Connection Requirements; Warning; Maintenance Advice; Troubleshooting - Pfannenberg DS5-SIL Instructions De Service

4.15. Connection requirements

Electricity and voltage limiting measures must be implemented in the superior system for the supply as well as
for the fault report interface.

4.16. Warning

WARNING Detriment to hearing
In order to avoid a detriment to hearing, when working directly next to the sounder, ear pro-
tection is to be worn.
DANGER Danger of electric shock!
Before all work on equipment, the following should be observed: switch off the equipment
before opening. All work on the equipment is only to be carried out by authorised technical
personnel

4.17. Maintenance advice

The sounder does not require any special maintenance. However, the 'proof test' interval should be observed.
Changes, modifications, faulty and incorrect use as well as not observing the advice of this operating manual
void the warranty.
External cleaning should be done with weak soapy water without use of solvents.

4.18. Troubleshooting

Despite high functional safety, faults can occur during use. These can have consequences in the sounder, in the
operational voltage supply or in the evaluation in the control system.
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 gener-
ated 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 0 and carried
out during the 'proof test' in section 4.9 can also help a lot.
If the sounder is defective, it should be repaired in the production plant. Only original replacement parts can be
used as replacements.
Faults that affect the functional safety are to be reported to the manufacturer. For a smooth process, please use
the form attached and send it to the following address.
You can reach the service or technical support on +49 (0)40 73412 -0.

4.19. Disposal

Recycling of the device can be carried out by specialist operations. The electronics can therefore be easily re-
moved from the housing. The housing material is made from aluminium die casting and the magnet from ferro-
magnetic material.
Should you not have an opportunity to dispose of the old device correctly, please speak to us about returns and
disposal.
The device at hand is not subject to the WEEE guideline 2002/96/EC and the respective national laws. The
