7.2.3 IPS Check (for Italy CEI0-21 Grid Code Only)

Function
The Italy CEI0-21 grid code requires an IPS check for the SUN2000. During the
self-check, the SUN2000 checks the protection threshold and protection time of
the maximum voltage over 10 min (59.S1), maximum overvoltage (59.S2),
minimum undervoltage (27.S1), minimum undervoltage (27.S2), maximum
overfrequency (81.S1), maximum overfrequency (81.S2), minimum
underfrequency (81.S), and minimum underfrequency (81.S2).
Procedure
Step 1 On the home screen, choose Maintenance > IPS test to access the IPS test screen.
Step 2 Tap Start to start an IPS test. The SUN2000 detects maximum voltage over 10 min
(59.S1), maximum overvoltage (59.S2), minimum undervoltage (27.S1), minimum
undervoltage (27.S2), maximum overfrequency (81.S1), maximum overfrequency
(81.S2), and minimum underfrequency (81.S1), and minimum underfrequency
(81.S2).
