CONNECTION DIAGRAM
A supply voltage must be applied to terminals A1 and A2. Power LED
illuminates and 24 V DC is available at terminal S11. Terminals S12 and S22
must be connected according to the application example selected to meet the
application requirements. To start the unit terminals S33 and S34 must be
bridged with a normally open contact. The unit works if you close this contact.
At this time the contacts 13-14 and 23-24 are closed. The LEDs channel 1 and
channel 2 illuminate. In series to this start button an external contactor can be
controlled
