7.4 Start-up procedure
The following points should be checked before the initial start-up:
•
Correct installation of the measuring point
•
Correct alignment of the polarisation
•
Correct connection between the sensors and evaluation unit
•
Heat-up time of at least five minutes
The parameters are set via the 7-segment display for optimal measuring value output. It must first be ensured
that the receiver detects the signal from the sender. For this, the beam path between the units must be free
and menu items 3 + 4 set so that LED P1 lights up (no material detection).
Once it is ensured that the sender and receiver are detecting, the settings for the motion detection can
be made in menu 1 + 2. The motion detection is performed during the process and must be set so that
the current material is detected in the process (LED P1 lights up). After the motion detection is set, we
recommend checking again whether the receiver detects the signal from the sender during the process
(Menu 3+4, LED P1 lights up).
The microwave barrier must then be interrupted completely with the material to be measured. Once the
beam path is interrupted, it is necessary to check at menu items 3 + 4 that LED P1 has switched off (material
detection).
Once the process parameters are set, the switch-off delay of the relay and open collector output can be set at
menu item 5. In menu items 6 + 7, it is then necessary to select the desired switching response for the relay
and open collector output. For a better overview, the status LED P1 can be assigned to the state of the relay
contact or the open collector at menu item 8.
The open collector output must be supplied actively with a voltage (max. 30 V, 20 mA).
Once all parameters are set properly, these must be saved by pressing the + button at menu item 9.
The initial start-up is now completed, allowing the ProGap 2.0-BS to alarm reliably as soon as
the selected limit level is reached.
