Integration in radio systems
Activation and integration in radio systems
EN
The radio transmitter of the WF.636.. is automatically activated after a
fl ow of 50 litres, but without transmission of installation. Alternatively, the
radio transmitter is activated by the WFZ.PS triggering tool for radio tel-
egrams or the parameter setting software ACT50 and WFZ.IrDA-USB.
walk-by (mobile data recording)
12 minutes after the radio transmitter has been activated, the WF.636..
transmits control telegrams so that a control readout can be carried out
after all devices have been installed. The the WF.636.. transmits regular
walk-by telegrams.
AMR (automatic data recording)
After the radio transmitter has been activated, the WF.636.. transmits in-
stallation telegrams for integration in the AMR network. Then the WF.636..
transmits regular data telegrams and statistics telegrams depending on
the radio mode set.
Parameter-setting possibilities
Parameters are set for the WF.636.. using the parameter setting software
ACT50 and WFZ.IrDA-USB. The following settings can be made:
• Switch display levels on and off
• Activation of leak detection and setting of the threshold value for leak
detection
• Setting of the next due date
• Switchover of radio mode (C-mode ↔ S-mode)
• walk-by settings:
