Pressure roller accumulator extended?

Pressure roller accumulator extended?

• A. 1,100 psi
• B. 1,200 Psi plus 20 or minus 0 with tape extended
• C. 1,300-1,400 psi with tape retracted
• D. 1,500 psi

Answer: (B)

When the pressure roller is in the extended position, the hydraulic accumulator has a defined target pressure that must be met with only a small allowable increase. This ensures there is enough force to keep the roller extended while the tape is out, without letting the pressure drift too high. The correct option reflects that exact idea: it states the nominal extended-state pressure and allows a small positive tolerance, aligning with how the system is calibrated for extension. The other possibilities describe either a pressure that’s too low to reliably maintain extension or a value that’s outside the permitted range, and one describes the retracted-state condition instead. In short, extended operation relies on a specific pressure band with a slight upward tolerance, which is why that choice is the best fit.
