ASSEMBLY INSTRUCTIONS
The
BSR
safety block system is an automatism
that, when coupled to the J4C multi voltage
electric actuators, lets the valve situate in a
preferable position NC or NO, when there is a
power supply failure. Inside of the housing there
are a
BSR
print circuit board and a battery pack,
which is kept in continuous charge.
In case of the valve is not in the preferable
position and there is a power supply cut, the
BSR
system returns the valve back to the preferable
position by means of the batteries tension,
operating as a “single acting” actuator.
