SDE5-...
6.2 Setting the switching pressure on the
SDE5-...-C1/C2/C3/O1/O2/O3-... :
1. Pressurize the SDE5-... with the a teach
pressure (e.g. TP1). The sequence of the
teach pressures is not important.
2. Press the EDIT button 1 until the LED
starts to flash. When the button is re-
leased, the SDE5-... saves the first teach
pressure. The LED then continues to flash.
3. Pressurize the SDE5-... with the other teach pressure (e.g. TP2).
4. Press the EDIT button 1 until the LED stops flashing.
When the button is released, the SDE5-... saves the second value. The relation-
ship between teach pressure, switching pressure and hysteresis is shown in
the following table. For mode 1 the switching pressure is formed from the aver-
age value of both teach pressures SP = 1/2 (TP1 + TP2).
Carry out a test run with various pressures to ascertain whether the SDE5-...
S
switches as desired.
