If 3 sec. mode is selected, the self adju-
stment of angel of rotation must be started
and operation mode of max. 10% ED
must be guaranteed.
Never operate actuator in the 3 sec mode
without an outside load of min. 3 Nm.
Engaging 1 wire On/Off controlls in the
3 sec. modus with spring return, the ac
tuator can only be operated with 1 On/Off
function per minute otherwise electronics
will be liable to overheating.
