9.4.3. AC circuit protection

Code Alarm
0100H AC Protection
In the event of a Motivo_Paro_Prot_AC reason for shutdown, check the status and monitoring of the AC circuit protec-
tions of the module in question.
To check the status of the protections, perform an in-depth check of section "6. Commissioning" in this document.
If the AC circuit protection status is correct, proceed to verify their monitoring. To do this, you will need to check the
monitoring branches:
AC PROTECTIONS
Consists of thermomagnetic switches IQ3, IQ4, IQ5 and IQ1 in units with a transformer and IQ2, IQ4, IQ5 and IQAC
in TL units.
AC ARRESTER.
Consists of IRV4–5.
To test the AC supply branch there should be continuity between IQ3 13 and IQ5 14 in units with a transformer and
between IQ2 13 and IQ5 14 in TL units. Then you should check that power is reaching the electronics block from
X.1.5. To do this, check that there is continuity between terminals X1.5 and J19.6.
If there is continuity between terminals X7.7 and X1.4 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" in section 8.4.1

9.4.4. Reason for contactor shutdown

Code Alarm
0100H AC protections
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 X3.1 and X3.2. Proceed to check that
the electronic block is powered. To do this, check continuity in the following points:
• X3.1 – J16.1
• X3.2 – J16.2
• Check continuity first between X8.1 and X3.1 and then between X3.1 and X8.2.
• Signalling status. Resistance between terminals X7.5 and X1.3 should be approximately 5.5 kΩ.

9.4.5. DC circuit protections

Code Alarm
0200H DC protections
In the event of a "0200H" alarm, check the status of the DC fuse branch. To check for proper status observe the
following:
• Continuity between terminals X7.7 and X1.1.
• Continuity between X1.1 and J19.1.
