10.2 Output
10.2.1 Output signal
Relay, transmitter power supply (standard)
Current, voltage, pulse, intrinsically safe transmitter power supply (option)
10.2.2 Signal on alarm
No measured value visible on the LC display, no background illumination, no sensor power
supply, no output signals, relays behave in safety-oriented manner.
