Output terminal
Output signals of Safety function are redundant outputs of
terminal group -1 and terminal group -2.
When the Safety function is inactivated, voltage is applied
to each output and currents flow on each safety path.
When the Safety function is activated, voltage is removed
from each output and currents do not flow on each safety
path.
When the monitoring and completed signals are activated,
voltage is applied to each output and currents flow on each
path. When the monitoring and completed signals are
inactivated, voltage is removed from each output and
currents do not flow on each path.
The voltage source for output signals of safety function is
an externally prepared DC24V power supply. The external
power supply must be SELV or PELV DC24V power supply.
Please connect between
corresponding common for checking the path if the output
terminal is not used.
