INSTALLATION (continued)

Set up sensor

6

For IQ controllers link input channel for voltage V and set up the sensor type scaling; the
recommended method of setting the sensor type scaling is to use SET.
For all IQ2 series controllers with firmware of version 2.1 or greater, or IQ3 series controllers,
one of the following SET Unique Sensor References should be used:

CT V 200A (for CTX/200)
CT V 500A (for CTX/500)

Alternatively use sensor scaling mode 5, characterise, and enter the scaling manually as defined
in the table shown.

For all other IQ controllers see the Sensor Scaling Reference Card, TB100521A.
