3.1.4. Fault codes
The following table lists the fault codes and gives a brief description of each fault. A more de-
tailed description of the fault and advice on how to locate the faulty component will be given
afterwards.
Fault code Fault type Cause
10 System confi guration fault Number of sensors changed
11 Damaged I/O unit Faulty I/O unit in the system
12 Too long BI/O bus activation Faulty arc sensor or too low setting in the
current I/O unit
13 Communication fault Faulty communication channel
14 BI/O channel fault Communication between two master units
interrupted
15 Quenching device fault Communication to quenching
device is interrupted

System confi guration fault (fault code 10)
Figure: The system indicates a confi guration fault in the I/O unit whose address is 01
This fault code indicates a change in system confi guration.
Potential causes:
1. Sensors have been added to the system after system implementation.
Corrective measures:
• Check the sensor connections of the I/O unit indicated by the fault code and the
programmed confi guration in the INFO mode (see Chapter 3.4.1).
• If the number of sensors in the I/O unit is higher than the number given by the master
unit, re-confi gure the system (see Chapter 3.4).
2. A sensor connected to the system or its wiring is faulty.
Corrective measures:
• Check the confi guration in the INFO mode (see Chapter 3.4.1)
• If the number of sensors in the unit is lower than the number given by the master unit,
check the unit wiring visually and tighten the connections.
• Confi gure the system (see Chapter 3.4)
• If the system still cannot fi nd all the sensors, disconnect the sensor wires one at a time
and confi gure the system after each disconnection.
• Once you have identifi ed the faulty sensor, check the wiring and replace the sensor,
if necessary.
NOTE! The current I/O unit normally indicates three sensors, even if the number of current transfor-
mers connected is only one or two.
