There is a caution statement that "OUT pressure will be retained temporarily when the product is in a controlled state even if the power is cut off". What does it mean?

When the power is switched off while the product is in a controlled state, both supply and exhaust solenoid valves will close.
Then, as the pressure in the pilot chamber will be retained, the ITV OUT pressure will stay around the set pressure.
However, since it is just temporal state (due to air leakages that might happen), SMC cannot guarantee the product performance.
