Operability

By using frequencies in the 24 GHz range, the material flow of products with low attenuation can be
detected, even if the product quantities are low� The calibration options for the FTR20 flow indicator
offer the necessary flexibility to ensure that the device can be easily adapted to the application:
• Adjustable sensitivity
• Switchable limit signal function:
- Switch point exceeded = max� safety or
- Switch point not reached = min� safety
• Adjustable switching hysteresis (not for current output)
• Switching delay (not at current output):
- 100 ms to 20 s
- Response and drop-out delay, can be selected separately
• LED field strength indicator as an adjustment and positioning aid
The FTR20 is configured using the function selection and the two operating keys. By doing so,
calibration to a sensitivity necessary for clear and unambiguous material flow identification of the
products is carried out. If the movement of the bulk solids is sufficient, the FTR20 responds with an
output signal to this effect.
The parameter configuration is stored internally and is retained even after the supply voltage is
disconnected� No other operator intervention is necessary during operation� The adaptation to the
application is required during initial installation only� However, subsequent changes can be made
and stored at any time�

Display
The signal strength as well as the configured values (in the function selection) are displayed locally
using a bar graph display� In addition, a green LED indicates that the device is ready to operate
(supply voltage is present) and a yellow LED displays the status of the switch output (LED off: relay
in rest position, solid-state relay high-impedance)�
