Fault

Detail

Possible cause

Item to check / Recommended action

The push
buttons do
not work

The push
buttons do not
react.

Key-lock mode is
activated.

Press a button and check to see if the [LoC] appears in the
screen. If it appears, deactivate the key-lock setting. (See page
55.)

Cannot be
set

OUT1/OUT2
set value does
not go down.

Hysteresis is too
large.

Check the detected flow rate setting and the hysteresis, and
verify that the hysteresis width is not too large for the detected
flow. The detected flow rate has been set to 50% of the rated
value and the hysteresis set to 5% of the rated value before
shipment of the product from the factory.
When setting the hysteresis width to a narrower range, take
account of the occurrence of unstable display and outputs due to
pulsating flow.
