7.3 - PHW200 SIGNALS
The PHW200 wireless photocells work in the following operating states:
• Searching for a radio interface: when the battery is inserted, the device 
searches for the WM100 it was linked to, or for a new one in programming mode.
• Programming: if a new WM100 interface is found that is listening for new 
devices, it enters programming mode; it remains in this state until a system is 
actually created.
• Standby: the device enters “low consumption” mode; a signal is provided if the 
battery is low.
• Manoeuvre: the device enters a continuous communication phase with the 
WM100 interface; there are signals on the status of the optics, battery and radio 
coverage.
The led signals and their meanings are described in the relevant instruction manual.
7.4 - “OPERATION CHECK” PROCEDURE FOR WIRELESS  
 DEVICES
After programming a system, you can make a diagnosis of all devices on the 
wireless network. It can be run at any time and allows you to ascertain the state 
of the photocells, the flasher and the quality of the radio signal. The procedure is 
activated as follows:
