They replace neither testing of the complete machine or system prior to initial com- missioning nor their periodic testing by a qualified person (see chapter 2.2 "Necessary compe- tencies"). The checklists contain minimum testing requirements. Depending on the application, other tests may be necessary. Wieland Electric GmbH | BA001133 | 04/2017 (Rev. A) -

In normal operation, the 7-segment display shows the number of the selected transmission channel. In addition, it helps during the detailed error diagnostics (see chapter 11 "Trou- bleshooting") and serves as an alignment aid (see chapter 8.2 "Aligning the sensor").

- Page 25 Depending on the machine construction, stepping behind protection, e.g. using a second hor- izontally arranged safety light curtain, is necessary. In most cases, it will be more appropriate to choose a longer safety light curtain which makes the additional distance C equal to 0. Wieland Electric GmbH | BA001133 | 04/2017 (Rev. A)
