Function
After the auxiliary supply (A1-A2) has been switched on, the stepping relay switches
its two change-over contacts into the ON position with the rising edge of the
energizing quantity (B1-A2).
The change-over contacts are returned into the OFF position with the next rising edge
of the energizing quantity. This occurs alternately when the energizing quantity is
switched on. When the auxiliary supply is switched off the change-over contacts
switch into the OFF position. LEDs show the state of the excitation input and the
position of the contacts.

Notes
The device is designed for multi-voltage. Phase L1 or L+ must be connected to
terminal A1; neutral conductor N or M must be connected to terminal A2.
