Signals at these inputs are only accepted if the location of control is set to PLC, All or Local
and PLC.
Scaling recorder output
Main menu > Settings > Interfaces > Scaling recorder output
Here the scaling of the recorder output can be adjusted. This adjustment is possible only
when the signal LR lin or LR log is chosen.
Example:
Upper limit value is adjusted to 10
-5
(= 10 V)
Scaled to 5 V /decade
Lower limit value consequently is 10
-7
(= 0 V)
PLC sample rate
Main menu > Settings > Interfaces > PLC Sample rate
Operation
By pressing the MENU push button Figure 12 item 13 the main menu will be displayed
regardless of the current working mode or status of the ELD500.
The main menu Figure 23 leads the operator to several sub-menus described in the following
chapters. The main menu is identical for all ELD500 models.
The next page gives an overview of the entire menu architecture Figure 23.
The overview of the menu architecture corresponds to the ELD500 WET, differing menu
points or setting possibilities for the ELD500 DRY and ELD500 FLEX are described in the
respective menu point.
Change from high to low: approve that external test leak is closed and
leak rate signal is stable.
Softkey 2: The decade of the upper leak rate can be decreased.
Softkey 3: Decrease scaling of the previously adjusted value in steps of 0.5, 1, 2,
2.5, 5, 10 Volt/decade. The complete array covers 10 V.
Softkey 5: Help text.
Softkey 6: The decade of the upper leak rate can be increased.
Softkey 7: Increase scaling of the previously adjusted value in steps of 0.5, 1, 2,
2.5, 5, 10 Volt/decade. The complete array covers 10 V.
Softkey 2: Decreasing the PLC sample rate down to the
minimum of 10 ms.
Softkey 3: Increasing the PLC sample rate to the maximum
of 100 ms.
