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.
