4 Operation
4.1 Startup
First a transducer must be connected to the VD6 according to chapter 3.4. As soon as
the mains power supply is connected, the display will show the following information:
-
display test (all segments)
-
firmware version
- selected transducer type
-
actual pressure.
Then the instrument is in measurement mode.
If the controller is configured start active - see chapter 5.4 (start mode "run") -,
the VD6 will actuate the two relay outputs simultaneously with the display of
actual pressure.
Otherwise the change-over relays are in rest position.
Key Description:
Change between measurement mode and the adjustment of setpoints,
hysteresis or gas correction factor.
Measurement mode: start/stop controlling (see also chapter 5.4)
Adjustment mode: confirm settings
Increment values in adjustment mode
Decrement values in adjustment mode
4.2 Measuring Absolute Pressure
In measurement mode the VD6 display shows the actual absolute pressure.
Pressure reading is numerical above 1 mbar (Torr, …) and exponential below.
The state of the switching outputs is indicated by LEDs SP1 and SP2, which are on as
soon as the corresponding relay is switched on.
