 22 Switching behavior and signaling
Point level at two tanks
• 1 sensor connected at input channel 1 (terminals 7 and 8)
Relay output of channel 1 output switches in accordance with input channel 1
• 1 sensor connected at input channel 2 (terminals 33 and 34)
Relay outputs of output channels 2 and 3 switch simultaneously in accordance with
input channel 2
Fault signaling for input channel 1 is switched off.
Fault signaling for input channel 2 is switched on.
