FIMER R SERIES
Listed below are the requirements for initial action on a failed inverter. Before proceeding with any operation: A) Verify that the model is correct; B) Carefully follow all instructions provided in the manufacturer’s operation and maintenance manual; C) Ensure that the intervention is carried out by trained personnel; D) Since this is a photovoltaic inverter with a DC input that is always live, strictly observe all applicable safety regulations.

Possibile soluzione
|
|---|---|---|---|
|
11 |
Voltage near the limit |
Loose tension is close to the set limit |
Check the values of the three phases: if they are close to the limit even when the inverter is off you need to check the transformer, if the phase values are close to the limit only when the inverter is running contact STI REPAIR service |
|
12 |
Degraded service |
A module failed to activate after at least three attempts. The module was deactivated |
If the problem persists, contact STI REPAIR service. |
|
13 |
Loss of DC insulation |
An inverter insulation loss has been detected. The fuse of the "grounding KIT" has blown due to a current beyond its limit |
Check the fuse of the grounding kit and replace it if it is blown. In case the new fuse blows immediately after the new replacement, contact STI REPAIR service department |
|
14 |

|
15 |
Modxxx Alim KO 24V |
Lack of 24 V DC from the module's DC stack |
Check the status of VAUX auxiliary switches (they must be closed) or the presence of the auxiliary line fed by the auxiliary transformer ***. |
|
16 |

Problems with the calibration of the module motherboard |
Contact STI REPAIR Service |
|
18 |
Modxxx No configuration |
No module configuration |
Contact STI REPAIR Service |
|
19 |
Eeprom Modxxx Error |
Problems with motherboard eprom |
Contact STI REPAIR Service |

20 |
Modxxx Overcurrent R |
Overcurrent in the first phase |
Check the circuit breaker connections of the module in error but only to inform the STI REPAIR service of its main switchboard. If possible that the overcurrent was experienced by the inverter for a temporary spike. If the problem recurs, notify the STI REPAIR service. |
|
21 |
Modxxx Overcurrent S |
Overcurrent in the second phase |
Check the circuit breaker connections of the module in error but only to inform the STI REPAIR service of its main switchboard. If possible that the overcurrent was experienced by the inverter for a temporary spike. If the problem recurs, notify the STI REPAIR service. |
|
22 |
Modxxx Overcurrent T |
Overcurrent in the third phase |
Check the circuit breaker connections of the module in error but only to inform the STI REPAIR service of its main switchboard. If possible that the overcurrent was experienced by the inverter for a temporary spike. If the problem recurs, notify the STI REPAIR service. |
|
23 |
Modxxx Overtemperature Mag1 |
Magnet (transformer) overtemperature |
Check the connection labeled "J17" on the unit control board (not present on the R15015TL inverter or otherwise in transformerless inverters). If the cable coming from the temperature sensor (the red one) that is plugged into the magnet is well connected, the problem could be overtemperature. Contact STI REPAIR service. |
|
24 |
Modxxx Overtemperature Mag2 |
Magnet overtemperature (inductance) |
Check the connection marked "J16" on the unit control board. If the The cable coming from the temperature sensor (the gray one) that is plugged into the magnetic inductor is well connected, the problem may be overtemperature. Contact STI REPAIR service. |
|
25 |
Modxxx RS Overvoltage |
Measured overvoltage between phases RS |
Check the value of the three phases: it should be around 550Vac. In case the phase values are ok, check the circuit breaker connections of the module in error but only to inform the STI REPAIR service about its general status. If everything is okay, restart the inverter for a second try, you may have experienced overvoltage from the inverter for a temporary surge. If the problem recurs, notify the STI REPAIR service. |
|
26 |
Modxxx Overvoltage ST |
Measured overvoltage between phases ST |
Check the value of the three phases: it should be around 550Vac. In case the phase values are ok, check the circuit breaker connections of the module in error but only to inform the STI REPAIR service about its general status. If everything is okay, restart the inverter for a second try, you may have experienced overvoltage from the inverter for a temporary surge. If the problem recurs, notify the STI REPAIR service. |
|
27 |
Modxxx Overvoltage TR |
Measured overvoltage between phases TR |
Check the value of the three phases: it should be around 550Vac. In case the phase values are ok, check the circuit breaker connections of the module in error but only to inform the STI REPAIR service about its general status. If everything is okay, restart the inverter for a second try, you may have experienced overvoltage from the inverter for a temporary surge. If the problem recurs, notify the STI REPAIR service. |
|
28 |
Modxxx UDC Overvoltage |
Overvoltage in DC voltage |
Check the VDC voltage value and if it is within the normal range (around 850-1320 Vdc) try restarting the inverter. In case the alarm occurs again, contact STI REPAIR service. |
|
29 |
Modxxx Shutdown KO |
Problems in driving the module's DC stack |
Check the presence of the auxiliary line and/or DC pack operation of the module: if both are ok contact STI REPAIR service |
|
30 |
Modxxx Ramp KO |
Module fails to finish the startup procedure: problem reading values |
Check all wire connections on the electronic boards of the modules. If problems persist after a reboot, contact STI REPAIR Service. |
|
31 |
