Commissioning

Setting the communication converter
The configuration (selection of the interface and the transmission speed) of the communica-
tion converter is performed automatically. The transmission mode (synchronous/asynchro-
nous) is selected via the pushbutton (for details see section "Display and operation",
paragraph "Pushbutton").
Test mode:
Switching into test mode is accomplished via the pushbutton and signalled by the flashing
of LED 1 (for details, see section "Display and operation").
The test function is designed for easy commissioning or for service tasks. In this operating
mode, no signals pass through the communication converter (Figure 12). The signals
applying at the interfaces are looped so that parts of the entire communication path can be
checked.
The "Life Contact" relay is not energised in test mode.
