Setting of the display
7 options can be selected:
d1 = update of the measured value every 50 ms
d2 = update of the measured value every 200 ms
d3 = update of the measured value every 600 ms
The update interval only refers to the display. It has no effect on
the outputs.
rd1, rd2, rd3, = display as d1, d2, d3; rotated 180°
OFF = In the Run mode the display of the measured value is
deactivated.
If one of the buttons is pressed, the current measured value is
displayed for 15 s. If the Mode/Enter button is pressed once again,
the Display mode is activated. The LEDs remain active even if the
display is deactivated.
Setting at the factory: dis = d3.
Display unit
The measured value and the values for TSPx, SPx, TOLx, HYSx can
be displayed in the following units:
mbAr (mbar), PSI, kPA (kPa), IH2O (= inH
Select the display unit before setting the the values for TSPx,
SPx, TOLx, HYSx. This avoids rounding errors generated internally
during the conversion of the units and enables exact setting of
the values. Setting at the factory: Uni = mbAr.
The switch point can be adapted to changes in the surface via the
menu items TOL1/TOL2. The basic settings of the unit (bridge adjust-
ment and values of the switch point) are not changed by this.
Please consider:
SP = SP1/2 + TOL1/2
Real (TOL1/2)
Example:
- SPx = -20 mbar
- TOLx = 30 mbar
→
The unit switches at 10 mbar.
The real switch point should be as near as possible to the value "0"
(see page 27).
If the output is to be safely reset (changing from "OK signal" to "BAD
signal") in the event of a failure of the supply pressure (P-SUP = 0):
• Turn the setting dial until just below the value "-20" in the
display, or
• set the switch point (SPx) to the value -20 or smaller.
