via the software.
This means that the locks are defined by the device parameterization and opened or closed via the operator panel. Open
locks allow the user to access specific parameters or actions that are editable directly at the device. All parameters being
subject to the user locks can be modified when both locks are or the calibration switch is open.
8.2 Parameterization
Use a PC to create a complete parameterization or edit existing parameters (except for a few). Create the parameter
data record using the GW-GNET+ parameterization software. The calibration switch has to be open during the import of
a complete parameterization via the DSS data interface.
Note: Please refer to Chapter 6 for brief instructions on the parameterization by means of GW-GNET+. Please refer to
the GW-NET+ online help for a comprehensive description of the parameterization program.
Operational parameters can also be changed by means of GW-GNET+ via the data interface, even if the calibration
switch is closed. In case of password-protected parameters, however, the user locks must be open.
Checking the Settings
It is possible to check the complete set of parameter settings of gas-net devices by means of the GW-GNET+
parameterization program (cf. Chapter 4.4 for brief instructions). The billing-relevant parameters of the EnCal 3000
Controller are very important. They can be invoked at the operator panel to facilitate an effective supervision of the
device configuration (cf. Chapter 4.4 for brief instructions on how to view the device configuration).
