4 MAINTAINING THE HFG2.0
Under normal operation, the HFG2.0 requires no formal maintenance
program.
Regularly scheduled inspections should be performed to check for:
• any damage to wire insulation on integral 17-wire signal harness
• any damage to wire insulation on integral 4-wire power harness
• actuator-to-valve alignment (or actuator-to-load alignment)
• any damage to housing or mounting hardware
• any damage to power and signal harnesses
• parts that are worn, loose, or shifted due to shock, vibration, etc.
4.1 Refurbishment
PECC recommends that the HFG2.0 be shipped back to the factory for
refurbishment when the user’s system is shut down for overhaul (typically
after approximately 30,000 hours of operation.) Contact PECC for details
about refurbishment.
