Electrical properties

The FF CP card does not sit in the main control path for the actuator and does not affect the actuator
control integrity.
Internally stored programs control the processors on the module. The Network Interface processor
software may be updated by connecting a suitable test cable and loading the new code directly, but
this cannot be done in the field The FF system allows all settings for the data highway and module
communication functions to be held in non-volatile memory on the Network Interface Card.
The FF data highway connection is fully isolated from the actuator electronics.
2.3

Operation and storage

The Module is designed to be stored in the actuator and operated within the same environment as the
actuator.
The constraints are:

Operating temperature: -40

Storage temperature:

Relative Humidity:
Refer to actuator manuals for range applicable for the particular actuator type.
