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, 23-24 and 33-34 are closed.
The LEDs channel 1 and channel 2 illuminate. In series to this start button
an external contactor can be controlled.
