LED indicator bar — flow monitoring
Quick-Teach mode — LED indicator bar
In Quick-Teach mode, the LED indicator bar refers to a fixed indicated range that spans around
the taught-in FLOW switching point. This indicated range covers approximately 5 % of the total
sensing range. The switching point set in Quick-Teach mode is indicated in the LED bar by a yel-
low LED; deviations from this switching point are indicated in 0.5 % increments by green LEDs.
Green LEDs to the left of the yellow switching point LED indicate that the switching point is be-
ing undershot, green LEDs to the right of the yellow switching point LED indicate that the
switching point is being exceeded.

Green LEDs: Indicate the flow deviation proportional to the set
switching point (yellow LED).
Flow speed below the switching point:
Flow speed above the switching point:
MAX/MIN mode — LED indicator bar
The FLOW switching point is set as a percentage value within a previously taught-in MAX/MIN
indicated range. The switching point (yellow LED) and flow speed (green LEDs) are displayed in
the LED bar by 11 LEDs proportional to the indicated range. Flow values that deviate from the
FLOW switching point are indicated in 9.1 % increments by green LEDs. Green LEDs to the left
of the yellow switching point LED indicate that the switching point is being undershot, green
LEDs to the right of the yellow switching point LED indicate that the switching point is being
exceeded.

LED indicator bar — temperature monitoring
To display the temperature: Press and hold [SET] in display mode.
The TEMP switching point is set as a temperature value within a fixed indicated range of
-40 °C…+180 °C/-40 °F…+356 °F. The switching point (green LED) and media temperature (yel-
low LEDs) are displayed in the LED bar proportional to the indicated range (0…11 LEDs:
-40 °C…+180 °C/-40 °F…+356 °F). Media temperatures deviating from the TEMP switching
point are indicated in 20 ° increments by yellow LEDs. Yellow LEDs to the left of the green
switching point LED indicate that the switching point is being undershot, yellow LEDs to the
right of the green switching point LED indicate that the switching point is being exceeded.
