8 Commissioning
This chapter briefly describes the most important aspects of the commissioning
of a Q1.
All Q1 parameters are listed in the Annex (Chapter 11) to this documentation.
8.1 Parameter protection against unauthorised access
The functionality of the Q1 can be completely configured via a parameter data
record. Unauthorised persons must be prevented from changing these
parameters. In order to guarantee this protection, the gas-lab Q1 is provided
with a two-level security system consisting of the Calibration lock (official
safeguarding) and the Locks (user lock, password protection).
8.1.1
Calibration lock / Calibration switch
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 control purposes the device generates hint H800: Calibration
lock open when the calibration switch is open.
Opening the calibration switch 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 parameterisation and opened or closed via the operator
panel. Open locks allow the user to access specific parameters or actions that
can be edited 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.
