What are the two LPAC 2 operating modes?

• A. Automatic
• B. Manual
• C. Automatic & Manual
• D. Off

Answer: (C)

LPAC 2 has two control modes: automatic and manual. In automatic mode, the LPAC 2 is governed by the control system, using sensors and preset logic to maintain the desired pressure or flow without operator intervention. This is how it runs during normal operations, responding to load demands and system conditions automatically. In manual mode, an operator can override the automatic control to directly set parameters such as speed or valve positions for testing, maintenance, or troubleshooting when automatic logic needs to be bypassed. The two modes together cover both routine operation and hands-on control, which is why the correct answer lists both modes. The option that implies only one mode isn’t capturing the alternative method of operation, and “Off” is simply a shutdown state rather than an operating mode.
