Functional tests
A ) Use the ITK to check if the RSD is working as desired. When the RSD is
engaged (turned to OFF position) , all the relays except the MID will be
open. Only the MID relay will be closed. Hence effectively isolating the
home from the PV, battery and generator.
B ) In order to check if the RSD is functioning as required, open the ITK
and manoeuvre to the Enpower page.
C ) Turn the RSD rotary handle to OFF position.
D ) In the ITK’s Enpower page, click on “View Live details”.
E ) In the view live details page, the relay status should be as shown in
Figure 6 below. The MID relay should be closed and all other relays
should be in open position.
F ) When RSD handle is shifted to ON position, the Enpower goes back
into functioning normally as it was.
