DIP Switches
NOTE:
- The black position indicates the active switch setting.
- For Siemens FHC/LRC pulsed control signal applications, see Section F2.
- On initial power-up, and after a power-fail event, the GNP actuators require up to 90 seconds to fully charge their capacitors. During this time the actuator will respond to positioning commands, but will not power-fail until the capacitors are fully charged.
NOTE: An improperly tuned loop will cause excessive repositioning that will shorten the life of the actuator.
