EDIT mode
The following settings can be made in EDIT mode:
–
Switching mode for OutA (air consumption [ConS] or flow rate [FLW] )
–
Switching function (threshold value or window comparator for OutA and OutB)
–
Switching points [SP] for OutA and OutB
–
Air consumption switching impulse [CI] only for OutA in switching mode [ConS]
–
Hysteresis [Hy] for OutA and OutB
–
Switching element function [no/nc] for OutA and OutB
–
Colour change of the display from blue to red for flow mode (for OutB)
In addition, the following settings can be made in the special menu:
–
Switching of the standard conditions via [Option] (OFF, 1, 2)
–
Physical units for flow rate [FLW] (l/h, scfm, l/min)
–
Analogue filter [AnA.F]
–
Digital filter [dIG.F]
–
Physical units for air consumption [ConS] (m3, scf, l)
–
Switching output [nPn/PnP]
–
Security code [Lock]

Starting EDIT Mode
WARNING
Manipulation of signal statuses may cause serious personal injury, depending
on the functioning of the machine/system.
• Note that if the switching status of the outputs is modified in EDIT mode, the
new status will be effective immediately.
The following settings can be selected with the control buttons (A/B pushbutton):
–
Switching output for which the characteristics is to be set
–
Special menu
1. Press the Edit button.
Ä
EDIT mode is active and [OutA] flashes. Lock flashes with active security
blocking.
2. Press the A/B pushbuttons until the chosen security code is set.
3. Press the Edit button.
Ä
EDIT mode is active and [OutA] flashes.
7.7.2
Setting the switching characteristics of the switching outputs
Both switching outputs (OutA/OutB) can be set for flow measurement. Switching
output OutA can alternatively be set for the cumulated air consumption meas-
urement. The cumulative air consumption measurement (OutA) and flow rate
measurement (OutB) can be combined.
7.7.2.1 Setting the switching function for flow measurement
The process for setting the switching outputs is fundamentally the same. Addi-
tionally, the switching mode [FLW] must be selected for Out A since Out A can
also be configured for air consumption measurement. The colour change for the
display can also be set for OutB. In the following, the process is described using
the switching output OutA.

SFAB is in RUN mode.
14. Check whether the SFAB switches as desired with a test run (vary the flow
rate).

8. Check whether the SFAB switches as desired with a test run (flow rate).
7.7.3
Setting the colour change (only for OutB)
In order to detect the system status over longer distances, a colour change can be
set at the OutB output. If the set switching threshold is exceeded or not reached,
the colour of the display changes.
The following settings can be selected:
–
r.ON
–
Display is red when the switching output is High (1).
–
Display is blue if the switching output is Low (0).
–
r.OFF
–
Display is red when the switching output is Low (0).
–
Display is blue if the switching output is High (1).
