CONNECTION DIAGRAM
A supply voltage must be applied via emergency stop button to terminals A1
and A2. Power LED illuminates if the emergency stop is closed. To start the
unit terminals Y2 and Y1 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, contact 41-42 is opened. The LEDs channel 1 and
channel 2 illuminate. In series to this start button an external contactor can
be monitored.
