6 Commissioning / ShutdownIn any event, offset calibration should previously have been carried out under operational(warm) conditions. It is necessary to ensure that ambient air is present at the measurementsite. If this is not ensured, the probe must be dismantled again for the offset6.4 Setting up Service Warnings6.5 ShutdownService warnings 1 and 2 are designed to draw attention to regular servicing. The service warnings can be freely defined by the operator, e.g.Service warning 1 check probeService warning 2 dismantle and clean probeThe appropriate cycle times can be specified via the parameters 1260 and 1261 in the range1 to 65535 hours.In order to be sure to avoid damaging the LS2Lambda probe's ZrO 2 measuring element, theprobe must be dismantled before the system is shut down or immediately after the supply voltageis switched off.WARNING!Dismantle the Lambda probe before shutting down the measurement system.Caution: hot!NOTICE!Once dismantled, the LS2 Lambda probe can be stored indefinitely. The zirconium element isonly consumed during operation (measuring cell at operating temperature). This also applieswhere a probe has already been used previously.36
