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.
VERY IMPORTANT:
PLEASE, FOLLOW THESE INSTRUCTIONS STEP BY STEP.IF THE CONNECTOR OF THE BATTERY PACK
IS PLUGED TO THE "BSR" PCB, BEFORE ARRIVING TO POINT 7, THE PCB COULD BE DAMAGED.
