Programming The Time-Out Before Switching - bürkert 8041 Bedienungsanleitung

3.6.4 Programming the time-out before switching

If need be the switching threshold of the relay output can
be timed-out (from 0 up to 100 seconds), i.e. the switch ing
only occurs when either threshold is ex ceed ed for a dura-
tion higher than the time-out.
A time-out set to 0 means that the switching occurs im-
mediately.
To set the time-out, do as follows:
- The green led flashes once and the red led is off
(Readout mode). If not, refer to § 3.1
- Press the push-button four times briefly: the green led
flashes five times and the bargraph shows the present
time-out (in seconds).
- Press the push-button and hold: After 2 seconds the
red led lights up (Configuration mode) and led N°1 of
the bargraph flashes 9 times (1 flash = 1 s) then it
lights up;
The next leds then light up one after the other;
Release the push-button when the desired number of
leds is lit (1 led lit = 10 s).
Press and hold the push-button again: After 2 seconds
the next led flashes (1 flash = 1 s).
Release the push-button when the desired flashing is
reached.
- If necessary, press and hold the push-button again to
change the displayed value.
- Press the push-button briefly to validate the value
visualized by the bargraph and automatically return to the
flow velocity Readout mode or wait for 10 s to return to
the flow velocity Readout mode without validating the
displayed value.
