◆ Troubleshooting
If the Sleep Boost pressure does not achieve 110 psi before shutting down:
• Ensure that the pump system in use can produce this Sleep Boost psi level.
• Extend the Sleep Boost Time (P2-22) in increments of 5 s. With longer acceleration rates, the Sleep Boost Time may require
adjustment.
• The drive will stop the Sleep Boost Cycle when either the boost pressure of 110 psi is achieved and/or when the Sleep Boost Time has
expired.
