This vent plug is a safety device that must be handled as such. Do not cover the
vent plug. When fitting the control top note that the installation position of the vent
plug (E2) must never be pointing vertically upwards.

Reset function
In order to change saved positions (e.g. after seal replacement), the saved
positions have to be deleted (reset). The reset button must be pressed for 3 – 7
sec. for this.
•
Reset function is only possible live.
•
After the button has been pressed for 3 seconds, the reset is initiated and the
LED goes off.
•
The actual reset is carried out as soon as the button is released. This must
take place within 4-7 seconds of pressing.
•
If the reset switch is not released after 7 seconds, no reset takes place and
the previously learnt actuated and non-actuated positions are retained and/or
normal mode is resumed. It is irrelevant how long the reset switch is pressed.
•
The learning process starts automatically 1-2 seconds after reset
®
Red steady light for 1-2 seconds. The LED flashes red until the signal of the
non-actuated position is recorded.
•
Learning process completed
®
Steady light green (with DIP1=0) with additional flashing of the yellow LED
(green 750 ms/ yellow 250 ms) or yellow steady light (with DIP1=1) with
additional flashing of the green LED (yellow 750 ms/ green 250 ms).
Position of the non-actuated position within the tolerance is signalled with the
LED as steady light in accordance with tab. 1 and 2, or as described before! As
long as the actuated position has not been saved, the position of the non-
actuated position is signalled within the tolerance with the LED as steady light
and additional flashing of the LEDs in accordance with Tab. 1 and 2, or as
described before.
Activate solenoid valve Y1 for main stroke (activate by operating the manual
override device or by actuation of the higher-order control). Learning is completed
when actuated and non-actuated position have been detected and learnt. If
voltage is only switched off with one learnt position, the position already learnt is
discarded. If the actuated and non-actuated positions have been detected and
learnt, the saved positions are retained when the device is switched back on
again following disconnection of the voltage supply. If the positions of the non-
actuated and actuated position are saved, the detection of every position outside
the position tolerance is signalled by the yellow or green LED flashing, see
Deactivate the solenoid valve.
Observe the general instructions regarding ESD protection.
