XX62 | Matrix Temperature | S | This fault indicates that the PV100S | • Fuses F15 or F16 blown | |
|
|
| has detected that the temperature of | • | External cooling fan |
|
|
| the IGBT matrix aluminum heatsink |
| inoperable |
|
|
| has exceeded the maximum allowed | • Air flow on heat sink | |
|
|
| value of 95 °C. |
| impeded due to |
|
|
|
|
| accumulation of debris |
|
|
|
| • | Operation above rated |
|
|
|
|
| ambient temperature for |
|
|
|
|
| an extended period of |
|
|
|
|
| time |
|
|
|
|
| |
0070 | Interlock Activated | H | This fault indicates that the PV100S | • Door is open and | |
|
|
| has detected that the door of the Main |
| interlock switch is |
|
|
| Inverter enclosure is open and the |
| active |
|
|
| door interlock switch is in the active | • | Interlock switch is |
|
|
| position. This fault is primarily for |
| inoperable |
|
|
| personnel safety. Opening the door of | • P2 or P3 on CCU2 is | |
|
|
| the Main Inverter enclosure while the |
| loose or disconnected |
|
|
| PV100S is processing power will | • | CCU2 |
|
|
| cause an immediate orderly shutdown |
| Supply is defective |
|
|
| of the system. |
|
|
|
|
|
|
| |
0071 | PV Switch Open | H | This fault indicates that the PV100S | • DC disconnect switch is | |
|
|
| has detected that the DC disconnect |
| open and auxiliary |
|
|
| switch (S2) is open and the auxiliary |
| switch is active |
|
|
| switch is in the active position. This | • | Auxiliary switch is |
|
|
| fault is primarily for personnel safety. |
| inoperable |
|
|
| Opening the DC disconnect switch | • P2 or P3 on CCU2 is | |
|
|
| while the PV100S is processing |
| loose or disconnected |
|
|
| power will cause an immediate | • CCU2 | |
|
|
| orderly shutdown of the system. |
| Supply is defective |
|
|
|
|
|
|
0074 | Fused PV Contactor | S | This fault indicates that the PV100S | • | K2 is inoperable |
|
|
| has detected that upon system | • | SSR2 is inoperable |
|
|
| shutdown, the DC bus voltage has |
|
|
|
|
| remained within 5% of the DC input |
|
|
|
|
| voltage for more than 10 seconds. |
|
|
|
|
| This condition is indicative of a fused |
|
|
|
|
| PV contactor (K2). |
