11.2 Function

The cycle time extension extends the cycle time of the electrical actuator. For this, the
actuator moves to the end positions in a clocked manner (OPEN or CLOSED) or to the
middle position (if accessory for middle positioning is present).
Switch position for 90° cycle, see Table. Cycle time without mounted switches = 5 s for
90 ° on EA21; 15 s for 90 ° on EA31; 25 s for 90 ° on EA42.

Switch positions 8 – 9 have the function of switch position 7. The cycle time extension
is also active in case of a malfunction or in combination with the reset unit accessory.
I.e. in case of a power failure, the end positions are approached with a delay.
