CONNECTION DIAGRAM
A supply voltage must be applied via emergency stop 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 are
closed. The LEDs channel 1 and channel 2 illuminate. In series to this start
button an external contactor can be controlled.
