To check the AC protection branch, you should see continuity between the ends of the monitoring circuit: Q1 11 and
Q2 14. Next you should check that power is reaching the electronics block from X.3.4. To do this, check that there is
continuity between terminals X3.4 and J19.6.
If there is continuity between terminals X7.1 and X3.3 of the AC branch arrester, it is running properly.
To locate the position of the terminals within the intake board, see explanatory drawing titled “Intake
board” .
9.4.4. Reason for contactor shutdown
Code Alarm Reason for shutdown Description
0100H AC protections Reason for contactor shutdown The state of the contactor is not correct for the
current inverter status.
The “contactor” reason for shutdown is associated to alarm 0100H. This reason for shutdown requires checking the
following points:
• Contactor coil wiring. There should be continuity between terminals X8.2 and X2.3, between X2.4 and
K1.A1 and between X8.5 and K1.A2. Proceed to check that the electronics block is powered. To do this, check
continuity in the following points:
• X2.3 – J16.1
• X2.4 – J16.3
• Signalling status. Resistance between terminals X7.1 and X3.2 should be measured as approximately 4.5
kΩ.
9.4.5. DC circuit protections
Code Alarm Reason for shutdown Description
0200H DC protections DC protections DC arresters.
In the event of a 0200H alarm, check the status of the DC arresters To check for proper status observe the following:
• Continuity between terminals X7.2 and X3.1.
• Continuity between X3.1 and J19.1.
9.4.6. Insulation fault
Alarm 0400h is related to an insulation fault and can be one of two types:
• External to the unit.
• Internal to the unit.
