The ATS22 does not display current on LCr2, do I have a faulty unit?

This is normal operation because the ATS22.../Q has CT's installed in the U and W phases only, no sensor installed in the V phase.
 
On the ATS22..S6 ( dedicated mainly for US market) three CT's are used and LcR2 indicates a value. The three sensors are used in US market because the ground fault detection is mandatory.
