Operating modes 8 – 9 monitored zone access
Working principle:
1. As long as the remote control is in the
charger station (control contact S31-S32
is closed), the machine is protected by the
hardwired e-stop on S11 to S14 and the
light curtain or safety gate on S21 to S24.
This state is indicated by the switched off
white LED run2 and inactive output 58.
2. Before the operator enters the protected
area, he takes the remote control from the
charger. The control contact S 31-S32
opens, the white LED run2 and the out
put 58 flash fast. This indicates that the
remote e-stop button has to be released
and the remote control has to be acknow-
ledged by pressing the green start button
within the selected time. If not, the safety
relays will disconnect.
3. If the remote control is acknowledged
within the required time the white LED
run2 and the output 58 turn to be con-
tinnuously on.
4. Before entering the protected area the
operator must activate and de-activate the
outside entry release button (S33-S34)
and the green start button on the remote
control at the same time. From this mo-
ment the light barrier or safety gate func-
tion is disabled for the adjusted time. Du-
ring this period the white LED run2 and
the output 58 flash slowly and symmetric
to indicate the disabled protection.
