Note
Different cable glands
A blue and a gray cable gland are provided to distinguish between explosion
-proof and not
explosion
-proof devices.
•
Use the blue cable gland for explosion-proof devices in "intrinsically safe" protection type.
Use the gray cable gland for all other designs.
Function
You will require the EMC filter module if you use an external position sensor on the
positioner, e.g. a potentiometer or a non-contacting position sensor. The EMC filter module
forms the interface between external position sensors and the basic electronics of the
positioner. This module protects the positioner from electromagnetic effects.
