Troubleshooting

Despite high functional safety, faults can occur during use. These can have consequences in the sounder, in the oper-

It is the responsibility of the plant operator to take suitable measures to deal with occurred faults.
The first measure can be to check the operational voltage, check whether an acoustic warning signal is generated and
check the position of the alarm relay contacts, depending on the operational condition of the sounder. The cause of
the fault can thereby be traced. A step-by-step function test as described in section
'proof test' in section 4.10
If the sounder is defective, it should be repaired in the production plant. Only original replacement parts can be used
as replacements.
