Installing the Feedback Module (Iy Module)
Feedback Module (ly Module)
Function
The optional Iy module indicates the current actuator position as a
dual line signal with Iy = 4 to 20 mA. The Iy module is potentially
isolated from the standard controller. Due to the dynamic control,
this module can report the arising operational faults automatically.
Device features
The Iy module is:
• Single channel
• Potentially isolated from the standard controller.
Note: The current actuator position is indicated only after a suc-
cessful initialization of the positioner. [Refer to the “Calibration
and Commissioning” section]
Proceed as follows to install the optional Iy module:
1. Perform Step A to remove the module cover
2. Slide the Iy module up to the end stop in the lower stack of the
module rack.
3. Connect the module to the motherboard. For this purpose, use
the 6-pole flat ribbon cable provided.
4. Refer to Figure 8 and Figure 9 to connect the Iy module in
standard and intrinsically safe applications.
