7 Servicing/maintenance
The servicing has to take place according to the guideline VDE 0833.
A Windows PC (Windows XP or later), which has the current TAS-Link software of the according TAS-Link trans-
mission devices installed to it, is crucial for checking the TAS-Link transmission devices. Additionally, a USB con-
nection cable is needed to connect the PC/notebook with the transmission device.
Following a guide for the servicing / maintenance:

Read out the configuration data from the transmission device and save them on the PC.

Check the software version, in relation to published manufacturer specifications. If necessary, update the
software.

Checking of the supply voltage (230V power adaptor).

Simulate a mains failure at emergency power supply (battery) and test the battery operation.

Is a change of battery necessary? Check the manufacturer specifications regarding durability and docu-
ment these. Caution! RISK OF EXPLOSION IS REPLACED BY AN INCORRECT TYPE. DISPOSE OF
USED BATTERIES ACCORDING TO THE INSTRUCTIONS.

Check the function of the sabotage equipment (at TAS-Link in the system housing) (cover contact/drill
through protection).

Check the availability of the transmission paths (commissioning test, helpdesk).

Read out the event memory to see possible failures of the transmission paths. At redundant paths, disrupt
every path on its own and check the behaviour.

At GSM transmission devices check the signal strength and read out the event memory to see variations.

Check the time in the TD. If no synchronization via the transmission path(s) is possible, set manually, if
necessary.

Check the function of wired inputs and outputs.

Create test reports to the NotrufServiceLeitstelle (NSL).

Check the transmitted reports in terms of their content and their time stamp and align them with the NSL.

Test of the system reports. Align check of the reports with the NSL and control of the entries in the event
memory.

Check the event memory for irregularities.

Analyse fault reports in the event memory.

If available, check the function of additional services such as voice or SMS reports.

Optical check connection technique and mechanics, placement of the battery, antenna etc.
