During emission halt, the control output (OSSD 1 / 2) becomes OFF state.
By using this function, malfunction due to extraneous noise or abnormality in the control output
(OSSD 1 / 2) and the auxiliary output can be determined even from the equipment side.
Normal operation is restored when the emission halt input / reset input is connected to 0V or +V

sion under open status and performs emission halt under short-circuit status.
Do not use the emission halt function for the purpose of stopping the machine in
which the
SF4B<V2>
series is installed. Failure to do so could result in death or
serious injury.
3-4 Interference Prevention Function
It is possible to construct the system to prevent malfunction due to
interference of the light between
SF4B<V2>
series devices.
The interference prevention system can construct max. three sets
of series and parallel mixed connection.
The max. number of the beam channels in series and parallel
mixed connection is 192.
