Installation Guidelines
-
Finger-Tight Only: Connect the cable to the probe and Proximitor sensor by hand until a click is felt or heard. Do not use pliers or wrenches; maximum torque is 0.565 N-m (5 in-lb).
-
Bend Radius: Maintain a minimum bend radius of 25.4 mm (1.0 inch) to prevent damage to the internal coaxial structure.
-
Connector Protection: Use connector protectors for all connections to prevent moisture or oil ingress. Silicone tape may be used in non-oil environments, but is not recommended for applications exposed to turbine oil.
-
Handling: Ensure the system is powered down before disconnecting or connecting components to prevent signal noise or potential damage.
FAQ
