Automatic start/monitored start modes of operation
Two modes of operation are possible:
–
Automatic start (automatic reset)
The automatic start (automatic reset) mode of operation is preset with a bridge from terminal 5 to
terminal 6 in the multi-pin plug socket NECA (delivery status).
–
Monitored start (monitored reset)
The monitored start (monitored reset) mode of operation should be seen as a subordinate start
from the perspective of the complete system. The enable signal from the safety relay or the con-
troller always has priority.
In both modes of operation, the product can be electrically triggered using either static or dynamic
enable signals (EN1/EN2), depending on the multi-pin plug socket NECA used.
The impulse generated by the start button must be within a time-frame of 0.1 s and 2 s.
If the start button is held down for too long or is locked down, the system identifies a cross circuit and
the product is placed in fault mode.
The start signal for S34 must not be generated until 1 s after the enable signals EN1/EN2 are gener-
ated.
If the start signal is generated before or simultaneously with the enable signals, it will not be recog-
nised and must be generated again.
