Which condition would be considered a typical interlock safety signal in a pressurized system?

• A. Oil pressure is at a safe range
• B. Temperature inside the cabinet
• C. Battery level on the controller
• D. Time of day

Answer: (A)

Interlocks are safety checks that stop a dangerous action until a critical condition is met. In a pressurized system, maintaining proper oil pressure is essential for lubrication and seal integrity; when oil pressure is in the safe range, the components are protected and the system can operate without risk of sudden failure. That makes oil pressure a natural interlock signal: if oil pressure falls out of range, the interlock trips and prevents energizing or continuing operation. Temperature inside the cabinet could indicate overheating, but it doesn't directly verify safe pressurization; battery level concerns power availability rather than the pressure state; time of day is unrelated to the safety state of the system.
