CONNECTION DIAGRAM
A supply voltage must be applied at terminals A1 and A2. The power LED
lights. Terminals S11, S12, S21 and S22 have to be wired up as shown in
the application examples. To start the unit, follow the examples
described in the start applications section. In series to the start-button an
external contactor can be controlled (see application example). After
activation the contacts 13-14, 23-24 and 33-34 are closed, contact 41-42 is
opened. The LEDs channel 1 and channel 2 are lit.
