TEACH mode
Enables teaching of switching points within the maximum setting range
(see Technical specifications).
S
Before teaching make sure that the desired switching function (window or
threshold comparator) and the desired hysteresis are set in the EDIT mode
(see under EDIT mode).
Threshold comparator setting Window comparator setting
The (taught) switching point is derived
from the average value of both teaching
points.
Calculation formula: SP = 1/2 (TP1 + TP2)
If both teaching points are the same, the
following applies: SP = TP1 = TP2. The taught switching window is derived
from: SP
min
= smaller teaching point
(TP1 or TP2); SP
max
= greater teaching
point (TP1 or TP2).

For teaching the switching variables:
1. Apply first measuring pressure (relative press. p1 / differential press. p1p2).
2. In order to activate the TEACH mode and to accept the measured value as the
first teaching point (TP1), first press the button for the desired switching out
put (Out A/B), then press the EDIT button while holding down the switching
output button.
3. Only with active security blocking [lock] flashes:
S
Press the UP/DOWN button until the desired security code is set.
S
Press the EDIT button.
The switching output symbol [A] or [B] will flash.
4. Apply second measuring pressure (relative press. p1 / differential press. p1p2).
5. In order to accept the measured value as the second teaching point (TP2), first
press the button selected under 2., then press the EDIT button while holding
down the switching output button. The new switching point (SP) or the new
switching points (SP
min
and SP
max
) will then become valid. The SDE1−... is then
in the RUN mode again.
