Switch 1 (only for 24 V): Valve blocking protection - If system conditions allow, valve blocking
protection can be activated during commissioning. Blocking protection prevents the cone from
sticking when the valve has not been in operation for a longer period of time, e.g. when the cold
water circulation has not yet been started. When blocking protection is activated, the valve cone
is lifted for a few seconds if there has been no lifting movement within 21 days.
Switch 2 (only for 24 V): Setting the control range of the continuous control signal 0..10 V DC or
2..10 V DC (see table on page 24).
Switch 3 (only for 24 V): Setting of servo drive direction and position feedback for control
voltage 10 V DC „Valve open"
Switch 6: Reinitialisation - If the valve is reinstalled, it must be taught in again through reinitiali-
sation. This is done by changing the position of switch 6 from „OFF" to „ON" or from „ON" to
„OFF". During initialisation, the LED under the access cover flashes and the stroke scale moves.
After a full positioning run (9 mm), reinitialisation is completed by resetting switch 6.
