6.2 Start-up and normal operation

If the device is supplied with electric power, the start-up procedure begins automatically. The first
step is the booting of the computer and the heating of the sensor block. The current temperature
of the sensor block (called TSB) is displayed during this time on the display that appears.
If the TSB has reached the operating range at 70°C, the delay and flushing times are also
displayed and an automatic operational calibration is executed. After this procedure the device
switches automatically to normal operation "Analysis".
The devices are supplied with a factory parameter setting, which enables
the device to be commissioned with low accuracy deviations without
further changes.
The factory parameter setting also defines the start up behavior described
above. For change requests, see chapter 8, or get in contact with the Elster
GmbH.
With the factory settings, the raw values from sensors are processed and reported as well as
monitoring and recording tasks are implemented. The power consumption of the heating is
reduced. Only the power which is required to maintain the temperature at measurement
conditions is used for heating after the start-up.
This function (normal operation) is displayed on the screen of the device. The measuring system
is applied to various natural gases and measures these gases in continuous flow every second.
The GasLab Q2 has an extra heater for use at temperatures around the freezing point and below.
To protect the device against overheating, this function is only available up to a housing
temperature of + 13 °C. With the factory parameterization, the extra heating is automatically
switched on at 0 °C, with a switching hysteresis of 2 °K. The heating function is set and modified
via the parameterization software enSuite. Please see chapter 8 for more details.
Perform all work in the specified order to avoid any damage and disturbance situations on the
device.
Steps for start-up
1. Check the condition of the system and the connections.
2. Open the operational calibration gas cylinder (setting 0.2 MPa (g)).
Open the process gas (PG) (setting 0.15 – 0.5 MPa (g)).
3.
Switch on power, it automatically starts the start-up and heating process. The built-in
4.
operation panel is activated. The heat up time of a cold device can be up to an hour.
After the TSB reached the operational value, the software performs the further
5. parameterized steps (see chapter 8). The final step is the measurement mode
"analysis", this is displayed on the screen.
Check the gas flows into the flow meters and customize them, if in the valid range, see
chapter 6.2.1. Also check the settings for calibration gas mixture and automatic
6.
operational calibration, correct them if nessesary. See chapter 8.3.4
Q2 now works continuously and commissioning is complete.
