Voltage And/Or Frequency Out Of Range - Ingecon Sun 250 M220 Indoor Installation Manual

Installation manual
IMPORTAnT
Only in the event of an insulation fault triggered by alarm 0400H will the Ac power be switched off
and the Dc power be left.
3. Open the unit and find the section in this guide that deals with the alarm or reason for shutdown recorded
in the first step.
4. use a category III, 1000 V
proceed to carry out the checks listed here.
5. If unable to solve the problem using this guide, take note of the unit's serial number and contact technical
service.
Below is a list of possible reasons for shutdown, their associated alarms and troubleshooting guidelines. If more than
one alarm takes place, the alarm on the display will be the sum of all active alarms.
e.g.:

9.4.1. Voltage and/or frequency out of range

One reason for shutdown associated with out-of-range voltage and/or frequency features the alarm codes listed below:
code Alarm
0001H Grid frequency
0002H Voltage
0003H Grid frequency + voltage
In the event of a 0001H and/or 0002H alarm, you must check the status of the Q4 thermomagnetic protection and
all the wiring associated with it. This check requires verifying the correct status of the following areas of the unit:
1. check that Q4 is switched On in each of the power modules (Q4.1, Q4.2, etc.).
2. check the proper status of fuses F16, F17, F18, F26, F27, F28, F36, F37, F38, F46, F47, F48.
3. Status of RVac1, RVac2, RVac3 and RVac4 arresters located in the Ac output module of the units. To verify
its correct status, verify that they are properly attached to their base and that the status window of none of them
is red.
4. Once the arresters have been checked, check that the QAc1, QAc2, QAc3 and QAc4 thermomagnetic
circuit breakers located in the Ac module at the inverter output are switched On.
note: The Ac module must be closed to switch On the thermomagnetic circuit breakers listed above.
In the event that Q4s in all power modules are switched On and none of the fuses are blown, the next step will be
to ensure that both the Ac voltage intake and the electronics block are powered. The procedure requires performing
the following checks:
1. check that the Q4 thermomagnetic circuit breakers are not damaged. With Q4 switched On, measure the
flow resistance offered by Q4 for each phase. The resistance for each of the phases must be within the 60 to 70
Ohm range. The following figure details the test to be performed.
