Example for ON:

FC01-LQ with relay outputs (option R2):

• LIM1 - LIM1COM = closed

/LIM1 - LIM1COM = open

FC01-LQ with transistor outputs (option T4):

• LIM1E - LIM1C = switched

Example 2: Switch-on value higher than switch-off value

Example for ON: as described in example 1 (fig. 23)

With limit switch 1 set for flow rate and a flow volume/time unit selected in menu DISPLAY
SELECT, and when setting the switch-on and switch-off value, the pertinent flow volumes will
also be indicated.

6.3 Limit switch 2 - switch-on value (menu option: LS2 ON = ......)

Limit switch 2 - switch-off value (menu option: LS2 OFF = ......)

See limit switch 1!

6.4 Scaling factor (menu option: FLOWSCALE)

The scaling factor influences flow rate indication.

The factor, which may be set between 0.01 and 9.99, allows flow rate indication changes
(increasing or reducing the measured value in the display).

For example, the scaling factor may be used to indicate the average flow rate in the pipeline
rather than that available at the sensor.
